'Sun in a box' would store renewable energy for the grid

Engineers have come up with a conceptual design for a system to store renewable energy, such as solar and wind power, and deliver that energy back into an electric grid on demand. The system may be designed to power a small city not just when the sun is up or the wind is high, but around the clock. … read more

Answering the Internet’s Pressing Solar Questions Using The Open PV Project

While solar power continues its accelerated adoption in the U.S. market, the National Renewable Energy Laboratory (NREL) tracks photovoltaic (PV) installations nationwide. As the sector evolves, this tool provides invaluable access to public data. The Open PV Project, run and operated by NREL, tracks and makes publicly available such solar data and provides vital information […]

Explaining the plummeting cost of solar power

The dramatic drop in the cost of solar photovoltaic (PV) modules, which has fallen by 99 percent over the last four decades, is often touted as a major success story for renewable energy technology. But one question has never been fully addressed: What exactly accounts for that stunning drop? A new analysis has pinpointed what caused the savings, including the policies and technology changes that mattered most. … read more
