How much (if at all) does Germany rely on natural gas for energy production? Is there a risk of power loss if the natural gas is cutoff or is only heating/​cooking at risk?
Yes, there is that risk. In 2021 about 10% electricity with natural gas, and in addition hard coal (where the main source is Russia, too) 9%. This year probably more, because two additional nuclear power plants have been closed at the end of 2021.
But these numbers underestimate the problem: Natural gas is used to even out fluctuations in the production of electricity with wind or solar (33% of electricity in 2021, 23% wind, 10% solar). Therefore a lack of gas could seriously destabilise electricity production.
Because of that risk I would predict that the use of gas for electricity will have priority compared to private heating, decreasing the risk of electric grid breakdown but increasing the risk of supply shortages for private households (and industrial production, which uses even more natural gas than is used for heating).

There is a variety of solar power camping gear that can be used for showers, cooking, lighting, etc. Some subset of this might be worth looking at.
