Food bikes: a low capital, low footprint alternative to food trucks

2014 April 29

The Food Bikery seeks to prove that food bikes are a safe, legal, low-capital, and low-footprint alternative to food trucks. In transitioning mobile food off of trucks and onto bicycles, the Food Bikery will stimulate economic opportunities for low-income citizens of the East Bay who would like to start mobile food businesses. We envision that the cost of a food bike can be $5,000 or lower, which is an order of magnitude less capital investment than an average food truck ($50,000) and two orders of magnitude less capital investment than an average restaurant ($500,000). Given that a person can potentially run a food bike business as a sole entrepreneur, we estimate the profit would be enough to make an hourly wage in the range of $20-30.

Food bike cost

In addition to the economic benefits, food bikes can offer these benefits to local communities:

  1. Decrease fossil fuel consumption and climate change emissions
  2. Improve use of community space
  3. Increase physical well-being and health and foster awareness about the power of bicycles
  4. Increase awareness about where food comes from and how it is prepared

The Food Bikery has been launched as an entrepreneurial idea by myself and Jason Trager (a soon to be minted UC Berkeley PhD mechanical engineer and bike enthusiast, to say the least). We have applied for a grant from the UC Berkeley Big Ideas competition, and we should be hearing about that soon. I put in a couple months of research and interviews into the grant application. In doing so, I met a handful of food bike enthusiasts who are featured in the short film above, including Curbside Creamery, El Taco Bike, and Apothocurious/Hot Bike, the last of which I’ve written about before. Additionally, I have done more in-depth research on the code for mobile food facilities. Essentially, if you’re cooking food on a bike trailer, you are subject to line item requirements of refrigeration, three sinks, and 20 gallons of water in order to meet code. That’s why you don’t see food bikes doing any cooking at public events and markets. The ones that exist serve hot or cold pre-packaged foods at public events or simply cater to private events. We want to see a food bike that can cook at public markets, while still being safe, legal, and healthy.

In order to move forward on this project, we are requesting a grant from the Big Ideas program to build a prototype food bike, engage in policy lobbying, and pursue permitting processes to ensure that food bikes can legally operate in the East Bay. If you stand with us, please vote for our project for the Big Ideas video contest, the winner of which will get an additional $2,500 cash prize to go towards their project.

BERC Cleanweb Hackathon 2.0: Smarter Sprinkler saves water and takes top prize

2014 April 29

Hackathon-group-1024x682

Building off the success of last year’s hackathon, BERC successfully threw its second annual “cleanweb” hackathon this past weekend. The result was four new apps to help analyze and reduce home water consumption, food-related water footprints, and commercial building energy consumption. You can find complete information on the contestants and winners here, including teammates, concepts, and screenshots. Photos of the hackathon can be found here.

The winner “Smarter Sprinkler” combined a compelling water conservation concept with some adept software and hardware hacking. The team, consisting of three LBNL scientists (Anna Liao, Daniel Olsen, Andrew Weber) and one local software developer (Robert Sadler), worked hard all weekend to build a combination of open source hardware and software to make intelligent home irrigation schedules based on current weather, drought, seasonal, and user-based information. Given that half of household water consumption happens outdoors, this new app will give homeowners the ability to take control of their water usage. They expect their solution to be compatible with at least 90% of existing sprinkler controllers, and the app interacted with a “simple measurement and actuation profile” (sMAP) driver and server, which is actually a type of protocol developed here at UC Berkeley.

Another innovative app to help conserve water was a tool to help people plan and optimize their dietary choices based on the water footprint of their data. Developed by two developers from QE-Design, they used some fun concepts from Captain Planet to lighten the mood at the hackathon, even though they did some serious data wrangling with USDA and Water Footprint Network datasets. Greenvite, the winner of the energy challenge, allowed users to save energy in conference rooms, by reducing heating/cooling consumption in unused conference rooms and by allowing building occupants to compare the energy use of a conference room at different times.

This year, the hackathon included “skills sessions” on open data standards, using API’s, web app frameworks, and Javascript visualization, which created a space for learning and sharing skills in addition to the usual innovating and coding. The hackathon also showcased the recent launch of two BERC communities, Cleanweb Berkeley and infoEnergy Nexus Working Group.

BERC would like to extend special thank yous to our sponsors for making this event possible includingGenabilityIBM Smarter PlanetWaterSmart Software, and Imagine H2O, as well as our event volunteers and mentors including Andie Mercado, Yang Ruan, Peter Minor, Peter Alstone, Anna Schneider, Dav Clark, Michael Cohen, Justin Trobec, Jolie Chan, Sherry Wu, and Dan Sanchez, who helped plan, run, and enrich the event for all attendees.

Will Hampton Creek Foods make our food system sustainable?

2014 April 7

Cracking the Egg

People consume unhealthy food (think a McDonald’s Big Mac) because it is cheap and it tastes good. The founder of Hampton Creek Foods, Josh Tetrick, asks what the world would look like if healthier food was always the most affordable while still being delicious. He believes his company can make plant based proteins, with similar properties to animal-based products, at a lower cost. And he makes the meat industry out to be an easy target: wasteful, unsustainable, cruel, and riddled with increasing costs. And he has just been armed with an additional $23 million in investment from Li Ka Shing, whose name you might recognize from our campus’s Biomedical and Health Sciences building bearing his name.

Over 1.8 trillion eggs are consumed per year worldwide, and 99% of them come from caged chickens. Intensive meat production systems like caged chicken eggs are responsible for one third of the world’s energy use. The ratio of energy input to useful food energy (calorie) output is 39:1, Hampton Creek claims. Yet if try to make this process more sustainable by taking the chicken out of the cage, prices rise 30% and Hampton Creek is working off the assumption that the majority of people won’t pay higher prices for cruelty-free products. They think the best way to solve this problem is just to take the animal out of the picture. “It’s not a vegan thing. It’s not a vegetarian thing. It’s just a smart thing,” Tetrick says. He is convinced he has to make any egg substitute cheap and convenient. And he claims he can bring that energy input output ratio down to 2:1 with Hampton Creek’s plant based egg.

The egg has 32 different uses, from your ordinary scramble to cookies and cakes to creamy mayonnaise. Can it be replaced with a plant?  Tetrick throws around verbs like bind, aerate, and emulsify to describe his desired attributes. They’ve looked at 3000 plants and chosen 11, he claims. A specific variety of the Canadian yellow pea seems to hold the secret for making a creamy mayonnaise, their first product which has already hit shelves in Whole Foods, Bi-Rite Market (a notable organic grocery in SF), and -soon- Safeway. They want to be in 25,000 stores by the end of 2014.

“The problem with the conventional egg is that it’s not getting any better.” There are five factors driving demand for Hampton Creek’s egg product: 1) rising and volatile egg ingredient costs, 2) sustainable eating driven by millennials, 3) cholesterol, 4) food safety, 5) and the fact that 34 million people in the US have egg allergies or sensitivities. Their product seems to satisfy all criterion and they claim to be 48% more cost effective than conventional eggs already, $0.39 vs. $0.76 for the equivalent of a dozen eggs. They will be launching cookie dough and scrambled egg products soon.

They are certified as non-GMO (otherwise they wouldn’t be on Bi-Rite shelves). They use only ingredients that are “GRAS”-certified, or generally regarded as safe. So what is the catch? Does all of this sound too perfect? Some of their ingredients are organic and some aren’t. They admit that if they used solely organic ingredients, then their egg product would be 30% more expensive than the conventional egg. Yet, while their might be some drawback with respect to this organic aspect, the product seems to win from energy, carbon, water, health, and cost metrics. Are their pitfalls to these “lab-based” foods that we aren’t seeing? Is it GMO 2.0? Is it still promoting homogenous food production that stifles biodiversity?

California’s classic chart: what really caused the energy savings?

2014 April 1

ca curve

Arik Levinson of Georgetown University presented a controversial paper at last week’s POWER conference hosted by the Energy Institute at Haas, entitled “California Energy Efficiency: Lessons for the Rest of the World, or Not?”. The subject of his paper was a graph that has been well shown around the world of energy policy. The California Energy Commission, former Secretary of Energy Steven Chu, the World Bank, New York Times, Natural Resources Defense Council, and others have all used this graph to help explain the importance of energy efficiency standards (for equipment, appliances, and lighting) in flattening California’s per capita electricity use.

Levinson contends that it actually does not have lessons regarding such energy efficiency standards and the divergence in the paths of California and other U.S. states is mostly due to other demographic patterns, including climate, income, population, and housing characteristics. However, many critics have attacked Levinson as being against efficiency regulations. He emphasizes that his paper is not a critique of such standards and regulations, but rather serves to shine light on the actual reasons for divergence in energy use patterns and expose the need for other evidence of the efficacy of efficiency standards.

There were four reasons for Levinson’s initial suspicion of this graph: 1) other states and the federal government followed with similar regulations soon after California, 2) appliance manufacturers generally followed the California standards nationwide, 3) the gap started before California’s standards were implemented, and 4) the five other states (NV, OR, WA, ID, HI) with the slowest growing per capita energy use after California are all neighbors of California.

His analysis showed that population migration accounted for 15% of the difference, climate and income accounted for 20% of the difference, and population and housing characteristics accounted for 61% of the difference. For migration, he pointed out that between 1960 and 2010, there were major shifts in U.S. population from the north and the midwest to the south and the west, and so he compared California to a control group that was weighted with the new population distribution. For climate and income, he showed that California’s mild climate means that there was less of an increase in heating and cooling needs than in other states. Finally, he noted that California household have grown relative to the rest of the U.S. (California’s household size decreased by only 0.16 members while the rest of the U.S.’s decreased by 0.76 members) and since energy use per capita declines with household size, this clearly played a big role in the flattening of California’s per capita energy use. In the end, these three trends accounted for 88% of the divergence, leaving only 12% remaining that may be due to regulations (or other reasons).

This paper is certainly throwing a lot of cold water on the long-claimed victory of California’s energy efficiency standards’ role in energy savings. But, it does not necessarily mean that standards do not make a difference. After all, it did seriously influence manufacturer behavior as well as other states and the federal government to implement their own efficiency standards. If it weren’t for all of these standards, per capita electricity use would most likely have been higher for both California and the rest of the U.S. Proving these counterfactuals (and how much higher electricity use would have been) is very difficult, and so Levinson’s call for such evidence may not be answered.

New coal capacity growth in China is finally slowing…

2014 February 28

china cap add

Just a quick note, which I may expand on later… It is an encouraging sign that coal-fired power additions are finally slowing in China (though still growing in absolute numbers), with 2013 being the first year that there has been less than 50 gigawatts of coal capacity addition, and with China Electricity Council’s 2014 projection, it looks like it may stay that way moving forward. Certainly, the rainbow “fan” that is replacing these additions is also encouraging in some respects. Wind capacity additions should remain steady in the years ahead, while solar continues to have a couple of aggressive years ahead of it. Nuclear power should be picking up the pace in the lead up to 2020, while hydro will have a couple more years of >10GW additions before slowing down, as China reaches the technical hydropower potential of nearly all of its rivers. Whatever it can dam, it is damming, including the Nu River, which I made a short film on in 2008. My last point for now is that China has now had six consecutive years of ~90GW capacity additions, but since the growing majority of these additions (hydro, wind, solar) run at lower capacity factors than coal, the overall power generation (and consumption) is slowing too, due to slower economic growth, some energy efficiency efforts, and perhaps some structural change as well.

How to track your real-time residential energy usage

2014 February 11

pge1

In January, I attended a “data science and sustainability” meetup held at OPower. The topic was “Driving Behavior Change with Energy Insights”. To make a long story short, one of OPower’s business models is to take over a given utility’s billing structure and provide customers with easy to understand information on how much energy you use compared to neighbors with similar homes. This method is based off of a study where statisticians hung signs on people’s doorknobs to save energy. One said, “Save energy, it saves you money.” Another said, “Save energy, be a good citizen.” And the last one said, “Save energy, it’s good for the environment.” Apparently, none of them worked in convincing people to use less energy. They tried one last doorknob hanger: “Your neighbor uses less energy than you.” And voila! Statistically significant energy savings were realized over time, simply because of this message. OPower has used this concept in their billing. If you access your PG&E bill online, you will see something like the graph above (note: this is only for electricity, and not for gas), comparing you to “all similar homes” (for me, it was single family homes of a similar size that use natural gas for heating and are within half a mile). The “efficient similar homes” are apparently the lowest quintile of energy consumption. It may well be that those homes have less people living in them. Or perhaps they are simply greener than Sustainable John.

But not for long! Let’s see if we can save some energy around the house. PG&E was actually one of the first utilities to take on the “Green Button” initiative, an effort to release basic household energy data to customers in usable formats. The initiative was supported by the Department of Energy and even the White House. Essentially, you can have data about how much power your house uses in 15 minute, hourly, daily, and monthly increments. However, the data is not in real-time, rather it’s a few days old (on a Tuesday night, I can have access to data through Sunday night). DOE supported a bunch of hackathons around this initiative, which launched dozens of app ideas and a couple companies along the way, one of which is Bidgely. Bidgely has a service where you can input your utility log-in information, and it will analyze your home energy usage in more ways than PG&E’s site can. It’s easy to pull up your monthly energy use, broken out by each day.

bidgely1

 And then you can click on a particular day and see hourly interval data, with some helpful daily average consumptions. Now, you can begin to see the patterns of roommates bustling to get ready in the morning and coming home in the evening, which is when utilities commonly hit their peak loads.

bidgely2

In fact, the smart meters that PG&E has installed in nearly all of their service territory are collecting many more data points than this. And now, due to a device called a Home Area Network (HAN) device, customers can now get now get access to this data. I just installed my HAN device this past weekend, and now am collecting real-time energy use data in 5-minute intervals (seen below), which is a big improvement over the hourly interval above. I can now know how much energy the house is using at any given time. At 7:20AM, I was in the kitchen using the lights and the toaster. At 8PM, I was using the clothes washer and dryer. As this data is captured, Bidgely is analyzing it using different algorithms, to understand how much of my usage is due to the various appliances in our household: refrigeration vs. vampire loads vs. clothes dryers, for example. The granular data will eventually help me to sort out where I can focus my energy efficiency efforts, whether it’s in more efficient lighting, tackling vampire loads, or getting rid of that old, clunky fridge.

bidgely3

If you would like to track your energy usage, a good place to start would be to make sure you have your PG&E online profile set up. Then, you can sign up for a service like Bidgely. They even have a mobile app (iPhone and Android), so it’s easy to track your hourly interval data. If you want to buy a HAN device, you can find more information on PG&E’s recently launched HAN device portal. The one I bought was pretty steep, about $100 in cost. But, you could maybe convince Bidgely to send you one for free, and hopefully they’ll come down in cost over time. If you don’t live in PG&E territory, check to see if your utility is signed on to the Green Button initiative and whether or not they have deployed smart meters.

In OPower’s presentation, they revealed that their comparison methods had resulted in verified 2-3% energy savings on average per customer in the territories where they are working with utilities. While this number is certainly nothing to cough at, it does suggest that there is a still a huge potential for energy efficiency out there. And companies are piling in to the residential and small commercial energy efficiency space to capitalize on this influx of data and see if customers will act on it. Besides Bidgely, there’s Simple Energy, PlotWatt, Ohmconnect, and also WattTime (a winner in last year’s hackathon). BERC is also beginning to participate in this data revolution. Stay tuned for forthcoming information on two new BERC Communities, Cleanweb and InfoEnergy Nexus, as well as the second annual Berkeley Cleanweb hackathon to be held on April 18-20, 2014.

My first JavaScript app: building a newsletter with Google Apps

2014 January 14

google app scripts

Well over a year ago, I made a promise to start committing more time to learn how to code. I jumped into Codecademy for a number of months, primarily January to March of 2013 (putting in about 1 hr/day for 5 days/week). I focused on JavaScript at first, but then started to poke around with a little Ruby and Python, as my friend Andrew and I developed a mockup for a Facebook contest (something else I need to write a long-overdue blog post about).  Then, I was the co-organizer of a hackathon in April, which went really well. But, I wasn’t using the skills I had learned in Codecademy that much. It’s hard to make the jump from Codecademy into building a whole website or new project. You need a sort of pet project to help you get comfortable, before you take a bigger leap. Codecademy teaches you a lot of useful things about basic programming concepts and basic syntax (grammar for computers) for a number of languages. But I wasn’t applying the skills to a concrete project. By the time fall (quickly) came around, school had started and I had little free time. Not only had I not applied the skills I had learned in Codecademy, but now I was forgetting the syntax I had learned.

Over the winter break though, I discovered Google Apps Scripts, a JavaScript group of “libraries” (lists of useful functions and methods)  that lets different Google Docs talk to each other. I’ll be honest, I kind of hate working in Google Docs. They’re often very slow, and the formatting tools are hardly a fraction of what’s offered in the full Word/Excel/PPT programs. But they are useful for certain things. In my new position as VP of Membership for the Berkeley Energy and Resources Collaborative, I have to format and send out a weekly newsletter about energy events on campus (there’s a lot!). People send me things they want to include in the newsletter. The formatting takes a long time. Cutting, pasting, organizing, writing blurbs, summarizing. Ain’t nobody got time for that!

Well, now everyone can take a couple minutes to fill out a simple Google form, if they want to include something in the newsletter: Name of event, date, time, place, description, and a link. Simple. This goes into a spreadsheet automatically. Using Google Apps Scripts, I can write my own JavaScript program to automatically format those spreadsheets entries into a Google Doc that looks like a newsletter, all with the click of a button. I can look it over and make minor edits, then send it on its way. This will likely save me 1-2 hours per week, which is valuable time in grad school. Now I’ll describe some of the basics of how this program works.

First, I need to gather all the data from the spreadsheet and store it in a Javascript variable so I can access it and manipulate it.

var sheet = SpreadsheetApp.getActiveSheet();
sheet.sort(3);
var rows = sheet.getDataRange();
var numRows = rows.getNumRows();
var values = rows.getValues();
for (var i = 0; i <= numRows – 1; i++) {

var row = values[i];
Logger.log(row);

}

I got most of this code, just sniffing around some of the examples on Google’s site. That’s one great thing about coding. Someone has likely already tackled the problem you are trying to address. So just have a look around the interwebz for some guidance when you’re stuck. The code above simply uses some existing JavaScript methods like getValues and getNumRows (see here for a huge list of methods). Oh and also, a sorting function to put all of the event submissions in order. Then, there is a “for loop” to go through all the rows in my spreadsheet, and stuff the data into one variable called ‘values’. What’s amazing about Javascript is that you can stuff different types of words and numbers into one variable (not possible in other types of languages which only like one data type in variable/array), and it will just store them in an arrayed structure. Since, I have six columns (event name, date, time, etc.) of information, it will be useful for me to call just a specific column of info when I need it.

Now I can make the newsletter.  When I run the script, it uses a method called DocumentApp.create to immediately create the new Google doc newsletter for the week. I poked around the other library of functions available for Documents. I basically just need to create a heading for the newsletter, make a list of events at the top (like a table of contents), and then run through the details of each event. The functions ‘setHeading’ and ‘appendParagraph’ seem to do the trick. Now I just need to call the right data from the ‘values’ array, with some help from a ‘for loop’ to help me run through all the individual events (in rows). Ok, I need to list the event time which is in column 2…that’s easy, it’s just ‘values[j][2]‘ where j is my dummy variable for the rows/events I’m running through in the for loop and 2 is the column I want. As you can see in the top picture, most of my code is calling the values array in some form or another. There are some other tricks in there, but it’s not too difficult. Though I will admit, I spent the better part of today, writing only 90 lines of code or so. There were certainly moments of frustration, but for now, it works and that’s what’s important. Next Monday, I’ll make the first newsletter of the semester with the click of a button. I hope it doesn’t blow up!

Most comprehensive databook on China’s energy production and consumption released!

LBNL’s China Energy Group has released the 8th version of its China Energy Databook. I was the co-editor for this version, and learned a lot about how to hunt for different kinds of energy related data on China. We usually do an update only every couple of years, but hopefully we will be doing more regular updates as we streamline our processes. Certainly, this project has a legacy that we must continue. This is one of the spreadsheets from the databook, started 13 years ago by Yang Fuqiang, who at the time was a scientist at the lab but is now an adviser to NRDC’s China program.

yang ceg

Let me know if you have any questions or suggestions for the databook. I’m currently working on a Sankey diagram for China’s energy consumption and production (a la LLNL’s famous versions for the U.S.) and hope to show that off in the coming weeks.

If you get the chance, go to the ECEEE summer study on energy efficiency

2013 June 15

In early June, I had the privilege to attend the European Council for an Energy Efficient Economy (ECEEE) summer study in Hyeres, France (it’s every other year) and give a paper that I wrote with Chris Marnay and others on microgrid program development and policy. My mom came along with too. We had an outstanding time. A day in Paris on either end, and 5 days in the south of France. Literally, the weather every day was sunny and 70F. Two other awesome things happened on the trip. First, I got to take the high speed train. It only took 4 hours to travel the entire length of France and the scenery was so lovely, just gentle rolling hills until we eventually happened upon the azure ocean in Toulon. The marvels of efficient train travel! The second thing was that I ran into my professor Iain MacGill of UNSW, Australia where I took a summer course on renewable energy 9 years prior (the course still exists!). Here we are happily reunited.

The mornings were filled with great talks and academic exchange on energy efficiency. The afternoons were filled with sunshine, paddleboarding, kayaking, swimming, and bicycling. It really was a perfect experience.

“Bike Shop” + Climate Ride: This is Climate Awesome…

2013 May 30

Just a week before my Climate Ride, I put the finishing touches on my new music video, called “Bike Shop/Climate Awesome” featuring Ace (aka Akabar, my little brother with the Big Brothers Big Sisters program). Here it is:

After I posted the video, my fundraising basically doubled from around $3,300 to over $6,600. I believe I ended up in 8th place in fundraising out of over 150 riders. I got a special top ten Jersey as well as the award for the most number of individual donations, the official count was 129, but I think it was around 250 if you count every jian bing I sold to raise money. It was an incredible feeling to have so many people support my ride and this cause and I am incredibly grateful to them. Here are some charts on my fundraising efforts, the timing of my donations, and the size of donations I received. I believe these data can potentially be helpful to note for other climate riders. I should do a longer post about fundraising tactics. I had several.

dates fundraising

The ride itself was incredible. We had 5 days of nearly perfect weather. I’d estimate about 4 hours of cloudiness. We had strong tail winds on day 3, which was the day we did 100 miles in one day. It felt incredible! Towards the end of that “century” day, we had the most incredible and beautiful climb in Mendocino county. It was so invigorating and empowering. Just check it out. And yes that is Harry Mud Mudd!

climb

The people on Climate Ride and the organizers were all so amazing. It was a fully supported ride with food and everything. Each campsite we stayed in was a large campsite, so most of them had a general store out front, so when we rolled into camp we could also just grab a six-pack and start kicking back! Though I would ride periodically with people throughout each day, most of my actual riding was by myself. I could stop and take photos. I could just let my mind wander. I could just enjoy this wonderful scenery and experience. I had a great tentmate, my friend and former colleague Puneeth, and on the last day my good friend Nick made it out from Berkeley to meet us for the final leg. He took this great picture of me. I think it’s my favorite from the ride.

As we rolled into SF Civic Center, I got all of the Climate Riders to do a call and answer eco-rap with me. Enjoy!

How to educate your Berkeley neighbors about going solar

2013 May 8

orange_on_white_wide

The DOE Sunshot Initiative aims to get solar PV costs down to $1 per watt by 2020. Module prices have already fallen precipitously and continue to fall. However, an increasing number of companies are focusing on how to bring down the marketing, finance, and installation costs of solar PV systems, which remain stubbornly high. LBNL research has shown that customer acquisition is 10 times more costly in the U.S. than in Germany (see slide 29 in the linked presentation).

Two friends, my former colleagues at Bloomberg New Energy Finance, are pursuing an idea called SolarList, which aims to reduce those customer acquisition costs here in the U.S. One problem is that solar installation companies burn through a lot of sales time educating potential customers about how to go solar, but only a few of those leads end up working out. SolarList is building mobile software that allows students to offer free, third-party home solar assessments through targeted canvassing and their personal networks. For homeowners that are still interested once they have had some education and a free assessment, SolarList can connect them to installers.

A couple weekends ago, some friends and I decided to do some beta testing for SolarList’s mobile solar assessment software in the hills of Berkeley. We wanted to see just how homeowners would respond to some Berkeley students knocking on their doors offering free education on going solar. I was joined by Michael Conti (SolarList), Tim Cronin (BERC’s VP of Law), and Jenny Tang (editor of BERC’s China Focus).

Together, we knocked on a couple hundred doors that weekend and talked to dozens of homeowners. We found that if someone answered the door and had a few minutes to talk, the conversation went well at least 50% of the time. In general, people enjoyed receiving a free solar assessment, seeing how much they could save on their utility bill, and learning more about the different financing and installation options available. Some folks even offered to sit us down at the dining room table and have a longer chat.

At the end of the day, we had actionable leads that we could sell to solar installers. The homeowner receives free education and assessments, solar companies get qualified leads, and we get paid for pounding the pavement and preaching the solar gospel. (One homeowner remarked that she was only willing to talk to us because we didn’t look religious. She gets a lot of evangelists at her door, but I was apparently the first solar evangelist.)

So that’s how you can sell solar to your neighbors in Berkeley (or wherever you live). If you want to try it out, SolarList’s Ground Forces team is ramping up with summer jobs.

Twitter/thermostat mashup takes top prize at inaugural Berkeley Cleanweb Hackathon

2013 May 2

IMG_4993-small

This past weekend, UC Berkeley threw its first inaugural “Cleanweb Hackathon” with a coalition of campus sponsors and corporate partners. Pizza, beer, and soda were consumed in large quantities in the foyer of Sutardja Dai Hall while participants “reduced tons with zeros and ones”. The result was five amazing new apps to help you analyze and reduce energy consumption at home, switch to greener sources of power, plan your EV route, and meet people on BART. Find complete information on the contestants and winners here, including teammates, concepts, and screenshots. Photos of the hackathon can be found here.

The winning app “Thermostatly” took home prizes for best overall app and best smart home app (a total of $1500 in prize money). It’s an app to remotely control your thermostat using hashtag keywords on Twitter. Teammates Patrick Huck, Kushan Patel, Omer Shalev, and Aayush Daftari not only had a great business concept, but also built a working prototype in 24 hours! Using a hashtag such as #inc3 could increase your thermostat by three degrees on a hot day, when the utility is having difficulty meeting load. The challenge originally suggested at the beginning of the hackathon was to simply use SMS to control the thermostat, but the team’s innovative use of Twitter may enable crowdsourced demand response and greater levels of energy saving, as many followers will see and potentially replicate actions.

The prize for best app in the transport theme went to “Friends on the Go”, which enabled people with similar interests to meetup on BART for networking, friendship, or dating. The app’s creators hope to increase the use of public transit by enabling people to meetup while commuting. The prize for best app in the “green button” theme went to “wattTime”, which seeks to let you know more about the electricity you use and alert you when it will be coming from clean sources of power.

Other submissions included the “Green Button Grade” to help homeowners analyze Green Button data and data coming from Home Area Network devices (provided at this hackathon by Rainforest Automation) which are very new to the market. Lastly, the impressive code base behind “EV Route” used an API of locations for EV charging stations and a given EV range (say ~100 miles for the Leaf) to calculate on Google Maps how you might get from point A to point B with stops to recharge. The results were illuminating. It’s currently quite a circuitous route from Berkeley to Los Angeles.

The hackathon was an all-around success due to the dedication of the participants. Special thanks are also in order to the main sponsors: LBNL, Carbon Cycle 2.0, CITRIS @ UC Berkeley, and The Foundry @ CITRIS, BERC, and EnerNOC, as well as our technical partners: Rainforest Automation, PG&E, SFMTA, Radio Thermostat, Enervee, and PlotWatt who provided technical guidance, judged the entries, and spoke about software challenges in their respective sectors. Lastly, I’d like to give a shout out to Jolie Chan, the “sustainability soldier” at CITRIS, without whom I would have not been able to pull off this hackathon.

One judge Nate Ota of Radio Thermostat (and a CITRIS alumnus) remarked at the end of the judging, “I’d love to live a day with these apps, and see just how much they could change my life.” Hopefully, the hackers will continue to build on their visions, and these apps will be coming to a smart phone near you soon!

The cutting edge of (scary) climate science is here in Berkeley

2013 May 1

hh

Last week, I attended the Berkeley Lab “Science at the Theater Earth Day Event,” entitled  “How Hot Will It Get?” featuring five 15-minute talks by four LBNL scientists and one UC Berkeley economist. Overall, the event was a success, and the presentations were very informative, if not a bit frightening. The next “Science at the Theater” event is on May 13, so mark your calendars for “Eight Great Ideas”, where eight LBNL scientists will each have eight minutes to pitch their groundbreaking ideas. Here’s a summary of what was said the other night:

Bill Collins – What do computer models predict about the future of the Earth’s climate?

Since climate science started in the 1960’s, there has been nearly a billion-fold increase in computing power. This has enabled computers to become an increasingly powerful crystal ball for the Earth. Bill spoke about his visit to Australia for an IPCC meeting during the “angry summer”, where it was 120F in Sydney and 123 weather records were broken in 90 days. The 5th Assessment Report of the IPCC (AR5) will be released in 2014, and we can look forward to more well-informed (and more frightening) predictions of what is in store for our global climate. He noted that climate change through 2035 is largely already committed by the greenhouse gases we have emitted to date and the action we take now will dictate climate change in the latter half of the century. To date, this reality has been at odds with what has been politically possible on climate change. He ended with a quote from famous biologist E.O. Wilson: “A very Faustian choice is upon us: whether to accept our corrosive and risky behavior as the unavoidable price of population and economic growth, or to take stock of ourselves and search for a new environmental ethic.”

Margaret Torn – What happens to the Earth’s climate when the permafrost thaws?

The arctic is warming much faster than the rest of the Earth, and there is twice as much carbon in arctic soils as there is in the atmosphere. When the permafrost melts and the frozen organic matter beneath it thaws, the indigenous microbes will decompose that matter much faster, forming carbon dioxide and methane. As a biogeochemist, Margaret studies the dynamics of that decomposition in Alaska and how it will contribute to warming. She noted that the dynamics are complex and yet to be fully understood.  Bill Collins’ most powerful climate models don’t yet incorporate potential feedback loops from permafrost melt. One scenario is that the melting permafrost sends loads of greenhouse gases into the atmosphere, but shrubs also expand to new areas and increase carbon uptake. The overall effect on the “albedo” is yet unknown.

Michael Wehner – What does high performance computing tell us about heat waves, floods, droughts, and hurricanes?

“Climate is what you expect, and weather is what you get,” Michael said as he began his talk, attributing the quote to Edward Lorenz, the father of chaos theory. Michael studies the weather and increased risk of extreme weather (heat waves, cold snaps, drought, floods, hurricanes, etc.) from climate change. He estimates that the 2003 European heat wave, which caused 70,000 excess deaths, will happen in 9 out of 10 summers by the year 2040. That is, the risk change (over a baseline level pre-industrial revolution) for the event in 2003 was 2X. In 2023, the risk change for a similar heat wave will be 35X. In 2040, the risk change will be a startling 154X. This will equate to a probability of 90%. Yikes.

Jeff Chambers – How much carbon do our forests absorb and what if this rate changes?

Only 50% of the carbon we emit into the atmosphere stays there. The other half goes into the oceans, tropical forest sinks, and regular terrestrial sinks (soil and trees). Jeff studies what will happen to the forest and terrestrial sinks over time. There will be the effects a warming world, and the effects of specific weather disasters. He estimated that 320 million trees were destroyed in hurricane Katrina, which normally absorb a carbon equivalent of 105 million tons of carbon dioxide. Other impacts to forests include increased risk of wildfires, droughts, and pest infestations.

Maximilian Auffhammer – What kind of carbon tax might actually work?

“You know you’re at a nerdy event, when they bring out a German economist to close the show,” Maximilian quipped to begin his talk. Maximilian focused on what we might do to slow down climate change and potentially avoid some of doomsday. As a German economist, he is concerned about the costs of three things: 1) direct impacts (think hurricanes and floods), 2) mitigation, such as how to use less energy and produce more clean energy, and 3) adaptation. We can internalize the costs of climate change in three ways 1) regulation and standards, 2) carbon tax, and 3) cap and trade. The problem: about 200 countries have tried to negotiate a global agreement, it has not worked, there is no significant progress on the horizon, and any one country can block action. He proposes that the G20 (which account for about 80% of carbon emissions) agree to charge a significant carbon tax to start, say $20/ton to begin with. It would be enforced to non-compliers at the border (thus creating an incentive for other countries to adopt carbon policy). He says it would be much easier to negotiate than a global agreement, but admits it would still be pretty difficult.

1. California’s AB-32 climate change law: The organizations I ride for are protecting, lobbying for, and implementing the strongest climate change mitigation legislation out there.

2. UC Berkeley: I’ll be a student in a dual master’s program in energy and public policy in the fall, and right now I work on energy efficiency and distributed generation policy at Lawrence Berkeley Lab. The organizations I ride for are fighting for the same outcomes that I am studying and working towards.

3. Bike economy: The organizations I ride for include bicycle coalitions which increase the number of bikes on the roads and decrease the number of cars. They lobby for bike lanes and make sure everyone feels safe on a bicycle. They inspire me to keep expanding my food bike operation!

Have you seen “Thrift shop” (240 million views and counting)? Well, get ready for “Bike shop”! This new music video will debut on May 11 in support of my fundraising efforts for Climate Ride. If you haven’t donated yet, please do so now at this link! At the heart of Climate Ride are two groups that converge: 1) people that love biking, 2) people working to fight for a clean energy, low-carbon future. To that end, my new video will have one verse focused on how awesome and fun bikes are and one verse focused on how we, as citizens, need to lobby for that low-carbon future. I’m lucky I have such awesome friends to help out with my music video…the shot above gives a little taste of what is coming your way. This will mark my 6th official music video. The preceding five were: Copenhagen Rap (3-5-0), All We Need Is MPG’s, No Love (for the Upton Bill), Occupy Rooftops, and Low-Carbon (低碳) Style.

The formula behind ‘Chasing Ice’ and ‘The Island President’: visuals + heroes

2013 April 16

Chasing-Ice

Tomorrow April 16, BERC, ERG, and CEGA will host a *free screening* of the documentary Chasing Ice in Sutardja Dai Hall auditorium (register here), and I highly recommend you go see it. This film inspires climate change action because of its use of visual evidence and a protagonist hero with whom you feel a personal connection.

The film follows photographer James Balog, who founded the Extreme Ice Survey, the most wide-ranging ground-based photographic study of glaciers ever conducted. National Geographic showcased this workin the June 2007 and June 2010 issues, and director Jeff Orlowski brought this story to the big screen. Beyond showing the startling footage of the disappearance of glaciers over just a couple of years, the movie explains the technical problems that Balog faced in setting up his cameras and the personal struggles he had climbing ice and snow even after multiple knee reconstruction surgeries. His perseverance is inspiring, however, and the visual evidence he presents is beautiful, haunting, and motivating.

At the most recent screening in Berkeley hosted by local company Mosaic, Mosaic’s co-founder Dan Rosen explained how he met director Orlowski at the Unreasonable Institute where they inspired each other to continue pursuing their dreams. Orlowski dreamed of bringing the story of the Extreme Ice Survey to the big screen, while Rosen dreamed of fighting climate change by creating a platform for any individual to invest in clean energy projects.

Chasing Ice’s use of visual evidence and a protagonist hero mimics another climate change movie I saw last year, The Island President. I reviewed that movie at length on my personal blog due to its deep impact on me and its amazing storytelling. That movie followed the president of the Maldives, Mohamed Nasheed, leading his country’s fight against climate change. It showcased Nasheed’s personal struggles as a civil rights activist (being arrested, tortured, put in solitary confinement) and his true passion for saving his country from the threat of climate change and rising sea levels which will wipe out the country. It is summed up well in one of his quotes in the movie: “How can I promote democracy if there is no country to speak of?”

This level of personal storytelling is in great contrast to tactics used in An Inconvenient Truth, the most well-known climate change movie to date. That movie stumbled in its attempts to make Al Gore a personal hero (a cobbled attempt to make it personal by recounting his childhood on the farm and the tough loss of his mother to cigarettes and cancer), but instead focused on a comprehensive, yet accessible review of the data and science behind climate change. At the end of the movie, Gore called for action based on a moral crisis, but I simply wasn’t as inspired after I saw An Inconvenient Truth as when I saw Chasing Ice and The Island Presient. Gore understands what his previous slideshow lacked, and has recently altered its content to motivate audiences with both aspects of visual evidence and personal connections. It seems these tactics will become the gold standard for climate change movies, as the impacts of climate change begin to be seen and as filmmakers seek to more effectively motivate viewers to take  action against climate change.

Solar companies and utilities spar on ratemaking at Cleantech Forum SF

2013 March 26

solar2

Representatives of two solar companies (SunRun and Clean Power Finance), two utilities (SDG&E and National Grid), and a smart grid research firm (Pecan Street) sat down for a civilized discussion yesterday at Cleantech Forum in San Francisco. The discussion on distributed solar, power storage, and the evolving role of the utility quickly became a heated debate, dominated by Brian Miller (VP of Public Policy and Power Markets at SunRun) and Lee Krevat (Director of Smart Grid at SDG&E) with ample contributions from Bert Haskell of Pecan Street.

Pecan Street has the most detailed residential energy database on residences in Austin, TX.  Data includes what firms have fitted with the metering, rooftop solar, and electric vehicle charging stations. In one of their pilot studies, it was discovered that there are 200 homes with rooftop solar and 70 electric vehicle charging stations within one square mile, all connected to one transformer. This is likely higher penetration than seen anywhere else in the U.S. date.

Krevat from SDG&E noted that there are now cases in their service territory where energy is flowing from the substation and back into to transmission lines in areas with high rooftop solar penetration on very sunny days. This is worrisome for SDG&E, as they will need to pay for transmission and distribution (T&D) upgrades if the grid is to provide functions beyond the original purpose of providing power in one direction. How will this affect customers? Krevat is worried that the customers with rooftop solar are saving on their energy bills, while the lower income customers without rooftop solar will see increased bills as regulated (and decoupled) utilities need to pass distribution upgrade costs onto their entire customer base.

Miller of SunRun came with talking points pre-prepared. He’s worked for the Department of Energy. He’s worked for big utilities, like Exelon and Constellation Energy. He called the utilities out for deliberately blocking solar’s progress with arguments like this:

Utilities are by far the biggest obstacle. Utility lobbyists out in the trenches against solar. It is against their business model. It’s written in legislative and regulatory proceedings… When distributed generation is high, they will sell less power on their wires, so their objective is to push rates as high as possible.

Krevat contended that indeed it was a ratemaking issue. They can’t put the growing cost of distribution upgrades on a diminishing number of lower income customer. A different rate model might be needed. Haskell of Pecan Street chimed in:

Our observation is that utilities need to move away from charging for kilowatt hours and towards charging for quality of service. Grid connection fees for distributed generation, the amount of reliability the customer desires (# of 9’s), and the cost of putting energy back on the grid.

Now this sounds like an environment for commercial-scale microgrids, but it would be interesting to see how such a model might work for residential customers. Miller continued to provide the talking points for a distributed solar future:

Things are working in California because there are good legislators and regulators who believe in a distributed generation vision. The governor has a 12 gigawatt DG goal. Hawaii is a sneak peek into the future. 5% of homes and 3% of power is now from solar. The transformers haven’t blown up and the lights haven’t gone out.

He backed up his points with a white paper produced by Vote Solar and Crossborder Energy that found that even lower income ratepayers will benefit from higher amounts of net metering. Yes, the utilities have to pay for some additional distribution infrastructure upgrades, but the benefits (power delivery savings, lower cost of meeting renewable targets, avoided transmission upgrades, reduced electricity losses, etc.) will outweigh those costs by $92 million in California.

Keystone: activists build a movement while wonks say ‘carbon tax’

2013 March 13

P1140885

After I published this piece, two future classmates from the Goldman School of Public Policy responded with their thoughts on Keystone (the skeptic, anti-Keystone)

When the final decision is made on Keystone XL this summer, activists are hoping that President Obama will put it in the grave for good. After Obama’s soaring promises on climate change in his second inaugural and state of the union addresses, activists are expecting him to walk the talk and reject it. The latest rallies against the pipeline on February 17, which numbered over 50,000 in Washington, DC and over 5,000 in San Francisco, have continued to bring attention to the pipeline and put continued pressure on Obama. Meanwhile, policy wonks and editorial boards say that the anti-Keystone movement is wasting its energy on the wrong fights. They say the movement should focus on a carbon tax, and that the tar sands will be developed regardless of the decision on Keystone XL. Grist’s David Roberts nicely highlighted why the wonks are talking right past the activists: activism and policy are not the same thing.

About a year back, I heard Bill McKibben of 350.org speak in Berkeley and asked him: “What policy proposal does 350.org focus on in Washington?” McKibben politely answered what may have been a dumb question. He said, “350.org’s sole focus is to build a political movement that demands action on climate change now.” He mentioned his interest in good policy proposals, but it is just not his organization’s focus. For someone who has clearly spent too much time in DC (ahem, one year), this was somehow an a-ha moment for me. It’s not about policy A vs. policy B. It’s not about lobbying to pass one big climate policy. It’s about creating a movement that will continue to demand laws, actions, and leaders on climate change no matter what the prevailing political winds or policy proposals are. Even if we do pass a carbon tax or cap and trade bill, that will be just the first battle in a very long fight against climate change.

Right now, a Keystone rejection would symbolize a win for the movement and validate that Obama can be swayed into action by the powerful group of voices that have spoken. And to be fair, the pipeline has so little going for it. Fellow BERCie Reid Spolek asked my 140-character opinion on the project, and I replied on twitter: “With few jobs, no U.S. energy security benefit, & climate consequences, why would Obama pass it? To protect business interests.” At least that’s what Obama’s golf round with oil execs on the day of the latest rallies indicated.

Jobs: The pipeline would create a couple thousand temporary construction jobs, but reportedly only 35 permanent jobs. Energy security: The tar sands shipped to Louisiana for refining would be sold on global markets with no apparent direct benefit to U.S. energy security (so please don’t try any gas price arguments). Climate: Refining and burning tar sands causes 17% more emissions than regular crude, and building this pipeline locks in their development. If you read the thousands of pages of environmental assessment prepared to date by the State Department, you would probably be left scratching your head as to why anyone would approve this pipeline (State makes no firm recommendation for or against the pipeline). Let’s hope that this summer, Obama doesn’t leave us all scratching our heads.

Crystal Ball: China will not produce more wind energy than the U.S. before 2020

2013 February 27
by susty

This is a cross post from Green Leap Forward

Taken in 2009 at a wind farm near Keshiketengqi, Chifeng, Inner Mongolia

Taken in 2009 at a wind farm near Keshiketengqi, Chifeng, Inner Mongolia

Around this time last year, I blogged about some misconceptions on U.S. and China’s installed wind capacity and wind energy generation, highlighting that the U.S. was producing 64% more wind energy than China in 2011 with the same amount of turbines. I explained the reasons for this including China’s difficulties with their Renewable Energy Law, grid connection bottlenecks, and performance gaps due to technology and wind resource issues. In this blog, I’d like to provide a quick update on the U.S. and China wind energy development using newly released 2012 data, and then offer up a prediction for the rest of the decade.

2013-cap

Using data from China Electricity CouncilBloomberg New Energy Finance (BNEF), Global Wind Energy Council (GWEC), and the EIA, here are the key facts for wind development in 2012:

  • According to GWEC, the U.S. and China installed nearly the same amount of wind capacity in 2012 with 13.1 gigawatts (GW) and 13.2 GW, respectively. This was a record year for the U.S. (previous record was 10 GW in 2009).
  • Of that 13.1 GW installed in the U.S., 5.5 GW was installed in December alone, as project developers rushed to bring their assets online ahead of the expiration of the Production Tax Credit (PTC, which later ended up being extended).
  • China now has more grid connected wind capacity than the U.S. with 62 GW compared to the U.S.’s 60 GW, but the U.S. produced 40% more wind energy than China in 2012.
  • 83% of wind turbines (or 5 of 6) in China are grid connected now, compared with a low of 63% in 2009, providing evidence that China’s grid connection bottleneck is easing.
  • Wind accounted for 3.5% of total electricity generation in the U.S. in 2012, compared to 2.0% in China.

2013-gen

It seems that China is poised to overtake the U.S. in wind energy generation as well. Their year on year growth in installed capacity growth and generation is simply much higher than that of the U.S. Certainly, China has a more predictable development environment with its fixed feed-in tariff for wind, determined wind targets, and consolidated wind manufacturing base. China is expected to continue installing more than 15 GW in the coming three years.

Meanwhile, in the U.S., developers, manufacturers, and financiers alike experience a maddeningly uncertain development environment. To start, the PTC is well-known for its boom and bust cycles, and some say this trend is set to continue. Add to that the threat of low natural gas prices and the layoffs that diminish the political promises of green jobs. Despite these deep uncertainties, there are things to be optimistic about, and there are a number of reasons why I believe the U.S. will continue to produce more wind energy than China through 2020.

First, let me set up the case I am trying to defeat, depicted below, where China overtakes the U.S. in total wind energy generation in 2017. I’ve set up an optimistic case for China and a pessimistic case for the U.S. For China, there will be 16-17 GW of installations a year, as average capacity factors and the proportion of grid connected wind farms both increase over time. For the U.S., there will be a very slow 2013 with only a few gigawatts installed followed by a stellar 2014 with 12 GW installed (the expiration and extension of the PTC will cause this unevenness), then installations will plateau to 8 GW per year (roughly the average seen from 2008-2012). Average capacity factors will stay steady as improved technology yields decent capacity factors for even lower class wind resources.

2013 scenarios

In reality, I should be more pessimistic for China and more optimistic for the U.S. Through 2020, China will definitely see large amounts of installations and increased grid connection rates. However, poor wind resources, grid integration issues, and contractual violations (see discussion on PPA’s in last year’s blog) will keep average capacity factors low.

And perhaps it’s a bit of American pride in me, but I see significant upside for U.S. wind from 2015-2020. Wind equipment costs continue to fall. Shale gas drilling costs will increase, and natural gas prices will follow. Increasingly, utilities will want to buy wind power, not for RPS obligations, but for reasons of profit (as they already are doing). Offshore wind development will finally start appearing as Cape Wind finally comes to fruition and a mid-Atlantic offshore transmission backbone gets financed and built. Heck, even politicians might get their act together on tax reform and extend the PTC for a few years instead of just one. This time, they would be wise to add a sunset clause, whereby the wind industry is slowly eased off of subsidies for good. Any clean energy standard passed in the coming eight years will provide additional upside. Admittedly, this is a lot of optimism, but even if a number of these developments come true, I believe the U.S. will see 10 GW or more of installations per year out to 2020. The result: China will remain in second place and the U.S. will remain the world’s top wind energy generating country.

 

Post tsunami, Japan faces a whirlwind of energy policy decisions

2013 February 26

lng-tanker

Before the terrible tsunami and Fukushima Daiichi nuclear power plant disaster in March 2011, Japan produced 30% of its electricity from nuclear and had plans to increase it up to 50%. In the wake of the disaster, Japan shut down all but two of its reactors and sought to completely phase out nuclear power by 2040, according to the new energy plan that was released by the Democratic Party of Japan (DPJ) in September of last year.

Yet, the plan which was promoted by the DPJ was reportedly a “desperate election gambit” in the run up to December’s election – an attempt to cater to the anti-nuclear voting public. It was the Liberal Democratic Party’s Shinzo Abe who won the election to become Prime Minister, however, and he is in favor of turning the reactors back on.

This move speaks volumes of the power of the business lobby, which does not want to see increased power prices and would like to keep as much cheap nuclear power online as possible. Post Fukushima, electric utility giant Tepco is in an enormous amount of debt, and Japan is in a dangerous position in terms of energy security and costs. It has to import the large majority of its fuel, be it coal, natural gas, or oil. Bloomberg reported last November that Tepco would invite bids for 12.5 gigawatts of new coal fired power. UC Berkeley’s Richard Muller, author of Energy for Future Presidents, relayed to me the danger of such a move in a recent interview:

Switching to coal is terrible is many ways from the mining pollution to the coal ash pollution to the global warming issues. The dangers of coal are far worse than those of a nuclear reactor. And they would have to import the coal, too. They lose on the national security issue… It makes so much sense for Japan to turn its nuclear reactors back on, and that is what I believe Japan will do. They will do it quietly… They give the impression it’s only temporary, but I think the alternative of coal would be far, far worse.

Indeed, reliance on imported coal and natural gas will remain an expensive option, running up Japan’s trade deficit while continued consumption cuts hurt its recovering economy.

One promising alternative is renewable energy, namely solar and offshore wind. The world’s largest offshore wind farm may be built off the coast of Fukushima. Japan’s new feed-in tariff scheme for wind and solar could see a cumulative 20 gigawatts of wind and solar capacity by 2014, according to Bloomberg New Energy Finance. While Japan benefits as a “latecomer” in solar PV deployment with prices having fallen precipitously in recent years, a significant penetration of offshore wind and solar will still be a costly option. Turning on idle nuclear units in the short-term may buy some time for further cost reductions and technological advances in the renewables arena.

As the world’s third largest economy and an island nation, Japan is certainly providing an intensified test-bed for the energy policy decisions many countries will face as energy security and climate change become center stage issues.
