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.

Managing Energy Resources for the Future

In recent years, there have been many informative adverting campaigns on our television which sensitize viewers to the importance of preserving petroleum. We have seen in the course of the past three decades how the petroleum resources cause of wars being fought, economic shock, and general uncertainty. It is indeed devastating to think about our lives without these fossil fuels. Isn’t it scary to consider that when petroleum becomes rare our automobile industry, our airline industry and all those vehicles running on petrol could effectively come to a grinding halt? In that scenario, we can only picture a return of the cave-man days when walking will be the standard way to travel from one place to another.

There is no doubt that petroleum has brought innumerable benefits to civilization. Quality of life has improved with the use of gasoline in the internal combustion engines that power machines and vehicles. Oil and gas have been the power behind industry, and the source of heating fuel to provide comfort to homes. Heavy vehicles are powered by diesel. Energy companies produce everyday items from cosmetics to crayons and candles with the help of petroleum byproducts. The residues like tar, pitch and asphalt have traditionally been used for roads and to seal boats and to preserve wood.

The precarious situation of fast dwindling resources of petroleum has been a cause of concern for us all.  All around the world, the imbalance of demand versus supply has been one of the causes of spikes in oil prices. The oil price has escalated sharply three times, from $30 a barrel in 2008 to around $85 today. We all know that fossil fuels have been depleting rapidly. They also produce carbon dioxide as waste, which has been deposited in the atmosphere. These carbon residues have been identified as the major cause of global warming. These adverse effects have resulted in concerted efforts to find alternative and sustainable energy sources.

Use of sustainable energy is a rewarding option since this energy can benefit not just the present but the future also. While speaking of sustainable energy, solar energy and wind energy are the first to find their mention among energy conservationists. In the present context, we must look at solar energy or wind energy through the prism of environmental protection too since any renewable energy should not cause more global warming.

Oil and gas have fueled the world’s economies and in the coming years we should hopefully make new forays into green energy. Our energy companies have to build a stronger infrastructure that brings more green energy to the world.
