The case for more energy

Instead, we should raise our clean energy production ambitions. We don’t want to replace 100% of our current dirty energy — we want to generate vastly more energy than we are currently using and make it zero carbon.

But the big picture question of how we orient ourselves is important. We shouldn’t be looking at our current energy usage and asking, “How can we get this much energy, but cleaner?” We should be looking at a 45-year energy diet and asking, “How can we use clean energy technology to shatter this barrier and open up incredible new vistas?”

Over the centuries, people have invented many different kinds of machines that help us do things and improve living standards. But in a very general way, what most of these inventions do is let us substitute some form of power for human effort. And as long as we were totally ignoring the costs of burning coal and oil, this was a great mechanism for... See more

But since the mid-1970s we’ve been increasingly aware of the limits and problems with this model, and it’s put us on an energy diet. Now when we invent something cool, we often have to say “too bad the energy requirements are so high.”

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
