Our Need for Renewable Sources of Energy

Energy, environment and associated global warming concerns are the focus of raging debates as the global climate system impacts the political climate. The impending energy crisis and the soaring oil prices have their roots in the fast depleting non-renewable source of energy: petroleum. Petroleum takes the spotlight as the world’s primary energy resource as the petroleum industry produces indispensable gasoline and other fuel derivatives.

Everyone is well aware that these fuels have become part and parcel of our daily lives; it is imperative to understand what a critical role they play in the functioning of the world. Take the transportation industry for instance: the waterways, roadways, airways and rail transport all depend upon petroleum products (gasoline, diesel etc) for movement. And gas is still the chief medium of cooking for household kitchens.

A rise in the global population and a consequent increase in demand for oil and gas have meant that a heavy premium is levied on the usage of petroleum products. Worse, the increased usage of gasoline has resulted in the release of poisonous chemicals into the earth’s atmosphere, not sparing the water bodies which get heavily polluted by petroleum based industries.

So, the search is on for safe, renewable sources of sustainable energy that won’t pose any hazards in the long run. Efforts are also on to find effective means for creating green energy, meaning energy that is environmentally less damaging. For example, wind energy, solar energy, hydro energy can be tapped and channelled from different natural sources either to generate power (through solar cells, wind turbines, etc.) for myriad applications. These sources are inexhaustible, unlike petroleum and its derivatives, which are getting used up faster with each passing day.

As an alternative to gasoline, other pollution-free fuels such as hydrogen fuels, CNG (compressed natural gas), and biofuels are efficient, environment friendly and finding good acceptance the world over. Though the production of these fuels is yet to be undertaken on a scale large enough to supplant fossil fuels, the vehicles using them and leading the ‘save fuel, save energy’ campaigns are already showing the way for an ‘energizing future’.

The economy of the US is sustained by major oil producing industries and energy companies have begin to faced the backlash of fuel exploitation, a body blow resulting in recession. But revival measures are in full-swing in the US and other countries; by exploring the usage of alternate energy resources, the world can ensure sustainable growth and an economically stable future.
