Renewable sources can provide stable power

Renewable sources can provide stable power
Renewable energy sources - an area in which Germany is a leader - are becoming increasingly important for the worldwide power mix. Nevertheless, experts are still deliberating which market model is best for transitioning to renewables. However, one of the major technological challenges in this regard, namely balancing the fluctuations that are caused by wind and solar power, may soon be solved. The research project Kombikraftwerk 2 (Combined Power Plant 2) shows that a Germany-wide power grid could be stably operated even if it were fed only with electricity from renewable sources. The project partners (which included Siemens' global research unit Corporate Technology) also demonstrated that solar, wind, and biogas power plants can contribute to system stability if they are connected with one another to form an intelligently controlled power plant. http://phys.org/news/2013-12-renewable-sources-stable-power.html#nwlt
