Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect!
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

We have to start looking at personal renewables more? Each home could have their own small windmill or solar panel. Let's point in that direction.
Those potentially have the same issue. The solution to filling the gaps in production from renewable sources is not necessarily more panels or more windmills, it's having energy storage somewhere to keep surplus energy when it's being produced (e.g. during the day, or when the wind is blowing) available to be used when it's not.
So in your example, each home could also have its own battery bank. Or, a larger battery bank could be placed somewhere on the electricity grid.
It could be a wall of small wind wheels for the home and yes a stored battery location on-site. A friend of mine took us to see their friend who had their own small(ish) wind turbine and it only had to have 10 large batteries. That was years ago.
If your appliances are efficient and your usage is moderate, you don't need much to generate enough power to run your home. And, provided you don't also need to charge an EV in the garage...
The 8 Bit Guy just did a video detailing his setup, which is all solar panel driven, and he rode out a day in the recent Texas heat running his air conditioners and so forth just on his solar panels and stored backup power. He has a comparatively rinky-dink number of panels, just a few over his little side porch and a couple more hung on his fence.
I imagine someone with one side of their roof paneled plus or minus a small windmill could easily power their own home as well as provide a surplus to charge a battery bank.
Just to add to this, we had 14 panels installed with a powerwall on an East/slightly NE, West/slightly SW roof at 55°Northern latitude. In the 7 weeks since we had them installed, every day we've made more than enough power for our usage. On more than 60% of the days so far we've filled the battery too and had to put up to 7kwh into my car. The worst days we've still made enough to power our house for more than 24 hours. This is genuinely way more than I ever expected to make and if we get a fraction of that through winter we'll not need to charge the battery from off peak electricity as much as I had planned.
Now, granted this far north we'll cycle from one extreme to the other but it seems like such a simple win to have panels for when you can and storage to smooth out usage on everything we can. You can get a surprising amount of power from just a "bright" day, even with cloud cover.
55 degrees North? Damn, we're in Seattle and we're at 47.6 so that's some seriously lacking sun compared to the rest of the US. That's incredible news.
I was and still am blown away. I'm already thinking how I can fit more on to our house and for other efficiencoes we can make, next one is likely to be a heatpump.
Our system has 5.6kwh theoretical capacity but were split 10 panels to the rear and 4 to the front. Even still, we've manage to peak at 3.64kwh output. For context we've had our system just short of 8 weeks and made 821kwh as of this post.

That's exactly what I'm talking about, I really hope it catches on.
This is a misrepresentation of what he said, which was a discussion on net metering and high feed in tarriffs.
The people with surplus can pay for the grid infrastructure with energy they produce consumed elsewhere at whatever its value is. When they have no surplus they can pay with money.
What makes you think personal renewable are going to be more efficient than large scale renewables? The sun doesn't magically shine in the middle of the night on personal homes, the wind doesn't magically blow only in residential areas...
