I love some of the answers how a heat pump works....pulls the cold out of the house to leave only heat. Having worked in the electric utility business for 40 years I would talk to high school students regarding energy use and I would always throw in some off the wall information to keep interested. Do you know why fluorescent tubes turn black on the ends before they burn out.....a fluorescent tube sucks the darkness out of the room and once the tube is full of darkness it quits working. :@
