A lot of the "waste energy" can be used to heat space,  greenhouses, homes, in what's commercially known as "cogeneration."  Supposedly when you use your car heater in winter you're using cogeneration.  Cogeneration is widely used in Finland for building and apartment heating (even under some Helsinki street intersections to melt ice in winter).  check wikipedia and google.
