From CNN online.
Arizona regulators are requiring utilities to get 15 percent of their electricity from renewable sources by 2025, with annual increases of roughly 1 percent.
The Solana plant will bring APS to around 5 percent in 2011, said Don Robinson, the utility’s senior vice president of planning and administration.
Unlike most solar energy, Solana will use the sun’s heat, not its light, to produce power. Gila Bend can get as hot as 120 degrees in the summer.
Abengoa CEO Santiago Seage said the plant will use thousands of giant mirrors to harness the sun’s heat. That will heat up liquids, which will spin turbines — just like coal or other power plants but without the pollution.
