The mines and the tracks absolutely do.
Setting up energy generation to power it on site, rather than drag more energy transport that cuts through more of the local ecosystem, doesn’t.
- defrost 3y ago> Setting up energy generation to power it on site .. doesn’t Rethink that carefully - how many acres for an open pit mine? Now, how many acres for solar panels, etc. to generate power to dig that mine? If someone objects to landuse for the mine, then solar power is going to at least double the amount of land used. I'm remaining neutral here on the ethics - but don't kid yourself that there's magically no additional land clearing from onsite solar.
- bertil 3y agoTo extract a thousand tons, estimates are around 6,700 kWh [0]. That’s a bit less than what one of the larger windmills can produce in an hour (7.5 MW). The largest mine I know produces 25.6 million tonnes of ore per year, so (/365/24) three times that. I’m sure we can find room for three windmills over the 16.53 km^2 of that mine.
