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.
