Why do games have to use so much electricity? They should be fine with a few kb of storage and maybe some minimal networking. Back in the day games were completely fine and playable in tiny cartridges. Games should be regulated to not consume a certain amount of network and processing power.
On the other hand, without the PoW mechanism of Bitcoin, it's impossible to have the properties that bitcoin has - global decentralised money and payment network. If you believe otherwise, make one! Very quickly no one will be willing to pay for Bitcoin, and all those "wasted electricity" will suddenly become available again.
