Blueprint 100% Renewable Energy Base for Germany
Hans-Martin Henning and Andreas Palzer of the Fraunhofer Institute for Solar Energy Systems in Germany have set up a computer model for a 100% renewable energy base for Germany and have used that model to find the most cost effective configuration. The result can be seen in the diagram.
The energy inputs are:
| Source | Power [GW] | Annual energy [TWh] |
|---|---|---|
| Solar panels | 252 | 246 |
| Onshore wind | 200 | 360 |
| Thermal solar | 182 | 148 |
| Offshore wind | 85 | 297 |
| Hydro-power | 5 | 21 |
| Electricity import | 0 | 0 |
Scale the numbers up and you have the solution for Europe, with significant changes in numbers for individual nations. The cost of this renewable energy system would not be higher than our current fossil fuel based energy system.
