Breakthrough in Linking Renewables Makes Them Reliable in Germany

German researchers have found a way to overcome intermittency with renewable energy by linking different options in a unified system, reports Paul Brown at the Climate News Network. This refutes renewable critics, claiming the intermittency of sun and wind generated electricity needed fossil fuels as backups for such renewables to be viable. 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). Surplus energy can be stored as thermal energy. For Germany, which has turned its back on nuclear power and is investing heavily in all forms of renewables to reduce its carbon dioxide emissions, this is an important breakthrough. The country needs a large and stable electricity supply, and some doubted that this could be achieved longterm, without retaining nuclear or large fossil fuel plants. When many small producers work together, then regional differences in sun and wind intermittencies are balanced out in the grid and can be boosted by controllable biogas facilities.

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.

Breakthrough: Reliable Renewable Power Achieved Via Linking Them in a unified grid in Germany, reports Paul Brown at the Climate News Network. This refutes critics who insisted renewables would require fossil fuel backups to make them viable. Renewables  are becoming sustainable – hallelujah!


*Linked renewables avoid blackouts April 4, 2013 Linking solar, wind power and other forms of renewable energy together can obviate one of the main problems to their wider use – their intermittency.
