Gone fishin’—piloting community supported fisheries at Google

(Cross-posted on the Google Green Blog)

I've always loved the ocean—I was born in Shanghai, which means "upon the sea.” And as a chef, I'm always drawn to food that claims a spirit of place. After moving to California, near Half Moon Bay, I began visiting the docks to buy seafood, and got to know the fishermen.

Over time, it became evident to me that this part of our food supply is broken: many consumers purchase stale, unsustainably-raised fish from chain grocers. Meanwhile, fishermen often sell their diminishing catch to wholesalers at a very low profit, meaning their livelihoods are no longer sustained by their catch. There’s also the environmental factor to consider: Overfishing and illegal practices cause worldwide decline in ocean wildlife populations and wreak havoc on underwater habitats—not to mention the carbon footprint of transporting seafood far from its origin.

Google’s chefs have long been committed to sourcing food for our cafes as locally, seasonally and organically as possible. And in our Mountain View headquarters, many employees cook with the same ingredients at home thanks to on-site Community Supported Agriculture (CSA) programs. When I joined the team as an executive chef in Mountain View, I wanted to make a difference in our purchasing program for seafood. For the five years leading up to then, I wrote a column for the San Francisco Chronicle called “Seafood by the Season,” and I knew it could be done. In early 2010, we began a push to apply the most rigorous standards to our seafood-buying practices, and respond to the in-the-moment fluctuations of the catch from small, independent fishermen.

Things took off from there. My colleague Quentin Topping dreamed of providing the same high-quality seafood we serve in our cafes for Googlers to take home to their families. That idea became the Google Community Supported Fishery (CSF), which we launched in May 2011. In this program, Googlers sign up to purchase a weekly supply of local, sustainable seafood, supplied through a partnership with the Half Moon Bay (HMB) Fisherman’s Association.

We tend to think on a massive scale at Google—whether it’s how to deliver instant search results around the globe or help thousands of small businesses get online—but when it comes to feeding our employees at work and at home, it really comes down to a local touch. Knowing where our seafood, meat and produce come from, as well as knowing how they’re raised, farmed or harvested, makes all the difference in the on-the-ground work of sustainability. We see many bright spots ahead for our Community Supported Agriculture and Fishery programs, such as expansion to other offices and adding a grass-fed beef and pasture-raised poultry program. It’s exciting to work someplace where we can think big and local.

We know of two CSFs in the Bay Area. The Half Moon Bay Fishermen’s Association supplies only Google at the moment, but will soon add public drop-off sites—keep posted by visiting Farmigo.com. The other is CSea out of Bodega Bay. If you live elsewhere, we hope you’ll consider stepping up to create one in your area.

And even if you don’t live near the ocean or have direct access to fresh-caught seafood, the choices you make about what fish to purchase or order in restaurants can make a real difference. You may want to consider following the guidelines that we used for our Google Green Seafood policy: Whenever possible, purchase species caught locally and in-season, by small, independent fisher-families, using environmentally-responsible methods. We think it’s important to be responsive to the fluctuations of catch too, and source from fisheries that enforce catch limits or are guided by ecosystem-based management programs. As for us, we’ll continue to research and source responsibly managed farmed seafood, and always keep transparency and Googler health at the center of our program.

Examining the impact of clean energy innovation

At Google, we’re committed to using technology to solve one of the greatest challenges we face as a country: building a clean energy future. That’s why we’ve worked hard to be carbon neutral as a company, launched our renewable energy cheaper than coal initiative and have invested in several clean energy companies and projects around the world.

But what if we knew the value of innovation in clean energy technologies? How much could new technologies contribute to our economic growth, enhance our energy security or reduce greenhouse gas (GHG) emissions? Robust data can help us understand these important questions, and the role innovation in clean energy could play in addressing our future economic, security and climate challenges.

Through Google.org, our energy team set out to answer some of these questions. Using McKinsey’s Low Carbon Economics Tool (LCET), we assessed the long-term economic impacts for the U.S. assuming breakthroughs were made in several different clean energy technologies, like wind, geothermal and electric vehicles. McKinsey’s LCET is a neutral, analytic set of interlinked models that estimates the potential economic and technology implications of various policy and technology assumptions.

The analysis is based on a model and includes assumptions and conclusions that Google.org developed, so it isn’t a prediction of the future. We’ve decided to make the analysis and associated data available everywhere because we believe it could provide a new perspective on the economic value of public and private investment in energy innovation. Here are just some of the most compelling findings:

• Energy innovation pays off big: We compared “business as usual” (BAU) to scenarios with breakthroughs in clean energy technologies. On top of those, we layered a series of possible clean energy policies (more details in the report). We found that by 2030, when compared to BAU, breakthroughs could help the U.S.:
• Grow GDP by over $155 billion/year ($244 billion in our Clean Policy scenario)
• Create over 1.1 million new full-time jobs/year (1.9 million with Clean Policy)
• Reduce household energy costs by over $942/year ($995 with Clean Policy)
• Reduce U.S. oil consumption by over 1.1 billion barrels/year
• Reduce U.S. total carbon emissions by 13% in 2030 (21% with Clean Policy)
• Speed matters and delay is costly: Our model found a mere five year delay (2010-2015) in accelerating technology innovation led to $2.3-3.2 trillion in unrealized GDP, an aggregate 1.2-1.4 million net unrealized jobs and 8-28 more gigatons of potential GHG emissions by 2050.
• Policy and innovation can enhance each other: Combining clean energy policies with technological breakthroughs increased the economic, security and pollution benefits for either innovation or policy alone. Take GHG emissions: the model showed that combining policy and innovation led to 59% GHG reductions by 2050 (vs. 2005 levels), while maintaining economic growth.

This analysis assumed that breakthroughs in clean energy happened and that policies were put in place, and then tried to understand the impact. The data here allows us to imagine a world in which the U.S. captures the potential benefits of some clean energy technologies: economic growth, job generation and a reduction in harmful emissions. We haven’t developed the roadmap, and getting there will take the right mix of policies, sustained investment in technological innovation by public and private institutions and mobilization of the private sector’s entrepreneurial energies. We hope this analysis encourages further discussion and debate on these important issues.

An update on Google Health and Google PowerMeter

In the coming months, we’re going to retire two products that didn’t catch on the way we would have hoped, but did serve as influential models: Google Health (retiring January 1, 2012; data available for download through January 1, 2013) and Google PowerMeter (retiring September 16, 2011). Both were based on the idea that with more and better information, people can make smarter choices, whether in regard to managing personal health and wellness, or saving money and conserving energy at home. While they didn't scale as we had hoped, we believe they did highlight the importance of access to information in areas where it’s traditionally been difficult.

We’re making this announcement well in advance to give you plenty of time to download the information you might have stored in either product or to transfer it to another service, and we’re making it easy for you to do it in a variety of formats. More on how that works below.

More broadly, we remain committed as always to helping people around the world access and use information pertinent to them. We’ll continue to pursue this goal and to encourage government and industry to do the same.

Google Health
When we launched Google Health, our goal was to create a service that would give people access to their personal health and wellness information. We wanted to translate our successful consumer-centered approach from other domains to healthcare and have a real impact on the day-to-day health experiences of millions of our users.

Now, with a few years of experience, we’ve observed that Google Health is not having the broad impact that we hoped it would. There has been adoption among certain groups of users like tech-savvy patients and their caregivers, and more recently fitness and wellness enthusiasts. But we haven’t found a way to translate that limited usage into widespread adoption in the daily health routines of millions of people. That’s why we’ve made the difficult decision to discontinue the Google Health service. We’ll continue to operate the Google Health site as usual through January 1, 2012, and we’ll provide an ongoing way for people to download their health data for an additional year beyond that, through January 1, 2013. Any data that remains in Google Health after that point will be permanently deleted.

If you’re a Google Health user, we’ve made it easy for you to retrieve your data from Google Health any time before January 1, 2013. Just go to the site to download your information in any of several formats: you can print and save it, or transfer it to other services that support industry-standard data formats. Available formats include:

• Printable PDF including all the records in your Google Health profile
• Industry-standard Continuity of Care Record (CCR) XML that can be imported into other personal health tools such as Microsoft® HealthVault™
• Comma-separated value (CSV) files that can be imported into spreadsheets and database programs for ongoing tracking and graphing
• HTML and XML versions of the original “data notices” sent to your Google Health profile by linked data providers
• A unified ZIP archive that includes all files you’ve uploaded to your profile, plus all of the formats above

Over the coming weeks we’ll also be adding the ability to directly transfer your health data to other services that support the Direct Project protocol, an emerging open standard for efficient health data exchange. And while we’ll discontinue the Google Health service at the beginning of 2012, we’ll keep these download options available for one more year, through the start of 2013. This approach to download and transfer capability is part of Google’s strong commitment to data liberation principles: providing free and easy ways for users to maintain control of their data and move it out of Google’s services at any time.

In the end, while we weren’t able to create the impact we wanted with Google Health, we hope it has raised the visibility of the role of the empowered consumer in their own care. We continue to be strong believers in the role information plays in healthcare and in improving the way people manage their health, and we’re always working to improve our search quality for the millions of users who come to Google every day to get answers to their health and wellness queries.

Google PowerMeter
We first launched Google PowerMeter as a Google.org project to raise awareness about the importance of giving people access to data surrounding their energy usage. Studies show that having simple access to such information helps consumers reduce their energy use by up to 15%; of course, even broader access to this information could help reduce energy use worldwide.

Since our launch, there’s been more attention given to this notion of people easily accessing their energy data. The installation of smart meters and other home energy devices is picking up steam, and states like California and Texas are moving forward to finalize policies and programs in this area. Earlier this month, the White House announced a goal of giving all consumers access to their energy usage in computer-friendly formats as part of a national plan for modernizing the electricity grid.

We’re pleased that PowerMeter has helped demonstrate the importance of this access and created something of a model. However, our efforts have not scaled as quickly as we would like, so we are retiring the service. PowerMeter users will have access to the tool until September 16, 2011. We have made it easy for you to download your data: simply log in to your account and go to "Account Settings” to export to a CSV (Comma Separated Values) file. We will be contacting users directly with more information on this process.

Momentum is building toward making energy information more readily accessible, and it’s exciting to see others drive innovation and pursue opportunities in this important new market. We’re proud of what we’ve accomplished with PowerMeter and look forward to what will develop next in this space.

By helping people make more informed decisions through greater access to more information, we believe Google Health and PowerMeter have been trailblazers in their respective categories. Ultimately though, we want to satisfy the most pressing needs for the greatest number of people. In the case of these two products, our inability to scale has led us to focus our priorities elsewhere.

As always, we welcome your feedback; please share your thoughts and opinions with us at health-feedback@google.com or powermeter-feedback@google.com. We won’t be able to respond to every email, but we promise we’ll listen.

Update 7/15/11: We've now added the ability to directly transfer your health data out of Google Health via the Direct Project protocol.

Helping homeowners harness the sun

(Cross-posted from the Green Blog)

Imagine sitting on your patio watching the sun’s rays pass overhead, knowing that they power your home with clean energy—at a cost that’s less that what you would have paid using just the grid. That’s what my colleague, engineer Michael Flaster, has been doing at his home in Menlo Park, Calif. since March of this year. He did it with the help of a company called SolarCity, which enables homeowners and businesses to begin using solar energy to power their homes and buildings.

Today, we’re announcing that we’ve investing $280 million to create a fund that will help SolarCity finance more solar installations across the country. This is our largest clean energy project investment to date and brings our total invested in the clean energy sector to more than $680 million. We’ve also launched a partnership to offer SolarCity services to Googlers at a discount.



In SolarCity’s innovative financing model, the company covers installation and maintenance of the system over the life of the lease. You can prepay, or pay nothing upfront after which you make monthly solar lease payments. All told, Michael will save $100 per month on his energy bills this year, and more than $16,000 over his 15 year lease, after factoring in his lease payment and lower energy bills.

We believe the world needs a wide range of clean energy options in the future, each serving different needs. We’ve already invested in several large-scale renewable energy projects, so we’re excited that this new partnership with SolarCity helps people power their homes directly with solar energy, too. We think “distributed” renewable energy (generated and used right at home) is a smart way to use solar photovoltaic (PV) technology to improve our power system since it helps avoid or alleviate distribution constraints on the traditional electricity grid.

Our investment is a quadruple-win for Google, SolarCity, its new customers and the environment. We continue to look for other renewable energy investments that make business sense and help develop and deploy cleaner sources of energy. Whether harnessing the sun on rooftops like Michael’s or in the desert sands of the Mojave, it’s all part of building a clean energy future.

Leading the charge toward an electric vehicle fleet

(Cross-posted on the Green Blog)

Over the last few years, several innovative electric vehicle (EV) technologies have emerged in the marketplace and we’ve been working to update our green transportation infrastructure. As a result, we’ve now developed the largest corporate EV charging infrastructure in the country. We’re also including the next generation of plug-in vehicles in Gfleet, our car-sharing program for Googlers.

When Google.org launched the RechargeIt initiative in 2007, there were no commercially available plug-in hybrid EVs on the market. So we bought several Toyota Priuses and had them retrofitted with A123 Hymotion batteries to create our own mini-fleet of plug-in hybrids to demonstrate the technology. It was the birth of Gfleet, which has since become a valued perk and makes it easier for Googlers to use our biodiesel shuttle system to commute to work by providing green transportation options for people after they arrive at the Googleplex. The new Gfleet will include more than 30 plug-ins, starting with Chevrolet Volts and Nissan LEAFs, several of which have already arrived and are available for Googlers to use today. We’ll be adding models from other manufacturers as they become available.

To juice up our new cars and provide more charging options for Googlers, we’ve been working with Coulomb Technologies’ ChargePoint® Network to continue to expand our EV charging infrastructure. We’ve added 71 new and faster Level 2 chargers to the 150 Level 1 chargers we’ve installed over the last few years, bringing our total capacity to more than 200 chargers, with another 250 new ones on the way. The ChargePoint Network provides us the charging data necessary to track and report on the success of our green transportation initiative.

Overall, our goal is to electrify five percent of our parking spaces—all over campus and free of charge (pun intended) to Googlers. Our expanded charging system has already helped several Googlers decide to buy new EVs of their own, and we hope others will, too.



All told, Gfleet and our biodiesel shuttle system result in net annual savings of more than 5,400 tonnes of CO2. That’s like taking over 2,000 cars off the road, or avoiding 14 million vehicle miles every year! But we’re only one company, so we hope other companies think about how they can incorporate these new technologies into their own infrastructure. By supporting new, green transportation technologies, we’re enabling our employees to be green and doing our part to help spur growth in the industry.

Practical steps towards a greener, energy-efficient cloud

(Cross-posted from the European Public Policy Blog)

Update June 14, 9:14am: Videos of all the presentations at the Data Center Summit are now available on our website.

Data centers are very important to us—they’re critical to the cloud services we deliver. Over the last 12 years, we’ve put a lot of effort into minimizing the amount of energy, water and other resources we use—because it makes financial sense, and because it’s good for the environment too. That work means that today, we use half the energy of a typical industry data center.

Last week, we brought together more than 150 industry professionals in Zürich, Switzerland for our second conference on data center efficiency. Since our first conference two years ago in the U.S., the industry’s come a long way, with large operators now very focused on energy efficiency.



With “free cooling” we can dramatically reduce energy consumption by using the local environment to cool servers, instead of energy-intensive chillers. In our data centers we use both air cooling and evaporative cooling—and we revealed the details of the seawater cooling system we’ve custom-engineered for our new data center in Hamina, Finland.



Google is lucky enough to have the resources and experts to continually improve efficiency. But around 70% of the world’s data centers are operated by companies that probably don’t.

That’s why we shared five simple and low-cost steps that any company, large or small, can use. These include using plastic meat locker curtains to separate hot and cold air, or welding your own air-conditioning chimney out of cheap sheet metal. These techniques are proven to increase energy efficiency, reduce electricity consumption and improve environmental footprint.

We also announced that we’re now participating in the European Commission’s Code of Conduct for Data Centres, a framework for designing and operating data centers efficiently. It ties in closely with the way we build and run our facilities, and has a robust checklist of efficiency best practices that are well worth trying out.

The main take-away was that there is no magic in data center efficiency. With the right information and a bit of creativity, anyone can make their computing infrastructure efficient. If you operate a data center or server room, please visit our website and make use of the techniques we’ve outlined. Videos of all the presentations from the Summit will be available on the site next week.

Investing in the Alta Wind Energy Center

(Cross-posted from the Google Green Blog)

The Mojave Desert might be best known for its scorching sun and scary sidewinders, but the wind blows hard where the Mojave sands meet the Tehachapi Mountains in southern California, making it a great spot for wind turbines. It’s the site of the Alta Wind Energy Center (AWEC), which will generate 1,550 megawatts (MW) of energy when complete, making it one of the largest sites in the country for wind energy generation—enough to power 450,000 homes. Renewable energy developer Terra-Gen Power is constructing the site in several phases and we’ll provide $55 million to finance the 102 MW Alta IV project. Citibank, which has underwritten the equity for Alta Projects II-V, is also investing in this project.

We’re always looking for projects that are uniquely positioned to transform our energy sector. As part of the new 4,500 MW Tehachapi Renewable Transmission Project (TRTP), AWEC uses some of the first transmission lines developed specifically to transport renewable energy from remote, resource-rich areas (like the Mojave) to major population centers.

The Alta Wind Energy Center under construction

The Alta projects also employ an innovative financial structure called a leveraged lease, which has been used previously in the solar industry but has only recently become an option for wind projects. Under the leveraged lease, Google and Citi are purchasing the Alta IV project and will lease it back to Terra-Gen, who will manage and operate the wind projects under long-term agreements. We hope this structure encourages more investment by enabling other types of investors who might not typically consider wind projects.

The first five Alta projects are already operational, delivering 720 MW of energy to Southern California Edison, which will receive all 1,550 MW when completed, under a power purchase agreement signed with Terra-Gen in 2006. While Google won’t be purchasing the electricity from this project, AWEC will help California meet its ambitious renewable portfolio standard of 33 percent clean power by 2020. The whole site will boost California’s wind generation by 30 percent.

With this deal, we’ve now invested more than $400 million in the clean energy sector. We hope AWEC’s success, with its unique deal structure and renewable energy transmission, encourages more financing and development of renewables that will usher in a new energy future.

Update 6/22: Today, we’re increasing our investment in the Alta Wind Energy Center (AWEC) in Tehachapi, Calif. by providing another $102 million to finance the 168 MW Alta V Project. This adds to the $55 million investment we announced here last month for the 102 MW Alta IV project. We’ve now invested $157 million in 270 MW of clean, wind energy generation at AWEC. And that brings our total invested in this sector to more than $780 million, with over $700 million invested this year alone—all in projects that not only provide us strong financial returns, but also help to accelerate the deployment of over 1.7 GWs of clean renewable energy.

Celebrating Arbor Day with Save the Redwoods League and Google Earth

From time to time we invite guests to post about topics of interest and we’re pleased to have Emily Limm join us for U.S. Arbor Day. Emily is the science director for the non-profit Save the Redwoods League and is studying the impact of climate change on the redwood forests of northern California. To raise awareness about the League’s research, she worked with Google Earth Outreach to model old-growth redwoods on Google Earth. In this post, Emily shares her ideas on how technology and citizen science can help scientific research. -Ed.

Today is U.S. Arbor Day, a holiday established 120 years ago to celebrate our often under-appreciated forests, which provide us with necessities like clean air and drinking water as well as small pleasures like shade for a summer’s day picnic or a beautiful place to hike with crunchy leaves underfoot. Arbor Day holds special meaning for me because I spend most of my time in the coastal redwood forests of California, working to protect the world’s tallest tree species.

Over the past few months, Save the Redwoods League and the Google Earth Outreach team have collaborated to create 3D models of the old-growth redwood forest in Jedediah Smith Redwoods State Park in northern California, so you can now take a virtual hike among the ancient trees and cruise over towering treetops. Explore the park by activating the 3D trees layer in Earth (under 3D Buildings) and searching for [jedediah smith redwoods state park, ca]. Tilt your view angle toward the horizon to make the trees appear. You can download the KML file for the narrated tour about redwoods to view in Google Earth, or watch the video version below:



In order to protect redwoods in Jedediah Smith and elsewhere, my colleagues and I are working to collect data on geographic regions where the trees are currently thriving to determine how future forests will fare in our changing climate. A critical piece of our work is collecting and comparing field observations of redwoods across different climates, but we need more data to draw strong conclusions—and that’s where you come in.

Today, Save the Redwoods League is launching our citizen science project Redwood Watch, powered by iNaturalist.org, a platform for recording, organizing and mapping nature observations. By sharing a simple digital photograph of a redwood tree and the time and location where the picture was taken, you can help the League track and monitor the species. If you know of a redwood tree—perhaps in your own backyard or in a nearby park—you can use the free Redwood Watch iPhone application or your own camera to take a photo, add a comment and submit it online. iNaturalist stores your observation and, if geographical coordinates weren’t captured automatically, uses the Google Maps APIs to assign them to your photo. With your geolocated observation, we can zoom out and analyze your observation in the context of global environmental and climatic patterns.

An observation of a coast redwood submitted to the Redwood Watch on iNaturalist.org.

The more field observations Save the Redwoods League collects, the better we’ll understand what climate makes a healthy redwood today, and predict where the redwood forests of tomorrow will thrive. We hope to see you on the Redwood Watch.

Happy Arbor Day from Save the Redwoods League and Google Earth!

Note: There are plenty of parallel projects going on around the world, so if you don’t live near redwoods, consider participating in one of the other iNaturalist.org citizen science projects.

Celebrating Earth Day

Today, we’re celebrating Earth Day with an animated, interactive doodle on our homepage and events at Google offices around the world. At our headquarters in Mountain View, Calif., we’re holding an environmental fair for Googlers, complete with speakers and contests to strengthen Googlers’ green acumen, and a cookout using—what else—parabolic solar cookers (don’t worry, we’ll compost the leftovers).

Our campus garden in Mountain View

We’ve been carbon neutral since 2007 and—Earth Day or not—we’re always asking ourselves what we can do to make the world greener today than it was yesterday. This week, we launched a new website with many of the questions we’ve been asking over the years that have inspired our environmental initiatives. What can we do to make renewable energy cheaper than coal? How can we run a data center using 50 percent less energy? And what does it take to green our energy supply?

It’s questions like these that led us to install solar panels on our Mountain View campus in 2007—at the time, the largest corporate solar installation in the U.S. They’re also what made us decide to donate to Googlers’ favorite charities based on how often they self-power their commute, whether by bike or by pogo stick. We hope the new website helps you start asking bold questions that lead to innovative solutions to make the world a greener place.

In addition to our new site, we’ve had a busy few weeks continuing our green streak. We doubled down on greening our energy supply with our second power purchase agreement (PPA) in less than a year and made several new investments: at a solar photovoltaic plant in Germany (our first in Europe), and others in the largest wind farm and solar project in the world, bringing our total invested in clean energy to more than $350 million. While the investments won’t supply our operations with energy, we believe they make business sense and will spur development and deployment of compelling clean energy technologies.

This Earth Day, we’ll continue to ask ourselves what else we can do to bring us closer to true sustainability. We hope that you, and companies across the world, will be doing the same.

Oklahoma, where the wind comes sweepin’ down the plain

Rodgers and Hammerstein weren’t kidding when they wrote what is now Oklahoma’s official state song. The gusts on the plains are fierce, which makes the Sooner State a great place to harness clean, renewable wind energy. Our commitment to greening our energy supply is also strong, which is why we’ve just signed a power purchase agreement (PPA) for wind energy—our second in less than a year—in Oklahoma.

The purchase is similar in size and structure to the agreement we signed last July for wind energy in Iowa, but this time we will be applying the power to our Mayes County, Okla. data center, which will be fully operational later this year. We’ve agreed to purchase all of the energy from NextEra Energy Resources’ Minco II wind facility in Oklahoma for the next 20 years, through Google Energy LLC, an entity that enables us to participate in the wholesale energy market. This 100.8 megawatt facility will be built as a direct result of our financial commitment and should be operational in late 2011.



We’ve made the commitment to be a carbon neutral company, and this purchase is part of our effort to minimize our impact on the environment. We’ve managed to reduce our energy consumption by over 50 percent by building highly energy-efficient facilities, but we know that efficiency alone isn’t enough to eliminate our carbon footprint. We’ve been exploring ways, such as this PPA, to reduce emissions further by increasing the amount of renewable energy we use to power our operations; we purchase high-quality carbon offsets for any remaining emissions.

If you’re interested in learning more about the whys and wherefores of our renewable energy purchases, we’ve just published a white paper (PDF) on the topic. Our hope is that by laying out our reasoning and methods we’ll make it easier for others in the industry to explore similar arrangements.

These purchases represent long-term, meaningful actions to reduce our carbon footprint and power our operations with clean electricity. Our infrastructure team will continue to seek similar opportunities globally as Google’s businesses continue to grow. As a company we hope that purchases like these, plus the additional $350 million we’ve invested in renewable energy projects, support the market and drive down the cost of clean energy. This will enable even more companies to invest in sustainable energy solutions.

Shepherding the wind

We recently invested approximately $100 million in the Shepherds Flat Wind Farm, anticipated to be the largest wind farm in the world. Shepherds Flat is currently under construction near windy Arlington, Ore., and when completed in 2012 will produce 845 MW of energy. That’s a lot of wind—enough to power more than 235,000 homes.

This project is exciting to us not only because of its size and scale, but also because it uses advanced technology. This will be the first commercial wind farm in the U.S. to deploy, at scale, turbines that use permanent magnet generators—tech-speak for evolutionary turbine technology that will improve efficiency, reliability and grid connection capabilities. Though the technology has been installed outside the U.S., it’s an important, incremental step in lowering the cost of wind energy over the long term in the U.S.

Shepherds Flat will help Oregon continue to be one of the top wind producing states in the nation, while providing significant direct economic benefits to the state. The project will also benefit the region by helping California meet its aggressive renewable energy goals with a cost-effective and clean wind resource. The electricity produced at Shepherds Flat will be sold under long term agreements to Southern California Edison.

The Shepherds Flat Wind Farm under construction with me in the center and my colleagues Arielle Bertman and Matthew Stepka.

We look forward to joining a project with strong experienced partners such as the developer, Caithness Energy, and GE, which is an early investor in Shepherds Flat as well as the turbine manufacturer and operations and maintenance supplier. Our co-investors are Sumitomo Corporation of America, a subsidiary of Sumitomo Corporation, and Tyr Energy, a subsidiary of ITOCHU Corporation, both of which have deep experience in power projects.

This project brings our total invested in clean energy to more than $350 million, including our most recent investments in a German solar photovoltaic plant and in the BrightSource Ivanpah solar power tower—the largest solar energy project in the world. We’re excited about helping deliver clean energy to the grid and we hope this latest investment encourages other companies to think about ways they can help accelerate the deployment of more renewable energy. We remain on the lookout for more projects that make business sense and will help all of us take advantage of clean, renewable energy.

Investing in the world’s largest solar power tower plant

We’ve invested $168 million in an exciting new solar energy power plant being developed by BrightSource Energy in the Mojave Desert in California. Brightsource’s Ivanpah Solar Electric Generating System (ISEGS) will generate 392 gross MW of clean, solar energy. That’s the equivalent of taking more than 90,000 cars off the road over the lifetime of the plant, projected to be more than 25 years. The investment makes business sense and will help ensure that one of the world’s largest solar energy projects is completed.

We need smart capital to transform our energy sector and build a clean energy future. This is our largest investment to date, and we’ve now invested over $250 million in the clean energy sector. We’re excited about Ivanpah because our investment will help deploy a compelling solar energy technology that provides reliable clean energy, with the potential to significantly reduce costs on future projects.

Power towers, which have been successfully demonstrated in the U.S. and abroad at smaller scale, are based on a relatively simple idea. The technology works by using a field of mirrors, called heliostats, to concentrate the sun’s rays onto a solar receiver on top of a tower. The solar receiver generates steam, which then spins a traditional turbine and generator to make electricity. Power towers are very efficient because all those mirrors focus a tremendous amount of solar energy onto a small area to produce steam at high pressure and temperature (up to 1000 degrees F). Think about burning a tuft of grass with a magnifying glass, only multiplied by thousands (or the original application: Archimedes’ heat ray that allegedly used mirrors to burn enemy ships!).

Several large solar projects are in the works in the sunny Southwest (and around the globe), but Ivanpah will be the first solar power tower system of this scale. The Ivanpah Power Tower will be approximately 450 feet tall and will use 173,000 heliostats, each with two mirrors. The project is being constructed by Bechtel, a major engineering firm. Construction began in October 2010, and is projected to finish in 2013.

The Ivanpah project will also be financed by NRG and with clean energy technology loan guarantees provided by the U.S. Department of Energy. We hope that investing in Ivanpah spurs continued development and deployment of this promising technology while encouraging other companies to make similar investments in renewable energy.
