Nigeria's primary energy consumption was about 108 Mtoe in 2011. Most of the energy comes from traditional biomass and waste, which account for 83% of total primary consumption. The rest is from fossil fuels (16%) and hydropower (1%).
Nigeria has oil reserves of about 35 billion barrels (5.6×109 m3) and gas reserves of about 5 trillion cubic metres, ranking 10th and 9th in the world, respectively. Global production in 2009 reached 29 billion barrels (4.6×109 m3) of oil and 3 trillion cubic meters of natural gas. Nigeria is a member of the Organisation of the Petroleum Exporting Countries.

Ogoni people live historically in the Niger Delta. Ogoniland oil facilities are operated mainly by the Shell Petroleum Development Corporation (Nigeria) in the upstream and the Nigerian National Petroleum Company in the downstream since the 1950s. The Ogoni campaign against Shell Oil is led by the Movement for the Survival of the Ogoni People (MOSOP). MOSOP is campaigning for the expulsion of Shell from Ogoniland.
According to the UNEP assessment in 8/2011 the oil contamination is widespread in Ogoniland and oil spills continue still even in the old oil field areas. The Ogoni people live with this pollution every day. As Ogoniland has high rainfall, delay in cleaning of the oil spills leads to spread oil contamination in the farmlands. Oil contamination of land areas, sediments and swampland is extensive. The wetlands around Ogoniland are highly degraded and facing disintegration. Fishermen must move to less contaminated areas in search of fish. Current Ogoniland community have lived with chronic oil pollution throughout their lives. Of most immediate concern in 12/2011, community members at Nisisioken Ogale are drinking water contaminated with benzene, a known carcinogen, at levels over 900 times above the WHO guideline.
