Iran possesses significant energy reserves, holding the position of the world's third-largest in proved oil reserves and the second-largest in natural gas reserves as of 2021. At the conclusion of the same year, Iran's share comprised 24% of the oil reserves in the Middle East and 12% of the worldwide total.[1]

In 2020, the Total Energy Supply (TES) in Iran was primarily sourced from oil and gas, with gas being the predominant contributor at 69% and oil at 29%. Nuclear power and renewable sources each accounted for 1% of the nation's TES.[2]

Iran also has the ability to generate significant power from renewable resources; due to the nation's closeness to the equator, 90% of its land area could provide solar power for at least 300 days a year.[3]

Oil in Iran is a major cause of air pollution[4] and greenhouse gas emissions.[5]

History

Iran is in a constant battle to use its energy resources more effectively in the face of subsidization and the need for technological advances in energy exploration and production. Energy wastage in Iran amounts to six or seven billion dollars (2008). The energy consumption in the country is extraordinarily higher than international standards. Iran paid $84 billion in subsidies for oil, gas and electricity in 2008.[6] Iran is one of the most energy-intensive countries of the world, with per capita energy consumption 15 times that of Japan and 10 times that of European Union. Also due to huge energy subsidies, Iran is one of the most energy inefficient countries of the world, with the energy intensity three times higher than global average and 2.5 times the middle eastern average.[7] Half of the country’s energy is wasted in domestic sector, 3.4 of which is wasted through single-occupancy vehicle use and 2/3 parts of power plants' energy are also wasted.[8]

Iran is one of the leading members of OPEC (Organization of Petroleum Exporting Countries) and the Organization of Gas Exporting Countries (GECF). Iran received $47 billion in oil export revenues, which accounts for about 50% of state revenues.[9] Natural gas and oil consumption both account for about half of Iran’s domestic energy consumption. With its heavy dependence on oil and gas revenues Iran continues to explore for new sources of natural gas and oil. Recently Iran has focused its energy sector on the exploration of the South Pars offshore natural gas fields in the Persian Gulf.[10]

Iran has become self-sufficient in designing, building and operating dams and power plants and it has won a good number of international bids in competition with foreign firms.[11][12]

Energy generation capacity of Iranian thermal power plants reached 173 terawatt hours in 2007, accounting for 17.9 percent of energy production in the Middle East and African region. Natural gas has been the main energy in Iran in 2007, comprising over 55 percent of energy needs, while oil and hydroelectricity accounted for 42 and 2 percent respectively. The region’s energy need will increase by 26.8 percent until 2012.[13] In 2017, the fuel consumption in Iran was equivalent to 5.5 million barrels of fuel per day (bpd), the rate of which is considered as the highest energy consumption rate in the world in terms of energy intensity.[14]

Energy plays an important role in Iranian politics. Robert Baer in his 2008 book The Devil We Know: Dealing with the New Iranian Superpower argued that Iran had attained the status of an energy superpower and was on its way to become a military-political superpower.[15]

Iran plans to create an energy saving company in conjunction with the Iranian subsidy reform plan (2014).[16] [citation needed]

Primary energy sources

Primary energy supply is around two thirds gas and one third oil, with tiny amounts from other sources.[18]

Natural gas

Iran's gas production, domestic consumption and exports[citation needed]

Iran is the world's third producer of natural gas (5.1% of the world's total and 184 BCM); which is primarily used for domestic electricity generation or heat production.[19] It contains an estimated 1,187.3 trillion cubic feet (33,620 km3) (Tcf) in proven natural gas reserves.[20] In 2005 a large share of Iran’s natural gas reserves were believed to remain untapped. About 62% of these reserves are located in non-associated fields. Iranian production of natural gas is expected to increase over the next few years due to continuing discoveries in the North Pars and South Pars regions.[21]

Domestic consumption has matched production at 3.6×10^12 cu ft (100 km3) in the year of 2005. Domestic consumption is expected to go up at about 7% per year for the following decade. The Iranian government has also subsidized natural gas prices along with gasoline prices, and this is expected to sustain this high level of domestic consumption. In lieu of this increasing domestic demand, natural gas exports are expected to decrease in the following years.[22]

In 2021, Iran ranked as the world's fourth-largest consumer of natural gas, behind the United States, Russia, and China. A significant share of its natural gas production is utilized domestically in various sectors. Over the last ten years, consumption of natural gas in Iran has risen by approximately 50%, influenced by a range of factors. These include heavily subsidized prices, an extensive distribution network, enhanced domestic production, and government initiatives aimed at replacing oil with natural gas in residential, commercial, and electric power sectors.[23]

Oil

Top oil-producing countries
(million barrels per day)

Iran has the second largest oil reserves in the world, and the third largest exporter of it.[citation needed] By the end of 2009, Iranian oil R/P ratio was 89.4 years which is the world's highest.[25] By 2009, Iran had 52 active rigs and 1,853 producing oil wells.[26]

Iran possesses abundant fuels from which to generate energy. Since 1913 Iran has been a major oil-exporting country. Oil industry output averaged 4 million barrels (640,000 m3) per day in 2005, compared with the peak output of 6 million barrels per day (950,000 m3/d) reached in 1974. Following the 1979 revolution, however, the government reduced daily oil production in accordance with an oil conservation policy. Further production declines occurred as result of damage to oil facilities during the war with Iraq. In the early 2000s, industry infrastructure was increasingly inefficient because of technological lags. Few exploratory wells were drilled in 2005. Iranian oil was nationalized in 1953 and thus is owned and operated by the National Iranian Oil Company (NIOC).

Iran held 10.3% of the world's total proven oil reserves and that figures out to be about 137.6 billion barrels (2.188×1010 m3) of oil reserves at the end of 2009.[25] Oil also is found in northern Iran and in the offshore waters of the Persian Gulf. Nevertheless, in 2005 Iran spent US$4 billion on gasoline imports, mainly because of contraband and inefficient domestic use that result from subsidies. Iran is one of the largest gasoline consumers in the world ranking second behind United States in consumption per car.[27]

There is a growing recognition that prices must rise faster to curb consumption and ease the burden on the public finances. Cheap energy has encouraged wasteful consumption in Iran, and a brisk business in smuggling petrol into Iraq, Turkey, Pakistan and Afghanistan. Demand has also been supported by rapid increases in car production in recent years.[citation needed] In the absence of imports, the car industry has developed strongly (albeit from a low base) with output reaching over 1m vehicles in fiscal year 2006/07 (March 21 – March 20).[28]

Iran oil production, domestic consumption and exports[citation needed]

The growth in consumption of domestically produced oil has been modest, owing to refining constraints. By contrast, fuel imports rose to 180,000 barrels per day (29,000 m3/d) in January 2005 from 30,000 barrels per day (4,800 m3/d) in 2000, and petrol consumption is estimated to have been around 1,800,000 barrels per day (290,000 m3/d) in 2007 (before rationing), of which about one-third is imported. These imports are proving expensive, costing the government about US$4bn in the first nine months of 2007/08, according to parliamentary sources.[28] Nearly 40% of refined oil consumed by Iran is imported from India.[29]

A USGS map of countries where oil is located.

Iran contains 27 onshore and 13 offshore oil-producing fields, largely concentrated in the southwestern Khuzestan region near the Iraqi border.[10] The Iranian government is heavily reliant on oil revenues and they have heavily subsidized the energy industries, which figures out to be about 12% of Iran’s GDP. However, domestic oil consumption has decreased due to the alternative use of natural gas. Economic growth from these resources is uncertain and stunted in Iran due to these subsidies and population growth. Iran has been unable to reach it full production levels due to a combination of sanctions and war plaguing the region. Iran’s oil fields have a natural decline rate at 8 percent for onshore wells and 10% for offshore fields. The Iranian recovery rate is currently approximately 27 percent, which is well below the world average. Iran needs structural improvements made to coincide with their enhanced oil recovery efforts.[10]

Oil:[24]

note: as of 2009, 1/3 of Iran's gasoline needs are imported because of insufficient domestic refining capacity, over-consumption and contraband.[31]

Nuclear energy

Iran plans to generate 23,000 MW of electricity through nuclear technology to meet its increasing demand for energy.[32] The first of four 915 MW reactors of Bushehr Nuclear Power Plant, built with help from Russia, came online in August 2010.[33] While nuclear power in the US costs a little over 10 cents per kilowatt hour, Iran, with domestic uranium enrichment capabilities, high interest rates, low energy output (a single 1,000-watt reactor), low efficiency, extremely slow reactor construction, and no reprocessing pays around 68 cents per kilowatt hour (this assumes a price of $140 per separative working unit and of $40 per kilogram of uranium).[34][obsolete source]

Hydro

Droughts have reduced hydropower.[35][36] The Energy Ministry plans to improve existing plants and build more small and medium hydro.[37]

Biofuel

In 2016, the Iranian Biofuel Society (IBS) in collaboration with the Vice Presidency for Science of Technology and Tehran and the Suburbs Bus Company executed the first urban pilot project for the consumption of waste cooking oil biodiesel in Tehran`s bus fleet in an attempt to generate public awareness regarding Global Climate Change, wherein they recommend “reducing net anthropogenic CO2 emissions to the atmosphere” and “minimizing anthropogenic disturbances of” atmospheric gasses by partial replacement of fossil fuels with waste-oriented biofuels.[38] The program was also supported by Small Grant Programme, Global Environmental Facility, United Nation Development Program (SGP/GEF/UNDP) Office in Iran.[39]

Solar

In 2021 there were 450 MW of solar power, less than 1% of installed capacity.[40][41] This is tiny compared to electricity demand and neighbouring countries.[42]

Iran has an average of 2,200 kilowatt-hour solar radiation per square meter annually, and 90% of the country has enough sun to generate solar power 300 days a year.[3]

Wind

In 2020 there were just over 300 MW of wind power, less than 1% of installed capacity.[43] The east is suitable to build more, and wind there matches annual demand variation, being higher in spring and summer.[44]

Geothermal

According to global tectonics Iran is impacted by subduction of the Arabian Plate under the Central Iranian Plate and four thrust faults: two that make the Southern Caspian Sea Mazandaran Depression and two in the north of Iran, part of the Caucasian Range. Mt. Sabalan and Mt. Sahand are two Quaternary Volcanos in the area. Sabalan is a large stratovolcano consisting of 3 summits named Soltan (4811), Heram (4612m) and Kasra (4573m). The stratovolcano is situated on a possible horst trending northeast-southwest and erupted at latest in the Holocene. Caldera collapsing has caused a depression about 400 m in height and 12 km in diameter. The lava flows consists of trachyandesite, andesite and dacite and pyroclastic deposits. There are 9 hot springs with a temperature in the range of 25-85 °C.[45]

Electricity

Iran electricity production by source[citation needed]
Energy consumption in Iran is 6.5 times that of global average.[46] It is estimated that 18.5% of electricity generated in Iran is wasted before it reaches consumers due to technical problems. Electric power wastage hit $1.1 billion in 2006.[47]
