Abstract
Due to increase in population, resource consumption and environmental degradation a major problems facing the earth planet is provision of an adequate supply of clean energy. All these three factors converging particularly in the matter of supply of sustainable energy. It is widely agreed throughout the world that our current energy practice will not provide for the entire world’s people in an adequate way and still leave our earth with a no livable environment. Hence a major task for the new century will be to develop sustainable and environmentally friendly sources of energy. Projection of future energy needs over this new century show an increase by a factor of at least two and one half perhaps by as much as a factor of five. All of the scenarios from reference three indicate continuing use of fossil sources nuclear and large hydro. However, the greatest increases come from ‘’new renewable’’ and all scenarios show extensive use of these sources by 2050. Indeed the projections indicate that the amount of energy derived from new renewable by 2050 will exceed that presently provided by oil and gas combined. This would imply major change in the world’s energy infrastructure.
