Bitcoin helps to solve a massive problem (centralization) so I wouldn't say it's not worth it. That said, there are many PoS and DPoS cryptocurrencies to choose from which use almost no electricity and would actually help to decentralize the economy much better than Bitcoin could on its own. ...We can't achieve decentralization by pooling all of the world's money on a single asset. That makes no sense.
