But gas is a choice, Russian gas is even more of a choice. Gas is not needed to run any economy, except maybe as peaker plants if your hydro resources are weak. But even then pumped storage is possible.
Gas is not needed for power. Gas is not needed for heating. Gas is not needed for industry. Gas is not needed for anything.
There are competitive alternatives. Gas is a choice. And as Jerome says, choose differently or stop whining. Peak oil is not an energy crisis. It is a liquid fuel crisis.
