Eight years ago this week, I wrote a column titled, “Why Trump won’t stop the clean energy revolution.” Calling global warming a hoax, businessman and reality TV star Donald J. Trump had just been elected with a promise to save coal jobs and pull the U.S. out of the Paris climate accord. 

Climate activists were deeply distraught then, as now. I wrote in 2016, “Reading the news Wednesday morning was like waking up from a nightmare to discover that there really is a guy coming after you with a meat cleaver.”

But as I also wrote, there is only so much damage a president can do when technology, popular opinion and – especially – economics don’t support his agenda. Trump couldn’t save the coal industry (though he tried). Instead, his administration oversaw a 24% decline in coal employment. And where coal supplied 30% of U.S. electricity in 2016, by the time Trump left office it had fallen to 20%. 

In the intervening years, Trump seems to have lost interest in coal mining, even as he continues to embrace fossil gas production. His enthusiasm for gas fracking fits with his drill-baby-drill approach to energy, but it was also intended to win over voters in Pennsylvania, a major producer of shale gas. Ironically, the gas industry insists on calling methane “clean” precisely because burning it emits less CO2 than coal. 

While coal was dying, wind and solar were well on their upswing when Trump took office in 2017, and they continued to advance through his first administration. By 2020, wind and solar had become the cheapest forms of new electric generation. Today, renewable energy supplies more than 21% of the nation’s electricity, while coal’s share has dropped further, to just 16%. Trump or no Trump, technological advances and a thirst for cleaner energy continue to drive new wind and solar generation.

Indeed, the offshore wind industry – famously reviled by Trump – wasted no time this week in congratulating its erstwhile foe on his victory and insisting, hilariously, that his election is a big win for the industry. The first Trump administration, they noted hopefully, “laid out the fundamental framework for our modern offshore wind industry.”

Well, okay. From their lips to Trump’s ears. Trump is hardly known for consistency, and it is not impossible to imagine him softening his position on an industry that is creating well-paying jobs for the blue-collar workers who make up a portion of his base. His Virginia acolyte, Republican Gov. Glenn Youngkin, boasts of overseeing the building of the nation’s largest offshore wind farm. Why shouldn’t Trump pivot? 

Early in the Republican primaries, one candidate opined that all the solar panels and batteries sold in the U.S. are made in China. That wasn’t actually true. For years one U.S. company, First Solar, has ranked among the world’s top ten solar panel manufacturers. Among the domestic manufacturers of both EVs and batteries, one of the largest is Tesla, whose CEO Elon Musk is now a Trump darling. It is going to be fascinating to find out whether Musk uses his influence to benefit the clean energy transition generally, or only himself. 

Yet the notion that China dominates solar and battery production is also not wrong. China is eating our lunch on clean energy. Chinese companies produce 80% of the world’s solar panels and more than half of its electric vehicles. Sadly, perhaps, these are not cheap imitations of superior American products. They are world-leading technology. 

Chinese dominance of the world market was a major reason that President Joe Biden’s signature climate law, the Inflation Reduction Act (IRA), put so much emphasis on supporting domestic manufacturing. Tariffs on Chinese goods, Trump’s preferred approach, help U.S. companies compete for American consumers, but they don’t support an export market when other countries produce better goods for less money. Even at home, critics note, tariffs mostly just raise prices.

Yet Trump has vowed to repeal the IRA, and given that Congress passed it without Republican support, there is certainly a danger that a Republican Congress will comply. On the other hand, observers note that 80% of the manufacturing tax credits have gone to red states, and this August, 18 House Republicans signed a letter to Speaker Mike Johnson asking to keep the credits. 

I don’t want to sound too optimistic. Wait, let me rephrase that: I don’t feel optimistic at all. We are facing headwinds today that weren’t around in 2016. At that time, gains in energy efficiency meant electricity demand was not increasing, in spite of a growing population. With wind and solar displacing coal, there was a clear pathway for CO2 emissions from the electric sector to continue falling. 

Today, however, the skyrocketing demand for electricity from data centers threatens the progress we’ve made on clean energy. It remains to be seen whether artificial intelligence will unleash efficiency gains and novel technologies that can put carbon reductions back on track. Right now, though, tech companies are so desperate for power that they will take it from wherever they can get it, and regardless of carbon content.  (I notice, though, that they still want it to be cheap and are happy to greenwash it to meet their sustainability goals). 

Perhaps the biggest change from eight years ago is simply that we are that much closer to reaching catastrophic climate tipping points. 2023 was the warmest year on record, and 2024 is on track to surpass it. The effects are evident in the number and costliness of severe weather and wildfires made worse by global warming. (Just ask insurance companies.) It is frustrating, to say the least, to contemplate losing the next four years to an administration that thinks climate change wouldn’t be an issue if we would just stop talking about it.  

Yet Americans of all political stripes continue to support renewable energy by wide margins. And apart from a small minority of vocal climate deniers, most Americans want the U.S. to take stronger action on climate. 

This election revealed deep fault lines among the American public, but one thing we all have in common is the faith that our ability to solve intractable problems is stronger even than our tendency to wish the problems away. 

That’s why, even in the face of such serious headwinds, the clean energy revolution will continue.
