For example, induction burners are more efficient for cooking than traditional electrical burners in the same way that microwaves are—targeting the energy to a particular material (metal for induction, water molecules for microwaves) means that less energy is wasted in warming up the kitchen. We can replace furnaces with heat pumps or with thermal

Heating and air conditioning account for half of residential consumption, which is why the single best thing we could do for the energy budget is to keep the heat
