In the “energy is a necessary evil” frame, we look at our current electricity needs and then ask, “How can we generate all that from zero-carbon sources?” In the alternate framing, you say that to the extent we can develop affordable, zero-carbon sources of electricity, we want to generate tons and tons of electricity. Ideally, we would want to rep... See more
