How *do* you make a toaster more efficient?
You use a radiant element which has a particularly favourable range of
wavelengths for browning.
You use a radiant element which only emits where there is bread.
You hang your toast-to-be on a washing line or rack and allow most of
its moisture content to evaporate before trying to toast it.
You use sophisticated controls so that you never suffer the double-cost
of burning the toast and then having to toast another batch. (Including
disposing of the burnt toast, using more toast-to-be, cleaning the
toaster and surrounding area, redecorating the kitchen, etc.)
But none of that reverses the simple physical fact that
cooking/heating/baking/toasting will all use less energy by using a high
power for a short time than using lower power for a longer period due to
heat loss - nop matter how good the insulation.
I agree. Doesn't mean there aren't things that could be done if the aim
is simply lower electricity consumption.
