What is “green energy” and why does it matter?
Against the scenario described above, terms like green energy and sustainability hold the key to a better tomorrow. Green energy refers to natural sources of energy that are environmentally friendly-energy that does not produce pollution in its wake and is naturally replenished. The common sources of renewable energy would include power from anaerobic digestion, biomass power, fuel-cell power, geothermal power, small-scale hydropower, solar power, tidal power, wave power and wind power. Some people add nuclear power in the category of green energy-this, however, can be debated because of issues related to nuclear safety and waste. Green energy is increasingly gaining value in today’s more environmentally-conscious world, in which people are aware of the importance of sustainable, renewable energy sources and the impact human activities have on the environment. Green energy is being harnessed and used for electricity, heating and cogeneration.
