Stanford scientists calculate the energy required to store wind and solar power on the grid
Stanford CA (SPX) Sep 17, 2013 - Renewable energy holds the promise of reducing carbon dioxide emissions. But there are times when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in batteries for later use seems like an obvious solution, but a new study from Stanford University suggests that might not always be the case. "We looked at batteries and other promising te ... morehttp://www.solardaily.com/reports/Stanford_scientists_calculate_the_energy_required_to_store_wind_and_solar_power_on_the_grid_999.html
