Yes, electricity is a secondary source of energy because it is generated from primary sources such as coal, natural gas, nuclear, or renewable sources like solar, wind, and hydro power. Primary sources are converted into electricity through various methods like burning, nuclear fission, or harnessing renewable energy.

The most common natural light sources are the sun, stars, and lightning. Other sources of natural light include bioluminescent organisms such as fireflies and certain deep-sea creatures.
Natural sources of electricity include sunlight (solar power), wind (wind power), flowing water (hydroelectric power), and geothermal heat (geothermal power). These sources provide renewable and sustainable ways to generate electricity without relying on fossil fuels.
Coal, oil, natural gas, hydro
There are many natural sources of nitrogen, two of which are mineralization of organic matter and animal waste.
Natural sources of light include the sun, stars, and lightning. Man-made sources of light include light bulbs, fluorescent lamps, and LED lights.
