Peel-off solar panels could make solar competitive with coal
Ultra-thin solar cells that can be "peeled off" from larger pieces of silicon like delicious fruit roll-ups could be the key to making solar competitive with coal, say researchers at MIT.

Why ‘market-based’ is poor criteria for solar policy
The energy market isn’t as free as we’d like to believe.Photo: USDAThis post originally appeared on Energy Self-Reliant States, a resource of the Institute for Local Self-Reliance’s New Rules Project. When it comes to solar policy in the U.S., there are three flavors: tax or cash incentives, long-term CLEAN Contracts, and solar renewable energy credit […]

Let’s cover Mt. Everest with solar panels
Less atmosphere between solar panels and the sun equals more power converted into electricity, says a new map of global solar irradiance. That means high-altitude communities — like every mountain chain from the Andes to Patagonia — could be the next frontier in producing solar power. In addition, the cool temperatures at altitude make panels […]

SolarShare bonds let citizens make money by financing local solar
You’re an earth-friendly person and want to go solar, but a large tree shades your house; or you’re a renter; or you don’t have $20,000 to drop on a solar power system. Or maybe you just want to get more than 0.5 percent interest on your savings account while getting a piece of the clean […]
