Germany recently broke its record for renewable energy generation by having 85 percent of its electricity come from renewable sources over the last weekend of April. On April 30, the bulk of electricity consume came from a mix of solar, wind, biomass and hydroelectric power. The record breaking clean energy was thanks to breezy and sunny weather in the north and warm weather in the south, providing plenty of sunlight and wind.
"Most of Germany's coal-fired power stations were not even operating on Sunday, April 30th, with renewable sources accounting for 85 per cent of electricity across the country," said Patrick Graichen of Agora Energiewende Initiative. "Nuclear power sources, which are planned to be completely phased out by 2022, were also severely reduced."
The country's Energiewende program aims to see a clean energy revolution by 2050. Graichen says that the tide will really start to turn by 2030 when many of the investments made by Germany since 2010 will come to fruition and majority or even totally renewable-powered days will become the norm.
Will producing its energy locally confer a strategic economic advantage on Germany, or is it just for bragging rights?

The main strategic advantage of this is that it will help the Germans tremendously if the Russians try to cut off their natural gas supply (as they've at least threatened to do before).
No, it does not help at all. And no, it would definitely not help Russia at all either to do so.
I live in Germany. My flat has gas for heating. My *energy* consumption is 5x gas and 1x electricity. And I don't even use much heat in winter - this is mostly to heat water for 15 min shower! So, if gas is cut, then I have no hot water for shower anymore or I need to use 5x as much electricity as I do now to heat the water - ok, maybe 4x as it would be more efficient than 80%.
It's easy to BS about energy independence while most of the energy usage is fossil fuel. Electricity is not anywhere near the main energy usage of our economies.

These "feel good" summaries miss the entire point of why our economy is 100% reliant on fossil fuels and will remain so for at least another generation. Hint: *storage*

Never head of heat pumps? They have a COP (Coefficient of performance) of around 3-3.5.
So you need around 1.5 "X" of electricity to get 5 "X" of heat.
So practically, gas might be 80% efficient while electricity with an heat pump is 300% efficient.

Excellent point about heat-pumps. The "outlet" of a german winter-heating heat pump would probably connect to the fridge anway :)
Also there are induction cookers. They generate a eddy current in the metal cook ware (only). The hot pan or pot will then heat the food. Very efficient and "dangerous" because needs to be baby-sitted because it cooks sooo fast : https://en.m.wikipedia.org/wiki/Induction_cooking [wikipedia.org]
