Power used in global terawatt (TW), between 1965 and 2005 .
Power used in global levels of increasing detail
Energy intensity of different economies The graph shows the amount of energy that is needed to produce a dollar of GNP for selected countries. The GNP is referred to purchasing power parity in 2004, and 2000 dollars adjusted for inflation .
Energy consumption per capita versus GDP per capita The graph represents the energy per capita versus green energy income per capita of all countries with more than 20 million people, representing over 90 of the world’s population. The image shows the broad relationship between wealth and energy utility company consumption .
GDP and energy consumption in Japan from 1958 to 2000. The data show a strong correlation between GDP and energy use, but also shows that this link may be broken. After the oil crisis of 1973 and 1979 the use of enegia stagnated while Japan’s GDP continued to grow after 1985, under the influence of low oil prices, energy use returns to its historical relationship with GDP .
World energy supply in TW
Oil Decline of the other remaining 57 ZJ of oil on the planet. The annual consumption of oil in2005 electricity was 0.18 ZJ. There is significant uncertainty regarding this information. if you are looking for the best electricity and gas deals, then you must consider in New York 11 ZJ of future additions of extractable reserves could be optimistic.

Available renewable energy. The volume of environment the cubes represent the amount of geothermal energy, wind deregulation and solar available in TW, while only a small part is recoverable. The small red cube shows the overall energy consumption in proportion .
Solar energy as it spreads over the planet and radiated back into space. The values listed in PW running water 1015 watts .
In this article we buying green employ the units, prefixes, and the magnitudes of the International System Power in Watts or Watts (W) leading suppliers of electricity and natural gas and energy in Joules (J), to directly compare the sun and organic matter consumption and energy resources worldwide. One watt is one joule per second.
Total world energy consumption in 2005 was 500 EJ ( 5 x 1020 J) (or 138,900 TWh) to 86.5 from burning fossil fuels, although there are at least 10 of uncertainty in these data. This equates to an average power of 15 TW ( 1.5 x 1013 W). Not all the world’s economies track their energy consumption with the same rigor, and the exact energy content of a barrel of oil or ton of coal varies widely in quality. The bulk of global energy resources from solar irradiation of utilities the Earth – wind some of this energy is stored in the form of fossil energy, another part of it is usable in direct or indirect such as via wind power, hydraulic or of the waves. part of the , is one of the leading energy suppliers in NY State The term solar constant is the amount of solar radiation incident per unit New York State area, measured on the outer surface of the Earth’s atmosphere, in a plane perpendicular to the rays. The solar constant includes all types of solar radiation, not just visible light. Satellite measurements of the situation around 1366 watts per square meter, while a 6.9 fluctuation throughout the year – from 1412 W / m at the beginning of sustainable energy resources January until the 1321 W / m in early July, given the variation the distance from the Sun, a few thousand parts per day. For the Earth, complete with a cross section of 127,400,000 KMA , the power obtained is 1740 -1017 watts, about 3.5 gas .
The estimates of remaining worldwide energy resources vary, with an ESCOs estimated resource of about 0.4 fossil YJ (1 YJ 1024J) and available nuclear fuels such environment as uranium exceeding 2.5 YJ. The range of fossil fuels is growing up 0,6-3 YJ if estimates of reserves of methane hydrates are accurate and if they get their extraction is technically possible. Mainly due to the Sun, the world has access to a usable energy that exceeds 120 PW (8,000 times the total used in 2004), or 3.8 YJ / yr, dwarfing all non-renewable resources.
