Energy in the United States

From Wikipedia, the free encyclopedia

U.S. primary energy consumption [1]
U.S. renewable energy consumption by source [2]

Most of the energy used in the United States in 2021 came from fossil fuels, as 36% of the nation's energy originated from petroleum, 32% from natural gas, and 11% from coal. Nuclear power supplied 8% and renewable energy supplied 12%, which includes biomass, wind, hydro, solar and geothermal. [1]

The United States was the second-largest energy consumer in 2021 after China.[3] The country had a per-capita energy consumption of 295 million BTU (311 GJ), ranking it tenth in the world behind Canada, Norway, and several Arabic nations.[4] Imports peaked in 2005, when they represented 30% of total consumption. A consistent decline occured for the next 15 years. In 2019, net imports were negative for the first time since 1952. As of 2021, the US net exports 5.7% of energy production.[5]

According to the Energy Information Administration, the annual per-capita energy consumption in the U.S. varied between 300 to 360 million BTU (320 to 380 GJ) for half a century starting in the late 60's. In 2020, per capita consumption dipped below 300 million BTUs for the first time since 1967.[6] In comparison, the world average increased from 68.3 to 77.5 million BTU (72.1 to 81.8 GJ) per person between 1980 and 2019.[7]

The United States' portion of the Electrical grid in North America had a nameplate generation capacity of 1,213.05 GW and produced 3,987.83 TWh in 2021.[8] [9] Natural gas overtook coal as the dominant source for electric generation in 2016. While coal use has been dropping, it remained larger than either nuclear or renewables.[10]

History[edit]

Energy amounts: the EIA "fossil fuel equivalence" definition of primary energy multiplies the electricity produced by solar, wind, hydro and geothermal using the average heat rate of fossil-fuel fired plants for that year.[11]
Percentages: over centuries, energy consumption has evolved from burning wood to fossil fuels (coal, oil, natural gas), and in recent decades to using nuclear, hydroelectric and other renewable energy sources.[12]
Per-capita energy use in the United States

From its founding until the late 19th century, the United States was a largely agrarian country with abundant forests. During this period, energy consumption overwhelmingly focused on readily available firewood. Rapid industrialization of the economy, urbanization, and the growth of railroads led to increased use of coal, and by 1885 it had eclipsed wood as the nation's major energy source.[13]

Coal remained dominant for the next seven decades, but by 1950, it was surpassed in turn by both petroleum and natural gas. The 1973 oil embargo precipitated an energy crisis in the United States.[14] In 2007, coal consumption was the highest it has ever been, with it mostly being used to generate electricity.[15] Natural gas has replaced coal as the preferred source of heating in homes, businesses, and industrial furnaces, which burns cleaner and is easier to transport.[16]

Although total energy use increased by approximately a factor of 50 between 1850 and 2000, energy use per capita increased only by a factor of four.[citation needed] As of 2009, United States per-capita energy use had declined to 7.075 tonnes of oil equivalent (296.2 GJ), 12% less than 2000, and in 2010, to levels not seen since the 1960s.[17] At the beginning of the 20th century, petroleum was a minor resource used to manufacture lubricants and fuel for kerosene and oil lamps. One hundred years later it had become the preeminent energy source for the United States and the rest of the world. This rise closely paralleled the emergence of the automobile as a major force in American culture and the economy.

While petroleum is also used as a source for plastics and other chemicals, and powers various industrial processes, today two-thirds of oil consumption in the U.S. is in the form of its derived transportation fuels.[18] Oil's unique qualities for transportation fuels in terms of energy content, cost of production, and speed of refueling all contributed to it being used over other fuels.[citation needed]

From the beginning of the United States until 1973, total energy (including electrical) use increased by about 3% per year, while population increased an average of 2.2% per year. Per-capita energy use from 1730 to 1870 was about 100 million BTU (110 GJ) per person. In the 20th century this increased to around 300 million BTU or 320 GJ (332 million BTU or 350 GJ per person per year in 1981).[19]

Primary energy production[edit]

U.S. energy flow, 2019. A quad is 1015 BTU, or 1.055 × 1018 joules (1.055 EJ). Note the breakdown of useful and waste energy in each sector (dark vs. light gray) due to the nature of heat engines, which cannot convert all thermal energy into useful work and consequently lose a portion of their heat to the environment.

Primary energy use in the United States was 90,558 petajoules [PJ] (25,155 TWh) or about 294,480 megajoules [MJ] (81,800 kWh) per person in 2009. Primary energy use was 3,960 PJ (1,100 TWh) less in the United States than in China in 2009. The share of energy import was 26% of the primary energy use. The energy import declined about 22% and the annual CO2 emissions about 10% in 2009 compared to 2004.[24] In 2020, the U.S as a whole produced 87.79 exajoules of energy.[25]

Fossil Fuels[edit]

Coal[edit]

Generation of electricity is the largest user of coal, although its use is in decline. About 50% of electric power was produced by coal in 2005, declining to 30% in 2016 and 23% in 2019.[26][27] Electric utilities buy more than 90% of the coal consumed in the United States.[28]

The United States is a net exporter of coal. Coal exports, for which Europe is the largest customer, peaked in 2012 and have declined since. In 2015, the U.S. exported 7.0% of mined coal.[29]

Coal has been used to generate electricity in the United States since an Edison plant was built in New York City in 1882.[30] The first AC power station was opened by General Electric in Ehrenfeld, Pennsylvania in 1902, servicing the Webster Coal and Coke Company.[30] By the mid-20th century, coal had become the leading fuel for generating electricity in the U.S. The long, steady rise of coal-fired generation of electricity shifted to a decline after 2007. The decline has been linked to the increased availability of natural gas, decreased consumption,[31] renewable electricity, and more stringent environmental regulations. The Environmental Protection Agency has advanced restrictions on coal plants to counteract mercury pollution, smog, and global warming.

Natural Gas[edit]

US natural gas production, imports, and exports
Natural gas production by field

Natural gas was the largest source of energy production in the United States in 2016, representing 33% of all energy produced in the country.[32] Natural gas has been the largest source of electrical generation in the United States since July 2015.

The United States has been the world's largest producer of natural gas since 2009, when it surpassed Russia. U.S. natural gas production achieved new record highs for each year from 2011 through 2015. Marketed natural gas production in 2015 was 28.8 trillion cubic feet (820 billion cubic metres), a 5.4% increase over 2014, and a 52% increase over the production of 18.9 trillion cu ft (540 billion m3) per day in 2005.[33]

Because of the greater supply, consumer prices for natural gas are significantly lower in the United States than in Europe and Japan.[34] The low price of natural gas, together with its smaller carbon footprint compared to coal, has encouraged a rapid growth in electricity generated from natural gas.

Between 2005 and 2014, U.S. production of natural gas liquids (NGLs) increased 70%, from 1.74 million barrels of oil equivalent (10.6 PJ) per day in 2005 to 2.96 million barrels of oil equivalent (18.1 PJ) per day in 2014. The U.S. has been the world's leading producer of natural gas liquids since 2010, when U.S. NGL production passed that of Saudi Arabia.

Although the United States leads the world in natural gas production, it is only fifth in proved reserves of natural gas, behind Russia, Iran, Qatar, and Turkmenistan.

Petroleum[edit]

Oil is one of the largest sources of energy in the United States. The United States influences world oil reserves for both growth and development.[35] As the 20th century progressed, petroleum gained increasing importance by providing heating and electricity to the commercial and industrial sectors. Oil was also used in transportation; first for railroads and later for motor vehicles.[36]

US oil production, imports, & exports

As automobiles became more affordable, demand for oil quickly rose. Since the rise of the automobile industry, oil price, demand, and production have all increased as well. Between 1900 and 1980, fuel was directly correlated with Gross National Product (GNP). Furthermore, oil shocks have often coincided with recessions, and the government has responded to oil shocks in several ways.[37] In the 1920s, oil prices were peaking and many commentators believed that oil supplies were running out. Congress was confronted by requests to augment supplies, so a generous depletion allowance was enacted for producers in 1926, which increased investment returns substantially. This change induced additional exploration activity, and subsequently the discovery of large new oil reservoirs.[38]

In the next decade the situation was reversed with prices low and dropping. This resulted in demands for more "orderly" competition and set minimum oil prices. Rather than repealing the previous policies enacted in the 1920s, Congress enacted a price-support system. Similar cycles have occurred in the 1950s and 1970s.[38]

Nuclear[edit]

Renewables[edit]

U.S. renewable energy sources [39]

Renewable energy in the United States accounted for 13.2% of the domestically produced electricity in 2014,[40] and 11.2% of total energy generation.[41] As of 2014, more than 143,000 people work in the solar industry and 43 states deploy net metering, where energy utilities buy back excess energy generated by solar arrays.[42]

Renewable energy reached a major milestone in the first quarter of 2011, when it contributed 11.7% of total U.S. energy production (2.245 quadrillion BTU or 2.369 EJ of energy), surpassing nuclear energy production (2.125 quadrillion BTU or 2.242 EJ).[43] 2011 was the first year since 1997 that renewables exceeded nuclear in total U.S. energy production.[44]

The development of renewable energy and efficient energy use marks "a new era of energy exploration" in the United States, according to President Barack Obama.[45] Studies suggest that if there is enough political will, it is feasible to supply the whole United States with 100% renewable energy by 2050.[46][47]

Biomass[edit]

Wood energy is created by the incineration of rigid cellulose material found in trees and woody bushes captures Among the most significant renewable energy sources is wood energy.[48] When examining the Renewable Energy as a Share of Total Primary Energy Consumption in 2011, wood consumption is 22%[49] There are five main types/forms of wood resources that can be converted into fuel energy, the five are biomass, woody biomass, wood pellets, wood chips, and cordwood.[50]

Biomass has been used since cavemen and hunter and gatherer societies. Biomass is organic, indicating it is constructed up of elements obtained from living organisms such as animals and plants. The most prevalent biomass sources used for energy are plants, wood, and waste. Biomass fuel sources are how they're referred to. Biomass energy is a nonrenewable energy source.[51]

Woody biomass, which encompasses trees and other woody plants, is defined as a result of maintenance, regenerating, and hazardous fuel reduction initiatives, as well as natural disasters.[11]

The average American family until the 1800s was most likely to use wood as the main source of energy consumption. Wood would be considered the predominant renewable energy source used until the mid to late 1800s.[15] The consumption of wood continues to be a significant aspect of fuel in various different countries, for numerous reasons including cooking and heating, as well as lighting their houses.[16] As mentioned, the second largest source of wood consumption was in the United States. Wood was used within homes as wood-burning appliances, wood in fireplaces, as well as pellets in pellet stoves.[17] Ranging from 1776 up until 2012, the use of wood as an energy source has been steady, there has been a minuscule increase from 1836 to 1926, with a peak in the late 1880s.[18]

Geothermal[edit]

The Geysers in Northern California is the largest complex of geothermal energy production in the world.

Hydro[edit]

Hydroelectricity was considered one of the largest sources of electricity until 2019.[52] Hydroelectricity was responsible for about 6.3% of the U.S. utility-scale electricity generation, as well as about 31.5% of total utility-scale renewable electricity generation in 2021.[52] Hydroelectric energy, also known as Hydroelectric Power or hydroelectricity, is a type of energy that generates electricity by utilizing the potential energy of water, such as water running over a waterfall. For centuries, individuals have exploited this energy.[53]

In many cases, hydroelectric energy or hydroelectric power plants' process to produce electricity can be compared to coal-fired power plants.[54] Hydropower presently accounts for 37% of total renewable electricity output and 7% of overall electricity generation in the United States.[55] The angle of inclination formed by a dam or diversion construction allows water to flow in and out on one side, therefore, generating electricity.[55]

The cost of hydropower can be considered very affordable, due to the fact that the source of electricity and energy come from moving water, states within the United States that have more moving water such as Washington and Oregon have more affordable electricity bills.[55] There are many advantages of hydropower, since it is fueled by water it is considered a clean source of energy. As well as it is a domestic source of energy, making it easier to reply to each state's sources rather than being reliant on international sources.[56] Hydropower accounted for 17% of global energy generation in 2020, making it the third largest generator following coal and natural gas. Hydropower's overall production has grown by 70% internationally in the previous 20 years, but its percentage of overall generation has remained steady due to the rise of wind, solar PV, coal, and natural gas.[57]

Hydroelectricity is mostly used for electricity production in the United States and in 2019 there were 1,460 utility scale hydropower facilities. These produced 274 billion kilowatt-hours. In 2019, it accounted for 6.6% of total electricity production and 38% of renewable electricity. The amount of electricity in the United States from hydropower has remained relatively the same since the 70's, however it's percentage has decreased due to more production from other sources. In 1950, 30% of total electricity production came from hydropower despite only 101 billion kilowatt-hours being produced.[58][59]

Hydropower has been used to produce electricity in the United States since 1880 when it was used to power the Wolverine Chair factory in Grand Rapids, Michigan.[59]

In 2019, the top five Hydroelectricity producing states produced 65% of the United States total hydroelectricity. This includes Washington state with 24%, California with 15%, New York with 11%, Oregon, with 11% and, Alabama with 4%. The largest hydroelectric power plant in the United States, which is also the largest overall power, is the Grand Coulee Dam built in Washington state in 1942 with a generating capacity of 6,809 Megawatts.[58]

Hydroelectric power is currently the largest producer of renewable energy in the U.S. It produced around 6.2% of the nation's total electricity in 2010 which was 60.2% of the total renewable energy in the U.S.[60] The United States is the fourth largest producer of hydroelectricity in the world after China, Canada, and Brazil. The Grand Coulee Dam is the 5th largest hydroelectric power station in the world.

Though Texas and California generate more wind and solar power, various other states generate more wind and solar power per capita. [61]

Solar[edit]

The United States has some of the largest solar farms in the world. Solar Star is a 579-megawatt (MWAC) farm near Rosamond, California.[62] The Desert Sunlight Solar Farm is a 550-megawatt solar power plant in Riverside County, California[63] and the Topaz Solar Farm, a 550 MW photovoltaic power plant, is in San Luis Obispo County, California.[64] The solar thermal SEGS group of plants in the Mojave Desert has a total generating capacity of 354 MW.[65] Rooftop solar has also become a growing contributor to overall solar power generation, with overall generated capacity at 26 GW in 2022 (around 1% of total generation capacity), with the states of California, Texas, Florida experiencing the fastest growth.[66]

A concentrating solar array (CSP) with thermal storage has a practical capacity factor of 33%[67] and could provide power 24 hours a day. Prior to 2012, in six southwestern states (Arizona, California, Colorado, Nevada, New Mexico, and Utah) the U.S. Bureau of Land Management (BLM) owned nearly 98 million acres or 400,000 square kilometres (an area larger than the state of Montana) that was open to proposals for solar power installations. To streamline consideration of applications, the BLM produced a Programmatic Environmental Impact Statement (PEIS). By the subsequent Record of Decision in October 2012, the BLM withdrew 78% of its land from possible solar development, leaving 19 million acres (77,000 km2) still open to applications for solar installations, an area nearly as large as South Carolina. Of the area left open to solar proposals, the BLM has identified 285,000 acres (115,000 ha) in highly favorable areas it calls Solar Energy Zones.[68] In Spain, with natural gas backups, CSP has reached a capacity factor of 66%, with 75% being a theoretical maximum.[69][failed verification]

The Shepherds Flat Wind Farm is an 845-megawatt wind farm in the U.S. state of Oregon.

Wind[edit]

U.S. wind power's installed capacity now exceeds 65,000 MW and supplies 4% of the nation's electric power.[70][71] Texas is firmly established as the leader in wind power development followed by Iowa and California.[72]

Final energy consumption[edit]

Consumption by sector[edit]

The U.S. Department of Energy tracks national energy consumption in four broad sectors: industrial, transportation, residential, and commercial. The industrial sector has long been the country's largest energy user, currently representing about 33% of the total. Next in importance is the transportation sector followed by the residential and commercial sectors.

Regional variation[edit]

2017 residential sector energy price estimates (U.S. dollars per million Btus) from the Energy Information Administration. States with residential sector energy price estimates higher than the United States as a whole in dark green.[76]
US household energy usage.png

Household energy use varies significantly across the United States. An average home in the Pacific region (consisting of California, Oregon, and Washington) consumes 35% less energy than a home in the South Central region. Some of the regional differences can be explained by climate. The heavily populated coastal areas of the Pacific states experience generally mild winters and summers, reducing the need for both home heating and air conditioning. The warm, humid climates of the South Central and South Atlantic regions lead to higher electricity usage, while the cold winters experienced in the Northeast and North Central regions result in much higher consumption of natural gas and heating oil. The state with the lowest per-capita energy use is New York, at 205 million BTU (216 GJ; 60 MWh) per year,[77] and the highest is Wyoming, at slightly over 1 billion BTU (1,100 GJ; 290 MWh) per year.[78]

Other regional differences stem from energy efficiency measures taken at the local and state levels. California has some of the strictest environmental laws and building codes in the country, leading its per-household energy consumption to be lower than all other states except Hawaii.

The land-use decisions of cities and towns also explain some of the regional differences in energy use. Townhouses are more energy efficient than single-family homes because less heat, for example, is used per person. Similarly, areas with more homes in a compact neighborhood encourage walking, biking and transit, thereby reducing transportation energy use. A 2011 U.S. EPA study found that multi-family homes in urban neighborhoods, with well-insulated buildings and fuel-efficient cars, use less than two-thirds of the energy used by conventionally built single-family houses in suburban areas (with standard cars).[79]

Electricity[edit]

The United States is the world's second largest producer and consumer of electricity. It generates 15% of the world's electricity supply, about half as much as China.[80]

Generation[edit]

Generation by source

The United States had a nameplate generation capacity of 1,213.05 GW and produced 3,987.83 TWh in 2021. Total generation has been flat since 2010. Net electricity imports were 39 TWh, or about 1% of sales. Historically, net imports have been between just under 0% to just over 1.5%. [81] [82]

Fossil fuels made up the majority of generation, with natural gas providing 38% and coal 23%. Petroleum provided less than 1%. Natural gas as a proportion of fossil fuels has been increasing since the 90's, with coal peaking around 2008 and natural gas becoming the top fossil fuel in 2016.

Nuclear provided 20%, a level consistent since about 1990. Nuclear surpassed coal in 2020 for the first time, as coal dipped to its lowest proportion in over 70 years.

Among renewables, wind and solar continued to expand, with wind exceeding hydro since 2019. Renewable use has doubled from 2010 to 2020, reaching 20% of total generation. [83]

The following table summarizes the electrical energy generated by fuel source for the United States grid in 2021. The table uses data from the Annual Energy Review. [85] Figures account for generation losses, but not transmission losses.

Generation by state[edit]

Generation by state and source

The following figures offer detail into the sources of generation used in each state.[88] Most often, natural gas is the largest source in a given state, with 22 states using it more than any other. Among renewable sources, 18 states use wind power more than any other.

Though not always the most prominent source, each state will use at least one source at a rate above the national average. Twelve states use nuclear power more than average, and California and Hawaii each use more solar and petroleum, respectively.

Texas contributes more to the grid than any other state, followed by Florida, Pennsylvania and California. On net, Pennsylvania exports the most power, while California imports the most.

Consumption[edit]

US Electricity Prices

Electric grid consumption in the U.S. was 3,806 TWh in 2021. Since 2010, total consumption has remained within 2% of this figure. Per capita consumption was 11.5 MWh in 2021, down 8% from its peak in 2007. [89]

Residential customers used 39%. Each month, the average customer used 886 kWh and paid $121 at an average rate of 13.7 cents/kWh. The commercial sector used 35% and industrial used 26% of the total. Transportation used less than half of one percent.[90]

System loss within the grid includes use in the generation process and transmission losses, as well as unaccounted loads. For 2021, this amounted to 203 TWh, or 5.3% of grid generation. Electricity used directly at the commercial or industrial level added 139 TWh, so total consumption was 3,945 TWh.[91]

Notes: 1 Gas includes natural gas and other gases. 2 Hydro excludes pumped storage (not an energy source, used by all sources, other than hydro). 3 Solar includes photovoltaics and thermal. 4 Bio other includes waste, landfill gas, and other. 5 Misc. includes misc. generation, pumped storage, and net imports. 6 Total includes net imports. 7 2021 data is from Electric Power Monthly and is preliminary.[94]

Electric generation, consumption and net imports[edit]

This is a list of U.S. states and the District of Columbia by annual net participation in the Electricity market of the North American power transmission grid. Data is from the Energy Information Administration for the year 2021.[95]. Because of trade with Canada and regional variations, this table does not assume that transmission losses are uniform and thus does not calculate sales for each state.
