Does the wind blow year round? I’m imagining a similar case for wind, then you can say that for the union of these two sets, renewables are cheaper than legacy energy
Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear

I you live where sun is abundant all year round… In which case (Las Vegas?) I would question the choice of having humans living in a fucking desert in the first place. But man I wish I could cover my needs between October and March here in Europe but no battery will help me store so much for so long :-/

I would have loved that but having a wind turbine is… not easy. Permits, psychotic attitude from neighbours… but that have been my go-to given we don’t have a stream to go hydro. I’m still happy with covering 8 ou of 12 months with our setup but it’s still unnerving to swallow the costs of the setup + utilities for winter months…

Wind kinda has to go big for efficiency. It’s hard to beat the laws of physics on this. Not really feasible for individuals to do in a meaningful way unless you have a whole farm.
Solar panels are workable-ish. Residential rooftop is OK, but the real cost benefit is from filling big, flat fields with racks. Homes have to be a boutique setup every time, and labor cost adds up.
If you want to be (semi-) independent of traditional power utilities, the way to go is co-ops. You and all your neighbors go in on buying a field and putting solar/wind/storage on it

Residential wind for electricity generation is not really recommendable afaik, but it could be viable for some amount of heat generation, potentially: …lowtechmagazine.com/…/heat-your-house-with-a-mec…

“bad” solar areas are actually amazing for 9 months, and if you heating needs are met by other means, then winter can keep the lights on and still do cooking. The path to meeting winter heating needs is hot water and “heated dirt/sand” storage with hydronic floor heating (where more water is delivered at 30C is easier to manage than radiators at 80C) that can be stored during ample fall solar with no heat or cooling load.

Exactly that. My worst case winter month (not even by day and I like to be warm every day) is generating less than 25% of consumption. Not that other winter months are much better.

I feel you… I got a nice 3k€ to pay for electricity just for winter months and that’s with a quite performant heat pump. But at least zero emissions here…

I’ve got solar with net metering. But apparently I leave in a much gentler environment still, compared to you. Got a small house (<150sqm), winters reach -20°C and have sustained -10°C for multiple weeks and yet the bill hasn’t reached past 1400€/mo before solar panels. Everything in the house is runs on electricity.

With 2 electric cars… Belgium here so it’s not the tundra either but the house is sizeable and doesn’t share walls. Hot water alone was 150/200 kWh a month. It all adds…

theres also nothing much going on LV too, limited schools and and private physicians.

Yeah I saw that… Though I’m 3 years into solar and my measurements aren’t so positive. I am definitely not covering 62% of our needs yearly. The 4 less sunny months are killers when you need heating.
AA5B@lemmy.world 3 weeks ago
I saw a video where a guy was claiming vertical solar panels can effectively generate more power more often. They can catch a little something when the sun is low in winter , or on the shoulder hours of sun-up/down, where traditional solar can’t, and they don’t get snow buildup

it’s a trade-off. the average generation curve depends on the inclination; each has its pros and cons

Panels are also cheaper than most fencing, and easy to DIY install.

I wanted to make a joke about plug flow electricity because your in the UK I believe from what you said, but I don’t know enough about it. Doesn’t sound like it could supplement much energy in its current stages. I am curious to see if it ever makes any substantial amount in the next 10 years.
If you haven’t heard of it, it is a process of maximizing the use of air pockets created in catching falling water (rain) and allowing it to split in a way that can convert the kinetic energy of it essentially to about 10% electrical energy. Supposedily about 5x as effective as just letting the water fall on its own and turning it to mechanical energy. There’s something about it that seems whimsical about it to me. Not sure why.

Using rain for electricity sounds like too fun to be efficient enough xD I’m gonna look into that :)
HubertManne@piefed.social 3 weeks ago
62 percent could be 7 months all the time and 5 never right? So if those 4 months only get you 20% but the others give you ninety something. When I see that 62 I see it as over half the year it will work out good.
a4ng3l@lemmy.world 3 weeks ago
Yeah but that would not account for the electricity need: in winter we need between 1000/1300 kWh mainly for heating / domestic hot water. Other months under 250 even if we use air conditioning. So if you cover the 7 nice months you still get absolutely wrecked by the dreaded 4 in the winter cost wise…
