Connecticut-based anaerobic digestion (AD) facility, Quantum Biopower, announced the completion of a solar rooftop installation on Quantum’s Southington anaerobic digestion facility in partnership with Commercial Solar Works (CSW). This installation reduces electricity demand and increases savings for the food-waste-to-electricity plant by adding a second source of renewable energy.
Stanford researchers have developed a water-based battery that could provide a cheap way to store wind or solar energy generated when the sun is shining and wind is blowing so it can be fed back into the electric grid and be redistributed when demand is high.
Community solar capacity in the United States more than doubled between 2016 and 2017, from 347 megawatts (MW) at the end of 2016, to 734 MW at the end of 2017, according to the “Community Solar Program Design Models” report released by the U.S. Smart Electric Power Alliance (SEPA). At present 228 utilities in 36 states have active community solar programs.
The California Energy Commission announced yesterday the adoption of building standards that require solar photovoltaic systems starting in 2020. The building energy efficiency standards, which are the first in the nation to require solar, will reduce greenhouse gas emissions by an amount equivalent to taking 115,000 fossil fuel cars off the road.
