Roughly a billion dollars were spent in 2010 on renewables in Hawaii, including solar, wind and biofuel projects.
Pacific Business news writes that "...this is just the short list of technologies gaining momentum within the state's energy sector. Geothermal energy, solar hot water heating, electric and hydrogen vehicles, biodiesel, building retrofits that reduce energy usage, off-grid wind turbines that power homes and acres of grid-tied solar thermal energy also are expected to drive growth through 2011."
