I just upgraded the solar system at my family's off-grid cabin. It's incredible how much battery technology has improved over the last 10 years. Everyone is getting tired of me checking the panel to see how many watts we're bringing in. Next project, install a shunt and get a Raspberry Pi talking to it over USB. And then I'll be able to build a Grafana dashboard. :)

Indeed. Steel mills, aluminum smelters and glass factories really adore the intermittent nature of renewables.
Smelters in Australia are leaning on the fossil-friendly politicians to stop getting in the way of renewables because they can't compete with global prices unless they use renewables.
Incredible gobsmacking amount of stored energy on display here. Great to see. https://bsky.app/profile/neilgrant.bsky.social/post/3mneo3to...

It’s already irreversible, but it’s just disappointing to see how the U.S. administration has chosen to actively fight against it, while other countries like China are embracing reality. It’s actually funny if you don’t think about it too hard. The U.S. president is trying to make us more reliant on fossil fuels, while starting a war in Iran that’s led to the global fossil fuel market to be negatively impacted, forci…
> the U.S. administration has chosen to actively fight against it the biggest producer of renewables is Texas, by a longshot. and the state of california just created insane NEM laws that favor the pockets of pg&e (and are shit for the environment) and as a result solar home installations have cratered.

it depends. some places it makes sense, some places it doesn't. it will be adopted when the money speaks. the good news is that money is a reasonably close proxy to "environmental benefit" (balancing the environmental costs of green infra production versus dirtiness of gas generation)
> some places it doesn't I can see this for wind, but not solar. PV turns sunlight into electrical energy. The whole damp rock gets sunlight on the outside, why not build panels anywhere? For wind yeah, if you live one of those boring flat places which gets tornadoes a wind turbine is definitely a bad idea, it won't make much energy and then a tornado turns it into scrap and possibly destroys nearby things with chunk…
Solar works a bit better when consumption patterns is the opposite, and the output is more reliable.
I know some people who are adamantly against solar and wind (personally I like both but I can see some shortcomings - for example I have heard that ai datacenters are using gas at times because of its flexibility) So what are some of the best talking points to "sell" solar and wind to the unconvinced? Or will they just adopt it once it's seen everywhere?

If people have strong opinions about renewable energy, just don't waste your breath. You can't reason someone out of an opinion they arrived at unreasonably.
- Using old data - the price of renewables and storage technology have fallen through the floor but bad actors are quite happy to use outdated numbers to convince you that they're not cheap
- Ignoring existing downsides - renewables have issues and we shouldn't forget that, but it's easy to forget what we're replacing. e.g. Lithium mines are environmentally unfriendly, but you dig it out of the ground and turn it into a battery once (and bonus - it's recyclable). Oil and gas must be continually dug out of the ground and burned
- But China... - I don't think most people realise quite how quickly the rest of the world is pushing on with renewables

The money men have no moral attachment to any source so given how cheap this mix has gotten it basically wins.
* I'd point out without China and its Leninist command economy (as well as publicly funded research) getting the price of these technologies down to where it is now we'd still be doomed, but we are where we are so now the system necessarily will act in its own self interest to use the basically free energy. Is it going to be enough at this stage? Who knows, but I see reasons to be optimistic.
One of the short-term issues in the US is going to be that a lot of utilities depend on natural gas and natural gas prices are going to keep rising beyond whatever happens in the Persian Gulf because of increased LNG exports (that directly raises domestic prices) and the increased use of gas turbines for AI data centers. Plus all the consumers are going to pay for the infrastructure buildout for electricity for those data centers.
So, despite a large Y/Y solar increase in the US, electricity prices are only going up.
