As originally reported by The Thin Green Line, for every unit of fuel burned, only 13 percent of the potential energy is actually converted as useable output to power machines, and illuminate and heat buildings.
That means that 87% of the energy produced by fuel is wasted.
Who thinks it’s time to move to more efficient sources of energy?
Maybe the above 13% statistic statistic applies to the generation of electricity using fossil fuels? … If my natural gas furnace and/or water heater are condensing type, am I not converting more consumed energy to “usable output?”
