Solar is only half the battle though. There can often be a severe electricity shortage in the evening when solar power shuts off but temperates are still high. This issue is greatest in the late summer and fall because it’s still very hot but the sun sets earlier.
There are solutions to this issue but they are fairly early in development and sometimes expensive. California is struggling with this issue currently. We’ve installed a huge amount of battery power over the last few years which has prevented several catastrophes so far but heat continues to get more severe, increasing energy needs as we are trying to shut down the state’s remaining gas peaker plants.
The Texas grid issues have been right after solar drops off (evening, not day) because Texas does rely on solar for a small, but necessary, part of it energy. The second half is energy storage, and Texas lacks that which is why its been having many close calls this summer and has resorted to paying cryptominers to not mine to narrowly scrape by after solar power drops off.
Texas can use up to 100GW of power and was basically always over 60GW during that time of day this summer. The 3GW was used on a few days to bridge the gap, but wasn't quite enough on its own on other days. 10GW more would have covered this summer though. Hopefully next summer isn't worse though (seems like expectations is next year is supposed to be hotter). Population also continues to grow and electrification continues. And NG makes up the bulk of the power still. Hopefully wind and solar installations grow significantly in the next year as well.
Not to mention Diablo Canyon. Last I heard, we were working on an expansion at Long Valley Geothermal station, but it won’t be ready before DCNR goes offline.
It’s 2018 and California has postponed the closure of DCNR. It’s 2020 and California has postponed the closure of DCNR. It’s 2023 and California has postponed the closure of DCNR. In the time we’ve been kicking the can down the road, we could have built a newer, better, safer nuclear power plant to replace DCNR. Instead, we keep pushing DCNR way past its intended service life, and we’re going to be shocked, shocked I tell you, when something finally cocks up.

That’s true of household panels (which are great for offsetting your daytime usage, which is usually your highest usage), but that is generally not true of large solar installations that heat up a huge mass of salt until it’s molten and then produce power from that source 24/7. Example: insideclimatenews.org/…/csp-concentrated-solar-mo…
TL/DR: large solar installations produce power 24/7 (yes, even when it’s dark)
I saw something recently which is the same principle as molten salt, except the medium never melts, is stable, and… iirc is pretty much just carbon. I was trying to look for a source and all I could find was the equally-encouraging news that the humble red brick has now been turned into a capacitor (with a wall of bricks being able to perform as a supercapacitor)
Solar thermal isn’t really what we mean when we say solar power. The vast majority, even at utility scale, is PV panels just like the ones on your roof. Historically, solar thermal was too expensive and PV panels are still far cheaper.
That said, for areas like CA that may soon approach maximum solar penetration it may deserve a second look because of its more consistent energy output. It will mainly be competing with batteries, pumped hydro, and new generations of geothermal technology. All of these are new and fairly unproven at scale so we’ll have to learn as we go which is the best option for the later stages of decarbonizing the electrical grid.
Geothermals been proven since the 60s. It’s a sealed system, there’s no pollution (even if the pipe popped, it’s just water), stations can be planted next to preschools and daycares and no one would be the wiser.
If your state has mountains, geothermals prob the answer. If your state doesn’t have mountains (Kansas, Florida, Delaware), being from Washington, I don’t know how you guys can live there. Not being able to orientate by the horizon fucking weirds me out. Especially in fucking Florida. I was driving thru the Ocala “forest” and it’s all Spanish moss and saw palmettos everywhere. You can’t see more than 10ft into the forest, and that’s when I noticed you can’t see the sky thru it either. It’s just barely slivers of rays making it to the floor. I’ve never felt so claustrophobic in my life. *shudder fuck florida
I didn’t mean geothermal was entirely new but traditionally it has been limited to very specific geologic conditions which have largely already been developed. Newer technology (ironically pioneered by oil and gas drilling) has recently made many more sites possibly economical. But as with the other things I listed, these new types of geothermal plants are still somewhat unproven and expensive. I know they’re being investigated but so far very few have been built.
I fail to see the problem. You cool your house down while the sun is up and even if it is still hot outside, then your house gets a bit warmer, so what? Still it is comfy inside and in the night you can open everything up to get some fresh wind in.
This is what I do, but there are still problems. Some people are at work and don’t have programmable thermostats. If you have a poorly insulated house, even if you do pre-cool in the middle of the day, by the time late evening rolls around, it can be getting quite hot again. And during extreme heat waves, the overnight temperature can remain very high. Last night I went to open my windows around 10 PM but it was still hotter outside than in my house. And yesterday wasn’t even particularly hot where I live, the high was only in the low 90’s.
okay, i didnt think it this bad. i thought it should cool down quite quickly at night because half of the state is a dessert, but i now realize most of the people life in the subtropical part.
Even in the desert it can be an issue. Phoenix had an overnight low of 97 this summer. Soon that may be commonplace.
Part of the problem is poor planning by utilities but our systems are also being tested by weather that is truly unprecedented in human history. Our grid, and our strategies for keeping cool were developed in a different climate than the one we now inhabit.
My Texan ass was confused because the last week has been the most pleasant weather we’ve had in months. The I looked at the article and saw it’s from 2017. Don’t get me wrong our state is fucking dumb all of the time, but I assure you we are not experiencing a heat wave. It’s been unseasonably cool.
I stand corrected. But it’s not so hot now. Also it wasn’t a heat wave, it’s just Texas summer. Which is why there’s no excuse for ercot to be so fucking unprepared.
People will soon be living in Texas no power year around when they throttle you and charge you thousands for power every month of the year because either A) ITsSS TWOooh HAaAWwTT or B) TtThEEee GGRiiIdD IIsSSnnTT Winterized. What a joke
Aaahhh, the free market economy at work without limits, without government planning, regulations, or interference.
Government regulations bad! It means we can’t squeeze our customers, we can’t fuck up on an hourly basis, we can’t be dicks!
And in before the commies start… No. Bad dog! Get out with your “we need to become Communist hippie communes!” comments, please
We need to put reasonable rules and limits to a capitalist system. Regulate big companies, regulate infrastructure, tax the rich, use the money for social platforms
In all fairness, Texas has an incredibly weird, idealistic, view of the value of market forces and their government utterly fails in its job as a result.
It’s not just power lines. It’s everything. They distort their market on ideological lines and then assume that’s the best case.
I’m with the commies on this one. We need to nationalize utilities like energy distribution. No reason to have a profit seeking entity in charge of necessities like electricity.
In sane parts of the US, utility companies are technically private entities, but they’re related so much they pretty much operate like government agencies.
Take a look at how the Georgia Public Service Commission is regulating the finances of the new nuclear reactors (Plant Vogtle 3 and 4) and then try to keep a straight face and tell me it’s working.
The big difference being a drive toward profit. Nationalizing energy production and distribution would be a slam dunk for everyone except the people at the top of these energy companies and their shareholders.
Actually, pretty well 99.9% of the time. And if a few people die here or there in a freeze or heatwave, well they shoulda use some of those electricity savings on a generator or something.
^ How the conservatives in Texas feel about the situation
I moved to the PNW as well. I hate the bureaucracy, and miss the barbecue, but they can have the rest. The bureaucracy you have to tolerate because it helps maintain the balance of divided people making the best choices. Much better path than down south where the road to hell is paved with red intentions.
Idk about the bureaucracy being useful, maybe it just needs tuning. But rn Portland (or maybe it’s the county) has $10million set aside for homeless services/projects and no plan for any of it.
Sure they do, then they get run the fuck over by the big money Capitalists who are building it anyway. Texas is #1 in renewable energy production for a reason.
They do, but capitalism is gonna win this one. Solar is cheap and sunshine is plentiful so it is still getting built. ERCOT is a disaster, most of it on purpose but the legislation that set it up.
Would probably be a good idea to hook up to the neighboring power grids too for emergencies… like every day in the summer is turning in to.
Many Texas leaders (and other Taxans) see any energy source that’s not oil and gas based as “part of the radical liberal agenda.”
Solar energy is also decentralized, so people/villages can have their own source of energy and the profits won’t go to one monopoly and that can’t happen, because free market - yes - but not actual free like this.
Quick question, how do I get solar installed (in Texas) without getting scammed. Every company I have talked too has felt like dealing with the slimmest used car salesman.
I think you run into this problem anywhere in the country. We were recommended our solar company by our neighbor, who had a good experience. They finally finished our job, and mechanically, they did a fine job. But their interpersonal interactions were mostly bad, and my wife would vehemently not recommend them to anyone else. Seems like it’s going to be a crapshoot. Good luck
The problem is ideology. The Texas power grid is the end state of neo-liberalism taken to the extreme.
The belief that natural monopolies should be privately controlled with minimum regulations has lead to this. A power grid run for maximum short term profit with minimum investment. The grids poorly maintained, because that doesn’t make money. The grid is unfit, because implementing designs that cover the extremes is expensive. The price is excessive because the state is ideologically unwilling to intervene.
Look, this is super misleading information and I keep seeing it repeated. They’re first in the nation in total electricity generation from renewable sources, but that’s mainly because of how big they are. If you look at what percentage of their consumption is from renewable sources, they’re not even in the top ten.
The reason Texas is #1 in renewables is actually Rick Perry, bless his heart. He pushed for a massive expansion of wind generation capacity back in the early 00s and was instrumental in building high voltage transmission lines between west Texas wind and the more eastern population centers. He would be drummed out of today’s Republican party
Which is why he became Secretary of Energy under Trump. Also I think he was kicked off Dancing with the Stars in one of the early rounds. Certainly makes him qualified to occupy the same chair as Steven Chu.
