I agree, however I am hopeful. Majority of the 'proof-of-work' mining for Bitcoin comes from renewable energy. But it does create unnecessary wastage.
There are other other eco-friendly blockchains that use a 'proof-of-stake' model, where excessive mining is NOT required. Ethereum, the second largest in market cap ('value') is currently migrating to this model. And there are many other new blockchains coming out such as Solana and Avalanche which is efficient (enough), with proof-of-stake and other hybrid technology from day one.
