Green Energy

Green energy includes natural energetic processes that can be harnessed with little pollution. Anaerobic digestion, geothermal power, wind power, small-scale hydropower, solar energy, biomass power, tidal power, wave power, and some forms of nuclear power (ones which are able to “burn” nuclear waste through a process known as nuclear transmutation, e.g. an Integral Fast Reactor), and therefore belong in the “Green Energy” category). Some definitions may also include power derived from the incineration of waste.
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. Some have argued that although green energy is a commendable effort in solving the world’s increasing energy consumption, it must be accompanied by a cultural change, namely one that encourages the decrease of the world’s appetite for energy, if it is to have the impact the world so eagerly anticipates.
