The household sector is responsible for about 15 to 25 per cent of primary energy use in OECD countries and for a higher share in many developing countries. Average per
capita household energy use in developed countries is about nine times higher than in developing countries

Transportation sector use of energy experienced tremendous growth overall, but registered noticeable pauses in 1974, 1979-1982, 1990 and 1991, and 2001. In 2004, petroleum accounted for 97 percent of the sector’s energy, and motor gasoline accounted for two-thirds of all petroleum used in the sector.
