Some standart argues for POW hardliners I like to say something in the beginning:
1) We can use green power for mining
Green power is an illusion. Even windmills or dams pollute the enviroment
NO!
There is no CO2 pollution from wind, hydro ,geothermal ,solar, tidal and even nuclear reactors. Do you research before posting such BS.
The only way to reduce BTC's CO2 pollution is by using green energy sources
If you are referring to CO2 " cost" to manufacture the equipment , it is very small compared to energy these sources are giving , thus there is no point of pointing out.
