I think miners should start invest on renewable energy source (solar panels, wind turbines) to lessen the impact of bitcoin on environment?
I agree with you that investors on miners should invest on renewable energy but their power consumption not even a fraction of the industrial and manufacturing company.
There are already miners shift to renewable practice to save money. Renewable energy may expensive to start but it is more cheaper in the long run.
miners have strong incentives for various industries to consume less energy. the miners should be able to find ways to reduce the damage because cryptococcal mining requires a lot of electricity to make mining more effective.
