GREEN RANKING FOR 2009
Ranking: 10=
Worth: £7.5bn
Green investment: Green energy

Google co-founder Sergey Brin’s huge wealth has been deployed in a variety of green initiatives. Like business partner Larry Page, Brin is a top investor in Tesla Motors, which developed the Tesla Roadster, a battery electric vehicle with a range of 220 miles. Google, with huge financial resources, is also going green. Last August it invested $10m to produce electricity from underground heat. The move is part of Google’s effort to pump hundreds of millions of dollars into green energy sources, starting with solar, thermal, high-altitude wind power and now, geothermal energy. Google’s shares have been hit hard in the recent stock- market turmoil but Brin is still worth at least £7.5 billion.
