Solar duty instead of universal conscription
Since thousands of years is the draft an extreme life-threatening concern. What would be compared to this a solar duty for roofs?
What are 9 month conscription in Germany economically alone? For some, having to take over the company of the parents very early the destruction of economically existence. Long journeys home have to be paid, instead of earning money. For luck, we live at least inside EU Europe in a peacefull time, where a conscript has not to think on deadly combat.
National defence can today not be seen only military. There is also the economic national defence. The increasing oil price caused by peak oik, the foreseeable shortage of crude oil with even more fast price increase and the climate change are such threats, where not the conscription and million of soldiers can help, but the solar duty and million of photovoltaic roofs.
When it was in earlier times "When You have suns, they have to serve at the military", it will be in the future, "When You have roofs, they have to serve for the electricity supply".
Germany has such a good law for photovoltaic furtherance, that it can only be called stupidity to create a building without photovoltaic roof.
It's forbidden to burn a banknote, something as stupid as to built in Germany a roof without photovoltaic.
