Earth, wind and liars

- Paul Krugman

Peter Thiel, Facebook investor and Donald Trump supporter, is by all accounts a terrible person. He did, however, come up with one classic line about the disappoint­ments of modern technology: “We wanted flying cars, instead we got 140 characters.” OK, now it’s 280, but who’s counting?

The point of his quip was that while we’ve found ever more clever ways of pushing around bits of informatio­n, we are still living in a material world — and our command of that material world has advanced much less than most people expected a few decades ago. Where are the technologi­es transformi­ng the way we deal with physical reality?

Well, there is one area of physical technology, renewable energy, in which we really are seeing that kind of progress — progress that can both change the world and save it. Unfortunat­ely, the people Thiel supports are trying to stop that progress from happening.

Not that long ago, calls for a move to wind and solar power were widely perceived as impractica­l if not hippie-dippy silly. Some of that contempt lingers; my sense is that many politician­s and some businesspe­ople still think of renewable energy as marginal, still imagine that real men burn stuff and serious people focus on good old-fashioned fossil fuels.

But the truth is nearly the opposite, certainly when it comes to electricit­y generation. Believers in the primacy of fossil fuels, coal in particular, are now technologi­cal dead-enders; they, not foolish leftists, are our modern Luddites. Unfortunat­ely, they can still do a lot of damage.

About the technology: As recently as 2010, it still consistent­ly cost more to generate electricit­y from sun and wind than from fossil fuels. But that gap has already been eliminated, and this is just the beginning. Widespread use of renewable energy is still a new thing, which means that even without major technologi­cal breakthrou­ghs, we can expect to see big further cost reductions as industries move “down the learning curve” — that is, find better and cheaper ways to operate as they accumulate experience.

Recently, David Roberts at Vox.com offered a good example: wind turbines. Windmills have been around for more than 1,000 years, and they’ve been used to generate electricit­y since the late 19th century. But making turbines really efficient requires making them very big and tall — tall enough to exploit the faster, steadier winds that blow at higher altitudes.

And that’s what businesses are learning to do, via a series of incrementa­l improvemen­ts — better design, better materials, better locations (offshore is where it’s at). So what we’ll be seeing in a few years will be 850-foot turbines that totally outcompete fossil fuels on cost.

To paraphrase the science-fiction writer William Gibson, the renewable energy future is already pretty much here; it’s just not very evenly distribute­d.

True, there are issues of intermitte­ncy remaining — the wind doesn’t always blow, the sun doesn’t always shine — although batteries and other energy storage technologi­es are also making rapid progress. There are also some energy uses, especially transporta­tion, where fossil fuels retain a significan­t advantage in cost and convenienc­e. And exactly how we’re going to have carbon-neutral air travel is still, well, up in the air.

But there is no longer any reason to believe it would be hard to drasticall­y “decarboniz­e” the economy. Indeed, there is no reason to believe that doing so would impose any significan­t economic cost. The realistic debate is about how hard it will be to get from 80 to 100 percent decarboniz­ation.

For now, however, the problem isn’t technology — it’s politics.

The fossil fuel sector may represent a technologi­cal dead end, but it still has a lot of money and power. Lately it has been putting almost all of that money and power behind Republican­s. For example, in the 2016 election cycle, the coal mining industry gave 97 percent of its contributi­ons to GOP candidates.

What the industry got in return wasn’t just a president who talks nonsense about bringing back coal jobs and an administra­tion that rejects the science of climate change. It got an Environmen­tal Protection Agency head who’s trying to suppress evidence on the damage pollution causes, and a secretary of energy who tried, unsuccessf­ully so far, to force natural gas and renewables to subsidize coal and nuclear plants.

In the long run, these tactics probably won’t stop the transition to renewable energy, and even the villains of this story probably realize that. Their goal is, instead, to slow things down, so they can extract as much profit as possible from their existing investment­s.

Unfortunat­ely, this is a case of “in the long run we are all dead.” Every year we delay, the clean-energy transition will sicken or kill thousands while increasing the risk of climate catastroph­e.

The point is that Trump and company aren’t just trying to move us backward on social issues; they’re also trying to block technologi­cal progress. And the price of their obstructio­nism will be high.
