Q & A What green technologies are you watching in 2005?

A: “Green buildings can generate clean power by using photovoltaic cells that generate electricity from sunlight. The California Energy Commission has a rebate program that pays up to 40 percent of the installed cost of photovoltaic systems. Once you factor in the federal and state tax credits, the system pays for itself in five to eight years.”—Vikas Shrestha, associate and sustainable design coordinator, Steinberg Architects
