Utilization of electrical energy is inevitable in today’s world. 70% of the energy generated is obtained by combustion of fossil fuel (coal). Over exploitation of these resources has led to serious environmental pollution and depletion. Thus it is mandatory to shift our attention towards renewable sources for sustainable utilization of these resources. As a contribution to the nation and the environment as a whole, the institution is utilizing renewable sources of energy and energy efficient systems and devices. Solar thermal, Solar electrical – Grid connected, Bio –gas, automated systems for energy conservation and energy efficient devices such as LED bulbs to meet the lighting loads in the night time.

S.No	Power Details	Usage of Power
1	Annual power requirements met by the renewable (Solar) energy source KWH	1KW/4unit x 50KW x30 days x 12 months =4 x 50 x 30 x 12 =72,000Kwh /Year (Unit)
2	Total power requirements in Kwh	EB 110 kw (40kw) X 3 Service x 8hrs x 25 Days x 12 Months = EB 2,88,000 Units + Solar 72,000 Units Total power Usage Per Year in Kwh (Unit)= 3,60,000 (Unit)
