Green Sources of Green Energy
Green energy is popular now in the world. We also call it as renewable energy. Green energy by some definitions includes natural energetic processes that can be harnessed with little pollution.
Green energy includes anaerobic digestion, geothermal power, wind power, small-scale hydropower, solar energy, biomass power, tidal power, and wave power fall. Some definitions for green energy may also include power derived from the incineration of waste.
Below some images are presented for green energy:

Tidal Energy:
Also some organizations have specifically classified nuclear power as green energy, but environmental organizations indicate the problems with nuclear waste and claim that this energy is neither efficient nor effective in cutting CO2 emissions, excluding it from clean energy.
But no power source is entirely impact-free. All energy sources require energy and give rise to some degree of pollution from manufacture of the technology.
