Technology can help us do more with less. For example, making use of natural climates has helped us make our data centers 50% more efficient than the industry average, and green building technology has helped us limit energy consumption in our offices around the world. Now, we’re doing more with less to power Google’s North Bayshore campus in Mountain View.

We’ve recently signed a long-term agreement to purchase enough local wind energy to offset the electrical consumption of our North Bayshore headquarters on an annual basis. While we’ve been committed to being a carbon-neutral company since 2007, and we purchase clean energy for our data centers, this agreement is the first of its kind when it comes to our offices.

The agreement with NextEra Energy Resources will help to repower an iconic Bay Area wind farm at California’s Altamont Pass with new turbines that will pour 43 MW of electricity onto the grid starting in 2016. This new technology is twice as efficient, and also safer—especially for wildlife.

The new turbines will generate energy that feeds into the grid that powers our North Bayshore buildings in Mountain View. While these electrons can’t be traced once they enter the grid, we can measure how many of them leave the turbines, as well as how many we use on campus on an annual basis (tracked through a system of renewable energy credits, or RECs). So even though the electrons follow an untraceable path through the California electricity grid, we can be sure that we're offsetting the electrical consumption of our North Bayshore headquarters with the renewable energy from the new turbines.

Since our first wind investment in 2010, we’ve developed close relationships with renewable energy providers, helping us secure renewable energy agreements like this one for our campus and data centers—more than 1.1 gigawatt’s worth to date—and it’s also made it possible for us to make equity investments in 17 utility-scale renewable energy projects. And over the years we’ve been thrilled to see other California leaders, from tech companies to universities, also working to bring more renewable energy online.

Finally, if we can geek out for a minute: We think this project is especially cool because back in the 1980’s, the golden hills of Altamont Pass were an early test bed for the first large-scale wind power technology in the U.S. We’ve been blown away (pun intended :)) by how far turbine technology has come since then. Once the installation is complete, and the 370 legacy turbines are replaced, it will take just 24 new ones to generate as much power as our campus uses in a year. Talk about doing more with less.

If you drive northwest from Des Moines, Iowa, you’ll see a lot of corn fields. From time to time, you’ll also see wind turbines rising out of those fields, making efficient use of our natural resources to produce renewable energy. It’s places like these that are home to a vibrant, emerging clean energy economy.

Today we‘re announcing that we’ve made an equity investment of $ 75 million in a 50MW wind farm in Rippey, a small town in Greene County, about an hour outside of Des Moines. The Rippey project, developed by RPM Access, is expected to produce enough energy to power over 15,000 Iowa homes. The project, which is now in operation, uses turbines produced by Nordex USA at their Jonesboro, Ark. facility.

We’ve taken two approaches to greening the grid in Iowa, a state where we operate a data center. Back in 2010, we entered into a long-term contract to purchase wind energy from NextEra Energy Resources’ Story County II wind farm. This time, we’re investing directly into a wind project, which has been contracted to sell all of the energy to the Central Iowa Power Cooperative, an Iowa-based utility that will deliver the energy to local consumers. We’re happy to help make more renewable energy available to Iowans and to support the growing wind energy industry in the state.

This project brings our committed investment to the renewable energy sector to more than $ 990 million. Read more about our previous investments on our Google Green site.

We announced our commitment to carbon neutrality back in 2007, and since then we’ve been finding ways to power our operations with as much renewable energy as possible. In our latest step toward this end, we just signed an agreement with the Grand River Dam Authority (GRDA) to green the energy supply to our Oklahoma data center with 48 MW of wind energy from the Canadian Hills Wind Project in Oklahoma, which is expected to come online later this year.

We’ve been working with GRDA, our local utility, to procure additional renewable energy since we “plugged in” our data center in 2011, and in February of 2012, GRDA approached us about purchasing power from Canadian Hills. In conjunction with the electricity GRDA already supplies Google to operate its data center, Google will pay GRDA a premium to purchase renewable energy generated by Canadian Hills. This brings the total amount of renewable energy for which Google has contracted to over 260 MW.

This agreement is a milestone for GRDA because it’s their first-ever wind energy project. It’s also a milestone for Google because it’s a little different from the previous Power Purchase Agreements (PPAs) we’ve signed, where we agreed to buy the energy directly from the developer who built the wind farm. This agreement, by contrast, marks the first time we’ve partnered with a utility provider to increase the amount of renewable energy powering one of our data centers.

Although both options can make sense depending on the circumstances, we’re excited about this collaboration because it makes the most of our respective strengths: utilities like GRDA are best positioned to integrate renewable energy into their generation mix and to deliver power; we’re a growing company with a corporate mandate to use clean energy for our operations in a scalable way. We’ve been working closely with all of our utility partners to find ways to source renewables directly, and we look forward to working with other suppliers to deliver clean energy to our data centers.

We’ve made a new $ 94 million investment in a portfolio of four solar photovoltaic (PV) projects being built by Recurrent Energy near Sacramento, California. This brings our portfolio of clean energy investments to more than $ 915 million. We’ve already committed to providing funding this year to help more than 10,000 homeowners install solar PV panels on their rooftops. But this investment represents our first investment in the U.S. in larger scale solar PV power plants that generate energy for the grid—instead of on individual rooftops. These projects have a total capacity of 88 MW, equivalent to the electricity consumed by more than 13,000 homes.

We’re investing alongside global investment firm KKR and Recurrent Energy, a leading solar developer. Google will provide a $ 94 million equity investment and SunTap Energy, a new venture formed today by KKR to invest in solar projects in the U.S., will provide the remaining equity.

We’re joining KKR on their first renewable energy investment in the U.S. We believe investing in the renewable energy sector makes business sense and hope clean energy projects continue to attract new sources of capital to help the world move towards a more sustainable energy future.

The energy produced by these projects is already contracted for 20 years with the Sacramento Municipal Utility District (SMUD). SMUD recently created a feed-in tariff program (FIT) to help green the grid for Sacramento-area residents. We’re excited that these projects are the first to be built under the program.

We’ve had a busy year at Google. Since January, we’ve invested more than $ 880 million in clean energy projects. We believe the world needs a wide range of solutions—from wind, to transmission, to solar PV and concentrated solar—and we look forward to new opportunities next year to further expand our portfolio of clean energy investments.

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.

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 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.
