Why has the world started to mine coal again? (lemmy.ml)

With climate change looming, it seems so completely backwards to go back to using it again.

Is it coal miners pushing to keep their jobs? Fear of nuclear power? Is purely politically motivated, or are there genuinely people who believe coal is clean?

Edit, I will admit I was ignorant to the usage of coal nowadays.

Now I'm more depressed than when I posted this

With some high voltage long-range transmission lines you could viably do it pretty much everywhere. Just requires some cooperation.

Yes it will slightly reduce efficiency over very long distances, but it's not unreasonable amounts.

Long range transmission of AC power is limited to about 40 miles. DC can be transmitted much farther, but the infrastructure is substantially more expensive (because it’s more dangerous), so that’s only done for extreme need.

We aren’t getting away from having many power generators all over the place, so one location-dependent storage solution isn’t going to solve all the problems.

I might also add there's smart algorithms being developed for about 5y+ now that distribute power surplus and deficiency over a grid. This will probably be key. Just take a look at "energy metering".
