And unlike incandescents, which generate a lot of waste heat, LEDs don't get especially hot and use a much higher percentage of electricity for directly generating light.

That is not much but, given that the average vehicle loses roughly 70 % of the energy supplied to it by its fuel to waste heat and friction, recovering even a small percentage of this with thermoelectric technology would be worthwhile.»

As the third story in our series will discuss, there are certainly times when wood energy can be beneficial — but those scenarios tend to play out at much more local scales, in which true waste wood is used for heat and power.

For example, Organic Rankine Cycles (ORC) which operate at much higher - pressure levels, are both larger in size and less efficient at the low temperature where the largest bulk of waste heat is found.

It is more efficient in the winter to draw heat from the relatively warm ground than from the atmosphere where the air temperature is much colder, and in summer transfer waste heat to the relatively cool ground than to hotter air.
