Answer:
HERE IS YOUR ANS!!
Explanation:
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.
Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.
Fossil fuels are the largest sources of energy for electricity generation
Natural gas was the largest source—about 38%—of electricity generation in 2019. Natural gas is used in steam turbines and gas turbines to generate electricity.
Coal was the second-largest energy source for electricity generation in 2019—about 23%. Nearly all coal-fired power plants use steam turbines. A few coal-fired power plants convert coal to a gas for use in a gas turbine to generate electricity.
Petroleum was the source of less than 1% of electricity generation in 2019. Residual fuel oil and petroleum coke are used in steam turbines.
Distillate—or diesel—fuel oil is used in diesel-engine generators. Residual fuel oil and distillates can also be burned in gas turbines.

2005
● coal: 2,013 billion kilowatthours
● natural gas: 761 billion kilowatthours
● nuclear: 782 billion kilowatthours
● renewables: 358 billion kilowatthours
● petroleum and other: 142 billion kilowatthours
Nuclear energy provides one-fifth of electricity
Nuclear energy was the source of about 20% of electricity generation in 2019.
Nuclear power plants use steam turbines to produce electricity from nuclear fission.
Renewable energy sources provide an increasing share of electricity
Many renewable energy sources are used to generate electricity and were the source of about 17% of total electricity generation in 2019.

Hydropower plants produced about 7% of total electricity generation and about 38% of electricity generation from renewable energy in 2019. Hydropower plants use flowing water to spin a turbine connected to a generator.
Wind energy was the source of about 7% of total electricity generation and about 42% of electricity generation from renewable energy in 2019. Wind turbines convert wind energy into electricity.
Biomass was the source of about 1% of total
electricity generation in 2019.
Biomass is burned directly in steam-electric power plants, or it can be converted to a gas that can be burned in steam generators, gas turbines, or internal combustion engine generators.
Solar energy provided about 2% of total electricity in 2019. Photovoltaic (PV) and solar-thermal power are the two main types of solar electricity generation technologies. PV conversion produces electricity directly from sunlight in a photovoltaic cell. Most solar-thermal power systems use steam turbines to generate electricity.
Geothermal power plants produced about 0.5% of total electricity generation in 2019. Geothermal power plants use steam turbines to generate electricity.
