Has anyone done any serious studies on electricity consumption due to cryptocurrency related activities like mining? Possibly with comparison between different currencies and feasibility of maintaining such consumption? Is there an argument to be made for or against them in the context of global warming?
Electricity consumption has nothing to do with the global warming.Electricity production creates the global warming.If we produce electricity with green techonologies ,the consumption of such energy won`t be a problem.
Anyway,after 21M bitcoins the mining will stop and this issue will disappear.
Nope, mining won't stop because mining is needed to push blocks for the confirmation of transaction. After the last halving one century from now, the block reward will be zero and the only reward for miners will be the transaction fee that was speculated to be enough because of the global adoption and relative price of Bitcoin that time.
