Renewable energy foes hike risk of climate catastroph­e

- Paul Krugman He writes for the New York Times.

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 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.

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 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.

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.

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 find better and cheaper ways to operate as they accumulate experience.

Recently David Roberts at Vox.com offered a very 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 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.

There is no longer any reason to believe that 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. In the 2016 election cycle the coal mining industry gave 97 percent of its contributi­ons to GOP candidates.

What the industry got in return for that money 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.

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.
