That is why I made the analogy to a space heater - because mining would be a free side benefit of something you actively use to keep warm.
The environmental impact is also negligible if the power you're using is coming from solar or wind.
- Klinky 6y agoAn idle computer clocks down and sips power. Going full bore mining coins results in significant power usage increases. We're talking 10 watts vs 100s of watts.
- trixie_ 6y agoSmall space heaters run at 750 watts on the low setting.
- qes 6y agoA single Bitcoin miner runs at 1500w on its only setting and sounds like a small aircraft preparing for takeoff.
- beervirus 6y agoThat matters if you live in Texas. It doesn't matter if you live above the Arctic Circle.
- thebean11 6y agoRight but if your goal is to heat your apartment (and your alternative heat source is also electric) running the computer is a pretty efficient heat source.
- contravariant 6y agoWell, efficient is hardly the right phrase. When it comes to heating using electricity then 100% efficiency is on the low side. A heat pump could be many times more efficient.
- lalaland1125 6y agoI just also want to add that gas heating is also effectively >100% efficient relative to electricity because there are no losses incurred on the power generation side.
- a1369209993 6y agoThat depends on how you're making that gas. IIRC algae (the primary ingredient in most fossile fuels) are less than 10% efficient at converting sunlight into chemical energy after metabolic expenditures. (There's also the part where the sun is <<0.00001% efficent at turning fusion energy into sunlight-that-hits-earth, but that problem isn't specific to gas heating.)
- londons_explore 6y agoIt is sad that "heat" and "efficiency" are defined like this... "100% efficiency" should be the Carnot's theorem efficiency limit...

- perl4ever 6y agoWhat people say is that all electric heat is equally efficient in the sense that all the delivered watts ultimately become heat, but at least in the general area where I live, electric heat of any kind is not efficient in the sense that it is significantly more expensive than burning fuel (natural gas, oil, etc.) at home.
