After a “comprehensive review” of the project and a revised agreement with French power generator EDF, the UK Department for Business, Energy, and Industrial (DBEI) Strategy […]

After years of incremental advances, a variety of innovations both simple and exotic are promising to boost the output of solar photovoltaic (PV) systems as much as 30% over current technologies—if the market can be convinced to adopt them. The Dawn of SiC For a generation, silicon has been the go-to material for semiconductor substrates. […]

A strategy rolled out by the Department of Energy (DOE) and Department of the Interior (DOI) to enable 86 GW of offshore wind capacity in the U.S. by 2050 highlights a number of key hurdles, including those related to technology, regulations, the environment, and markets. The DOE’s and DOI’s September 9–released joint document, “National Offshore […]

The global solar market has moved beyond its early, uncertain, freewheeling days.
