Green Energy is energy that can extracted, generated, and consumed without any significant negative impact to the environment. The planet has a natural ability to recover which means pollution that does not go beyond that ability can still be termed green.
Green energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.Green energy replaces conventional fuels in four distinct areas: electricity generation, air and water heating, motor fuels, and rural (off-grid) energy services.
Green energy includes natural energetic processes that can harnessed with little pollution. Green power is electricity generated from renewable energy sources. Some have argued that although green energy is a commendable effort in solving the world's increasing energy consumption, it must accompanied by a cultural change that encourages the decrease of the world's appetite for energy.
