Wind farms perform best when the sun is out
When set up in groups, wind turbines in the front rows cast a wind shadow on those behind them, lowering their performance. These effects dissipate fastest under convective conditions, say EPFL researchers ...
Europe braces for 'unprecedented' power issues from solar eclipse
Europe's power operators are bracing for potential disruption from the solar eclipse expected Friday, which will knock out almost all solar-generated electricity in an "unprecedented" test for the network.
Solar could meet California energy demand three to five times over
In the face of global climate change, increasing the use of renewable energy resources is one of the most urgent challenges facing the world. Further development of one resource, solar energy, is complicated ...
