The budding popularity of solar panel and battery systems, driven by a drop in lithium-ion battery prices, has thrown a lifeline to Germany's moribund solar sector.
The proposed act would require Washington, D.C., to source 100 percent of its electricity from renewable sources by 2032.
Each time the electricity powers off in Kathmandu, thousands of diesel generators rumble to life, spewing noxious particulate matter, or PM2.5.
While others work on improving batteries and turning air compression into an energy-storage solution, the ARES team is re-purposing the simple ideas behind water towers to address a gap in our solar-power infrastructure.
Worries about oil and gas hog the airwaves. But copper is also essential to keep the world running: It threads through your house, your computer, your eco-correct hybrid car.

One small but important study shows that we could save money — and our behavior could change — if we were just given the right information.
Some environmental advocates say the federal government is ignoring the real future of solar energy: photovoltaic cells on almost every roof. But even supporters acknowledge rooftop solar isn't the complete answer to the energy question — yet.
