Everything in
the UNIVERSE is made from energy. It can take many forms like
heat, light, electricity, sound, strain, gravitational, chemical
etc. Energy can change from one form to another. It can never be
created nor destroyed. The total amount of energy in the
universe always remains the same.

Coal,
oil, and natural gas are the primary commercial sources of
energy in India. In addition, traditional energy sources like
fuel wood, agricultural waste, and animal residue constitute a
large part (nearly 40%) of the total energy consumption. In 1998/99, commercial energy consumption in India was estimated at
195.11 million tones of oil equivalent, indicating a 75% growth
over a decade. However, India’s per capita consumption of
commercial energy continues to be much lower than the global
average of about 1684 kilograms of oil equivalent and is
5%–10% that of developed countries like Japan, France, and USA
(World Development Report 1999/2000, World Bank).

India
recognized the importance of increasing use of renewable energy
sources for achieving a sustainable energy base in the
early 1970's. During the past quarter of a century, a
significant thrust has been given to the development, trial and
induction of a variety of renewable energy technologies for use
in different sectors. Renewable energy is seen as an effective
option for ensuring access to modern energy services in our vast
country. In addition, it also provides a degree of national
energy security. In recent years, the rationale has been further
buttressed by the environmental imperative. Local and regional
environmental problems associated with the generation of
conventional energy have provided a strong argument for
enhancing the role of renewable energy within the broad energy
development plans of the country. More recently, the Kyoto
Protocol, agreed at the Conference of Parties to the Framework
Convention to Climate Change, in December 1997, adds a global
perspective to the environmental
imperative.
