Offshore wind farm Cape Wind needs buyers for its power — The large, expensive and controversial Massachusetts wind farm needs customers, the Associated Press writes. Half of its 468-megawatt capacity has been sold to National Grid, but the other half has been turned down by top state utility NStar, which said it could find cheaper alternative energy elsewhere. Siemens is in talks to help finance the project, Bloomberg reports. The wind farm would use 130 of Siemens’ wind turbines.

Honda could launch electric car in China — The company unveiled the electric version of its Fit at the Los Angeles Auto Show, and plans to roll out electric vehicles in 2012 in Japan and the U.S. China has a “good chance” of seeing Honda’s electric cars, the company president said, according to Dow Jones Newswires. The Chinese government has made a strong commitment to electric vehicles, though BYD’s electrid hybrid reportedly stumbled due to the lack of charging infrastructure — so Honda must be assuming that will be in place by 2012 and beyond.

California to create carbon market — State regulators have approved the development of an exchange that will allow the top pollution emitters to use a market-based system to reduce emissions, Triple Pundit reports. The market would set allowances on emissions for top polluters that will decrease annually after 2014, and help set a price point that would drive long-term investment into energy efficiency and cleantech.

Tobacco could help build highly efficient batteries — Researchers at the University of Maryland have used a virus hosted by tobacco to improve energy capacity of batteries, CleanTechnica reports. The result is a battery that has 10 times the energy capacity of a traditional lithium-ion battery.
