Sorry, but some of your statements are only partially correct. In fact germany exports more energy than it imports. ( https://www.ise.fraunhofer.de/en/press-media/news/2016/germa... ) Also the popularity of diesel might have other factors as well.
Regardless of exporting a lot of electricity, they are also now completely dependent on French nuclear power for energy security. German renewable sources are intermittent. In short, they produce energy when there is enough wind and when the sun shines, and both of those are conditions that correlate heavily over all of Germany. German electricity demand largely does not match them -- unlike in hotter climates, air c…
One example is French excess nuclear energy in the summer (in central Europe AC are very uncommon, so energy demand is low when it's hot): Germany can more easily switch off renewable plants and import French nuclear power, yet still is a net exporter.
