Powered on stored sunshine "The night we hooked up our solar electrical system," recalls Minneapolis homeowner David Boyce, "we all stood outside looking at the lights shining from the windows. That's when the magic of solar power hit us: the panels just sit there in the sunlight all day, generating electricity and charging batteries. The sun sets, and we tap energy as we need it." Housecleaning inspired by dirty coal plant Observing a nearby coal-burning power plant inspired the Boyces to choose emissions-free solar energy. "Burning coal to make electricity emits carbon dioxide (CO2) and mercury," David explains. "CO2 is a greenhouse gas that helps cause global warming. Mercury is a neurotoxin that poisons our water. Whenever we turned on the lights, the coal plant had to run. We decided that we had to change how we got our electricity." |
