What Is Clean Energy?

Clean energy is energy that is produced through means that do not pollute the atmosphere. It can also refer to renewable energy sources that do not create environmental debt: using up resources that cannot be replaced or severely damaging the environment so that future generations must solve problems created today.
Currently, most known energy production methods have some type of environmental impact, so clean energy describes the energy production methods with the least amount of impact on the environment.
The primary sources of clean energy are- solar energy, hydro energy, geothermal, tidal and wind energy.
