On the other hand, if our “reduce by 2030” goal is a milestone toward “zero by 2050,” then it makes little sense to spend a lot of time or money switching from coal to gas. Instead, we’re better off pursuing two strategies at the same time: First, going all out to deliver zero-carbon electricity cheaply and reliably; and second, electrifying as widely as possible—everything from vehicles to industrial processes and heat pumps, even in places that currently rely on fossil fuels for their electricity.
