One nice thing about what’s happening is that politics are losing to reality. I’m not even sure how this became a left vs right issue in the first place (isn’t the right meant to be pro free market!?) but it doesn’t matter at this point anyway.

Eg. Texas is doing really well in renewable rollouts (see the amount of battery capacity they are putting in - https://www.houstonpublicmedia.org/articles/news/energy-envi...

It’s certainly not because of Texan politics either. It’s just cold hard reality. Renewables won’t be stopped at this point. Even the executive orders to halt wind farms don’t make a dent in what’s happening. We may end up a few years later than other nations but at least it’s unstoppable.

No, the right isn't meant to be pro free-market. It's meant to protect the interests, longevity, and demand-capture of its donor industries, primarily fossil fuels extraction, processing, and distribution, but increasingly large technology companies in monopoly positions in their markets.

All the "free-market" to "culture-war" rhetoric are just political/religious strategies to achieve that end.

one of the few good things Rick Perry did for TX was upgrade the grid so West Texas wind power can reach the main cities. Once West TX showed renewables could make a profit then there's not much anyone, left or right, could do to stop it. The lobbyists made sure of that.

Southwest Texas, where all the fracking took place, also turns out to be good for solar. It's very flat, sunny, and has pretty stable weather. I guess the grid is beefed up and accessible in that region because of the oil/gas industry, I've seen solar farms out there that are so big it's hard to describe. Imagine seeing a shimmering blue that looks like a lake on the desert horizon but then you get to it and it's just miles of solar panels. Again, the moment solar turned a profit there was no stopping it.

Yea I wonder how that battery capacity graph will look like post January 2026, since Texas's SB388 specifically excludes batteries from it's dispatchable power generation requirements. That doesn't necessarily prevent batteries storage from being constructed, but it does tilt the field pretty heavily in favor of natural gas.

It became left vs right because the interests of the rich have an easier time exploiting the right wing's vulnerability to fusion identity. The right wing is defined by a collective appreciation for hierarchies and conformity.

A lot of folks are spreading the message 'it's not right vs left but up vs down when in reality its both.

I've had so many arguments with people that think replacing a continual supply of gasoline with solar panels and batteries means that we are just as dependent on the source of solar panels as we are on the source of gasoline.

It's hard for people to visualize the massive shift here. It's the difference between needing to eat every single day, to merely needing to buy a 5-year supply and never having to worry about eating again until 5 years from now.

Except that it's 30+ years for solar panels, 20+ years for batteries.

The amount of independence and security that renewables-based energy infrastructure provides is hard to imagine for most people. The US's two big inflationary events in the past 50 years have been due to global fossil fuel supply shocks. And the second one that happened in the 2020s was when the US was a net exporter of energy! We still had exposure to inflation shocks because we had a global market for our energy sources.

Renewables change all that. Even if we bought all of our solar panels and batteries from China today, we'd have far better energy security, and have decades to build up the industry to replace them if we wanted to switch to autarky. (And autarky is a terrible idea, but that's a different discussion...)

You also get 30 years of efficiency improvements and 20 years of capacity and reliability improvements when you replace them.

>> "Each one of the new wind turbines will be capable of supplying more power to the national electricity grid than was generated by the entire Bellacorick wind farm."

epistasis an hour ago | parent | next [-]

It's funny, there was meme-like behavior a few years ago where anti-wind advocates would say "they're tearing down the wind farms before their end of life, like only 15 years in! Clearly wind doesn't work at all!"

And then you'd go and look at the details of any these "tear downs" and you find out that it's not because the current wind farm is failing, it's because turbine technology had improved so much that it made financial sense to drop in much bigger turbines right now, before their natural end of life.

Shortly after that, there started to be complaints about "what will we do with the waste from these massive wind turbine blades!?" as if they were in any way comparable in toxicity to the byproducts of fossil fuel extraction and burning.

It's so funny to see how shallow these anti-renewable talking points are. They all require that people spend zero effort and avoid critical thought in any way.

Well, in that case they’re also far bigger turbines (bigger than were available when the original project was built, granted).

Biggest take away - 90 million acres in the US go to corn/ethanol production. 31 acres of corn for ethanol to match the energy production of just 1 acre of solar panels. Revenue could be 3-4x that of corn production. Get ready for rise of the photon farmers.

That entire talk didn't once mention the phrase "energy density" which is the real reason we rely so heavily on hydrocarbons.

Additionally this talk makes the usual mistake of conflating "electricity" with "energy". While the US does have fairly high percentage of energy in the form of electricity it's still only around 33% of the US energy needs.

And still we see that "green energy" only supplements not replaces our other energy needs. We've seen tremendous EV adoption and yet US oil consumption is on an upward trend and nearing pre-pandemic highs [0].

It's wild that there are multiple, very serious global conflicts heating up over control of oil and people still believe we're just a few more years away from a purely green energy world with no evidence to suggest that's a remotely reasonable belief.

That's what happens when the "Leader of the Free World" is 79 with dementia with memories of the 1970s oil crisis.

We're not likely to get useful oil out of Venezuela, and any we do get isn't gonna be cost-competitive against solar.

irishcoffee 4 hours ago | parent [-]

Military vehicles that take oil-derived fuel take diesel, not hydrocarbons. The oil in Venezuela serves that purpose nicely.

No, I am not condoning anything here, just pointing something out.

ceejayoz 3 hours ago | parent [-]

There’s plenty of diesel available to us that doesn’t require stabilizing an authoritarian Central American nation and rebuilding their oil industry first.

telotortium 3 hours ago | parent | next [-]

I think Venezuela and Iran are more about restricting the oil to China in case of a conflict rather than providing energy for the US, although getting ahead of an anticipated demand increase from AI data centers is probably a contributing motivation.

ceejayoz 2 hours ago | parent [-]

I don't think interdicting Venezuelan oil in a US/China conflict would be too much of a challenge for the US, given... geography. It certainly doesn't require us to control the country or its oil industry.

I was responding to that bit. It isn't accurate.

I also said I don't condone it. Ignoring facts isn't helpful for anyone.

Edit for ratelimiting:

> You think it's likely that the US will manage to create a stable enough government in Venezuela for foreign investment to be successful? What in the history of American regime change efforts gives you this idea?

No. I was simply saying the oil is useful in the military-industrial complex, and it does have value. I've said this twice already. I cannot say if this value will be realized, and for the third time, I don't condone it.

> The gamble is a long game, with no guarantee of success. Returning Venezuela’s crude production to 3m barrels of oil a day would require 16 years of work and investment totalling $185bn (£137bn), according to figures from Rystad Energy, a global consultancy.

> At least $30-35bn of international capital would need to be committed in the next two to three years to make this scenario plausible, Rystad said. “This could only be financed by international oil companies, which will consider investments in Venezuela only if they have full confidence in the stability of the country’s systems and its investment climate for international oil and gas players,” it added.

For planes. For no other major use of hydrocarbons is it the primary concern.

Transatlantic shipping also. Planes require highly refined fuel though, while ships can burn most anything flammable, even really crappy biofuels. Hardly anything is worse than heavy fuel oil.

Yeah I watched this a week or so ago and had a similar issue.

I'm super optimistic about green energy and in favor of expanding it.

But also acutely aware it's barely putting a dent on energy use despite year-on-year record levels of capacity install (>90% of new capacity is green), which far exceeds expert expectations every single year. Non-renewables keep growing, forecasts and ambitions were cut by the Trump admin, and it is expected that the latest economic revolution's (AI) main bottleneck is going to be energy by the end of the year.

We have essentially blown past the paris accord thresholds (we've seen months of +1.5c temperature, which was the limit we envisioned in 2015) and despite renewables far exceeding expectations, they completely fell short of what is necessary pre-2023. Post-2023 you have Trump derailing renewables wherever he can and AI increasing demand even further.

It really looks pretty hopeless and frankly it's sad that there is no real conversation about this, which seems to be an existential question for the generation living in 2100 and beyond.

You're also now getting to the point that adding new capacity is increasing the amount of renewable energy that is being curtailed (i.e. thrown away), meaning while renewables get cheaper over time, the rate of things getting cheaper will slow down as renewables must be increasingly paired with storage investments (which are also getting cheaper but introduce additional cost).

For example, sunny Cyprus curtailed 13%, 29% and 49% (!!) of its solar generation in 2023 to 2025 respectively. Yes last year half of the solar power that was produced, was thrown away, because of a lack of demand-supply balancing. Cyprus is uniquely poorly positioned (high solar potential, small country with a single small timezone, no interconnectors to offload surplus to other countries, no storage facilities etc) but it's still a sign of things to come. Further generation will increasingly need to be paired with significant storage, or it's partially wasted.

He talks about transport and heating

That doesn't leave much left when you look at the energy flow once you remove domestic, commercial and transportation usage and replace it with electricity. A tiny amount left for plane s(and reducing per flight as planes get more efficent and battery planes start coming to market), and industrial gas usage.
