In today's rapidly developing world, vast amounts of energy resources are being utilized at an alarming rate, one which can certainly result in the extinction of our valuable natural resources. Moreover, majority of the energy resources utilized today are non-renewable natural resources like the petroleum products which account for nearly eighty percent of all the energy resources used. Thus, exploring alternative forms of energy so as to decrease our dependency on non-renewable forms of energy and consequently save the environment, has become more important than ever before.
Today, energy resources used especially, the petroleum products, and in some developing countries like Nepal, fuel wood, are major sources of Green House Gases (GHG), which is the prime cause of climate change. The threat of climate change to the whole of mankind is greater today than ever before. Rapid utilization of Earth's valuable resources has caused an imbalance in its delicate natural processes, effect accelerating the rate of climate change, which is in fact a natural phenomenon. Thus, although climate change is a natural process, the alarming rate at which it is being noticed today has posed a serious thereat to the existence of mankind as we know it. And, almost all the credit of this danger lurking in our life goes to the over utilization of petroleum products because of their harmful byproducts. Therefore, exploring and utilizing green and alternative sources of energy has not only become important to save our Earth's valuable resources but the Earth itself and along with it all the living creatures that call it "home".
Thus, it is seen that exploring alternative energy resources is very important. It is not only important to save energy resources for future generations and to provide them the technology to utilize better, unlimited sources of energy and save the Earth. It has also been seen as important step to curb the world's poverty by creating millions of so-called "Green Jobs". It is a fact that millions of workforce will be required to create and maintain infrastructures to tap solar energy, wind energy, hydroelectricity and other alternative energy resources. Also, many people will be required to save forests and use it sustainably.
It is being debated that exploring and utilizing alternative sources of energy will need billions of investment and curbing the current rate of use of non-renewable resources will result in economic meltdown. This is partly true. However, although a lot of investment is needed for exploring and utilizing alternative energy sources, it can certainly give very huge benefits. Reduction of dependency on petroleum products and a security for future when non-renewable resources are used up are some of the benefits. There are also arguments that such alternative sources of energy like solar energy are very expensive because of the initial high cost of setting the equipments. But, if we develop cheaper technology to tap such alternative energy through collective efforts and investment, such resources will be very much cheaper than the petroleum products that we so heavily rely on today. Also, hydroelectricity and similar alternative sources like bio-gas are only expensive to develop but the cost of unit energy will be very cheap.
Similarly, what people raising voice against the exploration of alternative sources of energy, seem to be unaware of is that petroleum products will eventually be used up. They must be questioned, "What then?" "What will our future generations survive on?" "What will be the condition of future economy?" Thus, it is clear that exploration of alternative forms of energy is very important, in fact, unavoidable. Doing it is the only way possible to save our future generations. No doubt, this argument is debated for and not against by people not driven by lust for power and riches.
