there are plenty low power proof of stake blockchains. they are becoming a lot more popular for scalability and efficiency reasons. currently everyone is on the hunt for the next proof of stake 'ethereum killer' with a lot of speculative investment. ethereum itself is planning a migration to proof of stake.

right now, i'm not personally a huge fan of proof of stake because of the 'nothing at stake' problem, but one will eventually take off.
