Re: Bitcoin already using too much power by 2020?

I just stumbled upon this article that claims Bitcoin could be consuming as much energy as Denmark by 2020 Shocked

Since I gave up mining in 2014, I've almost forgotten just how much electricity goes into making Bitcoins. This got me wondering whether the devs are already working on a solution to this problem. Anyone knows what the plan is?

for in my opinion would be nice BTC in 2020, but no one knows what happens in the future. super advance of the question
