The California Energy Commission Aug. 28 approved spending more than $66 million of Proposition 39 funds for energy efficiency and solar retrofits at 244 schools. \u201cNationally, K-12 schools spend more money on energy than computers and textbooks combined,\u201d said commissioner Andrew McAllister. School districts, offices of education and schools apply for the funds via an energy expenditure plan submitted to the Energy Commission. The voter-approved Prop. 39 closed a corporate income tax loophole. It directs the revenue to the General Fund and the Clean Energy Job Creation Fund, with about $550 million available annually for appropriation.
