The three major categories of energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy.
Although the terms "electricity" and "energy" are often used interchangeably, it''s important to understand that electricity is just one component of total energy consumption. Let''s take a look at electricity data. This interactive chart shows the amount of electricity generated by a country each year.
While the Energy Institute (EI) provides primary energy (not just electricity) consumption data and it provides a longer time-series (dating back to 1965) than Ember (which only dates back to 1990), EI does not provide data for all countries or for all sources of electricity (for example, only Ember provides data on electricity from bioenergy).

In 2022, about 60% of U.S. utility-scale electricity generation was produced from fossil fuels (coal, natural gas, and petroleum), about 18% was from nuclear energy, and about 22% was from renewable energy sources. The percentage shares of utility-scale electricity generation by major energy sources in 2022 were:

The power generation unit is a process in which a pump, turbine, heater, and two heat exchangers are used. In this cycle, carbon dioxide is used to generate power. Liquid carbon dioxide flow (37) enters the P-3 pump at −11.8°C and a pressure of 26.05 bar and exits with a pressure equal to 240 bar.

Power generating units. Many types of power generating plants are in use and possible for the future, including steam plants fueled by coal, oil, or gas, nuclear plants, hydro plants and plants which use renewable energy. Most types of power generating units can be grouped by prime mover – the type of device that drives the electric generator.
Projected Costs of Generating Electricity 2020 – Analysis
This report includes cost data on power generation from natural gas, coal, nuclear, and a broad range of renewable technologies. For the first time, information on the costs of storage technologies, the long-term operation of nuclear power plants and fuel cells is also included.
Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery ( transmission, distribution, etc.) to end users or its storage, using for example, the pumped-storage method.
