U.S. President Donald Trump is simultaneously an expert on wind power and completely baffled by it by his own estimation, anyways.

I never understood wind, Trump said during a speech at conservative nonprofit Turning Point USAs Student Action Summit on Saturday, according to the official White House transcript. You know, I know windmills very much. I have studied it better than anybody.

But the rest of Trumps speech implies that only the first part of that statement is true: he knows very little about wind power other than the fact that hes against it.

Trump also cited the process used to produce turbines as a mark against them.

They are made in China and Germany mostly, very few made here, almost none, he said, but they are manufactured, tremendous if you are into this tremendous fumes and gases are spewing into the atmosphere.

But as pointed out by The Hill, researchers from the American Wind Energy Association found that a typical wind project repays its carbon footprint in six months or less. Meanwhile, the benefits of the devices can last fora typical lifespan of 20 to 25 years a good investment no matter how you look at it.

Another of Trumps beefs with wind turbines? They kill birds.

You want to see a bird graveyard? Trump asked the audience. You just go. Take a look. A bird graveyard. Go under a windmill someday. Youll see more birds than youve ever seen ever in your life A windmill will kill many bald eagles. Its true.

Though its hard to say for sure how many bald eagles fall victim to wind turbines, the devices do kill approximately 234,012 birds in the U.S. every year, according to the U.S. Fish and Wildlife Service.

But for comparison, collisions with glass buildings like the ones Trump has made a career stamping his name on kill 599,000,000 birds every year. Thats 2,559 times more birds than turbines.

Trump didnt mention that during his speech, but he did trot out anotherfrequent claim: that wind turbines negatively impact property values and once again, its clear he doesnt have his facts straight.

So they make these things and then they put them up, he told the audience. And if you own a house within vision of some of these monsters, your house is worth 50 percent of the price.

While some smaller studies have found that a nearby wind farm can decrease a homes value, larger studies including a 2013 analysis of more than 50,000 homes in nine states concluded that turbines have no negative impact on property values.

Still, given that Trump has previously claimed that wind turbines decrease home values by 75 percent, this new 50 percent figure does get him closer to the truth so while he clearly doesnt know windmills very much, his claims about wind energy do appear to be getting slightly most accurate than theyve been in the past. Very slightly.
