Detailed explanation-1: -The electricity that we use is a secondary energy source because it is produced by converting primary sources of energy such as coal, natural gas, nuclear energy, solar energy, and wind energy, into electrical power.

Detailed explanation-2: -Primary energy sources include fossil fuels (petroleum, natural gas, and coal), nuclear energy, and renewable sources of energy. Electricity is a secondary energy source that is generated (produced) from primary energy sources.

Detailed explanation-3: -Electricity is a secondary form of energy.

Detailed explanation-4: -Primary energy is the energy contained in raw fuels while secondary energy sources are derived from primary energy. Secondary energy is the energy contained in raw fuels while primary energy sources have been processed. Primary energy sources are the least clean while secondary energy sources are renewables.

Detailed explanation-5: -According to the U.S. Energy Information Administration, most of the nation’s electricity was generated by natural gas, nuclear energy, and coal in 2020. Electricity is also produced from renewable sources such as wind, hydropower, solar power, biomass, wind, and geothermal.
