Germany should not accept roubles as the payment currency for Russian natural gas

1. The shortage in the natural gas supply will increase the natural gas price: half will cost as a whole and Germany selling half of the imported Russian gas will gain

2. However, this price increase will suppress the production of metals and plastic and thus the whole industrial production 

3. The fall in energy supply and industrial production will decelerate building new green energy facilities which need a lot of energy and materials

4. The natural gas price increase will prohibit the production of fertilizers and heating of the greenhouses

5. Oil and thus diesel price rise will suppress transportation of goods and suppliers to industry and retailers

6. Agriculture without diesel and fertilizers will stop food production starting with the upcoming sowing 

7. Underground gas storage will be empty and house heating will cost too much during the next winter
