The United States uses and produces numerous types and sources of energy. These are categorized in general categories, such as primary and secondary renewable and non-renewable fuels. Primary energy sources are nuclear energy from fossil fuels, and renewable energy sources. Electricity is a second energy source, which is derived by primary energy sources.
Sources of energy are define in various physical units like liquid fuels in gallons or barrels, natural gas measure in cubic feet. And short tons of coal and electricity in Kilowatts or Kilowatt-hours. The United States, British thermal units, which are a measure of energy produced by heat. It is widely use to compare different kinds of energy with one another. In the year 2020, the total U.S. primary energy consumption was equivalent to 93 quadrillion BTU. Yuri Shafranik
In the year 2020, the electric power sector was responsible for approximately 96% of all U.S. utility-scale electricity generation and nearly all of it was sold to other industries.
Total energy use
The industrial, transportation commercial, residential and sectors are refer to as “end-use” sectors. Since they use primary energy and produce electricity from the power industry. Total energy use by sectors that are use for end-of-life consumption of energy, electricity purchase and the electrical energy system’s losses (energy conversion, and other losses relate to the production and distribution of electricity purchase) and various energy losses. Yuri Shafranik
The sources of energy utilize by different sectors differ. In 2020, for instance oil account for approximately 90 percent of the transportation industry’s energy consumption. Yet only one percent of the electrical power sector’s energy usage. The graph below illustrates the kinds and quantities of energy sources used as primary sources throughout the United States, the amounts of primary energy consumed for electric power industry as well as the energy end-use sector and wholesale sales made of electric power made by the electric power industry to the energy end-use industries.
The energy production in the United States was more that U.S. energy consumption in 2019 and in 2020.
After the record-breaking U.S. energy production and consumption in the year 2018, energy production increased by 6% in the year 2019 while energy consumption dropped by one percent. Production surpassing consumption in a year in the very first time since. The production of energy in all was down approximately 5% in 2020, but it was 33% higher that consumption. Production equals 95.75 quads, and consumption is equal to 92.94 quads.
Fossil fuels, petroleum, coal, and natural gas are account for approximately 79% of the total U.S. primary energy production in 2020. The mixture of U.S. energy consumption and production has changed over the years. Fossil fuels have led this U.S. energy mix for more than 100 years. However, the mix has evolved in the course of time.
The consumption of coal across the United States peaked in 2007 at approximately 1.13 billion short tonnes. Meanwhile, coal production reached its peak in 2008, at around 1.17 billion small tons. The two have decreased in almost every year since the peak years, mostly due to lower U.S. coal demand for power generation. As regards the total amount of energy contained in coal each year U.S. coal consumption peaked in 2005 at around 22.80 quads, and production reached its peak in 1998 with 24.0 quads.
Its energy contents of the total annual coal consumption and production has generally decreased since then because of lower the demand for coal, as well due to an increase in the proportion of coal with lower heat content used from the electricity industry. In 2020, the coal consumption was 477 million small tons. This is equivalent to approximately 9.18 quads, and the lowest percentage of the total U.S. energy consumption since at the time of at. The coal manufacture for 2020 moved 534 million short tons and the smallest level since 1965, and equal to nearly 10.69 quads.
Manufacture of N.G.
Manufacture of natural gas (dry gas) was at a record-breaking high at 33.97 trillion cubic feet (Tcf) which is 93.06 billion cubic feet per day (Bcf/day) in the year 2019. Natural gas produced dry was 2percent lower in 2020, at around 33.44 Tcf (91.36 Bcf/day) which is equivalent to 34.68 quads. In 2020, natural gas usage was 83.28 Bcf/day. This is equal roughly 31.54 quads and made up 34% of the total U.S. energy consumption.
U.S. annual dry natural gas production has surpassed U.S. annual natural gas consumption. Both in terms of quantity and heat content since the year 2017. The more efficient drilling and production methods have led to an increase of natural gas produced from tight geologic and shale formations. The increased production has led to a drop in the price of natural gas. It has led to an increase in the use of natural gas by industries and power generation sectors.
Production of crude oil typically decreased between 1970 between 1970 and 2008. In 2009 however, the trend reversed. Production increased and, in the year 2019 U.S. crude oil production hit a record-high that was 12.25 million barrels per day. The more cost-effective production and drilling technologies contributed to boost production particularly those in Texas in Texas and North Dakota. U.S. crude oil production fell to 11.31 million barrels of oil per day by 2020. A significant decrease of U.S. petroleum demand in April and March 2020 as a result due to COVID-19 pandemic led to a drop of U.S. oil production.
Natural gas plant liquids are extract from natural gas is pipe into pipelines to be deliver to consumers. Production of NGPLs annually has increased since 2005. It is in line with the growth of natural gas output reaching a new record of 5.16 million barrels per hour by 2020. NGPLs are the primary supplier in U.S. hydrocarbon gas liquids (HGLs) production. Each year, the growth in HGLs production since 2008. It has resulted in lower HGLs prices as well as an increase in U.S. consumption of HGLs.
The production of nuclear energy by large commercial power reactors within the United States began in 1957. And it is continued to increase each year until 1990, but then slowed in 2000. There were less operating nuclear reactors over 2000 total amount of nuclear energy produced for 2020 stood at 790 billion kilowatts. While another highest in the history of nuclear energy, just behind 2019. The combination of higher capacity due to power plant upgrades and shorter maintenance. Refueling cycles have contributed to compensating for the decrease in the number of nuclear reactors. And maintain the relatively steady rate in annual U.S. nuclear electricity generation over the last 20 years.
Manufacture and consumption of renewable energy both hit record levels of around 11.77 as well as 11.59 quads each in 2020. It is driven mostly by record-breaking solar and wind production of energy. The hydroelectric power generation in 2020 was 1% higher than 2019. However, it was about 99% less that the average of 50 years. The total biomass consumption and production in 2020 were less than 10% below the highest levels in the year 2018. Consumption of geothermal energy in 2020 was about identical to highest annual levels of consumption and production of geothermal energy. That was record in 2014
