Africa, with its wealth of natural resources and fast-growing population, may have a significant impact on international energy markets over the next 25 years. The International Energy Outlook 2018 (IEO2018) analyzed uncertainty associated with future energy demand growth in Africa by examining a sensitivity case in which a faster rate of economic growth in Africa—compared with the IEO2018 Reference case—results in greater energy consumption and a larger manufacturing sector through 2040.
The IEO2018 Reference case projects that real African gross domestic product (GDP) will grow at an average rate of 3.8% per year from 2015 to 2040, and the IEO2018 Africa High Growth case projects an average growth rate of 5.0% per year over the same period. In these cases, Africa’s energy consumption is projected to grow from 23 quadrillion British thermal units (Btu) in 2015 to 35 quadrillion Btu in the IEO2018 Reference case and to 44 quadrillion Btu in the Africa High Growth case. Energy consumed in the industrial sector (manufacturing, construction, mining, and agriculture) accounts for most of the difference between cases.
Within the industrial sector, non energy-intensive manufacturing—pharmaceuticals and electrical equipment, for example—sees the largest increase in energy consumption. Energy consumption for non energy-intensive manufacturing in 2040 is 7.9 quadrillion Btu in the IEO2018 Reference case and 10.9 quadrillion Btu in the Africa High Growth case. The energy-intensive manufacturing sector’s energy consumption increases by 1.0 quadrillion Btu, and non manufacturing energy consumption increases by 0.5 quadrillion Btu.
A higher rate of GDP growth in the Africa High Growth case leads to African manufacturing growing as a share of the economy and the services share shrinking relative to the IEO2018 Reference case. The manufacturing sector accounts for 19% of total output in the IEO2018 Reference case in 2040, with services accounting for 47%. In the IEO2018 Africa High Growth case, however, the manufacturing share of Africa’s economy in 2040 rises to 24%, and the services share drops to 37%.
Even though GDP and energy consumption both grow in Africa in the IEO2018 Reference case, energy consumption per capita declines between 2015 and 2040. Africa’s population growth rate is higher than its energy consumption growth rate, underscoring the difficulties the continent will have in meeting its energy needs. In the Africa High Growth case, however, energy consumption rises from 19 million Btu per person to 22 million Btu per person between 2015 and 2040, compared with a decline to 17 million Btu per person in the IEO2018 Reference case over that period.
Although energy consumption per capita in 2040 in the Africa High Growth case is 25% higher than it is in the IEO2018 Reference case,the African value is still lower than in many countries. African energy consumption per capita in 2040 is projected to be one-half of the level in India, one-fourth of the level in Brazil, and one-tenth of the level in Russia in the IEO2018 Africa High Growth case.
The net effect of the Africa High Growth case on the rest of the world, because of trade and global supply chains, shows limited impacts on other countries—either positive or negative—in terms of output. The biggest effect is on non energy-intensive manufacturing in Eurasian countries, where output is 3% lower in the Africa High Growth case. This slight drop occurs because Africa’s availability of low cost labor gives it a competitive advantage in manufacturing.

In 2019, consumption of renewable energy in the United States grew for the fourth year in a row, reaching a record 11.5 quadrillion British thermal units (Btu), or 11% of total U.S. energy consumption. The U.S. Energy Information Administration’s (EIA) new U.S. renewable energy consumption by source and sector chart published in the Monthly Energy Review shows how much renewable energy by source is consumed in each sector.
In its Monthly Energy Review, EIA converts sources of energy to common units of heat, called British thermal units (Btu), to compare different types of energy that are more commonly measured in units that are not directly comparable, such as gallons of biofuels compared with kilowatthours of wind energy. EIA uses a fossil fuel equivalence to calculate primary energy consumption of noncombustible renewables such as wind, hydro, solar, and geothermal.

Wind energy in the United States is almost exclusively used by wind-powered turbines to generate electricity in the electric power sector, and it accounted for about 24% of U.S. renewable energy consumption in 2019. Wind surpassed hydroelectricity to become the most-consumed source of renewable energy on an annual basis in 2019.
Wood and waste energy, including wood, wood pellets, and biomass waste from landfills, accounted for about 24% of U.S. renewable energy use in 2019. Industrial, commercial, and electric power facilities use wood and waste as fuel to generate electricity, to produce heat, and to manufacture goods. About 2% of U.S. households used wood as their primary source of heat in 2019.
Hydroelectric power is almost exclusively used by water-powered turbines to generate electricity in the electric power sector and accounted for about 22% of U.S. renewable energy consumption in 2019. U.S. hydropower consumption has remained relatively consistent since the 1960s, but it fluctuates with seasonal rainfall and drought conditions.
Biofuels, including fuel ethanol, biodiesel, and other renewable fuels, accounted for about 20% of U.S. renewable energy consumption in 2019. Biofuels usually are blended with petroleum-based motor gasoline and diesel and are consumed as liquid fuels in automobiles. Industrial consumption of biofuels accounts for about 36% of U.S. biofuel energy consumption.
Solar energy, consumed to generate electricity or directly as heat, accounted for about 9% of U.S. renewable energy consumption in 2019 and had the largest percentage growth among renewable sources in 2019. Solar photovoltaic (PV) cells, including rooftop panels, and solar thermal power plants use sunlight to generate electricity. Some residential and commercial buildings heat with solar heating systems.

Based on the U.S. Energy Information Administration's (EIA) annual survey of electric generators, natural gas-fired generators accounted for 43% of operating U.S. electricity generating capacity in 2019. These natural gas-fired generators provided 39% of electricity generation in 2019, more than any other source. Most of the natural gas-fired capacity added in recent decades uses combined-cycle technology, which surpassed coal-fired generators in 2018 to become the technology with the most electricity generating capacity in the United States.
Technological improvements have led to improved efficiency of natural gas generators since the mid-1980s, when combined-cycle plants began replacing older, less efficient steam turbines. For steam turbines, boilers combust fuel to generate steam that drives a turbine to generate electricity. Combustion turbines use a fuel-air mixture to spin a gas turbine. Combined-cycle units, as their name implies, combine these technologies: a fuel-air mixture spins gas turbines to generate electricity, and the excess heat from the gas turbine is used to generate steam for a steam turbine that generates additional electricity.
Combined-cycle generators generally operate for extended periods; combustion turbines and steam turbines are typically only used at times of peak load. Relatively few steam turbines have been installed since the late 1970s, and many steam turbines have been retired in recent years.

Not only are combined-cycle systems more efficient than steam or combustion turbines alone, the combined-cycle systems installed more recently are more efficient than the combined-cycle units installed more than a decade ago. These changes in efficiency have reduced the amount of natural gas needed to produce the same amount of electricity. Combined-cycle generators consume 80% of the natural gas used to generate electric power but provide 85% of total natural gas-fired electricity.

Every U.S. state, except Vermont and Hawaii, has at least one utility-scale natural gas electric power plant. Texas, Florida, and California—the three states with the most electricity consumption in 2019—each have more than 35 gigawatts of natural gas-fired capacity. In many states, the majority of this capacity is combined-cycle technology, but 44% of New York’s natural gas capacity is steam turbines and 67% of Illinois’s natural gas capacity is combustion turbines.
Countries that are not members of the Organization for Economic Cooperation and Development (OECD) in Asia, including China and India, and in Africa are home to more than two-thirds of the world population. These regions accounted for 44% of primary energy consumed by the electric sector in 2019, and the U.S. Energy Information Administration (EIA) projected they will reach 56% by 2050 in the Reference case in the International Energy Outlook 2019 (IEO2019). Changes in these economies significantly affect global energy markets.
Today, EIA is releasing its International Energy Outlook 2020 (IEO2020), which analyzes generating technology, fuel price, and infrastructure uncertainty in the electricity markets of Africa, Asia, and India. A related webcast presentation will begin this morning at 9:00 a.m. Eastern Time from the Center for Strategic and International Studies.

IEO2020 focuses on the electricity sector, which consumes a growing share of the world’s primary energy. The makeup of the electricity sector is changing rapidly. The use of cost-efficient wind and solar technologies is increasing, and, in many regions of the world, use of lower-cost liquefied natural gas is also increasing. In IEO2019, EIA projected renewables to rise from about 20% of total energy consumed for electricity generation in 2010 to the largest single energy source by 2050.
The following are some key findings of IEO2020:
IEO2020 builds on the Reference case presented in IEO2019. The models, economic assumptions, and input oil prices from the IEO2019 Reference case largely remained unchanged, but EIA adjusted specific elements or assumptions to explore areas of uncertainty such as the rapid growth of renewable energy.
Because IEO2020 is based on the IEO2019 modeling platform and because it focuses on long-term electricity market dynamics, it does not include the impacts of COVID-19 and related mitigation efforts. The Annual Energy Outlook 2021 (AEO2021) and IEO2021 will both feature analyses of the impact of COVID-19 mitigation efforts on energy markets.
