The LA City Council wants the Department of Water and Power to install solar panels on government, commercial and industrial roofs all over the city. They would generate 400 megawatts of electricity, enough to power 100,000 homes. Friday, the Council put a bond measure on the March ballot, bypassing the appointed commission that oversees the DWP and without getting an outside analysis of the cost. But even supporters of alternative energy are raising questions. Why will the DWP install and own them, even on private buildings? What did the DWP's employee union have to do with getting Council approval? We look for answers.
