Sorry but you can't have EVs everywhere, WA and CA banning natural gas for heat and cooking, WA and OR sabotaging hydro plant output for salmon habitat restoration, while shutting down your most reliable sources of power. The math does not add up.
Solar and wind output is not constant or reliable. NIMBYs sabotaged nuclear years ago. It takes how many years to bring a new plant online?
A lot of feel-good rules and regs were passed, pushing a massive shift to electric power, with no consideration as to where the additional power would come from.
You can't wave your arms like a Peanuts cartoon and have all that extra power appear, which is the logic that was used in passing many of these impractical regulations.
> the math doesn’t add up
There’s no way for you to know that. You don’t do the math. People like me, who work in the clean energy industry, do the math. The math works fine. You should try working as hard as the math does, instead of complaining.

Have a closer look at the hydro dams that have been removed for salmon habitat.
From what I've seen capacity was tens of MegaWatts [1] and some were just for irrigation. Meanwhile, large dams [2] are doing gigawatts.
Large dams also have negative environmental effects and maybe one day they'll get removed too, but accepting the tradeoff for large amounts of power makes more sense than destroying samon fishing to get irrigation water or a piddly amount of power.
Especially at a time when electrical power use was trending down due to efficiency gains and offshoring manufacturing, and samon fisheries were in danger of failing, it made sense to remove dams that weren't terribly productive. And start considering actually doing the work to make the larger dams fish friendly, eventually.

Solar and wind is extremely reliable. What isn’t reliable is deployment of it.
Energy storage is required along with solar farms.
Until the sun goes down at night or the wind stops blowing. You ignored the word "output".
> Energy storage is required along with solar farms
How many batteries are we going to need for that? They literally just figured out how to get the child slaves in the Congo out of the supply chain with a shift to LFP.
There are technologies for battery storage that don't look like batteries. Thermal energy storage is an example. It consists of heating something very big that holds a lot of heat and releases it slowly, then using that stored heat to generate electricity while it cools down. This isn't suitable for home use, but at the city scale, or larger, it's quite efficient:

Enough to store the energy between gaps, plus a buffer?
Batteries aren't exactly made from gold. Grid scale batteries especially, where weight and size doesn't matter as much, are totally viable on a mass scale.
Fear really IS the mindkiller! Stop being afraid and start educating yourself. You are on HN, you are supposed to be smart.

Fox brain alert!
We have batteries for this. See Texas and California.
This gets tiring. No, china has no electricity problem in the night and their share of solar is off the roof.
What an opinion to have when thus far evidence has concluded the opposite. Just because funding for the infrastructure keeps getting derailed, delayed and lied about by bad actors doesn’t make the anti-renewable parrots correct. There are situations where —at minimum- hybrid solutions are far more viable options but for many locations just those two solutions work very well.

Speaking of infrastructure, how about pushing a mass rollout of EVs before giving a single consideration as to where the charging infra would come from?
Charging infra would only exist if there's demand for it, if you have a better solution for this catch-22 I'm all ears.
Though it looks like rolling out EVs before the charging network existed worked, there are thousands upon thousands of chargers now that there are enough vehicles to use them.
That seems like a pretty bad example considering the rising popularity of EVs has coincided with an enormous grown in available charging infrastructure to service the EV customer base. It's almost like human society can handle complex, interdependent systems as they change, either through deliberate organization or natural market incentives.
It's not like the current mix of electrical generation and fossil fuel distribution is some naturally occurring phenomenon or alien technology. It's an enormously complex and interdependent system we built. I'm pretty confident we can build new and different things.
