Is your house haunted by high energy prices?
10/21/08
Halloween is nearly upon us; the days are getting shorter and Google is gearing up for one of our favorite holidays. But as the temperature drops, the price you pay each month to power your home might start to make your blood run cold. Fear not! We've created a handy
energy saving calculator
to help you see how simple steps can help you save money for treats -- and ward off scary carbon emissions. We've also put together a
webpage full of tricks
to help you save energy -- and money. (For inspiration for this idea, we want to thank the U.S. Department of Energy.)
It's the perfect time of year to talk about efficiency since many of the energy-wasters in our homes are named after the ghouls of Halloween. Our living rooms may be infested with "vampire" electronics that suck power even when turned off. And open chimney flues let the "ghosts" of winter steal our heat (not to mention the "monster" furnace that lives in the basement). By taking small steps to ward off these ghouls of inefficiency, you can save cold, hard cash. By
one estimate
, if the 80% of Americans who leave their fireplace flue open all winter all simply closed the damper, we could save over $6 billion a year. That's a lot of candy corn!

Supporting U.S.-Chinese renewable energy collaboration
10/20/08
Google.org has given the
U.S. National Academies
a grant for $250,000 to develop recommendations for U.S.-Chinese cooperation on renewable electricity. The 18-month study is being funded in collaboration with other U.S. sponsors and the Chinese Academies of Sciences and Engineering.
The study has three goals:
Assess the resource potential in China and the U.S. for grid-scale electricity generation
Explore near-term market opportunities for mature technologies
Recommend priorities for enhanced collaboration, with a focus on cost reduction, improved efficiency and grid connectivity, and storage
The study will help national governments, their relevant agencies/ministries, and private industries assign priorities for meaningful cooperation in developing and utilizing electricity from renewable energy.
By focusing on grid-scale electricity generation, the study will give special attention to three major resources: wind, solar, and biomass. It will also consider technologies with longer time horizons, such as
enhanced geothermal systems (EGS)
. It will build on a current U.S. National Academies study, which is assessing the technology risks and tradeoffs for various energy technologies. An understanding of the geographic, technical, and economic constraints will help guide Chinese decision makers to develop appropriate strategies to sustainably meet their energy needs. China’s manufacturing prowess, combined with its growing domestic market, provide opportunities to accelerate progress and reduce costs for renewable energy technologies.
The U.S. and China represent the world's two largest consumers of energy. Getting renewable electricity right for both countries will be a significant step to decelerating global climate change.

Clean Energy 2030
10/1/08
(Cross-posted from the
Official Google Blog
)
Right now the U.S. has a very real opportunity to transform our economy from one running on fossil fuels to one largely based on clean energy. We are developing the technologies and know-how to accomplish this. We can build whole new industries and create millions of new jobs. We can reduce energy costs, both at the gas pump and at home. We can improve our national security. And we can put a big dent in climate change. With strong leadership we could be moving forward on an aggressive but realistic timeline and an approach that balances costs with real economic gains.
The energy team at Google has been crunching the numbers to see how we could greatly reduce fossil fuel use by 2030.
Our analysis
, led by Jeffery Greenblatt, suggests a potential path to weaning the U.S. off of coal and oil for electricity generation by 2030 (with some remaining use of natural gas as well as nuclear), and cutting oil use for cars by 40%. Al Gore has
issued a challenge
that is even more ambitious, getting us to carbon-free electricity even sooner. We hope the American public pushes our leaders to embrace it. T. Boone Pickens has weighed in with an interesting
plan
of his own to massively deploy wind energy, among other things. Other plans have also been developed in recent years that merit attention.
Our goal in presenting this first iteration of the
Clean Energy 2030 proposal
is to stimulate debate and we invite you to take a look and comment - or offer an alternative approach if you disagree. With a new Administration and Congress - and multiple energy-related imperatives - this is an opportune, perhaps unprecedented, moment to move from plan to action.
Over 22 years this plan could generate billions of dollars in savings and help create millions of green jobs. Many of these high quality, good-paying jobs will be in today's coal and oil producing states.
To get there we need immediate action on three fronts:
(1) Reduce demand by doing more with less
We should start with the low-hanging fruit by reducing energy demand through energy efficiency -- adopting technologies and practices that allow us to do more with less. At Google, we've seen the benefits of this approach. We identified $5M in building efficiency investments with a 2.5 year payback. We've also
designed our own data centers to run more efficiently
, and we believe they are the most efficient in the world. On a smaller scale, personal computers can also become much more efficient. A typical desktop PC wastes nearly half the power it consumes. Last year, Bill Weihl, our Green Energy Czar, worked with industry partners to create the
Climate Savers Computing Initiative
to raise energy efficiency standards for personal computers and servers. If we meet our goals, these standards will cut energy consumption by the equivalent of 10-20 coal-fired power plants by 2010.
Government can have a big impact on achieving greater efficiency. California's aggressive building codes, efficiency standards and utility programs have helped the state keep per-capita energy use flat for years, while consumption in much of the rest of the country has grown significantly. Enacting similar policies at the national level would help even more.
We also need to give the American people opportunities to be more efficient. The way we buy electricity today is like going to a store without seeing prices: we pick what we want, and receive an unintelligible bill at the end of the month. When homes are equipped with smart meters and real-time pricing, research shows that energy use typically drops. Google is looking at ways that we can use our information technology and our reach to help increase awareness and bring better, real-time information to consumers.
(2) Develop renewable energy that is cheaper than coal (RE<C)
Google’s data centers draw from a U.S. electricity grid that relies on coal for 50% of its power. We want to help catalyze the development of renewable energy that is price competitive with coal. At least three technologies show tremendous promise: wind, solar thermal, and advanced geothermal. Each of these is abundant and, when combined, could supply energy in virtually every region of the U.S.
This year
Google has invested
over $45 million in startup companies with breakthrough wind, solar and geothermal technologies through our Renewable Energy Cheaper than Coal (
RE<C
) initiative, but that is a drop when we need a flood. We need to unleash massive private investment in clean energy. The government can have a big impact here as well. We must dramatically increase federal R&D and enact measures supporting the rapid deployment and scaling of clean technologies such as long-term tax support and a national renewable energy standard. Tax credits for wind and solar have lapsed several times in the last 20 years, starving these nascent industries of the capital they need to truly enter the mainstream.
We also must work both sides of the
RE<C
equation. Progress will be accelerated when the price of carbon reflects its true costs to society. Putting a price on carbon through cap-and-trade or a carbon tax would help address this.
(3) Electrify transportation and re-invent our electric grid
Imagine driving a car that uses no gas and is less expensive to recharge than buying a latte. A "smart grid" allows you to charge when electricity is cheap, and maybe even make some money by selling unused power back to the grid when it's needed. Plug-in cars are on their way, with GM, Toyota and other manufacturers planning introductions in the next two years. At Google we have a small fleet of Toyota Prius and Ford Escape plug-in conversions, as a part of our RechargeIT program. The converted Prius plug-ins get over 90 MPG, and the Escapes close to 50 MPG. However to successfully put millions of plug-in cars on the road and and fuel them with green electricity, we need a smart grid that manages when we charge and how we're billed. A smart grid could also provide for the two-way flow of electricity, as well as large-scale integration of intermittent solar and wind energy. Much of the technology in our current electrical grid was developed in the 60s and is wasteful and not very smart. We are
partnering with GE
to help accelerate the development of the smart grid and support building new transmission lines to harness our nation's vast renewable energy resources.
We see a huge opportunity for the nation to confront our energy challenges. In the process we will stimulate investment, create jobs, empower consumers and, by the way, help address climate change.

Saving electricity one data center at a time
10/1/08
Hundreds of millions of users access our services through the web, and this traffic requires lots of computers. We strive to offer great Internet services while taking our energy use very seriously. That's why, nearly a decade ago, we started work to optimize the energy efficiency of our servers and later set out to build the most environmentally sustainable data centers possible. We now believe that Google-designed data centers are the most efficient in the world.
The graph below shows what we've achieved: our data centers use considerably less energy for the servers themselves, and much less energy for cooling, than a typical data center. We achieved this milestone by significantly reducing the amount of energy needed for the data center facility overhead. Specifically, Google-designed data centers use nearly five times less energy than conventional facilities to feed and cool the computers inside. Our engineers worked hard to optimize every element in the data center, from the chip to the cooling tower.
As a result, the energy used per Google search is minimal. In the time it takes to do a Google search, your own personal computer will use more energy than we will use to answer your query. To learn more about our 5-step approach to efficiency, please check out our new
website
about efficient data centers.
