I was assuming the graph includes estimated energy consumption from all energy sources, including personal once. I agree, might be hard to estimate a realistic value.

Let's agree, the graph is mainly showing the decline of the not so competetive energy intensiv economy sectors, like chemicals, steel etc. Sure, that might be true, but the speed this happens is still shocking. I doubt, the gap can be filled with less energy intensiv economical activities that fast, without losing any wealth.

Could you provide a source, where the government is pointing out less overall energy consumption as a particular goal?

I think, that goal doesn't makes sense at all. Because we could just stop any activity to achieve the goal. What matters most is how the energy is used and produced. Besides that, Germany will have to switch from producing energy intensiv goods, like chemicals and steel, to importing those goods. Probably, with much worse environmental impact.

I am afraid, but if the German government is selling this as a success, we are even more fucked up, that I thought.

Now, what can we do to help fixing it?
