Edit: People's general understanding of the scale of economies is genuinely terrifying to witness.
What's the deprecation schedule? Which financial "context" is it calculated within? A household may benefit from governmental support and profitable, while the aggregate financial situation may or may not be so. What timeline is it calculated on? A 5-10 year window may be unprofitable, while a larger one may be. An even longer one may change numbers completely...
That's evening peaker gas plants in most places. After batteries push gas out of that market they go on to morning peaks and so on.
So far it's covered about 70% of my usage and 5.7 Mwh. I don't have a full year of data yet so I expect that number to grow as it includes the summer months. I drive an EV and this includes the car.
This is the problem still in the US. Even at ~$0.23/kwh delivered in the northeast, you're looking at an ROI of nearly five years. Fine if you can float that kind of cash to feel better about yourself, but the economics just aren't there for most people, especially in cheaper parts of the country where rates are ~$0.12. Even financing you're looking at a monthly payment equal to or greater than an electric bill. Of course if you have the time to amortize it you'll come out ahead, but there's simply no cheap solution that can actually save real money out of pocket in any reasonable amount of time beyond theoretical future savings on paper. It will never be a true solution without massive subsidisation that reduces out of pocket to a 1-2 year horizon.
Spain opted out of this system and is now enjoying cheap wholesale electricity, which is fueling an industrial revival.
To the discussion of whether $50B/y is a big figure or not. EU has around 400GW of PV installed. Cost to install per 1kW ranged between $600 and up to $4000 because a big chunk of that capacity was built when prices were much higher. If we consider average price at $1000 this means $400B on capex alone + yearly operational expenses. It can still be profitable (assuming current PV prices can be sustained + installed capacity doesn't grow faster than storage) but it's going to be many years until the investment is recouped and it starts to actually "save money for Europeans".
In any case, of course it's still nice to depend less on imported oil, even if not for money savings.
New advances in nuclear is what I hope for. First experimental SMRs are being installed in several places of the world, others are in design stage. Looks like a hopeful technology.
People don't give a fuck until gasoline is 2€ per liter.
But these things don't get momentum in a vacuum. People need to advocate for them beforehand, so that when the time is right, the decision makers will know who to turn to.
There are more immediate ways for China to influence Europe.
Meanwhile the recent oil debacle showed how fragile a system it is to have fossil fuels shipped across the planet.
Also, the more panels we already have, the less reliant we are. Energy doesn't stop flowing because deliveries of new panels stop during a conflict. You just pause expansion. A very different scenario to fuel reserves running dry in weeks.
That's 15% yearly
As an adult, one of the things that fascinate me is self-sufficiency: the idea that you can buy a solar power system, install it, and use your own power -- without getting a bill in the mail every month, many times feeling like a victim of modern day suburban subjugation.
I'm still a good little obedient peasant, but I hope one day I can rely more on well water/rain catchment system, solar power, and propane.
Getting 70% of your electrical usage from your own solar power system has to be a good feeling.

Electricity is pre approved to increase a minimum of 5% a year (it just went up 16% this year for people out of town), so the savings will only increase.
I’ll pocket something like $35k in 25 years for $0. Best investment ever.
I’m in canada in a tight valley where it snows a boatload.

Pretty sure it's all tax funded.
Where I am as soon as the government introduced subsidies every single installer jacked their price 2-5x, now they all start right at the threshold at which the subsidies kicks in, amazing... it costs twice as much to the community but "0" to the individual

Nuclear energy wouldn't even be a thing without heavy govt subsidies. And it keeps needing subsidies. No nuclear plant is economical without subsidies. (The operators admit this themselves.) In contrast, the solar and wind industry is eventually carrying itself without subsidies. In many parts of the world that's already the case since tech and market have matured.

That's too simple of a statement. Sure, govt grants are involved in subsidies for installation and the loan interest. But that thing is then generating electricity, which is what saves them the money.
So it's not "all" tax funded. Some of it is the sun's energy, and that was the whole point.

I live in a heavily subsidized state and quotes ranged from (after subsidies/incentives) 5-6 year ROI to 20-25 year ROI.

Yes. I’m very happy my taxes are spent on things that improve the lives of everyday people rather than endless wars.
Either spend it on productive things, or have zero taxes.
