This probably depends a lot on how close you are to the equator. Here in Germany output of solar in winter is negligible, and if there is no wind, which can happen for several consecutive weeks, we need a backup. No utilities company will build a fossil power plant that will be used only a few weeks per year, so our government will have to step in to make sure this happens. On top of this you have very high costs for…

Here are some numbers: January 2025, the output of solar was ~1500 GWh, it peaked in June at 10500 GWh. So the lowest output was about 15% of the maximum, this year. https://www.energy-charts.info/charts/energy/chart.htm?l=en&... https://www.energy-charts.info/charts/energy/chart.htm?l=en&... Looking at wind, the ratio between min and max per week is about 1:5 (~1200 vs ~6000 GWh). Just as there is always some solar…

> it peaked in June at 10500 GWh

And 8280 GWh the previous June for those wondering roughly how much of this was due to more solar panels being deployed.

Batteries are probably going to kill long-range transmission lines and open up remote generation at a scale never thought possible. Desert solar, remote hydro, etc etc. As the price continues to fall and the density continues to rise the economics of transmission completely change and will decouple the location of power generation from the use of that power dramatically. This decoupling of location and use will drast…

I think long range transmission remains a thing anywhere having a local grid remains a thing (which will be most places for other reasons).

Load-balancing the area having a cloudy few days and the area having a sunny days and the area having a windy few days and so on will remain extremely valuable. It lets you install a lot less batteries and isn't that much infrastructure given that the last mile problems are dealt with already.

The scaling up of battery manufacturing for EVs and now solar storage has lead to prices I would have never imagined I'd see in my lifetime. It's one of the success stories that, having lived through it, has been a real joy. I know that folks might have been able to point to a graph years ago and said we'd be here eventually, but I had my doubts given the scale required and hacking through all the lobbying efforts we…

You are certainly not alone in your beliefs, but it always amazes me which technologies get the benefit of doubt and which are severely penalized by unfounded doubt. Solar and especially batteries are completely penalized and doubted in a way that defies any honest assessment of reality. The EIA and IEA forecasts are as terrible as they are because the reflect this unrealistic doubt (random blog spam link, but this observation is so old that it's hard to find the higher quality initial graphs)

https://optimisticstorm.com/iea-forecasts-wrong-again/

Similarly, nuclear power gets way too much benefit of the doubt, which should simply vanish after a small amount of due diligence on construction costs over its history. It's very complex, expensive, high labor, and has none of the traits that let it get cheaper as it scales.

Has any production battery become cheaper than LEAC ACID for computer UPS ? I have not seen new cheaper UPS getting launched.

Problem with Lithium ones is that they tend to be quite flammable. Lead acid is mostly inert I believe?

The acid in lead acid is sulfuric acid and if overcharged vents hydrogen gas, thats why they need a ventilated space typically. Sealed lead acid have safety vents that might pop if enough pressure builds.

They are most certainly not inert, they just have well established safety and charging protocols and are not used in very high quantities together because of their low energy density and cycle life.

LFP batteries which have iron phosphate cathodes are very stable compared to colbalt based batteries that tend to have catastrophic failures due to overcharge causing cathode failure. LFP have higher cycle life and are cheaper and typically whats used for storage and application where the loss in erergy density is not a big deal.

It's already cheaper to demolish an existing coal plant that's already paid for and replace it with solar + battery. Solar and battery brand new buildout, plus their maintenance overhead, dominates coal even when you only count coal's maintenance cost. People have it in their heads that this is some bleeding heart, don't ruin the planet thing, but it's plain economics. Non-renewable energy is simply inferior, and wil…

Sure, and none of that amounts to even close to the damage from stripping vast areas of the earth to dig up coal, grinding and transporting it to power plants, then setting it on fire, and releasing tons of CO2, and then disposing of tons of unburnt waste full of NASTY chemicals.

And having to do all that continuously, every day, for the life of the plant.

In every single solution you can point out problems. Complaining that "X isn't perfect" is the easiest and laziest thing in the world to do. Assessing the ACTUAL costs and damages IN PROPORTION is more difficult, but actually yields good results.

I don’t care if German prices for electricity are below inflation. They’re just still expensive. As an EV owner is difficult to find an electricity provider with costs below 0,25€/kWh, and most of them go beyond 0,30€. While I had prices in other European countries for around 0,05€/kWh at night for example. Not only that, Conservatives, Socialists and the Green all managed to increase our electricity CO2 footprint by…

That’s mainly because German has fucked up the smart meter rollout. In their wisdom they separated the meter and the gateway when other countries just combined it. They also made it super secure (good), but then didn’t look at the fact that lots of people live in rented apartments and their meters in the cellars have really poor or no cellular connectivity. When Germany can finally do steerable dynamic loads properly…

"If there’s anything about the Germans you can count on, is that they move slowly."

What happened to Blitzkrieg?

As opposed to coal that pump out NASTY chemicals right now?

Weirdly, none of the many phones, tablets and laptops I've owned have ever caught on fire. I guess I've just been lucky.

It’s not as much about the risk of failure, as both are safe when the correct safety measures are in place.

But what might happen when they fail - thermal runaway is no joke with lithium-ion, ask any firefighter.

One of the few problem of nuclear is summer time water use. Combining solar with nuclear would be the best option in my opinion.

Nuclear plants, like most large thermal plants, are almost always located near large bodies of water and return that water downstream so it doesn't really matter?

It matters if people don't want to see the rivers full of dead fish, so last year there were already shutdowns because of heatwaves.
