How solar and wind energy are saving Texans from a record heatwave
The same sun that is scorching Texas is keeping the air conditioning running, no matter what certain Lone Star legislators say
JULY 4, 2023
Texas has been breaking all sorts of records, and that's mostly bad news.
As a heat dome settled over Texas in June, trapping brutal heat and humidity underneath, high temperature records were broken across the state. It was so hot in Texas, meteorologist Ben Noll noted, that the only rivals on planet Earth were "the Sahara Desert and Persian Gulf area." The National Weather Service in Houston apologized for the "potentially deadly" and "oppressive and persistent heat" smothering the state: "Sorry, y'all. We're gonna get back to our typical levels of heat someday, but not real soon. Keep up the fight against the heat!"

Texans, obviously, cranked up the air conditioning. And that was largely responsible for a new all-time record for energy demand in the state 80,878 megawatts on June 27 though the state's grid operator, the Electric Reliability Council of Texas (ERCOT), didn't expect that record to hold long.
The Texas power grid which, uniquely, only serves Texas has shuddered and occasionally broken in recent years under the weight of extreme weather, a growing population and aging infrastructure. But so far, the grid has held up this summer. In fact, ERCOT has only asked customers to voluntarily reduce electricity use once during the heat wave.

And that's due in large part to another record Texas has shattered this summer: Solar and wind farms set a new high water mark for renewable energy generation 31,468 megawatts on June 28, helping offset the 8,000 megawatts knocked offline at ailing natural gas and coal-fired plants. "Wind and solar are giving us a big enough buffer that even when we have a handful of power plants go offline, it isn't causing disruptions," Dan Cohan at Rice University in Houston told The Washington Post.

(14,559 posts)In the 4 billing cycles since then I have purchased $0 is electricity in three of them. In fact I have contributed ~600KwH to the grid, enough to run my own home for a month. According to the software that comes with the system I have generated 3.1 MWh, reduced carbon by 2.2 tons which is equivalent to 36 trees which makes up for the asshole next door that cut two 100 year old Oaks down because he didn't like the leaves in the fall.
The cost of paying for the panels ($20k over 20 years) after paying down the principal with Biden's tax credits will be about 15% less than what I spent last year. Unless of course the rate increases as it is sure to do here in unregulated Texas in which case it will be better.
I had been skeptical of the solar pitches for years but if your home is suitable (roof faces South, no trees obstructing the sun etc) you might consider it.
Be sure you're dealing with a stable and established company (warranties don't mean shit if the company goes belly up) and just assume you'll break even on electric bills. You may be pleasantly surprised as I have.

Some of the statistics have changed for the worse. In the past thirty days 49.75% of their electricity came from gas, up from the 43% in the previous post.
Hah, the good news is we're only going to amputate one of your legs, not two!
Solar and wind are no threat to the natural gas industry. They will, in fact, only prolong our use of natural gas.
The natural gas industry knows this and approves.
Think. Again.
(8,187 posts)...because alternatives have not completely displaced gas YET, we should stop using them?
Hah, the good news is we've fully replaced one of your amputated legs, and we're working on replacing the second!

(4,168 posts)Solar & wind are simply adding more capacity to growing energy demands. By all means keep using them, but don't fool yourself that this is going to turn climate change around.
Think. Again.
(8,187 posts)We haven't yet built anywhere near enough solar, wind, or nuclear.
As you say, the additional capacity from new-built non-CO2 energy sources is barely keeping up with increased demand.
Obviously a reduction of consumption would help tremendously but this discussion is about the amount of non-CO2 energy we are generating and I think anyone would agree that so far it is not anywhere near enough.
Much more renewable energy needs to be built out quickly.

(4,168 posts)Excess energy will be used for ever-expanding 'needs.'. The best we can say -- given current patterns of human behavior and usage -- is that Green tech is less damaging than fossil fuels, but this is still the entirely wrong paradigm.
Until we focus on decreasing demand for energy and dropping oil as an energy, not supplementing oil energy, we are not making progress. We are still driving ourselves over a cliff.
Think. Again.
(8,187 posts)We must 'drop oil as an energy', that's very clear.
And I agree, our consumption of energy must decrease, AND we must replace what energy we do use with 'green tech' because it is less damaging.
I read somewhere that we have about 50 years of oil left, not counting growth of consumption https://www.worldometers.info/oil/
So, yes, we will stop using oil soon, and we can either continue to massively increase 'green tech' to support whatever energy needs it can, or not.
Think. Again.
(8,187 posts)I don't think anyone has figured out how to turn climate change around.
But I believe we should be doing everyhing we can to decrease the amount of damage that will result from additional CO2 emissions.

(8,678 posts)Are you a nuclear lover? That's not going to happen in our lifetime.
Random Boomer
(4,168 posts)Unfortunately that runs counter to human nature (and animal nature). Our impulse is to use more, not less, when there is ample supply, consequences be dammed.
honest.abe
(8,678 posts)More likely its just going to increase.
Im afraid its going to take a massive catastrophe to get everyone's attention.

(1,091 posts)The first and most obvious is population growth
The second is that one thing renewable energy does in impoverished countries is bring electricity to populations that don't have it which of course increased demand...
Think. Again.
(8,187 posts)...but I don't see that happening in our lifetime.
And although I have no emotional attachment to nuclear, it does offer yet another method of producing some needed energy, but at the very high price of the risk of radiation releases and the challenges of safely (?) storing continually increasing amounts of radioactive waste.

(33,525 posts)20 minutes of record power in an unreliable system is "saving Texas?"
When the wind doesn't blow, and the power demand peaks in the early evening, to they turn off the air conditioning, or do they burn dangerous natural gas and dump the waste directly in the planetary atmosphere, driving the need for power because the solar and wind fantasy has done nothing, zero, to address climate change.
This announcement is rather like Trump announcing he won the election, delusional.
There are record temperatures all over the planet, which is burning, because people think that brief so called "renewable records" matter and shut off their minds when this unreliable, temporary crap isn't doing a damned thing.
Here's the fuel mix as of this hour on the ERCOT grid:
One would need to be as insane as Marjorie Taylor Greene to declare burning coal and gas for more than half the power in the State is a "victory."
It isn't. It's a grotesque failure, an obscene failure.
Today's demand peak in Texas is predicted at 82,587 MW at 15:30 CST (5:30 PM CST). It's still over 80,000 MW at 19:35.
Every wind turbine in Texas will be waste within the next 25 years, as will every solar cell. Today's toddlers' generation will face, before they reach the age of 25, the waste all this crap will be with a further destroyed atmosphere, depleted mineral resources, extreme temperatures and possibly famines, worse droughts, worse fires.
Why?
Because we live in a time when grotesque failures are declared successes.
Texas should have built nuclear reactors on the Gulf; and they should still do that, perhaps high temperature reactors to reform, with supercritical desalination, the water badly damaged by the Deepwater Horizon disaster that took place while everyone on the planet was cheering for solar and wind, which killed, instantly, 10 people more people than died from radiation at the big bogeyman at Fukushima, although Deepwater Horizon killed more people than Fukushima, and promptly went down the memory hole.
In fact, if they sucked some of the eutrophic waters caused by "renewable ethanol" in, they could capture carbon and perhaps restore the now dead oyster beds.
History will not forgive us.
Think. Again.
(8,187 posts)By storing energy during peak production periods and using it as needed at other times, they were able to keep the grid powered.
And as your graphic of the Ercot grid generation clearly shows, a huge chunk of the energy needed is now being supplied by non-CO2 sources.
As we continue to build more non-CO2 sources, we will displace even more coal and gas.
It's working!
But as you so clearly showed us, we need to build lots more non-CO2 sources, quickly!
