Someone mark this words...

I would bet in the future the humans will have miners farm with their own electricity generators. Some farms powered by rivers and dams, and some others will have nuclear plants for enormous farms. And isn't a crazy idea at all, I mean the energy bill of a mining farm is really high.

And about the article... mining is done by miners and if someone gets a cloud mining service that means the miner is running somewhere in the world, and it's consuming energy any way...
