At least Google cares as its philanthropic arm Google.org, announced $10.25 million in investments in a breakthrough energy technology called Enhanced Geothermal Systems (EGS).
EGS expands the potential of geothermal energy by orders of magnitude. The traditional geothermal approach relies on finding naturally occurring pockets of steam and hot water. The EGS process, by comparison, replicates these conditions by fracturing hot rock, circulating water through the system, and using the resulting steam to produce electricity in a conventional turbine.
Google’s Renewable Energy Cheaper than Coal initiative focuses on solar thermal power, advanced wind, EGS and other potential breakthrough technologies. Google has set a goal to produce one gigawatt of renewable energy capacity, enough to power a city the size of San Francisco, in years, not decades.
“EGS could be the ‘killer app’ of the energy world. It has the potential to deliver vast quantities of power 24/7 and be captured nearly anywhere on the planet. And it would be a perfect complement to intermittent sources like solar and wind,” said Dan Reicher, Director of Climate and Energy Initiatives for Google.org.
