Its not low cost if you need to emit tons of CO2 to maintain the network though. The issue with bitcoin when it comes to cost is that unlike traditional centralized systems, cheaper energy or more efficient computers don't translate to making it cheaper to run the network. What happens is that miners get to afford more hashes per second and the overall hashrate goes up, with the mining difficulty also going up to compensate, making mining even more wasteful.
