Has anyone bumped in to any concrete numbers over the environment impact of our usage of suboptimal software, eg js+web tech instead of native desktop apps, the power usage of crypto currencies, the cost of constantly brute forcing problems instead of elegant solutions?

Any data is much appreciated - it trying to write something intelligent about this.

@e8johan this site puts the marginal energy cost of a single transaction at a bit over 500 kWh. For context, a 310L fridge consumes approximately 280 kWh/year.

@rfox @e8johan it's worth noting that mining is only one component of many in a functioning cryptocurrency (and some currencies don't use it), but it accounts for very close to 100% of the energy consumption

@waterbear @e8johan sure - but in a proof of work cryptocurrency, don't you always require mining for transaction verification?

@rfox @e8johan yes. There are non-proof of work currencies which would have much lower energy consumption even if they were as popular as Bitcoin
