alt Hacker NewsGlobal population approximately: 8.44E+09, Energy to heat 1 liter of water in electric kettle: 80 watt hours, 1 Watt hour ~ 2.78E-15 exajoules. Global energy consumption approximately: 600 exajoules.
8.44E+980 watt hours(2.78E-15 exajoules/watthours)= 1.88E-03 exajoules 1.88E-03/600 = 3.12E-6 or .000312% of the global energy use.
In simple words. Banning kettles would do nothing to cut global energy use.
Isn't that only the energy of 1 liter per person per year? I think most people heat more water than that.
(Also I think bitcoin energy usage is also on the order of 0.001% of global energy use.)
