The problem with renewables I have is that "what's good for the earth" and capitalism simply don't mix. Solar was fundamentally supposed to be almost-free electricity. You put a bunch of panels up and free energy from the nearest star. The stark reality though is that the people and institutions in control of solar equipment (this includes manufacturers, tariffs, etc.) reprice their stuff to match the price of the di…

How do you explain that solar got 50% less expensive in the last 10 years? Why would people and institutions in control of solar equipment reprice their stuff to match the price of dirty electricity? You think there is no competition? Or you confuse it with the system that has been put in place where the price of electricity in the grid is set up by the most expensive producer at the time (which does make sense altho…

But can it pay itself in a month or two? That's the bar. I cannot financially plan for even one year later. Too many unknowns.

A really good coffee machine that can do lattes costs maybe $200. If lattes at coffee shops cost $8 including stupid high CA taxes and the stupid puppy face guilt tips, it pays for itself after ~35 lattes including supply costs, or just over a month. That's the bar for pretty much anything.

Figure out how to sell me $500 in solar panels that generates $500 worth of electricity over the next month and make it tax deductible with no income limits. That is how you cover the country in clean energy. FAST. Until politicians can get their act together, slam the hammer and make exactly this happen, we're going to be on dirty electricity for a long time.

That should especially be the bar for clean energy. Clean energy shouldn't be a luxury for the wealthy.

We need something like this in the UK given the constant abundance of renewable energy.

We already do.

UK is up there in the world rankings for batteries.

I think they have slightly more grid batteries installed than California. UK have more people, but less money and less electricity used so I'd say they're doing better than California on battery deployment.

Just for a moment, try to imagine how much wind, solar and battery storage can be bought with the money required to build just one regular nuclear power plant (gigawatt output). The real thing delaying the energy transition is politics, we have the technology. And on a really small scale, here in NL we can build our own home battery storage systems with cheap 15kWh or 32kWh battery kits from China. Combine that with…

Nuclear isn't the enemy here.

Well first of all TFA is not talking about individuals buying solar or anything, so do we at least agree that renewables make sense for countries/state?

It seems like you have set an impossible bar for renewables so I don't know what to say to you. I do not think you'll be able to put a mini nuclear station, gas or coal one in your garden for less than the monthly electricity fee, so it's unclear to me what you are comparing it to.

The problem with giving money to individuals for their rooftop solar is that rooftop solar is not cost effective compared to large scale solar, if you really care about the planet and money is limited you should maximise the bang for your buck and help solar farms instead. But it's no secret that the current US administration is loudly anti-renewable and not keen on helping either of them.

This is a seriously impressive achievement. I wish there was a more comprehensive engineering deep dive, but I wasn't able to find one. So why is California's electricity the most expensive in the country?

California imports a third of its electricity, and that's expensive. It gets almost another third from natural gas. They've been changing rapidly from fossil fuels and nuclear to renewables and that's pretty capital intensive. And there have been some huge costs associated with the wildfires. There's a bit more technical info on California battery storage here: https://www.ess-news.com/2025/04/11/california-battery-d…

In general, imports are cheaper than the alternative, because if you have local gas plants that aren't maxed out, then you'd use those rather than pay more to import.

Some quick googling suggests this holds in California too.
