California Exceeds 100% of Energy Demand With Renewables Over a Record 45 Days (electrek.co) 155
An anonymous reader quotes a report from Electrek: In a major clean energy benchmark, wind, solar, and hydro exceeded 100% of demand on California's main grid for 69 of the past 75 days. Stanford University professor of civil and environmental engineering Mark Z. Jacobson continues to track California's renewables performance – and it's still exciting. In an update today on Twitter (X), Jacobson reports that California has now exceeded 100% of energy demand with renewables over a record 45 days straight, and 69 out of 75. [...]
Jacobson predicted on April 4 that California will entirely be on renewables and battery storage 24/7 by 2035. California passed a law that commits to achieving 100% net zero electricity by 2045. Will it beat that goal by a decade? We hope so. It's going to be exciting to watch. Further reading: California Exceeds 100% of Energy Demand With Renewables Over a Record 30 Days

Here is Finland we have had net metering on hourly level, but we are now moving to 15 minutes' intervals.

Fourth: Those of us actually entrenched in the California sustainability industry though are trying to tell everyone that:
1. We do not have enough energy supply to power a 100% EV California.
2. We do not have a sufficiently modern grid to transport the massively increased energy from generation to panel **particularly** in light of increasing mandates to transition residences away from natural gas appliances to electric. The two goals work against each other.
3. We do not have sufficient EV charging ports (public or private). Part of that is because a successful business model is yet to emerge.
4. Multi-unit dwellings (apartments, etc.) are insufficiently incentivized, mandated, and/or capable of serving a 100% EV residential population. Rentals make up 44% of California's housing inventory.
5. Remedying all of the shortfalls by over the next 11 years (the 2035 deadline to stop the same of all ICE vehicles in California) will be insanely expensive and, given the lead time on major hardware, all but impossible.

Nuclear power is dead. It's too expensive to do it safely[*].

Unfortunately, it's pretty much required to be. Solar panels falling over and breaking just makes a mess on the ground. Windmills about the same (like some did in Iowa after a tornado destroyed them). Nuclear plants failing can potentially make an area uninhabitable for centuries, so the safety threshold needs to be higher.
Baseload is like gravity (Score:5, Insightful)
Denying the existence of baseload because you like intermittent sources is like denying the existence of gravity because you have your heart set on flying. But ignoring reality will end badly.
The population wants power when they need it and unreliable grids will remove Governments.
Business needs 24*7 power because industrial processes rely on equipment that is damaged by power outages.
Germany choices for power generation have wreaked havoc on its economy and it is now deindustrialising and in recession with 90% of its 2023 CO2 reductions coming from industrial cutbacks and closures.
Meanwhile France has 1/10 of the CO2 emissions of Germany because they use nuclear, their economy isn’t in recession and the have energy security and independence.
Heed the allegory of the three little pigs, wind and solar are the houses of straw and sticks and nuclear is the house of bricks. Yes nuclear is harder to build however it delivers power when you want it.

Nuclear power is really only good for baseload, it's not very good at load following. So the words "Or you have nuclear power" is a false dichotomy, unless you're willing to waste fuel to keep the grid up when demand accelerates faster than a nuclear power plant can ramp up.

Guess desert tortoises weren't that important (Score:2)
Having traveled I-10 from Palm Springs to Arizona for decades, the difference is very stark. Desert Center used to be a wide spot in the road with a few sad looking palm trees and some abandoned buildings. Now, there are solar farms literally as far as the eye can see. What happened to all those endangered species? The solar farms don't build around them. The land was scraped off down to bare mineral so nothing will grow there. Was all the talk about endangered species bullshit or does it no longer matter
Re: (Score:2)
The endangered species, which I'm sure you don't actually care about, are chilling in the shade from the solar panels. Its not like they're houses, built into the ground, forming a wall stopping the endangered species.
Fake news (Score:4, Insightful)
Renewables did not exceed 100% of energy demand on *any* of those 45 days. Rather, during some part of the day, about 1/3 of the day, renewables exceeded 100% of *power* demand.
Story as presented is wrong on two counts: (a) it was not total daily energy, but rather instantaneous power that was exceeded, and (b) it was only for part of the day, not whole day as the wording implies.
Also, while renewables may have exceeded total power demand during those periods, it does not follow that they actually *supplied* that demand, because the transmission and distribution system has constraints that might prevent that.
The real news is that California has a large installed renewable power base. That may come back to bite if non-renewables atrophy to the point where demand cannot be met when renewables are *not* meeting 100% or even 60% of power demand.
Nuance Patrol (Score:2)
This is great news, even with the caveats (mid-day, etc.). There's some interesting nuance though.
If you look at the ISO's supply page (https://www.caiso.com/TodaysOutlook/Pages/supply.html) you may note that nuclear trundles along on a flat line at about 1500 MW, and natural gas at 1500-1800 MW. Those are steam and combined-cycle plants that are difficult to ramp the output of quickly, and if shut off (such as in an emergency like a blackout) can take days to bring fully back on line. So they keep running.
