 While fuel switching may be the easiest option for hitting the 2020 and 2030 goals set by the Environmental Protection Agency’s (EPA’s) proposed Clean Power Plan, it may impede reaching longer-term climate targets said experts at an April 8 symposium hosted by the Central Texas Association for Energy Economics and the Energy Institute at the […]

Wind turbine blades, gearboxes, and generators get most of the attention both within and beyond the power industry. The focus is often on increased capacity and blade lengths, as well as drive train premature failures. That’s natural, because those rotating blades are the most visible part of a wind project. However, successful operation of a […]

Everyone loves efficiencies. Combining generation technologies can create a plant that’s more than the sum of its parts, but engineering challenges mean these projects are not for the faint of heart. When you think of “hybrids” these days, your first thought is probably of automobiles. But hybrids—hybrid power plants, that is—are starting to emerge in […]

Stacking perovskites, a crystalline material, onto a conventional silicon solar cell may dramatically improve the overall efficiency of the cell, scientists from Stanford University concluded in a new study. “Right now, silicon solar cells dominate the world market, but the power conversion efficiency of silicon photovoltaics has been stuck at 25% for 15 years,” explained […]
