Don't blame turbines for Texas crisis

A steep decline in energy generated by fossil fuels and nuclear power plants was largely responsible for the power outages in Texas during the deep freeze that recently gripped the state, according to the operators of the state's power grid.

Despite that fact, several high-profile conservative figures - including the state's governor - have wrongly placed the blame for power outages on wind turbines and have tied the issue to the Green New Deal, legislation Democrats proposed in 2019 with the aim of creating jobs and significantly reducing the country's greenhouse gas emissions. It didn't pass in either the House or the Senate, but its tenets are still popular among progressives. President Joe Biden has supported its framework.

Texas Gov. Greg Abbott, a Republican, told Fox News host Sean Hannity on Feb. 16, "This shows how the Green New Deal would be a deadly deal for the United States of America. … Our wind and our solar, they got shut down and they were collectively more than 10% of our power grid, and that thrust Texas into a situation where it was lacking power in a statewide basis."

The host of another Fox News show went even further. Tucker Carlson started a segment on his Feb. 15 show, saying, "The Green New Deal has come, believe it or not, to the state of Texas." Meanwhile, a graphic showing a frozen water feature in the "splash and play kids zone" of a Dallas-area hotel played over his shoulder - it looked vaguely like a windmill.

Later, Carlson said, "Green energy inevitably means blackouts. … Green energy means a less reliable power grid. Period. It means failures like the ones we're seeing now in Texas. … It's science."

Other public officials echoed these claims - Rep. Lauren Boebert of Colorado, Rep. Andy Barr of Kentucky and Rep. Marjorie Taylor Greene of Georgia all weighed in on Twitter - and social media posts followed suit, blaming the outage on wind turbines and decrying the Green New Deal.

But, as we said, the bulk of the deficit in the energy supply was due to frozen infrastructure for natural gas, not wind.

"There is significantly more megawatts in that thermal unit category than in the renewable category," Dan Woodfin, senior director of system operations for the Electric Reliability Council of Texas, said of the outages at a Feb. 16 press briefing. ERCOT runs the grid that serves most of Texas, and the "thermal unit category" includes natural gas, coal and nuclear power.Indeed, data from the U.S. Energy Information Administration - see the adjacent EIA graph - show that in the early morning hours of Feb. 15, natural gas generation dropped 23% by 4 a.m., a total of about 10,000 megawatts on a system that was running about 65,000 megawatts in total at midnight. That morning ERCOT started rolling blackouts.

While the Texas energy supply includes a mixture of sources, the largest share comes from natural gas. More than 40% of the state's energy came from natural gas in 2020, according to a recent ERCOT report. The second largest share is wind, at 23%, then coal, at 18%.

So, it's true that wind plays a significant role in Texas' power supply - the state actually generates more wind energy than any other state in the nation - but there's no indication that wind energy was the primary cause of the power outages in Texas.

Data showing the amount of energy coming from each source over the course of a year indicate an inverse relationship between wind and natural gas - when one is up, often, the other is down. (See the adjacent EIA graph that shows electricity generation by sources over the last year.)

This happened on Feb. 8, just before the cold weather swept in - wind energy dipped and natural gas picked up. That trend generally continued, with natural gas increasing as temperatures across the state reached below freezing. Most households in Texas - 61% of them - have electric heat, compared with 40% nationally.

So, the frigid weather caused both a surge in demand for electricity and a decrease in supply of energy as infrastructure froze.

Frozen instruments at natural gas, coal and nuclear facilities, plus limited supplies of natural gas and problems with natural gas pressure, led to the outages, Woodfin reportedly explained earlier in the week.

"We've had some issues with pretty much every kind of generating capacity in the course of this multi-day event," he said.

I'm glad there is records of the power sources. If not they would never admit it.

QUOTE=the adjacent EIA graph - show that in the early morning hours of Feb. 15, natural gas generation dropped 23% by 4 a.m., a total of about 10,000 megawatts on a system that was running about 65,000 megawatts in total at midnight. That morning ERCOT started rolling blackouts.

Too funny. This article, like other vigorous attempts to defend wind power, might be renamed "Don't blame turbines for Texas crisis - they weren't generating enough power to be a problem!"
