Green power for a sustainable future

Renewable energies are considered as an essential element of any strategy for sustainable energy development. The poor in the developing world without access to modern energies are regarded as a major market for renewable energies. Renewable energies are expected to play a major role in the global future energy provision. There has been interest in electricity from renewable sources named green electricity or green pool as a special market. The term green energy is also used for green energy produced from cogeneration, energy from municipal waste, natural gas, and even conventional energy sources. Green power refers to electricity supplied from more readily renewable energy sources than traditional electrical power sources. The environmental advantages of the production and use of green electricity seem to be clear. Renewable energy sources are the third largest contributor to global electricity generation. The aim of the present paper is to investigate the contribution of renewable sources to global electricity demand and future prospects of green electricity generation.
