Fossil fuels are fossilized plants and animals. They form three main fuel sources: oil, coal and natural gas. These three fuel sources are the primary sources used to meet global power and energy needs. Because they are not renewable, they will eventually run out. Fossil fuels are extracted and traded on global commodity markets and have been subject to global price volatility since the 1960s. Fossil fuel prices tend to be high in favor of oil-producing countries. Obviously, we saw this volatility more recently when oil prices fell in the summer of 2014, but are now slowly recovering. The growing global demand for renewable forms of energy is challenging the dominant position of fossil fuels in the world.
This infographic shows the reasons for the rise of renewable energy and how it competes with demand for crude oil in particular, and the growing investment in renewable energy around the world.
In conclusion, changes in fossil fuels and renewables should be considered with a view to the future as fossil fuels are gradually running out. Renewable energy sources are on the rise and will certainly overtake fossil fuels today.

A recent Pew Research Center survey found that a majority of Americans (77%) would rather develop alternative energy sources such as solar and wind than produce more coal, oil and other fossil fuels. The question arises: how?
As you can imagine, the answer is complicated. The use of solar and wind energy has grown rapidly over the past decade, but in 2018 these energy sources accounted for less than 4% of all energy used in the United States (this is the most recent year for which data is available). Our data shows that most of the energy used in the United States comes from coal, oil, and natural gas. In 2018, these ‘fossil fuels’ provided about 80% of the country’s energy needs, slightly less than 84% a decade ago. Coal use has declined in recent years, but natural gas use has soared, with oil’s share of the country’s energy supply fluctuating between 35% and 40%.
From lighting and heating homes to cooking, fueling factories, driving and using smartphones, total energy consumption in the United States reached 101.2 thousand Btu in 2018, according to the federal government, an increase from 1949. It reached its highest level since the start of data collection. .Energy Information Administration (EIA).
(Abbreviation for British Thermal Unit, Btu is commonly used in the energy industry, not to mention the appliance sector, as a general scale for measuring and comparing different types of energy. 1 Btu is one pound of the amount of energy required to heat water, equal to about 1,055 metric joules at 1 degree Fahrenheit at sea level, or the heat released from burning a match in a standard wood kitchen.)
It is estimated that the United States is the second largest consumer of energy after China. How the United States acquires and uses energy, and how these trends have changed recently, as public concern about climate change mounts and energy policy becomes a key topic in political campaigns this year.
This report is based primarily on data collected by the Energy Information Administration, the statistical division of the United States Department of Energy. It also cites a study from the Pew Research Center examining Americans’ views on climate and energy policy. In October 2019, this survey interviewed 3,627 members of the Center’s American Trends Panel’s online survey panel. These are the questions and answers of the survey: The research method is as follows.
About 38% of all this Btu went to the energy industry (utilities and independent power generators), converted to electricity and sent back to the rest of the economy. Transport accounts for about 28% of total energy consumption, followed by industry (23%), residential (7%) and commercial (less than 5%).
Per capita energy use in the United States has been on a declining trend since the early 2000s, but recovered in 2018. By 2017, it had fallen to 305 million Btu, its lowest level in 50 years. However, in 2018, per capita energy consumption rose to 309.3 million Btu. (Per capita energy use peaked at 359 million Btu in 1979.)
From another perspective, the US economy has steadily become less energy-intensive since the end of World War II. In 1949, it took 15,175 Btu to produce one dollar of real GDP. It cost 5,450 in 2018, down 64%. However, the system still has many inefficiencies. Lawrence Livermore National Laboratory calculated that about two-thirds of all energy used in 2018 was wasted (such as heat dissipation from vehicles and furnaces). In addition, only 34.5% of the energy used in the power sector reaches the end user as electricity. The rest is lost in the production, transport and distribution of electricity.
Today, the United States supplies almost all of its energy needs with domestic production. Net imports, primarily oil, accounted for less than 4% of total US energy supply in 2018, up from 26% a decade ago.
In the first 10 months of 2019, the United States produced nearly 3.7 billion barrels of crude oil, according to EIA data. That is more than 2 billion barrels more than in the same period in 2009. A quarter of American energy production. Natural gas, which accounted for about a third of total energy production in 2018, is also growing at a breakneck pace, from 21.7 trillion cubic feet in the first nine months of 2009 to 33.6 trillion cubic feet in the same period of 2019. has reached a trillion cubic feet.
The dramatic increase in domestic oil and gas production has led to new technologies, most notably fracking and horizontal drilling. This has given companies access to underground depots that were previously too expensive to use. As a result, in 2018, the United States overtook Saudi Arabia and Russia to become the world’s largest producer of both oil and gas.
Coal, on the other hand, has fallen sharply since its peak in 2008 when nearly 1.2 billion tons were mined. Nearly all coal in the United States (about 93% in 2018, according to EIA data) is used for power generation. However, as a Brookings Institution report points out, US electricity demand is stagnating, natural gas prices are falling as production increases, and until recently government policy has largely focused on wind and solar energy. a light one. In 2018, the share of coal in total domestic energy production was only 16%, less than half the share ten years ago. In the first nine months of 2019, 540 million tons were extracted,
