A recent Power Research Center survey showed that the US (77 percent), in general, believes it is more necessary than to generate more coal, oil and other fossil fuels to develop alternative sources of energy such as solar and wind. It raises the question: how does the US meet its huge resource needs and what has changed it if anything?
As you might suspect, the answer is quite complicated. The use of solar and wind power has grown at a rapid rate over the past decade or so, but by 2018 the energy used in the United States represented less than 4%.
The overall energy use in the U. S., from lighting, heating and cooking meals to fueling plants, driving cars and smartphones, reached 101.2 B tu in 2018, the highest level since data collection began in 1949, according to the Federal Energy Information Administration (EIA).
How all of this achieved
The energy industry in the US uses about 38% of all Btu’s energy sources (electrical utilities and independent power generators) to convert the power industry into electricity and export it to the rest of the economy. The energy industry uses the largest energy share
Since the turn of the XXI century, however, in 2018, per capita use of energy in the USA has been a downward trend. In the year 2000, each American used an average of around 349.8 m Btu. In 2017, the lowest in five decades was 300.5 million Btu. Nonetheless, in 2018 energy consumption per capita was up to Btu 309.3 million. (In 1979, energy consumption per capita reached Btu 359 million)
Seen differently, the US economy has slowly become less energy-intensive since the end of World War II. Each dollar of the real gross national product was made by 15,175 Btu in 1949. By 2018, it took 5,450 people, down by 64%. The method is still unreliable, however: in 2018 almost two thirds (like heat emissions from cars and furnaces) of all the electricity used is calculated by the Lawrence Livermore National Laboratory.
Today, the US fulfills almost all its energy needs through domestic production. In 2018 net imports, mostly petrol, accounted for less than 4 percent, relative to 26 percent a decade earlier, of the total US energy supply.
According to the EIA reports, in the first 10 months of 2019, the United States had pumped almost 3,7 billion barrels of crude oil, which is over 2 billion above that of 2009.
New technologies, especially fracking and horizontal boiling, have been driving the dramatic rise in domestic oil and gas production to allow companies to access deeper reserves that had been too costly to tap. As a result, Saudi Arabia and Russia, respectively, became the largest petroleum and gas producer worldwide in 2018. U.S. solar electricity has increased, coal production has fallen since 2000.
