Today I Learned

What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

Besides we can still use that same land for crops with agrivoltaics

Now do lithium mine externalities.

Again, our proposal isn’t that we should cover all of this land in solar panels, or that it could easily power the world on its own. We don’t account for the fact that we’d need energy storage and other options to make sure that power is available where and when it’s needed (not just when the sun is shining). We’re just trying to get a sense of perspective for how much electricity could be produced by using that land in more efficient ways.

Now do iron and aluminum mine externalities for ICE cars, which carry hundreds of pounds extra of those metals, plus much rarer cataysts like platinum and rubidium. The business community keeps quoting one white paper written by Volvo on this, but of course, no one actually read that paper because the authors saw fit to exclude the metals used in engines and transmissions in ICE cars when comparing to EVs. There is so much bullshit math on both sides of this argument, no one is realizing how we are getting distracted from major sources of pollution that continue unfettered like shipping, air travel and cement production.

ICE engines are mostly cast aluminum, which can be recycled trivially and indefinitely with renewable energy and no environmental harm.

Lithium batteries cannot be recycled without environmental harm.

Biofuels (due to inefficiency) are net negative emitters.
