| World energy use per sector | ||||
|---|---|---|---|---|
| 2000 | 2008 | 2000 | 2008 | |
| TWh | %* | |||
| Industry | 21,733 | 27,273 | 26.5 | 27.8 |
| Transport | 22,563 | 26,742 | 27.5 | 27.3 |
| Residential and service | 30,555 | 35,319 | 37.3 | 36.0 |
| Non-energy use | 7,119 | 8,688 | 8.7 | 8.9 |
| Total* | 81,970 | 98,022 | 100 | 100 |
Industrial users (agriculture, mining, manufacturing, and construction) consume about 37% of the total 15 TWh. Personal and commercial transportation consumes 20%; residential heating, lighting, and appliances use 11%; and commercial uses (lighting, heating and cooling of commercial buildings, and provision of water and sewer services) amount to 5% of the total.
The other 27% of the world's energy is lost in energy transmission and generation. In 2005, global electricity consumption averaged 2 TWh. The energy rate used to generate 2 TWh of electricity is approximately 5 TWh, as the efficiency of a typical existing power plant is around 38%. The new generation of gas-fired plants reaches a substantially higher efficiency of 55%. Coal is the most common fuel for the world's electricity plants.
Total world energy use per sector was in 2008 industry 28%, transport 27% and residential and service 36%. Division was about the same in the year 2000.
