I my talk I will show that we can produce all our electricity from renewable sources.

This is a question concerning the worldwide potentials for renewable electricity production. The techniques for their use have to be considered. Techniques like electricity production via solar thermal power plants and hydropower and finally we will focus on wind energy or some more speculative options. For each of these options of electricity generation I am going to point out the characteristics with regard to their specific temporal behaviour and the costs to be expected.

We will see that the temporal behaviour significantly changes with the size and the selection of the catchments area used for the electricity generation.

We will also touch on the topics of backup and storage needs and the subject of grid capacities.

The answer is clearly yes, it is possible to come to a totally renewable electricity supply.

The next question – much more difficult to answer – is:

Can we afford that?

Yes, it will be shown that a change to a totally renewable electricity supply is neither a technical nor a economic problem but mainly a political task.

How could that work in an optimal case?

As an output of a mathematical optimisation we will see that a spacious international utilisation of renewable potentials for a common electricity supply within a strongly interconnected international grid is the optimal solution resulting in the cheapest renewable electricity.
