Laying the Foundation for Renewable Energy Certification Programs in Asia
At Google, we’ve made a
long term commitment
to power 100% of our operations with renewable energy. To that end, we’ve
purchased more than 2 gigawatts of renewable energy
to date, making us the world’s largest non-utility purchaser of renewables.
– including our facilities in
that help us provide people in Asia with faster, more reliable access to our tools and services – make up the majority of our electricity consumption. We are
working to power all of our data centers around the world with renewable energy
, but one of the challenges we face in Asia is that effective renewable energy certification programs simply aren’t available.
To help address this, we’re announcing today that we’re providing seed funding to the
Center for Resource Solutions
(CRS) to begin laying the groundwork to establish such programs across Asia, starting in Taiwan. They have over 20 years of experience developing and operating renewable energy certification programs.
These kinds of programs are key in helping companies like Google actually know that the power we are buying comes from a renewable source. They work by “tagging” each MWh of energy generated from a source like wind or solar as renewable, which creates a renewable energy certificate (“REC”). This is especially important to us in Taiwan, where we are actively looking to purchase renewable energy for our data center.
from CRS explains how this works for some customers. In Google’s case, we buy both the physical power and the RECs associated with that power, providing us with both the financial benefits of renewable energy and the assurance that the electricity we are buying is in fact renewable.
It may not sound like much, but these programs are critical to creating well-functioning voluntary renewable energy markets. For the
dozens of Fortune 100 and Global 100 companies that have renewable energy commitments
, RECs are a critical instrument to ensuring that renewable energy purchasing claims are accurate and verifiable. They have played a key role in enabling companies in the United States to grow their renewable energy purchasing from about 100 MW in 2012 to over
3,000 MW last year
With this support from Google, CRS will begin examining how best to structure these programs across Asia to create robust voluntary renewable energy markets. They will also begin building a coalition of international stakeholders from the public, private, and NGO sectors to drive these efforts forward.

Google unites with other tech companies to support US Clean Power Plan.
Today Google, along with Amazon, Apple and Microsoft, filed a legal brief with the DC Circuit Court supporting the
Environmental Protection Agency’s Clean Power Plan.
The CPP aims to accelerate the transition to cleaner sources of electricity and puts an emphasis on renewable energy development and energy efficiency. The plan has been put on hold pending the outcome of a legal challenge.
Google, Amazon, Apple and Microsoft have come together in
to offer our unique view as large consumers of energy. Collectively we used 10 million MWh of electricity last year, including at 50 data centers in 12 states. That means reliable and affordable electricity is integral to the continued growth and operation of all of our businesses and the services we offer to our users everywhere. We are all committed to sourcing our power in a sustainable way, and renewable energy makes good business sense for us all.
At Google, we have been
carbon neutral since 2007
. We have signed contracts to
purchase over 2GW of renewable energy
-- equivalent to taking nearly one million cars off the road -- making us the largest non-utility renewable energy purchaser in the world. Just last year we signed the
largest and most diverse purchase of renewable energy
made by a non-utility company to power our data centers. The deal covers a series of new wind and solar projects around the world and takes us one step closer to our goal of powering 100% of our operations with clean energy. Above and beyond our own power purchases, we have also invested
more than $2.5 billion in 22 other renewable projects
around the world.
These efforts underline the seriousness of our
commitment to renewables
and we believe the CPP is an important step in the transition to a cleaner energy future. The message from our companies today is clear -- we can meet the world’s future energy challenges in a way that drives innovation and growth while tackling climate change.

And the winner of the $1 Million Little Box Challenge is…CE+T Power’s Red Electrical Devils
In July 2014, Google and the
launched the $1 Million
Little Box Challenge
, an open competition to design and build a small kW-scale inverter with a power density greater than 50 Watts per cubic inch while meeting a number of other specifications related to efficiency, electrical noise and thermal performance. Over 2,000 teams from across the world registered for the competition and more than 80 proposals qualified for review by
IEEE Power Electronics Society
and Google. In October 2015,
18 finalists were selected
to bring their inverters to the
National Renewable Energy Laboratory
(NREL) for testing.
Today, Google and the IEEE are proud to announce that the grand prize winner of the $1 Million Little Box Challenge is
’s Red Electrical Devils. The Red Electrical Devils (named after
Belgium’s national soccer team
) were declared the winner by a consensus of judges from Google, IEEE Power Electronics Society and NREL. Honorable mentions go to teams from
Virginia Tech’s Future Energy Electronics Center
[CE+T Power’s Red Electrical Devils receive $1 Million Little Box Challenge Prize]
Schneider, Virginia Tech and The Red Electrical Devils all built 2kW inverters that passed
100 hours of testing at NREL
, adhered to the technical specifications of the competition, and were recognized today in a ceremony at the
ARPA-E Energy Innovation Summit
in Washington, DC. Among the 3 finalists, the Red Electric Devils’ inverter had the highest power density and smallest volume.
Impressively, the winning team exceeded the power density goal for the competition by a factor of 3,
which is 10 times more compact than commercially available inverters!
When we initially brainstormed technical targets for the Little Box Challenge, some of us at Google didn’t think such audacious goals could be achieved. Three teams from around the world proved decisively that it could be done.
Our takeaway: Establish a worthy goal and smart people will exceed it!
Congratulations again to CE+T Power’s Red Electrical Devils, Schneider Electric and Virginia Tech’s Future Energy Electronics and sincere thanks to our collaborators at IEEE and NREL. The finalist’s technical approach documents will be posted on the
Little Box Challenge website
until December 31, 2017. We hope this helps advance the state of the art and innovation in kW-scale inverters.

Understanding Our Goal: What it Means to be Powered by 100% Renewable Energy
Big dreams lead to big steps and that couldn’t be more true at Google. We’ve made a commitment to power our operations with 100% renewable energy and to date we’ve made great strides towards that goal. Last month we announced
842 MW of new renewable energy purchases in the US, Sweden, and Chile
which boosts our overall purchasing to over 2 GW of renewable energy capacity. This has the same carbon impact as taking nearly 1 million cars off the road and helps us get closer to our 100% goal.
But what does it really mean to be 100% “powered by renewables”? Fundamentally we mean this:
Google purchases, on an annual basis, the same volume (MWh) of renewable energy as the volume of MWh of energy that we consume for our operations.
To unpack what this means let’s start with some basics of the electricity system itself.
We know that electricity generated in one spot cannot be physically directed to a specific user over the electricity grid any more than a cup of water dumped into a river could be directed to a particular runoff stream. Once you put electricity on the grid, it becomes part of the pool of energy within that grid system and flows where physics dictates. There is no way to track if “the energy from wind farm X is going to supply data center Y.”
Given that you can’t tell electrons where to go, how do you “use” renewable energy? One solution is to not use the grid at all, for example by installing renewable generation adjacent to a power-consuming facility “behind the meter”. But this doesn’t usually make economic or practical sense for large facilities like data centers. Instead, large renewable energy projects should be developed where they are most productive and cost-effective - which is usually miles away from where our data centers are best located.
Further, wind and solar resources provide power only when the wind is blowing or the sun is shining but Google’s data centers operate 24x7. If we wanted to power our data centers from adjacently-sited wind or solar and operate disconnected from the rest of the grid, Google’s products would be offline whenever renewable resources aren’t producing energy. Grid-scale energy storage resources (for example very, very large batteries) could solve this problem, but storage technology at the scale we would need is far from cost-effective today.
Figure 1: Indicative hourly profiles for energy consumption from a data center and energy production from wind and solar resources. Note that these are profiles are purely indicative and do not represent specific data center or renewable generation facilities.
As we move towards a 24/7 zero-carbon electricity world we will need to remain connected to the electric grid to allow people to access their Gmail when they want, upload YouTube videos at all hours of the day, and collaborate on docs and spreadsheets with colleagues on the other side of the world.
Indeed, there are tangible benefits to using the grid, such as helping to manage the variability of renewables. For example, our Iowa utility, MidAmerican Energy, has a portfolio of energy generation that is comprised of 40% wind and takes advantage of a large regional network to manage any variability in its system or in an individual wind resource. Similarly, in Europe, the energy provider for our Finland data center purchases renewable energy in Sweden and uses the Nordpool regional electricity grid to manage variability and deliver us consistent 24x7 power.
These are the criteria we strive to meet whenever we purchase renewable energy:
We want our efforts to result in new renewable energy projects, not reshuffling the output from existing projects. For example,
Google committing to buy the entire output of a 72 MW wind farm in Northern Sweden
provided enough revenue security to wind developer O2 to be able to secure financing from German insurance firm Allianz to construct the project. This arrangement brought additional renewable energy onto the grid as a direct result of Google’s long-term commitment.
Bundled physical energy and its “renewable certification”.
We purchase both the physical renewable power and the corresponding certification of its renewable source -
in the United States and
in Europe - which represents the “green-ness” of the power (a detailed explanation of this is
). Many companies simply buy RECs or GOOs from existing projects on the open market, unbundled from the physical power. We set a high bar at Google and always seek to purchase these together.
Where possible we look for renewable projects close to where our data centers are based to maximize physical proximity of renewable supply and consumption. For example we purchase all wind energy generated by
NextEra Energy Resources’ 100.8 MW Minco II facility in Oklahoma
, which is within the same grid area as our
data center in Pryor, Oklahoma.
As we grow we may find ourselves temporarily oversupplied in some regions and undersupplied in others (where access to renewables is currently more limited). We will also be drawing power from the grid to meet our 24/7 power supply needs, which means being dependent on the local grid mix even if portions of it are non-renewable -- although as explained above, we will have separately purchased enough MWh of renewable generation to “cover” this non-renewable portion.
Over the long term, we know that to be serious about solving climate change and reaching 100% renewable, we will need to do more. To that end we are supporting policy and market reforms including
effective design and rollout of the Clean Power Plan
creation of pan-European electricity grids
, working on new technologies like
, and conducting
in-depth research on data center design to maximize energy efficiency.
And we’re looking for opportunities to repurpose traditional electricity infrastructure as we did with our
renewable-powered data center on the site of a former coal plant in Alabama
Here’s to dreaming big!

Welcoming Internet Engine No. 15
Data centers are the engines of the Internet. As the next billion users come online—whether making payments from a mobile phone in Nairobi or
at Broad Institute in Boston—we need to increase our capacity to serve them, and keep things running blazing fast.
Today we’re announcing what will become our 15th global data center—we’re thrilled to be named new owners of the former Hemlock Semiconductor site in Montgomery County, Tennessee.
When selecting any site, we look at the unique attributes and base our designs around them to build the most efficient and high-performing data centers possible. For example, our newest data center
in Alabama, U.S.
will be built on the site of a coal power plant, and in
we built on an old paper mill and use seawater as the sole cooling mechanism.
The Hemlock site was originally developed as a Semiconductor manufacturing plant, but unfortunately was never completed. We’ll be able to re-use much of the existing infrastructure, and will recycle and re-design what we don’t. Based on our assessments, this site will be able to house new technologies we’re currently testing in research & development, which would make this data center the most technologically advanced in the world.
We are excited to again be working with the Tennessee Valley Authority (TVA), who will be our electricity provider at this site. Thanks to an arrangement with TVA we’ll be able to scout new renewable energy projects and work with them to bring that power onto their electrical grid; another step toward Google’s ultimate goal of being powered by 100% renewable energy. As the largest corporate energy purchaser in the world,
we have signed 2 gigawatts of renewable energy supply contracts
to offset the power used across our portfolio of data centers—equivalent to taking nearly 1 million cars off the road.
It’s a real pleasure to be moving into this space, and to become a part of Montgomery County. Total investments in this project will amount to more than $600 million, and we’ll start engaging with city and county officials to launch a formal community grants program around three issues: science and technology education, clean energy, and access to the Internet.
While opening a data center can take years, we can’t wait to get to the drawing board to design the next internet engine in our lineup. Good things come to those who wait!

Notes from COP21
From November 30 through December 11, the French government hosted
the UN Climate Change Conference which resulted in 195 countries coming together to adopt the most ambitious climate change agreement in history. Roughly 40,000 people attended including 195 nations and thousands of NGOs and corporations.
Over the past two weeks in Paris, Googlers have been discussing how sustainability has been making good business sense for us. We believe that strong action from the business community is critical to meeting the climate challenge. We were official sponsors of COP21 through the French Government, we co-hosted an event with RE100 and The Climate Group on the role of industry in driving renewable energy growth, and we showcased a Google immersive
with rolling presentations of climate content from various partners!
At our event with
The Climate Group
, we hosted leaders from government and business at our Paris office to discuss the role that companies can play in leading the way to a 100% renewable energy future. More than 60% of global Fortune 100 companies have set public renewable energy or GHG reduction targets not only because they believe in environmental sustainability but because they think that renewable energy makes good business sense. Leaders from Google, Ikea, Unilever, Marks & Spencer, and Philips Lighting
discussed their business cases
for purchasing renewable energy, and were joined by officials from the European Commission and the South Australian Government to focus on the role of government policy in unlocking private sector demand for renewables.
To help showcase climate issues, the “Google Portal,” an immersive 9 screen, 3 x 3 meter square interactive display, was constructed in the public Climate Generations Area to allow people to explore and learn about their world, and to encourage public discussion. With 70 presentations, nonprofit demonstrations ranged from sea level rise by
, deforestation from
Global Forest Watch
from Underwater Earth and Sylvia Earle, and
on the current state of climate changes. The Mayor of Paris, along with a
broader coalition of mayors
, presented their climate commitments before formal submission to the United Nations. The UN Food and Agriculture Organization discussed
and land classification tool to enable country reporting and measurement and the EU Commission previewed the first look at a Global Water Surface map over the last 30 years. Google projects including
energy kites, the
Earth Engine platform
of the changing landscape, and YouTube’s
campaign were shown.
It's great to see a strong international climate agreement coming out of Paris that moves us towards a zero-carbon economy. Climate change is one of the most significant global challenges of our time. Rising to that challenge involves a complex mix of policy, technology, and international cooperation and Google is committed to doing our part.

Should you go solar? Just ask Project Sunroof.
COP21 conference in Paris
comes to an end this week, we’re expanding
, our online tool to help homeowners explore whether they should consider installing solar panels to reduce their energy costs, which we
in August. Starting this week, millions of homeowners across
select metro areas
in the most active solar states in the U.S., including California, Massachusetts, Arizona, New York, New Jersey, Nevada, Connecticut, Colorado and North Carolina, will be able to calculate their roof’s solar energy potential by using the same high-resolution aerial mapping technology used in Google Earth. Having this information will give you information on how to increase energy efficiency while cutting your monthly electric bill.
To provide accurate estimates,
uses a unique set of data that assesses how much sunlight your roof gets, the orientation, shade from trees and nearby buildings, and local weather patterns—essentially creating a solar score for every rooftop that it maps. You can then provide your current average electricity costs and compare them to what you'd pay with solar. So not only can you learn whether your house is a good fit for solar panels, but you can also determine whether paying for installation will pay off in the long run -- in short, see the effect sunlight can have on your wallet.
Map of sunlight hitting roofs in downtown Boston
Solar installations today are growing rapidly (a system is installed every
in the U.S.), but there remains tremendous untapped potential. In fact, only half a percent of U.S. electricity comes from solar power. According to GTM Research and the Solar Energy Industries Association’s
U.S. Solar Market Insight Report
, the US is on track for a record-breaking year, thanks to a booming residential photovoltaics market. By end of 2016, cumulative solar installations are poised to nearly double.
Solar may help you cut costs while increasing efficiency. With
, you can more easily assess your home's solar energy potential—and help move us all toward a more renewable future.
