Over the centuries, Matthew Yglesias reminds us, 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 progress — you invent new ways to do things by burning coal and oil, so then you burn more coal and oil.
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.”
But as Ryan Avent (from whom I borrowed that chart) and others have written, this is a backward way of looking at things. The turn toward conservation and efficiency was a necessary evil in an era when we couldn’t come up with a better way to deal with geopolitical instability linked to oil and pollution linked to all forms of fossil fuels.
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.
What difference does it make in how you look at it?
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 replace much more than 100% of current gas, coal, and oil with zero-carbon sources of electricity and use that to literally power a bold new era of rapid economic growth.
I find that this vision tends not to be intuitively compelling to a lot of people who are accustomed to living in the efficiency era. But let’s just imagine a world with small modular nuclear reactors and advanced geothermal energy production — a world in which we have plenty of baseline power. As our ability to make batteries gets better and better, we can put them all in vehicles rather than using them to address intermittent renewables. Then when the sun shines or the wind blows, we have even more power that we can use for stuff that doesn’t need to be on all the time. It’s a world of energy abundance — Lewis Strauss’ dream of electricity that’s “too cheap to meter.”
