Welcome to the News community!
Rules:
1. Be civil
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. 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. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source. Clickbait titles may be removed.
Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.
7. No duplicate posts.
If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners or news aggregators.
All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

Yeah there's really no need for so many dams anymore, they were built to power hydroelectric stations that are no longer needed so this is a good thing.
Which is another really good point, sadly there's a lot of invasive plant species that were unknowingly brought over by Europeans mostly for ornamental purposes which have had a devastating effects on native plant life
How is hydro power no longer needed?
No clue why he would think that. Hydro power is the best source of carbon-free power. It's also the only reasonable way to do grid-scale storage we have. Unless we see a huge build-out in nuclear, hydro-power will be required for the next century.
I have no clue either as you misread what I wrote. MicroWave is correct, that was my meaning.
That's not true. There's TONS of viable alternatives. ex:
Pumped storage hydro is exactly what I was talking about when I said hydro is the only reasonable way to do grid-scale storage we have.
When your alternative is something that doesn't exist yet, you are reinforcing my point that hydro is the only viable grid-scale storage tech we have right now.
What's not well known is that dams also have a limited life -- they silt up. They produce most hydro power when new, which declines as silt fills the dam, raising the bottom/lowering head.
There's a great book I have somewhere, is it CADILLAC DESERT? about the big 20th century push to "tame nature" and dam every river to make it "produce". Total folly.
This is a insane take. We absolutely need hydro power right now. It was the leading source of electricity before coal. More dams, please.
You can do hydropower without dams. Dams are incredibly destructive to ecosystems.
Do educate me.
It just seems like a huge waste of energy / resources to remove an existing dam than to remediate it somehow. I didn’t see any mention of if this generated power or how it’d be offset.
Not really an environmental win if this hydro power capacity was replaced by coal.
