Green Energy is a term describing what is thought to be environmentally friendly sources of power and energy. Typically, this refers to renewable and non-polluting energy sources.
Green energy includes natural energetic processes which can be harnessed with little pollution. Anaerobic digestion, geothermal power, wind power, small-scale hydropower, solar power, biomass power, tidal power and wave power fall under such a category.
Some versions may also include power derived from the incineration of waste........
Medium or large-scale hydroelectric power or sources of air pollution such as burning biomatter or petroleum, are often excluded from the label 'green energy'.
In several countries, current electricity retailing arrangements make it possible for consumers to buy green electricity, either by purchasing their electricity from a generating company that uses only renewable technologies, or by buying from a general supplier who undertakes to buy at least as much power from renewable sources as their "green" customers purchase. Generally green electricity commands a price premium compared with standard supplies.
Obviously this option is only available where common carrier arrangements have been put in place to allow competitive supply of power.
Renewable energy certificates (Green certificates, or green tags) are currently the most convenient way for consumers and businesses to support "green power". Over 35 million homes in Europe, and 1 million in the United States, are purchasing such certificates.
No power source is entirely impact-free. All energy sources require energy and gives rise to some degree of pollution from manufacture of the technology.
