With emerging renewable energy alternatives today, it is highly important that they be given enough attention even early on their developmental stages. Such technologies might not be ready for commercial uses yet but their potential should be amply tested and funded. Society's modern lifestyle is in serious need of energy that can be generated and consumed and yet, not compromise the future state for generations to come; to have no anxiety that it would cause damage to the environment.
Green energy could come from such sources available in our environment that are naturally replenished and efficient like tides, wind, sunlight and geothermal heat. It is very different from low-carbon energy as the former does not add to the amount of carbon dioxide in the atmosphere at all, thus, coming with minimal environmental harm and greenhouse gas.
Concerns in climate change and increasing oil prices are some of the contributing factors in drawing the spotlight to renewable energy and its potential for commercialization. Green energy can effectively replace our conventional fuel of today in all its main uses, which are in heating, vehicle fuel and electricity generation sectors. In fact, 19% of the electricity generated around the world today comes from renewable sources. Furthermore, since the emergence of biofuels in the United States 6 years ago, consumption of conventional oil has decreased significantly.
For a green energy resource or technology to be sustainable, it has to give the maximum environmental advantage while still serving its purpose.
