據美國鉆井網站2022年8月10日報道，美國能源信息署（EIA）表示，與2019年相比，2020年美國能源產量創紀錄下降，主要是由于疫情大流行期間經濟活動低迷。  

EIA說，2020年懷俄明州的總能源產量下降幅度最大，減少了1264萬億熱能單位，主要是由于煤炭產量下降。根據EIA的數據，2020年美國7個州的年度能源產量出現了至少60年來最大的下降。

為了計算美國的總能源產量，并比較以不同物理單位（如桶、立方英尺、噸、千瓦時等）報告的不同類型的能源，EIA將能源轉換為常見的熱量單位，稱為英熱單位（Btu）。 EIA使用化石燃料當量來計算風能、水力、太陽能和地熱等不燃可再生能源的用電量。 

美國煤炭產量在2020年下降了創紀錄的25%，達到1965年以來的最低水平。2020年，由于幾座煤礦關閉，印第安納州、肯塔基州和懷俄明州的煤炭產量分別下降37%、33%和21%。

從絕對值來看，美國最大的煤炭生產州懷俄明州的煤炭產量下降超過1000萬億英熱單位，是所有州中下降最多的。2020年，亞利桑那州最后一座煤礦關閉，煤炭生產完全停止。

2020年，美國原油產量創紀錄地下降8%。在32個生產原油的州中，有29個州的原油產量下降，部分原因是疫情期間對運輸燃料的需求減少。一個顯著的例外是新墨西哥州，那里的原油產量增加216萬億英熱單位，比2019年增加11%。新墨西哥州在2021年成為美國第二大產油州。

2020年，美國投入市場的天然氣產量下降不到1%，原因是天然氣需求和價格在稍暖的一年有所下降。俄克拉荷馬州投入市場的天然氣產量下降300萬億英熱單位，該州頁巖產量下降近20%。在俄亥俄州，盡管2020年下降289萬億英熱單位（Btu），但該州投入市場的天然氣產量仍是2010年的31倍。  

2020年，美國可再生能源產量增長不到1%，其中太陽能產量增長19%，風能產量增長13%，但生物燃料產量下降10%，水電產量下降2%。2020年，加州的水力發電量下降45%，是所有州中降幅最大的，主要原因是大范圍的干旱。

2020年，美國年核能發電量下降2%，主要原因是馬薩諸塞州等兩個核電站關閉。

U.S. Energy Production Noted Record Drop In 2020

In 2020, energy production in the United States fell by record amounts compared with 2019, mostly due to decreased economic activity during the Covid-19 pandemic, the U.S. Energy Information Administration (EIA) said.

Wyoming had the largest drop in total energy production among the states, decreasing by 1,264 trillion thermal units, mostly due to decreased coal production. According to EIA, seven states saw their largest annual energy production decline in at least 60 years.

To calculate U.S. total energy production and to compare different types of energy reported in different physical units (such as barrels, cubic feet, tons, kilowatt-hours, etc.), the EIA converts sources of energy to common units of heat, called British thermal units (Btu). The EIA uses a fossil fuel equivalence to calculate the electricity consumption of noncombustible renewables for wind, hydropower, solar, and geothermal.

U.S. coal production fell by a record 25 percent in 2020 to its lowest level since 1965. Coal production during 2020 fell by 37 percent in Indiana, 33 percent in Kentucky, and 21 percent in Wyoming, as several coal mines closed.

In absolute terms, coal production in Wyoming, the nation’s largest coal producer, decreased by more than 1,000 trillion Btu, the most of any state. In 2020, coal production in Arizona stopped entirely with the closure of its last coal mine.

U.S. crude oil production fell by a record 8 percent in 2020. Production fell in 29 of the 32 states that produce crude oil, in part because of reduced demand for transportation fuels during the pandemic. One notable exception was in New Mexico, where crude oil production increased by 216 trillion Btu – an 11 percent increase from 2019. New Mexico became the nation’s second-largest crude oil-producing state in 2021.

The U.S. marketed natural gas production decreased by less than 1 percent in 2020, as natural gas demand and prices declined during a slightly warmer year. Marketed natural gas production in Oklahoma decreased by over 300 trillion Btu as shale production in the state fell by nearly 20 percent. In Ohio, despite a 289 trillion Btu drop in 2020, marketed natural gas production in the state was 31 times larger than in 2010.

U.S. renewable energy production increased by less than 1 percent in 2020, as solar production increased by 19 percent and wind by 13 percent, but biofuels fell by 10 percent, and hydropower by 2 percent. Hydroelectricity generation in California fell by 45 percent in 2020, the largest decline of any state, mostly because of extensive drought.

U.S. annual nuclear generation fell by 2 percent in 2020, mostly because of nuclear power plant closures in Massachusetts .
