The electricity for 1BTC trade could power a house for a month

Those who missed the boat and now hope everyone else's fun will be spoiled fail to notice through their already shaky logic that this problem is being solved. Proof of stake means we don't have to waste nearly as much electricity for a functioning cryptocurrency. There are already coins using PoS successfully (Lisk, Peercoin). Ethereum plans to move to proof of stake. Can we stop beating this dead horse?

I'm sure it seems like that if you don't understand that the energy consumed has almost no correlation to the number of transactions being put through.
