The amount of electricity consumed by some appliances these days is astonishingly low.
The LED lightbulb in my room for example uses 9 Watts. If I left it on maximum brightness constantly for a whole year this would come to:
9 Watts * 24 hours per day * 365 days / 1000 = ~79kWh.
That would cost me 79kWh * 14.714p/kWh = £12 in electricity for the year.
If supplied 100% by especially dirty coal this might produce 71kg of CO2.
This is a small amount which could be offset on the EU carbon trading market for about £1.80.
While also not worth fussing much too about, at least heating systems and air conditioners do use a meaningful amount of energy! Get your house insulated and then don’t sweat about the rest.
