As of 2006, the country's energy consumption had increased more rapidly than domestic energy production over the last 50 years in the nation (when they were roughly equal). This difference was largely met through imports.Ristinen, Robert, A. Energy and the Environment. Malloy, 2006. Print. Not included is the significant amount of energy used overseas in the production of retail and industrial goods consumed in the United States. According to the Energy Information Administration's statistics, the annual per-capita energy consumption in the U.S. has been somewhat consistent from the 1970s to the present time. The average was about per person from 1980 to 2010. One explanation suggested that the energy required to increase the nation's consumption of manufactured equipment, cars, and other goods has been shifted to other countries producing and transporting those goods to the U.S. with a corresponding shift of green house gases and pollution. Meanwhile any gains made by increasing energy efficiency were at least partially consumed by the

History

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

. 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. 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. As of 2009, United States per-capita energy use had declined to , 12% less than 2000, and in 2010, to levels not seen since the 1960s.

Primary energy consumption

Primary energy use in the United States was or about per person in 2009. Primary energy use was 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 emissions about 10% in 2009 compared to 2004. In 2020, the U.S as a whole produced 87.79 exajoules of energy.

fuel reduction initiatives, as well as natural disasters. 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. 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. 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. 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.


Petroleum

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. As the 20th century progressed,

s, and the government has responded to oil shocks in several ways. 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. 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,

was the largest source of energy production in the United States in 2016, representing 33% of all energy produced in the country. 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 , a 5.4% increase over 2014, and a 52% increase over the production of per day in 2005. Because of the greater supply, consumer prices for natural gas are significantly lower in the United States than in Europe and Japan. 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

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.


Coal

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. Electric utilities buy more than 90% of the coal consumed in the United States. 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.

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.

. 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 per year, and the highest is Wyoming, at slightly over per year. 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).

State electric characteristics

Individual states have very diverse electric generation systems, and their new initiatives to expand their generation base are equally diverse. Coupled with consumption disparages, it leads to a mix of "have" and "have not" electric energy states. Using the data from the U.S. DOE Energy Information Administration/Electric Power Annual 2017 files. Data was obtained from the most recent DOE Energy Information Agency (EIA) full year files. Full use of the excellent EIA data browser permits easy access to the plethora of data available.

Importing states

The following table, derived from data mined from Electric Power Annual, identifies those states which must import electrical energy from neighboring states to meet their consumption needs. Each state's total electric generation for 2018 is compared with the state's consumption, and its share of the system loss and the difference between the generated electric energy and its total consumption (including its share of the system loss) is the amount of energy it imports. For Hawaii, total consumption equals generated energy. For the other states, multiplying their direct consumption by 1.082712997 (4168280574/3849848100), results in the United States' supply (including net imports) being equal to its total consumption.


Exporting states

The following table, derived from data mined from Electric Power Annual, identifies those states which generate more electrical energy than they need to meet their consumption needs. They supply those that need additional energy. Each state's total electric generation for 2018 is compared with the state's consumption, and its share of the system losses and the difference between the generated electric energy and its total consumption (including its share of the system losses) is the amount of energy it exports. For Hawaii, total consumption equals generated energy. For the other states, multiplying their direct consumption by 1.082712997 (4168280574/3849848100) results in the United States' supply (including net imports) being equal to its total consumption usage. A state's exported energy is determined by subtracting the state's total consumption from its generation.

Trends and projections

In 2015, electrical energy usage in the United States was 1.6% more than in 2005 and 1% less than the peak in 2007. Per-capita consumption has decreased about 7% since its peak in 2007 and every year since has shown a decrease in individual consumption. Conservation efforts are helping. At least, for the next decade, coal, natural gas, and nuclear will remain the top three fuels for electric energy generation in the United States. Coal will continuously decrease its contribution, with natural gas increasing its contribution. Nuclear will have some downs (decommissionings) and ups (new online plants) but probably remain about constant. Hydro will maintain. Petroleum will continue to decrease in importance. Wind and solar will continue to grow in importance; their combined generation was 5.29% of U.S. electric generation for 2015 or 5.20% of total U.S. consumption. 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 per person. In the 20th century this increased to around ( per person per year in 1981). A concentrating solar array (CSP) with thermal storage has a practical capacity factor of 33% 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 (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 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 in highly favorable areas it calls Solar Energy Zones. In Spain, with natural gas backups, CSP has reached a capacity factor of 66%, with 75% being a theoretical maximum.
