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! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
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.

Auto tldr bot missed this:

Currently, the country’s electricity grid is only permitted to have a maximum of 75 per cent renewables in its energy mix. That meant that some of the energy was exported to Britain and Ireland had to meet the rest of the demand using fossil fuels.

This limit has gone up over the years from 50 to 75 per cent since 2011 and is set to increase further to 95 per cent by 2030. It is in place because using entirely renewable power means changes have to be made to the country’s electricity grid.

[–] [email protected] 15 points 10 months ago (1 children)

I suppose at least if it was exported to the UK, it was hopefully still displacing some fossil fuel usage

[–] [email protected] 2 points 10 months ago* (last edited 10 months ago)

The UK sometimes has an excess of green energy as well.

I'm on a limited trial where I sometimes get completely free electricity for a couple of hours on specific days (my provider emails the day before to let me know and opt in).

I can charge my car, my solar batteries (they can charge from the grid if instructed), run the dishwasher, washing machine. And it costs nothing.

And then during the peak usage times, I'm using less power as I've done the stuff I would have done in those peak hours.

They don't do this from the goodness of their heart: there is an excess of energy available and they want it used instead of turning off production. Hopefully this rolls out to more areas soon.

I used to be on an "agile" tariff where the price changes every 30 minutes. Sometimes the price would go negative and I'd get paid to use energy. A good opportunity to turn on some fan heaters and warm the garden. Those flowers look a little chilly.

Why do they have to burn fossil fuels? That's fucking stupid

[–] dependencyInjection 37 points 10 months ago (2 children)

Im torn between giving an upvote for asking a question or giving a downvote for your following sentence given the answer was in the comment you were replying to.

Also, if you ask a question wouldn’t it be wise to wait for the answer before also passing judgement on something.

“Why is this like this? That’s fucking dumb.” Doesn’t quite work does it? How can it be dumb if you don’t know how it works. Why should we trust your assessment on its dumbness if you’ve already conceded you don’t know.

[–] [email protected] -3 points 10 months ago

They’re not asking how, they’re asking why. And something can absolutely appear as dumb without you knowing why something is one way or another.

It might not be dumb, but that doesn’t necessarily mean it doesn’t look dumb. Besides that’s entirely subjective.

Base load generators cant adjust their output quickly enough to match the daily demand curve. Your options are to keep them online at a fixed level 24/7, or cut them entirely. If you don't have enough renewable production to meet overnight demand, you have to meet that demand with base load generators, which means you have to keep those generators online. If you have to keep them online, and wind is providing more power than is being demanded, you have to cut the wind production to match demand.

To get those (usually coal-fired) generators offline, you need to drop your overnight consumption, add storage, switch to non-fossil baseload generators (nuclear), use less efficient "peaker" plants (usually gas turbine generators fired by natural gas or oil), or some combination thereof.

You're right, it is "fucking stupid", but it is due to the functional limitations of the equipment they currently have available. With those limitations, the best option is to export your excess wind production to someone who needs it, and improve your own grid to reduce reliance on fossil fuels.

[–] [email protected] 2 points 10 months ago

Makes more sense now 👌

[–] [email protected] 12 points 10 months ago (1 children)

Renewables suffer from intermittency .. production depends on whether the wind is blowing or the sun is shining .. and they can't be ramped up quickly to cope with increased demand. So you need a baseline source to take care of that and the only options we have are fossil fuel or nuclear.

[–] [email protected] 4 points 10 months ago

Ireland outlawed nuclear in 1999. Not a NATO member quite famously too

[–] [email protected] 10 points 10 months ago

It is in place because using entirely renewable power means changes have to be made to the country's electricity grid.

[–] [email protected] 3 points 10 months ago

This is the best summary I could come up with:

Wind power generation temporarily exceeded the total demand for electricity in Ireland for the first time ever this week.

Though Storm Agnes brought strong winds across the country, it isn’t unusual for it to reach this level.

What was unusual was the fact that it surpassed the demand on Ireland’s electricity grid throughout the entire island for the first time.

That meant that some of the energy was exported to Britain and Ireland had to meet the rest of the demand using fossil fuels.

In August, the amount of energy generated by wind increased by 71 per cent when compared to the same month last year.

The latest figures mean that in total, Irish wind farms provided 32 per cent of the country’s power over the first eight months of 2023.

The original article contains 438 words, the summary contains 131 words. Saved 70%. I'm a bot and I'm open source!

Just did a bike tour through Ireland and can confirm: is windy.

I don’t morally dislike wind turbines but wow that’s ugly.

[–] [email protected] 16 points 10 months ago (1 children)

You don't "morally" dislike wind turbines, but you went on the internet and took time to tell people that you believe they are "ugly".

I mean fuck it, right? Roughly 250,000 deaths a year at present, guaranteed to grow, but you don't like how it looks. How do you think coal powered power plants look? Oil refineries are also pretty easy on the eyes, yeah?

[–] [email protected] -3 points 10 months ago

You feel very strongly it seems. Aren’t we trying to protect this planet? None of those turbines are even trying to use the anti bird strike paint to protect the native species.

[–] [email protected] 5 points 10 months ago* (last edited 10 months ago) (1 children)

I've been impacted by anime wind turbine pictures and think it is kinda pretty and optimist-futuristic. E: but the huger ones are prettier.

[–] [email protected] -4 points 10 months ago

I wish I could feel this way.
