Installing rooftop solar panels has never been more affordable. UCS’s new solar infographic highlights the remarkable drop in the cost of rooftop solar in recent years, and how people are getting systems for even less, or even for zero dollars down.

Yesterday we talked about 10 ways to celebrate Earth Day with your family, save money, and cut your carbon emissions. Here’s a deeper dive into two of them: how to find and get rid of phantom loads or energy vampires, in ways that engage the kids.
