http://www.unendlich-viel-energie.de The secure and constant provision of power anywhere and at anytime by renewable energies is now made possible thanks to the Combined Power Plant. The Combined Power Plant links and controls 36 wind, solar, biomass and hydropower installations spread throughout Germany. It is just as reliable and powerful as a conventional large-scale power station.
The Combined Renewable Energy Power Plant shows how, through joint control of small and decentralised plants, it is possible to provide reliable electricity in accordance with needs. The Combined Power Plant optimally combines the advantages of various renewable energy sources. Wind turbines and solar modules help generate electricity in accordance with how much wind and sun is available. Biogas and hydropower are used to make up the difference: they are converted into electricity as needed in order to balance out short-term fluctuations, or are temporarily stored. Technically, there is nothing preventing us from 100 per cent provision with renewables.
The Combined Power Plant is an initiative of the companies Enercon GmbH, Schmack Biogas AG and SolarWorld AG, and is supported by many partners from the renewable energy sector.

I think this video painted a bit too rosy picture for wind power. The power from wind increases exponentially with wind speed, but the frequency of such winds is quite low.
In effect, most energy is produced in big surges that last from few hours to few days, and the rest of the time the mills produce very little.
Half of the energy with wind power may come in in just 15% of the running time, which is roughly equivalent to getting a whole week's load in one or two days, and then just dribbles for the rest of the week.
You need very large water dams for that sort of energy reserves on a national scale, and water power isn't without environmental impact either. Methane release from rotting biomatter is impossible to control in large dams due to the sheer size of them.
