Remember that electricity is only a carrier of energy and is produced somewhere else! Most often, the same fossil fuels mentioned above, are also used to generate electricity, a process which also results in environmental pollution; this time in a central location rather than distributed in individual homes.
Siinkohal tuleb meeles pidada, et elekter on üksnes energiakandja, kusjuures elektrienergiat toodetakse mujal. Enamikel juhtudel kasutatakse fossiilkütuseid ka elektrienergia tootmiseks. Selline protsess tekitab küll keskkonnareostust, kuid sellisel juhul ei saasta keskkonda iga majapidamine, vaid üksikud suured elektritootjad.
