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

We are very close to solving this problem. The new scheme basically randomizes the block reward and equalizes the playing field.

Let's make cryptocurrency great again!
That will not work. Doge coin used to use the random block reward. But it failed as people do not mine the lower reward block.
