Title: Energy in Africa
Content:  North Africa is dominant in oil and in gas, for Libya obtains approximately 50% of the oil reserves available in Africa. Libya designated US$5 billion to assert programs and regulations that will reduce carbon emissions. Resources, such as oil and gas, are also prevalent in Algeria, in addition to natural gas. According to the Renewable Energy Sector in N. Africa, solar capacity is also extremely relevant in North Africa. The total power installed in North Africa region was roughly 61.6 GW in 2012. This is mostly made up of hydro accounting for nearly 10%.
Title: Economy of Africa
Content:  Africa has significant resources for generating energy in several forms (hydroelectric, reserves of petroleum and gas, coal production, uranium production, renewable energy such as solar, wind and geothermal). The lack of development and infrastructure means that little of this potential is actually in use today. The largest consumers of electric power in Africa are South Africa, Libya, Namibia, Egypt, Tunisia, and Zimbabwe, which each consume between 1000 and 5000 KWh/m2 per person, in contrast with African states such as Ethiopia, Eritrea, and Tanzania, where electricity consumption per person is negligible. Petroleum and petroleum products are the main export of 14 African countries. Petroleum and petroleum products accounted for a 46.6% share of Africa's total exports in 2010; the second largest export of Africa as a whole is natural gas, in its gaseous state and as liquified natural gas, accounting for a 6.3% share of Africa's exports. Only South Africa is using nuclear power commercially.
Title: Natural resources of Africa
Content:  Africa has a large quantity of natural resources, including diamonds, sugar, salt, gold, iron, cobalt, uranium, copper, bauxite, silver, petroleum, and cocoa beans, but also tropical timber and tropical fruit...... Recently discovered oil reserves have increased the importance of the commodity on African economies. Sudan and Nigeria are two of the main oil producers. The United States and European countries took most of the Democratic Republic of the Congo's (DRC) oil production. Oil is provided by both continental and offshore productions. Sudan's oil exports in 2010 are estimated by the United States Department of State at US$9 billion. Five countries dominate Africa's upstream oil production. Together they account for 85% of the continent's oil production and are, in order, from highest to lowest output: Nigeria, Libya, Algeria, Egypt and Angola. Other African oil producing countries are Gabon, the DRC, Cameroon, Tunisia, Equatorial Guinea, the Republic of the Congo, Ivory Coast, and more recently, Ghana. Exploration is taking place in a number of other countries that aim to increase their output or become first-time producers. Included in this list are Chad, Sudan, Namibia, South Africa, and Madagascar, whilst Mozambique and Tanzania are potential oil producers.
Title: Mineral industry of Africa
Content:  of Africa's liquefied natural gas (LNG) exports. The United States received 11% of Africa's LNG exports, and countries of the Asia and the Pacific region, 1%. In 2005, Europe received 35% of Africa's petroleum exports; the United States, 32%; China, 10%; Japan, 2%; and other countries in the Asia and the Pacific region, 12%. West African countries sent 45% of their exports to the United States and 32% to China, Japan, and other countries in the Asia and the Pacific region. North African countries sent 64% of their exports to Europe and 18% to the United States. Intraregional exports to African countries amounted to only 
Title: Petroleum industry in the Republic of the Congo
Content:  Congo holds the fifth-largest proved reserves of natural gas in the Sub-Saharan Africa, at 3.2 Tcf, A majority of natural gas around 65% is reinjected and 21% flared.
Title: Ghana
Content:  believed to have up to 5 Goilbbl to 7 Goilbbl of petroleum in reserves, which is the fifth largest in Africa and the 21st to 25th largest proven reserves in the world. It also has up to 6 e12cuft of natural gas in reserves, which is the sixth largest in Africa and the 49th largest natural gas proven reserves in the world. Oil and gas exploration off Ghana's eastern coast on the Gulf of Guinea is ongoing, and the amount of both crude oil and natural gas continues to increase. The Government of Ghana has drawn up plans to nationalise Ghana's entire petroleum and natural gas reserves to increase government revenue.
Title: Energy in Africa
Content:  African Energy Policy Research Network and co-worker Waeni Kithyoma, Africa is third largest in crude oil reserves (behind the Middle East and Latin America), third largest in natural gas resources (behind the Middle East and Europe), second greatest for uranium (behind Australia), and is plentiful in hydro energy potentials and other renewable energy, such as bio-energy and solar energy. Professor Iwayemi states that there are conventional energy sources in Africa: hydroelectric and wood fuels, coal lignite, crude oil, natural gas and nuclear fuels, and there are unconventional energy sources, such as solar, geothermal, biomass, oil and tar sands, wind energy and tidal energy from the influence of the sea. In addition, South Africa alone obtains the sixth largest coal reserves on the planet, after China, the US, India, Russia and Australia. Specific renewable resources in South Africa include solar, wind, hydropower, wave energy, and bio-energy.
Title: Sub-Saharan Africa
Content:  by the West, China, India, and other emerging economies, even though it holds only 10% of proven oil reserves, less than the Middle East. This race has been referred to as the second Scramble for Africa. All reasons for this global scramble come from the reserves' economic benefits. Transportation cost is low and no pipelines have to be laid as in Central Asia. Almost all reserves are offshore, so political turmoil within the host country will not directly interfere with operations. Sub-Saharan oil is viscous, with a very low sulfur content. This quickens the refining process and effectively reduces costs. New sources of oil are being located in sub-Saharan Africa more frequently than anywhere else. Of all new sources of oil, ⅓ are in sub-Saharan Africa.
Title: Tropical desert
Content:  Natural gas and oil are complex hydrocarbons that formed millions of years ago from the decomposition of animals and plants. They are the world's primary energy source and exist in viscous, solid, liquid or gaseous forms. The five largest oil fields are in Saudi Arabia, Iraq and Kuwait. The largest petroleum-producing region in the world is the Arabian Desert.
Title: Mineral industry of Africa
Content:  more than 50% of the export earnings of Mali (gold), Mauritania (iron ore), Mozambique (aluminum), Namibia (diamond, uranium, gold, and zinc), and Zambia (copper and cobalt). Gold was a significant source of export earnings in Ghana, South Africa, and Tanzania. Diamond was a significant source of export earnings in the Central African Republic and South Africa, as was uranium in Niger. Africa's natural gas exporters included Algeria, which had 72% of the continent's natural gas exports, Nigeria, 13%, Egypt, 9%, and Libya, 6%. Europe received 91% of African total natural gas exports and was the destination of 95% of Africa's natural gas exports by pipeline and
