Israeli-Californian solar thermal energy plant developer BrightSource won both first place and the overall winner award last week in the AlwaysOn GoingGreen 100 Top Private Companies list, that recognizes the top private green tech companies that are creating new business opportunities and transforming the world`s largest industries to improve sustainability.

AlwaysOn, which has emerged as a leader in the “open media” revolution, received more than 400 nominations, which were evaluated based on innovation, market potential, commercialization, stakeholder value, and media buzz.

BrightSource Energy emerged a double winner for the following reasons: It uses a “powertower” which is far less expensive to build and operate; an innovative solar field that doesn’t require any plumbing and can remain irregular and unimproved, greatly lowering costs; and in addition, the company has taken the lead in securing substantial project financing and approvals, signing the world`s largest solar deal with Edison in Southern California earlier this year and is poised to become a significant supplier of electricity.

BrightSource, which was featured in ISRAEL21c this <a href=” http://www.israel21c.org/index.php?option=com_content&view=article&id=2372:israel-and-california-cut-worlds-largest-solar-energy-deal-&catid=58:environment&Itemid=101″><strong>February</strong></a>, and the other winners will be honored from September 14-16 at GoingGreen West 2009 in San Franciso.
