I'm shocked and disheartened by how infrequently environmental concerns are brought up when discussing crypto. Proof of Work vs Proof of Stake, security, storage size - these are problems for the network and those that want to see it become a real part of our economy. (I am one of those) But the amount of energy being used to mine bitcoin is a real problem - it's not just a technical challenge (like the problems abov…
Actually, cryptocurrency mining serves an environmentally-friendly function in energy markets because it absorbs excess capacity in the geographic regions where mining is done (i.e. where electricity is cheap) and allows it to be “exported” rather than go to waste. Interesting stuff.
If cryptocurrency mining goes to countries with subsidized energy and they become part of maxing out that country's energy output, the country may be forced to create new energy sources to provide to the population (aka, higher environmental impact + cost). This push may be partially blamed by the cryptocurrency servers.
In other words, not all cryptocurrency mining servers as utilizing just the extra capacity casually created by a city/state.
