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:
“Crime is naught but misdirected energy. So long as every institution of today, economic, political, social, and moral, conspires to misdirect human energy into wrong channels; so long as most people are out of place doing the things they hate to do, living a life they loathe to live, crime will be inevitable.”
—Emma Goldman (1869–1940)
“One cool judgment is worth a thousand hasty counsels. The thing to do is to supply light and not heat.”
—Woodrow Wilson (1856–1924)
