In 2021, the majority of energy in the United States comes from fossil fuels, with 36% of the nation’s energy coming from oil, 32% from natural gas, and 11% from coal.
United States Energy Consumption Per Capita
Nuclear provides 8%, and renewables, including hydroelectric dams, biomass, wind, geothermal and solar, provide 12%.
Oil: The Once & Future Fuel
As of 2006, national energy consumption in the country has grown faster than domestic energy production (the two were roughly equal) over the past 50 years. This difference was mainly covered by imports.
This does not include the large amount of energy used abroad to produce retail and industrial products consumed in the United States.
According to the Energy Information Administration, annual per capita energy consumption in the United States has remained fairly constant since the 1970s. The average between 1980 and 2010 was about 334 million British thermal units [BTU] (352 GJ) per capita. One explanation suggests that the energy needed to increase domestic consumption of manufactured equipment, vehicles and other goods is transferred to other countries. The production and transportation of these goods to the United States results in corresponding changes in greenhouse gases and pollution. On the other hand, the gains from increasing energy efficiency were at least partially consumed by the rebound effect. By comparison, between 1980 and 2008, the global average increased from 63.7 million BTU to 75 million BTU (67.2 to 79.1 GJ) per person per year. An energy consumption of 352 GJ per year means an average power of 11.16 kW due to the following power factors: 100% and considering the effect of peak load, the installed nameplate power per person should be higher. capacity corresponding to 67.2 GJ p.a. and 79.1 GJ p.a., 2131 and 2508 watts respectively. So all of humanity is not a 2000 watt society in 1980, but moving away from that level every year.
US primary energy consumption by source, 1776–2020. This graph corresponds to the EIA definition of “biofuel equivalent” for primary energy. It is the electricity produced by solar, wind, hydropower and geothermal energy multiplied by the average annual heat rate of fossil fuel power plants. This is the traditionally used definition of EIA.
Energy Is The Economy; Shrinkage In Energy Supply Leads To Conflict

From its founding until the late 19th century, the United States was an agricultural country with many forests. Energy consumption during this period was largely concentrated on fuels that were readily available. Rapid economic industrialization, urbanization, and the development of railroads led to greater use of coal, which by 1885 had overtaken wood as the nation’s primary energy source.
Coal dominated the following decades, but by the 1950s both oil and natural gas had taken over. The 1973 oil embargo caused an energy crisis in the United States.
In 2007, coal consumption reached a record high and was mainly used for electricity generation.
Why Canada Is One Of The World’s Largest Electricity Consumers
Natural gas has replaced coal as the preferred heating source for homes, businesses and industrial furnaces. Natural gas burns cleaner and is easier to transport.
Total energy consumption increased nearly 50-fold between 1850 and 2000, but per capita energy consumption increased only four-fold.
By 2009, per capita energy consumption in the United States had fallen to 7,075 tons of oil equivalent (296.2 GJ), down 12% from 2000, and in 2010 it had not reached its lowest level since the 1960s .
At the beginning of the 20th century, oil was a limited resource used to produce kerosene and lubricating oil and fuel for kerosene lamps. A hundred years later, it became the main source of energy for the United States and the rest of the world. This growth coincided with the automobile becoming a major force in American culture and economy.

Oil is also used as a source of plastics and other chemicals to power a variety of industrial processes, but two-thirds of US oil consumption today is used as transportation fuel.
The unique properties of petroleum as a transportation fuel in terms of energy stability, production costs, and refueling speed have favored its use over other fuels.

Each Country’s Share Of Co2 Emissions
Primary energy consumption in the United States in 2009 was 90,558 petajoules [PJ] (25,155 TWh), or about 294,480 megajoules [MJ] (81,800 kWh) per capita. In 2009, US primary energy consumption was lower than China’s at 3,960 PJ (1,100 TWh). Energy imports accounted for 26% of primary energy consumption. Energy imports are about 22% and annual CO2 lower
Wood energy is obtained by burning the durable cellulose material found in trees and woody shrubs.
Looking at renewable energy as a share of total primary energy consumption in 2011, wood consumption was 22%.
There are five main types/types of wood resources that can be converted into fuel energy, five of which are biomass, woody biomass, wood pellets, wood chips and cordwood.
Why China’s Climate Policy Matters To Us All
Biomass has been used since the days of cavemen and hunter-gatherer societies. Biomass is organic matter, meaning it is made up of elements derived from living organisms such as animals and plants. The most commonly used sources of biomass for energy production are plants, wood and waste. They are called biomass fuel sources. Biomass energy is a non-renewable energy source.
Woody biomass around trees and other woody plants is defined not only as a result of natural disasters, but also as a result of maintenance, regeneration and hazardous fuel reduction measures.
By the 1800s, the average American household was likely using wood as its primary source of energy consumption.
Wood consumption remains an important aspect of fuel consumption in various countries for many reasons, including cooking, heating and home lighting.
How Much Energy Does A House Use?
As mentioned, the second largest source of wood consumption was the United States. The wood was used in homes as wood burning appliances, stove wood and pellets in pellet stoves.
Between 1776 and 2012, the use of wood as an energy source remained stable, increased slightly between 1836 and 1926, and peaked in the late 1880s.
Oil is one of the largest sources of energy in the United States. The US influences the world’s oil reserves in both growth and development.
As the 20th century progressed, oil became important in providing heating and electricity for commercial and industrial sectors. Oil was also used for transportation. First for railways, later for cars.

As automobiles became more affordable, the demand for oil soared. Since the rise of the automobile industry, oil prices, demand and production have increased. Between 1900 and 1980, fuel had a direct relationship with gross national product (GNP). Moreover, oil crises often overlap with recessions, and governments have responded to them in different ways.
In the 1920s, oil prices were at an all-time high, and many regulators believed that oil was in short supply. Faced with calls to increase supply, Congress imposed massive depletion allowances on producers in 1926, greatly increasing returns on investment. This shift led to additional exploration activities and the subsequent discovery of large new oil reserves.
In the following decade, the situation changed and prices fell. It called for more “orderly” competition and set minimum oil prices. Instead of repealing the previous policy of the 1920s, Congress adopted a price support system. A similar cycle took place in the 1950s and 1970s.
Natural gas was the largest source of energy production in the US in 2016, accounting for 33% of all domestically produced energy.
The Carbon Footprint Of Household Energy Use In The United States
The US has overtaken Russia as the world’s largest producer of natural gas since 2009. US natural gas production reached record highs every year from 2011 to 2015. Marketed natural gas production was 28.8 trillion cubic feet (820 billion cubic meters) in 2015, up 5.4% and 18.9 trillion cubic feet (540 billion m3) more than in 2014.
Consumer prices for natural gas in the US are significantly lower than in Europe or Japan due to the large supply.
The low cost of natural gas, as well as its lower carbon footprint compared to coal, has fueled the rapid growth of electricity generated from natural gas.
Between 2005 and 2014, US production of liquefied natural gas (NGL) increased by 70% to 1.74 million barrels of oil equivalent (10.6 PJ).
