Imagine a Europe that ran on solar and wind power: whose cars ran on locally provided electricity, and whose homes were heated by electric air-source heat pumps. That Europe would not be funding Putin’s Russia, and it would be far less scared of Putin’s Russia—it could impose every kind of sanction, and keep them in place until the country buckled. Imagine an America where the cost of gas was not a political tripwire, because if people had to have a pickup to make them feel sufficiently manly, that pickup would run on electricity that came from the sun and wind. It would take an evil-er genius than Vladimir Putin to figure out how to embargo the sun.
