Is Renewable Energy’s Biggest Problem Solved?

Share

German researchers have found a way to overcome one of the problems with renewable energy — the fact that it is not always available — by linking different options in a unified system.

Critics of renewables have always claimed that sun and wind are only intermittent producers of electricity and need fossil fuel plants as back-up to make them viable. But German engineers have proved this is not so.

By skillfully combining the output of a number of solar, wind and biogas plants the grid can be provided with stable energy 24 hours a day without fear of blackouts, according to the Fraunhofer Institute for Wind Energy and Energy System Technology (IWES) in Kassel.
