The Kassel University in Germany did a study on combining renewable energy sources for 100% power supply. The homepage is to be found at http://www.kombikraftwerk.de/index.php?id=27. The week point in the scenario is the lack of heat production that is strongly interact with the power production, also for a renewable power plant. I would recommend that the University in Kassel, utilized their own expertise from Prof. Klaus Vajen, an expert in solar heating, also large-scale.

The point of the study is, that it can be shown that the whole of Germany can be supplied with renewable energy. A simple statement, that lead me to the below memory:

Just to mention, similar scenario where made in the 80′th for the Nordic countries by among others the Technical University of Denmark, Niels I. Meyer.

It sees, that Al Gore did make an impression onto the Danish government. After 5-6 years of complete ignorance, the Danish government did publish a new energy plan. The main focus are:

* 30% renewable energy in 2025.
* 15% reduction of consumption of fossil fuel.
* A stabilisation of energy demand at the current level.
* 10% of energy consumption in the transport sector must come from renewable energy sources by 2020.
* A doubling of investments into energy research to one billion Danish crones annually.

Even though, focus in not on Solar Energy, I assume that we will get a new opportunity for working on large-scale solar heating and seasonal thermal storage technologies. So I hope to have many more news in the future for a brighter, sustainable world.
