It costs less to run because less energy is used; I'm pretty sure incandescent bulbs aren't emitting anything by themself! "The push" is from the government, perhaps consumer demand is "the pull".

They do emit a lot of heat!
Almost all the energy consumed by appliances in your home gets ultimately converted into heat. For example, the picture on your TV is made from emitted light rays that are absorbed by various solid objects in your home and heats them up. Same for the sounds from your speakers. Your washing machine spins water and clothes around, which makes both the water+clothes and the body of the washing machine to heat up due to friction.
A counter example is a water pump, which converts electricity into gravitational potential energy of the water as it flows upwards.
which is not that bad if you want to warm your room a bit. The heat is not wasted, but added to the room. We use 250 watts to warm under the coffee tables. These are infrared-coated incandescent bulbs
