In these times of worldwide skyrocketing energy costs, experts are turning to perhaps the only energy source that is still immune to price fluctuations: the Sun. Economic necessity appears to be largely responsible for the rapidly growing acceptance of solar heat as an alternative source. Electricity has been a clean and versatile form of energy that continues to grow in importance for lighting, heating and cooking, and for powering our increasingly automated and computerized society. The demand for electricity is expected to grow more in future than the average trend in the past. A mix of energy sources is required as hedge against shortages in any one area, and the electricity supply companies are taking a second look at renewable generating technologies, particularly those based in the sun. Every 15 minutes, the sun delivers to earth radiant energy to meet all mankind's power needs for a full year. But harnessing this energy is complicated by two properties of sunlight: its diffuseness and its variability with time of day, season and weather conditions. These factors pose formidable technical challenges for the efficient conversion of solar radiation into bulk, utility grade electric power. Nevertheless, solar technologies are attractive to utilities because they are environment-friendly and offer a low regulatory risk, limited capital risk, and less lead time.

The political system always dominates the entire social scene; and hence those who wield political power are generally able to control all the different social sub-systems and manipulate them to their own advantage. The social groups in power therefore have always manipulated the education systems,
especially when these happen to depend upon the state for their very existence to strengthen and perpetuate their own privileged position. But herein lies a contradiction. For the very realization of their selfish ends, the social groups in power are compelled to extend the benefits of these educational
systems to the under-privileged groups also. The inevitable task is generally performed with three precautions abundantly taken care of: One, the privileged groups continue to be the principal beneficiaries of the educational system, dominate the higher stages of education or the hard core of prestigious and quality institutions or the most useful of courses, so as to safeguard their dominant position of leadership in all walks of life. Second, the system is so operated that under-privileged groups can utilize it only marginally in real terms and the bulk of them become either dropouts or pushouts and get reconciled to their to their own interior status in society. Third, the few from the weaker section that survive and succeed in spite of all he handicaps are generally co-opted within the system to prevent dissatisfaction.
