Energy Supplied
Many studies have documented how nuclear power plants generate 16% of global electricity, but provide only 6.3% of energy production and 2.6% of final energy consumption. This mismatch stems mainly from the poor consumption efficiency of electricity compared to other energy carriers, and the transmission losses associated with nuclear plants which are usually situated far away from sources of demand.
However The transmission losses associated with Nuclear plants, or indeed Hydroelectric plants, which are also usually situated far away from the sources of demand, are not high, as they use HVDC cables which have losses of just 3% over 1000 km. Similarly Nuclear power is not alone in appearing small when representing World energy consumption which includes non-electric fossil fuel heating and transport fuel, which Coal and Oil dominate. In 2008 world energy supply by power source was - oil 33.5%, coal 26.8%, gas 20.8% (fossil 81%), 'Other'(Geothermal power, peat, biofuels, solar, wind, etc.) 10.4%, nuclear 5.8% and Hydro 2.3%. Oil was the most popular energy fuel. Oil and coal combined represented over 60% of the world energy supply in 2008.

Famous quotes containing the words energy and/or supplied:
“I rather think the cinema will die. Look at the energy being exerted to revive it—yesterday it was color, today three dimensions. I don’t give it forty years more. Witness the decline of conversation. Only the Irish have remained incomparable conversationalists, maybe because technical progress has passed them by.”
—Orson Welles (1915–1984)
“When much intercourse with a friend has supplied us with a standard of excellence, and has increased our respect for the resources of God who thus sends a real person to outgo our ideal; when he has, moreover, become an object of thought, and, whilst his character retains all its unconscious effect, is converted in the mind into solid and sweet wisdom,—it is a sign to us that his office is closing, and he is commonly withdrawn from our sight in a short time.”
—Ralph Waldo Emerson (1803–1882)
