In the wake of the Paris climate agreement, the German debate currently revolves around the political goal that the global energy supply must make do without coal, oil and natural gas, and that these resources must remain in the ground.
That is too defensive and backward looking.
The more future-oriented message is: We can make do without fossil fuel and nuclear energy! That’s because the cost of renewable energy, especially solar, continues to fall. Like the Stone Age, the fossil-nuclear age will come to an end because there are better and cheaper alternatives.
We will then be able to turn our backs on two key technologies that date back to the last century: steam engines in power plants and internal combustion engines in automobiles. Electrification and digitization will modernize economies. Electric cars and electric sources of heat will become unstoppable, because these technologies are better and more convincing.
