But here’s the thing: by the standards of today’s Republican Party, the Cheney report was enlightened, even left-leaning. One whole chapter was devoted to conservation, another to renewable energy. By contrast, recent speeches by Jeb Bush and Marco Rubio — still the most likely Republican presidential nominees — barely address either topic. When it comes to energy policy, the G.O.P. has become fossilized. That is, it’s fossil fuels, and only fossil fuels, all the way.

And that’s a remarkable development, because while it’s true that fracking has led to a boom in U.S. gas and oil production, we’re also living in an era of spectacular progress in wind and solar energy. Why has the right become so hostile to technologies that look more and more like the wave of the future?

Before I try to answer that question, a few facts about renewable energy.

Wind and solar used to have a reputation as hippie-dippy stuff, not part of any serious approach to our energy future, and many people still have that perception. But it’s way out of date. The cost of wind power has dropped sharply – 30 percent in just the past five years, according to the International Energy Agency.

And solar panels are becoming cheaper and more efficient at a startling rate, reminiscent of the progress in microchips that underlies the information technology revolution. As a result, renewables account for essentially all recent growth in electricity generation capacity in advanced countries.

Furthermore, renewables have become major industries in their own right, employing several hundred thousand people in the United States. Employment in the solar industry alone now exceeds the number of coal miners, and solar is adding jobs even as coal declines.

So you might expect people like Mr. Rubio, who says he wants to “unleash our energy potential,” and Mr. Bush, who says he wants to “unleash the Energy Revolution,” to embrace wind and solar as engines of jobs and growth. But they don’t. Indeed, they’re less open-minded than Dick Cheney, which is quite an accomplishment. Why?

Part of the answer is surely that promotion of renewable energy is linked in many people’s minds with attempts to limit climate change — and climate denial has become a key part of conservative identity. The truth is that climate impact isn’t the only cost of burning fossil fuels, that fossil-fuel-associated pollutants like particulates and ozone inflict huge, measurable damage and are major reasons to support alternative energy. Furthermore, renewables are getting close to being cost-competitive even in the absence of special incentives (and don’t forget that oil and gas have long been subsidized by the tax code.) But the association with climate science evokes visceral hostility on the right.

Beyond that, you need to follow the money. We used to say that the G.O.P. was the party of Big Energy, but these days it would be more accurate to say that it’s the party of Old Energy. In the 2014 election cycle the oil and gas industry gave 87 percent of its political contributions to Republicans; for coal mining the figure was 96, that’s right, 96 percent. Meanwhile, alternative energy went 56 percent for Democrats.

And Old Energy is engaged in a systematic effort to blacken the image of renewable energy, one that closely resembles the way it has supported “experts” willing to help create a cloud of doubt about climate science. An example: Earlier this year Newsweek published an op-ed article purporting to show that the true cost of wind power was much higher than it seems. But it turned out that the article contained major factual errors, and its author had failed to disclose that he was the Charles W. Koch professor at Utah State, and a fellow of a Koch- and ExxonMobil-backed think tank.

It’s unlikely, I guess, that energy policy will play as big a role as other issues, such as tax policy, in the 2016 election. But to the extent it does, you need to know what’s really at stake.

While politicians on the right may talk about encouraging innovation and promoting an energy revolution, they’re actually defenders of the energy status quo, part of a movement trying to block anything that might disrupt the reign of fossil fuels.
