Same as gasoline. There is not perfect solution.
I’m not strictly an environmentalist and would be fine with using hydrocarbons, because we have at least 10,000 years of hydrocarbons at current usage.
However, assuming that carbon really is a problem in the long-term, it’s good to ask whether or not that there are solutions.
The obvious and safest solution is nuclear energy.Nuclear plants can be made far safer now with much less waste product. But nuke is received with horror by the Left because it IS the cheapest and best. De-growth and de-population is the goal of the Left, not efficiency or clean safe growh and prosperity.
