How will renewable power generation be affected by climate change? The case of a Metropolitan Region in Northwest Germany

Wachsmuth, J.; Blohm, A.; Gößling-Reisemann, S.; … - In: Energy 58 (2013) C, pp. 192-201

Energy systems that primarily use wind and solar power production are in need of long-term storage of electricity and fully developed transmission grids. Moreover, renewables-based energy systems may be strongly affected by climate change. We present two models that assess the impacts of climate...

A comparative sizing analysis of a renewable energy supplied stand-alone house considering both demand side and source side dynamics

Elma, Onur; Selamogullari, Ugur Savas - In: Applied Energy 96 (2012) C, pp. 400-408

Solar and wind energy use to supply the electrical demand of a stand-alone residential house is investigated. Combining solar and wind energy sources provide more reliable power source for stand-alone applications since they complement each other. Backup units (battery/supercapacitor) are also...
