California Went Big On Rooftop Solar. Now That’s A Problem For Landfills
California has been a pioneer in pushing for rooftop solar power, building up the largest solar market in the U.S.
Beginning in 2006, the state, focused on how to incentivize people to take up solar power, showered subsidies on homeowners who installed photovoltaic panels but had no comprehensive plan to dispose of them. Now, panels purchased under those programs are nearing the end of their typical 25-to-30-year life cycle.
The measure exceeded its goals, bringing down the price of solar panels and boosting the share of the state’s electricity produced by the sun. Because of that and other measures, such as requirements that utilities buy a portion of their electricity from renewable sources, solar power now accounts for 15% of the state’s power.
