This was a record-breaking year for rooftop solar power. It's booming across the country. But as more homeowners make their own power, electric utilities are making less money, and that's shaking up their business model.
Utilities in two states — California and Georgia — are handling the growth of solar in dramatically different ways.
Matt Brown recently got solar panels on his Oakland, Calif., home, but it's dark out right now — his panels aren't working. So Brown's appliances are running on electricity he's buying from his utility, Pacific Gas & Electric.
