Biomass is a renewable energy resource derived from the
carbonaceous waste of various human and natural activities and
is free from net Co2 emissions. It is abundantly available on
earth as agricultural residue. Approximately 87% of GHG
emissions are on account of power generation. Biomass has the
potential to generate reliable, secure and clean power. The
national power capacity from surplus Biomass materials is
assessed to exceed 16,000 MW.

It is estimated that the Sun sends each year over a billion
terawatt hours of energy to the earth, which is equal to
60,000 times the world’s electricity needs. For academic
perspective, less than 3% of the surface area of SAHARA would
be sufficient to meet the world’s Energy demand with Solar
plants. Solar plants convert heat energy to
electricity by different means. Continuous R&D is underway to
optimize the cost of power generation
from sun energy, which is relatively high
today.

Driven by policy
initiatives and incentives, the development of the small hydro
power (SHP) sector is gaining rapid grounds in India. By
definition, a hydro project of less than 25MW is generally
considered under the category of SHP. The small hydro
projects, score over big projects on several counts. They can
supply power to remote and hilly areas without transmission
network, involve limited investments, undergo fast financial
closures and could bring quick returns.
