What is green energy?

Green energy is energy that is produced in a manner that has less of a negative impact to the environment than energy sources like fossil fuels, which are often produced with harmful side effects. “Greener” types of energy that often come to mind are solar, wind, geothermal and hydro energy. There are several more, even including nuclear energy, that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil.

In my point of view "Green energy" is energy that is output in a manner that has sparing of a negative influence to the atmosphere than energy sources like fossil lignite, which are often produced with deleterious side effects. “Greener” types of energy that mostly come to good sense are solar, wind, geothermal and hydro energy.

Green energy is any type of energy not drawn from fossil fuel and that doesn't pollute the atmosphere..wind..wave..solar..are all green energy..as are hydrogen fuel cells..the by product of which is water

Most of these answers are referring to "political" green energy. I however am referring to the scientific explanation of green energy. Green energy is a rare occurrence when lightning strikes the leaf the of a plant and supercharges the growth of chlorophyll (the chemical that makes leaves green) and thus when the lightning bounces off the plant the energy is reflected green and then runs through multicolored air particles to create a double rainbow striking the ground and making a rare chemical reaction resulting in small formations of gold depending on the amount of iron in the ground. If it, however, trikes a metal pot it will in turn make a pot of gold and the green light will stunt the growth of any nearby children and the green energy will change the color of his clothing effectively making what is referred to as a leprechaun. Therefore green energy is the early stage of the production of a pot of gold at the end of a double rainbow.

Green force is vigor that is handled in a way that has less of a negative effect to nature than force origins enjoy fossil powers, which are frequently prepared with terrible symptoms. “Greener” sorts of life that regularly come to psyche are sun based, wind, geothermal and hydro vigor. There are some more, yet incorporating atomic force, that is off and on again recognized a green force cause in light of its easier waste yield relative to power causes for example coal or oil. The object of green life is usually to make capacity with as meager contamination would be prudent transformed as a by-item. Each manifestation of power accumulation will consequence in some contamination, but the aforementioned that are green are known to create less than the aforementioned that are not.

As per wikipedia, green energy is defined as "Sustainable energy is the provision of energy such that it meets the needs of the present without compromising the ability of future". For example, solar power, windmills, and hydro power.

Energies which are produced by natural agents are known as green energy.

Eco friendly. Like wind mills or dams
