You again didn't answer my question. How much storage should we have?

Reliability and not relying on other countries are extremely important issues. They are widely held as important issues by many people. I would rather pay more to not rely on another country and to ensure we can have consistent production.

There can be embargo on countries. What happens to Russia in this situation? Maybe they can get power from China, but maybe not. They will have thousands of people freeze to death without power.
