Oil-fired power stations generate electricity by burning oil. They are built and operated similarly to coal-fired and natural gas-fired power plants.
Is it necessary to use oil to generate electricity?
Coal or oil-fired power plants generate heat, which is then used to generate steam, which drives turbines that generate electricity.
Why isn’t oil used to generate electricity?
The energy system evolved during the twentieth century from one in which fossil energy was used directly to one in which a significant share of fossil fuels is used to create electricity. The percentage of fuel utilized in power generating varies. Because oil, an energy-dense liquid, is so well-suited to transportation, only a small portion of it is used to create power; by comparison, nearly 63 percent of coal produced globally is used to generate electricity. Nuclear and hydroelectric generation, for example, are major aspects of the system in many locations since they do not rely on fossil fuels. Fossil fuels, on the other hand, continue to be the backbone of the electrical system, accounting for 64 percent of worldwide supply today.
How much electricity is generated by oil?
In 2021, the yearly average amounts of coal, natural gas, and petroleum fuels used by US electric utilities and independent power providers to create a kilowatthour (kWh) of electricity were:1
Electric utilities and independent power producers in the United States generated the following yearly average number of kWh per amount of coal, natural gas, and petroleum fuels utilized for electricity generation in 2021:1
The figures above are based on preliminary data from the Electric Power Monthly for 2021, which was published in April 2022, as well as simple averages of national-level annual statistics for electric utilities and independent power providers. They are the annual average amounts for the majority of the electricity generated for sale in the United States, but they do not include power generated in the commercial and industrial sectors. Fuel use for useable thermal output in combined heat and power plants is not included in the fuel consumption data used for the above quantities.
Actual numbers for a particular generator or power plant may differ significantly from those listed above. The amount of fuel consumed to create electricity is determined by the generator’s efficiency (or heat rate) and the heat content of the fuel. The types of generators (primary movers), the type and heat content of fuels, power plant emission controls, and other factors all affect power plant efficiencies (heat rates).
The amount of fuel consumed to generate a kilowatthour (kWh) of electricity can be calculated using two formulas:
- Heat rate (in British thermal units per kWh) divided by Fuel heat content = Amount of fuel used per kWh (in Btu per physical unit)
- Fuel heat content (in Btu per physical unit) divided by Heat rate = Kilowatthour created per unit of fuel used (in Btu per kWh)
The following are some of the data sources available from the US Energy Information Administration (EIA) for those calculations:
- The average quality of fossil fuel receipts for the electric power industry is shown in Table 7.3. ( xls )
Appendices providing fuel heat contents, electricity heat rates, and conversion factors are included in the Monthly Energy Review.
On a national and state level, as well as at individual power plants, the EIA releases monthly and annual data on the quantity of electricity generated and associated fuel consumption by electricity producers. This information can also be used to compute fuel use per kWh of electricity generated, as well as kWh generation per unit of fuel consumption.
- Data on total power generation in the United States (Table(s) 7.2) and electricity generation fuel consumption (Table(s) 7.3).
- Historical power data files at the state level, including annual and monthly electricity generation and fuel usage.
- Data on fuel consumption and electricity generation at individual power plants in the United States, broken down by fuel/energy source.

Other FAQs about Oil/Petroleum
- Is there information from the EIA on the rail movement (transport) of crude oil, petroleum products, gasoline ethanol, and biodiesel?
- A kilowatthour of electricity is generated using how much coal, natural gas, or petroleum?
- Does the EIA provide state-by-state estimates or projections for energy output, consumption, and prices?
- Is the EIA aware of any unplanned disruptions or shutdowns of energy infrastructure in the United States?
- What percentage of the crude oil produced in the United States is used in the country?
Is power generated from fuel oil?
Fuel oil is used in power plants to generate electricity in some parts of the United States, albeit it accounts for less than 1% of overall energy generation. These power stations are typically smaller than coal, natural gas, or nuclear power plants.
What is the process of producing electricity?
According to the US Energy Information Administration, natural gas, nuclear energy, and coal generated the majority of the country’s electricity in 2020.
Renewable energy sources such as wind, hydropower, solar power, biomass, wind, and geothermal power are also used to generate electricity. Renewable energy sources accounted for over 20% of the country’s electricity in 2020.
A turbine generator set transfers mechanical energy into electrical energy to generate electricity. The heat produced by natural gas, coal, nuclear fission, biomass, petroleum, geothermal, and solar thermal energy is utilized to make steam, which drives the turbine blades. Turbine blades are directly moved by flowing wind and water in the case of wind and hydropower, respectively. Solar photovoltaic panels use semiconductors to convert sunlight directly to electricity.
The amount of energy produced by each source is determined by the fuels and energy sources available in your area. See the section on emissions for further information. The Energy Information Administration of the United States Department of Energy has more information on power production.
What percentage of oil is used in solar panels?
This indicates that 17,208,000 barrels of oil per day would be required to produce the same amount of energy as the current global power production (about 87 TWh/day) generated by solar panels.
Because the present global daily production is just 85 million barrels, it would take nearly three years of global oil production to produce enough solar panels to create the amount of electricity we currently use!
Is it possible to live without oil?
Without oil, the flow of goods to stores would halt, and shelves would swiftly empty, according to Johansen. People would be unable to get to and from work, and therefore life would come to a halt.
“Service providing would come to a halt,” he predicts. “That’s terrible enough, but blocking the flow of products has far more serious effects.
“If we’re going to start growing carrots in flower pots or keeping pigs and hens in the back garden, it’ll take some time to adjust.”
Agriculture might continue on a smaller scale, using traditional methods and a more seasonally focused, local food supply.
According to Johansen, converting to a life without oil for fundamental daily needs would take at least 10-20 years.
He points out that even the UN’s international panel on climate change’s scenarios for the 1.5C goal incorporate significant oil and gas consumption up to and beyond 2050.
How much oil is there left on the planet?
The world’s proven reserves are equal to 46.6 times its yearly consumption. This means it will run out of oil in around 47 years (at current consumption levels and excluding unproven reserves).
Is oil running out?
We will, without a doubt, run out of oil. Despite the numerous mass extinctions that have happened over the course of Earth’s vast history, not every fossilized living form has been converted to petroleum, coal, or natural gas. All of those fossil fuels are nonrenewable and irreplaceable, so we won’t be able to replace them once they’re gone. In many senses, we’ll be out of luck until we find a petroleum substitute at some point.
How much of the world’s electricity comes from oil?
In 2019, coal remained the most common fuel for power generation, accounting for 37% of worldwide energy output, putting it 10% ahead of renewables. Since the mid-2000s, coal’s share of electricity production has fluctuated around 40%, until starting to decline in 2015 as renewables grew rapidly. In 2013, renewables overtook natural gas as the leading source of electricity, and the gap has continued to widen. Renewables provided over 27% of global electricity in 2019, three points more than natural gas (24 percent ). Nuclear power has remained stable at roughly 10% for the past eight years, whereas oil produced less than 3% of global electricity in 2019.
