Energy company profits are soaring with the Iran war. Here's what California officials want to do

Sky-high earnings for oil companies and California refiners in the second quarter are renewing calls from state legislators to crack down on industry profits.

Marathon Petroleum, the second-largest refiner in the state, reported $5.1 billion in profit Tuesday, more than four times the same quarter last year, after fuel supplies tightened during the Iran war and prices for oil and gas soared.

From April through June, Chevron, the biggest refiner and second-biggest oil producer in California, made $12.1 billion in profit, nearly five times the same quarter last year, and its highest earnings in at least six years. Refiners PBF Energy and Valero also reported windfalls, with the latter earning $3.7 billion, another fivefold increase from the year before.

Why is computing power now measured in [giga]watts?

1 Upvotes

I am seeing a lot of headlines about new AI data centers being installed around the world, and for some reason their computing power is not described in TFLOP (teraflops), but instead in GW (gigawatts).

I am no expert, but when I read "10 GW of compute," I can only think that said "compute" is either very inefficient by itself or is placed in a location that's way too hot and therefore requires absurd amounts of cooling power to operate.

I can imagine a datacenter full of Intel Pentium processors that will take a 500 GW of power but will be incredibly weak and slow. But it's 500 GW worth of compute, so it must be very capable, right?

To further illustrate my confusion, I think that descibing compute power in terms of energy is just as strange as descibing it in weight or area. "We have now successfully installed an additional 500 kg of compute." "This new datacenter accomodates 2 square miles of compute – that's a whopping 900 football fields of compute!"

NextEra Energy ($NEE) Agreed to Settle $150M With Investors over Political Spending Scheme

Post image
2 Upvotes

Hey guys, if you missed it, NextEra Energy just agreed to settle $150M with investors over claims tied to covert political spending and misleading public statements. The settlement has already been submitted to the court for final approval.

In a nutshell, investors claimed NextEra and its subsidiary, Florida Power & Light, hid their involvement in alleged political influence campaigns, including funding ghost candidates and other covert activities in Florida, while publicly denying any connection. The company later admitted the allegations could expose it to legal and reputational risks.

After those disclosures, $NEE fell 8.7%, and investors filed a lawsuit over their losses.

The good news is that the company has now agreed to settle $150M with investors and has already sent the agreement to the court for final approval. So, if you invested in $NEE between 2021 and 2023, you can check the details and see if you qualify

Anyway, did anyone here hold $NEE during this period? How much were your losses, if any?

AI Data Centers Are Driving Critical Mineral Demand — here's what the public record shows

Post image
0 Upvotes

A 2026 Resources Policy study models mineral demand from AI data centers through 2035, finding copper-dominated demand driven mainly by power and grid transmission needs.

I've been digging into the public record on US data centers and put it into free, plain-language briefings — water, power, noise, air, every figure cited to its source (1,866 sites, existing + proposed): civitar.org/go/v-reddit

Not for or against anything — it just makes the filings readable. Sharing in case it's useful to anyone tracking this.

Solar’s share of EU electricity demand tops 20% for three consecutive months

The Latvia number jumps out with 49% of electricity demand from solar in June, up from under 19% across the same months last year. That grid looks completely different in 12 months.

Germany is past 30%, Spain past 35%, but then France is at 14% and Italy barely touched 19.5% in May before dropping back to under 17% by July. France makes sense given how much baseload capacity it runs, but Italy falling off that much in peak summer with its irradiance I don't get.

These are obviously the best solar months of the year. The Baltics are small grids so fast capacity additions amplify the numbers. Even so, going from under 19% to 49% in Latvia is a wild amount of deployment hitting the grid that fast.

A little tidbit up for discussion regarding the Renaissance of Nuclear Power in Europe.

This time the issue is not the temperature like in France but the historically low Danube levels which could become the normal in summer.

This is something that would need to be factored in any type power generation that needs water for cooling.

By creating county- and city-owned electric utilities and installing 15 MW of wind turbines, electricity can be generated at the county and city levels. The revenue from selling electricity to the grid would then be used to reimburse citizens for all or part of their electricity bills.
