Sustainable Energy Sources


Energy is life. Life on this planet depends upon a fixed amount of energy. The modern industrialized energy sources such as coal and petroleum were originally utilized for their seeming promiscuity and high energies yielded per unit volume. The world has now become painfully aware of how finite petroleum reserves are, not to mention the political complications associated with being dependent upon foreign countries for an energy supply. To add insult to injury, the limitedness of petroleum resources is not the most pressing problem, their polluting byproducts are. The enormous amounts of byproduct waste that finds its way into our environment is having effects which even the most renowned of experts cannot

The straw that breaks the camel’s back could fall with a whisper, 100 years before the full ramifications of that ‘straw’ are known.

In the more developed countries (MDC) of the world, the average electricity capacity is roughly 1 KW per person and growing . At current rates of growth the population of the world is projected to reach 10,000 million during the next century. If all today's developing countries reach a standard of living comparable to the MDC's of today the global demand for electricity is likely to require some10,000 million KW of capacity, about 10 times its present level. At our present technological advance, the world is not capable of accomplishing this energy output level. Coal, oil, gas, nuclear fuel are all limited fossil resources, and in addition nuclear technologies have great dangers associated with them. Nuclear energy is a viable energy source, but the potential for accident and our current lack of knowledge as to how to handle the poisonous byproducts outweigh its energy benefits.

As we search for the energy sources that are to sustainable power the world, it is important that we concentrate our research upon sources of energy that are renewable , perpetual and clean. Climatic, economic and supply factors must be taken into account but short term considerations of price, supply and demand cannot be allowed to take sole precedence in determining what the fuels and energy sources the future…
