Just about every appliance has the energy consumption given somewhere on

The actual footprint of course depends on use - and a low wattage kettle
won't save energy to boil the same amount of water - probably the reverse.

Surely there are other factors beside power consumption? Appliances have
to be manufactured, transported, and disposed of at end of life, and these
involve CO2 production too.
