Why it’s green: The Milwaukee-based firm, long a leader in green buildings, is working on batteries for hybrid autos.
Key fact: Boosting buildings’ efficiency provides more than a third of revenue, but the company makes parts for cars and homes—two of the economy’s weak spots. Shares fell when it cut earnings estimates.
Why it’s green: Ormat develops, builds, and runs geothermal power plants, which use heat from below Earth’s surface to convert water to steam that powers turbines.
Key fact: The company operates a dozen geothermal sites, with about 400 megawatts of generating capacity. It expects to add 111 MW by the end of 2008 and 73 more by the end of 2009, and then maintain a growth rate of at least 100 MW a year in 2010 and beyond.
Why it’s green: SunPower, which is majority-owned by Cypress Semiconductor, makes high-efficiency solar cells and solar panels.
Key fact: The company was recently hired by Florida Power & Light to build a 25-MW photovoltaic solar-power plant near Sarasota, Fla. The plant is expected to be the largest in the United States.
