No they don't.
Gaming is the sole demand for all consoles and GPUs produced in the world. Those devices alone consume a lot more energy than Bitcoin miners (by about an order of magnitude).
Gold and Silver are extremely expensive to mine energy-wise.
The banking system is amazingly expensive to run. Not only it requires lots of buildings and transportation for millions of workers, it also requires a lot of computing resources to be run -- without even guaranteeing you can withdraw your money from banks, and with your money there being corroded due to inflation.
Bitcoin, in comparison, is actually pretty "green" once you consider the value it provides: a distributed ledger with 10+ years of operation and no flaws/attacks detected, meaning it's the safest store of value known to mankind, while not being under any control of any organization or government.
In any case, even if your point that Bitcoin is "evil" as it requires "too much energy to run" is true, what are you going to do about it? Feel free to short Bitcoin in a futures market, and leave all your wealth allocated in assets associated to fiat currencies.
