Ask Lemmy
A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, and toxicity are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !askusa@discuss.online
Reminder: The terms of service apply here too.

Not necessarily.
Solar has a problem where, if you install enough capacity to meet demand during short, overcast winter days, you have twice the capacity you need in spring or autumn, and 4 times as much capacity as you need during long, clear summer days.
That excess production tanks the value of the power produced. Itnis already regularly driving power prices negative, making it impossible to recoup the value of your installation. Since it's cheaper for you to just buy electricity on the market than to install solar, you don't install solar. Nobody does. Solar installation never expands enough to meet winter demand.
Unless we can monetize that cheap summer power. If we have some way of profitably consuming that excess power, we have every reason to maximize solar rollout.
Crypto can do that just as well as anything else.
The issue is monetizing the excess power produced by adequately-sized solar facilities for 9 months out of the year. Getting enough people to point giant lasers into space would solve the overcapacity problem that comes with solar generation outside of the tropics. Crypto has a slightly higher ROI.
Desalination, fischer-tropsch synfuel production, hydrogen electrolysis, demand-shaping of conventional industries like steel production and aluminum smelting, widespread adoption of electrified parking garages are some other options. Even other maligned, power-hungry technologies like AI can address the overproduction problems of solar better than conventional grid-scale storage solutions.
You having a bad day? What can I do to make your life better?
I'm not trying to solve any problems with Crypto. I'm trying to use their purchasing of electricity to solve a different problem: seasonal variation in solar production.
Due to long, clear, summer days, and short, cloudy winter days, if you have enough solar panels to meet your demand in winter, you have about 400% of what you need to meet demand in the summer, even after accounting for air conditioning loads.
That excess power on the grid crashes the price of power. Unless you can find someone else to buy it, or some way tonuse it. To have enough solar generation capacity to meet your needs year round, you need something that can suck up excess power in the summer. If you can't monetize that excess, you'll never be able to get enough solar online to meet demand year-round.
Storage can conceivably address daily fluctuations, but it won't solve seasonal variation.
