Energy Supply Vs. End Use
Total world energy supply is distinct from actual world energy usage due to energy loss. For example, in 2008, total world energy supply was 143,851 TWh, while end use was 98,022 TWh. Energy loss depends on the energy source itself, as well as the technology used. For example, Nuclear Power (as of 2008) loses 67% of its energy to water cooling systems.
In 2008, world nuclear energy was 8,283 TWh (constituting 5.8% of total world energy), while nuclear energy end-use was 2,731 TWh (2.8%).
Given significant energy supply-to-usage ratios, It is important to note these differences across various energy sources.

Famous quotes containing the words energy and/or supply:
“After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
“Local television shows do not, in general, supply make-up artists. The exception to this is Los Angeles, an unusually generous city in this regard, since they also provide this service for radio appearances.”
—Fran Lebowitz (b. 1950)
