44% of Germany's electricity is currently from coal[1]. Hopefully they plan to reduce that, or this is a wee bit misguided.

As with any startup, you need to look at the trend. And Germany's use of renewable energy is increasing year by year, as shown here:

Germany is also phasing out fission plants, unlike some other countries, so renewables have to make up for those too.
