Google attempts to produce renewable energy cheaper than coal

Search giant Google on Tuesday pledged to spend hundreds of millions of dollars to make renewable energy cheaper than coal.

The push to mitigate the effects of climate change through clean energy falls squarely into Google.org's missions to improve human health and alleviate poverty, said Larry Brilliant, the executive director of Google.org.

The effort, dubbed RE Technologies created by Google will likely be used by Google, whose data centers are voracious consumers of electricity. The company envisions either selling electricity from renewable sources or licensing technology on terms that would promote broad adoption, according to company founders Larry Page and Sergey Brin.

Its overarching goal is to produce 1 gigawatt of electricity from renewable sources--enough to power the city of San Francisco--faster than the current pace of green-technology development.

"The main crux of this is that we believe that you can do it cheaper than coal...and we want to make it happen now," said Page, Google's president of products. "Most people who are doing this now are trying to do it less expensive than people before, but they are not trying for that goal which will have a significant effect on the world."

Investments in other companies will be funded by Google's philanthropic arm, Google.org, which has about $2 billion worth of Google stock available to it.

In particular, Google will be investing in solar-thermal technology, wind power, and geothermal systems. Its target is to fall below the price of coal power generation, which can be as low as 2.5 cents per kilowatt-hour, said Bill Weihl, Google's green-energy czar.

Google said it's already working with eSolar, a solar-thermal company building systems for utilities to generate electricity from heat. It has invested in Makani Power, which is pursuing electricity generation by harnessing wind at high altitudes.

As part of the effort, Google will be hiring experts in the energy field. It expects to hire 20 to 30 people into its clean-energy division in the next year. More substantial investments will come as energy projects come online, Weihl said.

Although an ambitious plan, Google's impact on the clean-tech market segment in the near term is likely to be more psychological than financial, said Paul Clegg, a senior equity analyst who follows clean tech at Jefferies.

"Tens of millions of dollars is not a small number, obviously, but you're spreading that over things that a lot of other companies are attacking on an individual basis with more money going at it," Clegg said. "I think they'd have to invest a lot more money to get the next Manhattan Project going."

However, Google's initiative is significant in that it could indicate how corporations will start addressing their energy needs and climate change going forward, he said.
