Fossil fuels are carbon-rich energy sources formed from the remains of prehistoric organisms. They have been used to power economies for over 150 years and continue to supply about 80% of the world's energy. The dominant fossil fuels are coal, oil, and natural gas, which are burned to generate electricity, heat, and power transportation. The transportation sector is the largest consumer of fossil fuels, with over 94% of the fuel used for transportation being petroleum-based. Other sectors that consume fossil fuels include industry, electricity generation, and commercial and residential. The industrial sector uses fossil fuels for process heating, generating electricity, and as feedstocks to create products such as plastics and chemicals. While fossil fuels have been key to industrialization and economic growth, they have severe environmental and health impacts, contributing to climate change, air pollution, and health issues. As a result, there is a growing movement to transition towards renewable and sustainable energy sources.

Transportation
The transportation sector is heavily reliant on fossil fuels, with gasoline being the dominant transportation fuel in the United States. Gasoline, including motor and aviation gasoline, accounted for 52% of total energy consumption by the U.S. transportation sector in 2022. Distillate fuels, mainly diesel, accounted for 23%, while jet fuel accounted for 12%. Over 94% of the fuel used for transportation is petroleum-based, resulting in direct emissions. Other fossil fuels used in transportation include natural gas and propane, which are used in cars, buses, trucks, and ships.
The transportation sector is a major contributor to greenhouse gas emissions, with CO2 emissions from transport rebounding in 2022 to near 2019 levels. Aviation was responsible for much of this increase as air travel rebounded from pandemic lows. However, electric vehicles (EVs) are gaining popularity, with over 10 million cars sold globally in 2022, reaching 14% of all car sales. Policies and regulations are being implemented to encourage the adoption of EVs and biofuels, such as the Inflation Reduction Act in the United States and the European Union's Green Deal Industrial Plan.
To align with net-zero emission targets, the transportation sector needs to reduce its carbon intensity. This includes implementing policies that promote less carbon-intensive travel options, such as walking, cycling, and public transport, as well as more efficient technologies like electric cars and trucks. In addition, shipping and aviation must focus on tightening carbon intensity standards and adopting low-emission fuels.
The transition away from fossil fuels in the transportation sector is crucial for mitigating climate change and improving air quality. While progress is being made, continued efforts and investments in alternative fuels and technologies are necessary to reduce the sector's environmental impact.

Electric power
Fossil fuels have been a major source of energy for the electric power sector. In 2023, about 60% of electricity generation in the United States was from fossil fuels, including coal, natural gas, petroleum, and other gases. The electric power sector, along with the transportation sector, has historically consumed more than half of the fossil fuel-produced energy in the country.
Coal is the most widely used fossil fuel for electricity generation. It is a fossilized plant material preserved by burial in sediments and changed by geological forces that compact and condense it into a carbon-rich rock. Coal has been used as a primary energy source for electricity generation due to its accessibility and affordability. However, there has been a declining trend in coal consumption due to its environmental impact, with 2017 seeing the lowest level of coal consumption in the electric power sector since 1982.
Natural gas is the third most widely used fuel for electricity generation. It is considered the cleanest fossil fuel, producing only half as much carbon dioxide (CO2) as coal when burned. The shift from coal to natural gas has contributed to the reduction in carbon emissions from the electric power sector. The increased efficiency of natural gas-fired power plants has also played a role in reducing fossil fuel consumption for electricity generation.
Petroleum-derived fuel oil is the most widely-used liquid fuel for power generation. It is classified into distillate and residual fuel oils, with different characteristics and applications. Distillate fuel oils, such as kerosene and diesel, are commonly used in domestic and small commercial settings, while residual fuel oils are highly viscous and require preheating for combustion.
The electric power sector's consumption of fossil fuels has been on a downward trend since 1994. This trend is driven by a decrease in coal and petroleum use, partially offset by an increase in natural gas consumption. Improvements in electricity-generating technology have also contributed to producing electricity more efficiently while reducing fossil fuel consumption. As a result, carbon dioxide emissions from the electric power sector have decreased, with 2017 seeing the lowest emissions since 1987.

Industrial sector
Fossil fuels have been a fundamental driver of technological, social, economic, and development progress since the Industrial Revolution. The industrial sector uses fossil fuels for a variety of purposes, including electricity generation, industrial motors and machinery, lights, computers, and office equipment. Some industries, like paper mills, use combined heat and power plants that burn natural gas, coal, or biomass from their industrial processes to generate electricity and provide process heat.
Within the industrial sector, manufacturing accounts for the largest share of annual energy consumption. In 2018, chemical manufacturers accounted for about 70% of total nonfuel energy feedstocks use by manufacturing and for 22% of total U.S. manufacturing sector fuel and nonfuel energy/feedstock use. Feedstocks (raw materials) are used to make products such as plastics and chemicals. Coal, a fossil fuel, accounted for 7% of the total manufacturing energy feedstock use in 2018, with 60% used by primary metals manufacturers (iron and steel) and the rest by petroleum and coal products manufacturers.
The industrial sector also includes mining, construction, and agriculture. Mining involves the extraction of minerals, non-mineral products like stone and gravel, coal, oil, and natural gas. Agriculture includes farming, fishing, and forestry.
While the industrial sector has traditionally relied on fossil fuels, there is a growing trend towards renewable energy sources. Some manufacturers produce electricity with solar photovoltaic systems, and some industrial facilities sell the electricity they generate. Additionally, biomass from agriculture, forestry, and lumber milling can be used as a renewable energy source.
The transition to renewable energy sources in the industrial sector is important given the negative impacts of fossil fuels on health and the environment. Fossil fuels are the largest driver of global climate change and contribute significantly to air pollution and carbon dioxide emissions.

Manufacturing
The manufacturing sector is the largest consumer of industrial energy. Manufacturers consume two types of energy sources: fuel and nonfuel. Fuel consumption involves using combustible energy sources to generate electricity and heat, while nonfuel sources are feedstocks (raw materials) used to make products.
In 2018, fuel use accounted for about 68% of total energy use by US manufacturers, with natural gas being the largest manufacturing nonfuel energy source. Natural gas is a major feedstock for making fertilizers. Other fossil fuels used include coal, which accounted for 7% of total manufacturing energy feedstock use in 2018, and petroleum, which is the greatest source of primary energy consumption in the US.
The manufacturing sector emits carbon dioxide and other greenhouse gases by burning fossil fuels and through certain industrial processes. In 2021, the sector was responsible for 12% of US greenhouse gas emissions, with 75% of those emissions from burning fuel to create heat. Fossil fuels are also used as raw materials to create new products, such as natural gas for fertilizer production.
The transition away from fossil fuels in the manufacturing sector is challenging due to the heavy integration of the fossil fuel industry into the global economy and the high costs of low-carbon technologies. However, progress is being made, with renewable energy consumption in the US projected to increase by 2050.

Agriculture
Fossil fuels are used in various sectors, including transportation, electricity generation, and manufacturing. One sector that relies heavily on fossil fuels is agriculture.
The food system, which includes agriculture, accounts for at least 15% of global fossil fuel use annually, emitting as many greenhouse gases as all EU countries and Russia combined. This significant contribution to emissions has led to calls for a transition to more sustainable practices. Agroecological and regenerative approaches, such as agroecology, can help decouple food production from GHG emissions. Implementing renewable technologies for cooling, heating, and drying agricultural products can also bring benefits.
However, shifting away from fossil fuels in agriculture is complex. The fossil fuel industry is heavily integrated with the agricultural sector, and large corporations have vested interests in maintaining the status quo. Additionally, the availability and price of fossil fuels, such as oil, natural gas, and coal, influence agricultural practices and energy inputs. Nevertheless, with the growing recognition of the climate crisis and the negative impacts of fossil fuels, there is an increasing urgency to optimize energy use and reduce emissions in the agricultural sector.
