It's comparing apple and orange. Solar/wind aren't available on demand. How much would cost a wind power plant that has the same guaranteed power as a nuclear plant, including batteries for storage? what would be the environmental footprint of such a thing?


The whole purpose of electrical grids is to stabilize such things.

The word "guaranteed" is about lowest variance - most predictable. What is prone to unscheduled maintenance, breakdowns, forced outages, etc.

The forced outage rate of solar is almost 0, wind is about 1%. https://rmi.org/fuel-hand-make-coal-nuclear-power-plants-val...

In practice, forced nuclear outage is 1-2%. An additional 7% downtime is scheduled outages for refueling. Coal is about 15%.

Here's a live report: https://www.nrc.gov/reading-rm/doc-collections/event-status/... You can see about 7 are offline.

Disruptions are normal, daily, common occurrences and in practice, solar is pretty reliable in places like the Southern California desert where the grid-scale installations are built (example: https://www.google.com/maps/@34.7923792,-118.4060493,17707m/...). They are subject to occasional monsoons, but that's why there's more in other places such as down near the mexican border (https://www.google.com/maps/@32.7188416,-115.6454361,19457m/...). That's not farmland being replaced with solar panels btw. Instead it's called agrivoltaics (https://en.wikipedia.org/wiki/Agrivoltaics)

This is still early, scroll down to the map here: https://www.seia.org/research-resources/major-solar-projects... ... that's the kind of redundancy we're talking about.

Except it doesn't. Which is why Germany didn't decrease its gas plant capacity. They're needed when there's no wind.

The issue with wind/solar isn't forced outage. It's that the wind doesn't blow all the time, so comparing how much cost 1MWh of wind when the wind blows with 1MWh of coal is dishonest. You're comparing apple and oranges.


Right, forced outage of solar is 1%. Meanwhile, Germany is back to building coal plants because solar/wind doesn’t get you through the winter. Also, they postponed closing their nuclear plants. Jee, I wonder why?


You must read a lot of right wing media. That's a very nonlinear cherry picking of news items out of context and a packaging of them to puppet a talking point.

You can wonder why all you want but hobbling together headlines some of which are 3 years apart and pretending they're related is the thing you actually should be wondering about.


The facts I cited above directly contradict the myth of solar having a small forced outage. The fact of the matter is that solar is an intermittent source of energy. Sure, you can get away with saying that solar has a small forced outage, if you conveniently forget that solar generates a minuscule amount of power when the sun is out. You’ll have a hard time heating yourself with that, as the Germans discovered.

By the way, my source of information is mainstream French media.
