INTRODUCTIONINTRODUCTIONEnergy conservationEnergy conservation

Energy conservation refers to efforts made to reduce energy Energy conservation refers to efforts made to reduce energy consumption. Energy conservation can be achieved through consumption. Energy conservation can be achieved through increased efficient energy use, in conjunction with decreased increased efficient energy use, in conjunction with decreased energy consumption and/or reduced consumption from energy consumption and/or reduced consumption from conventional energy sources. conventional energy sources.

Need of energy Conservation:-Need of energy Conservation:- Energy conservation reduces the energy consumption and Energy conservation reduces the energy consumption and

energy demand.energy demand. Energy conservation is an important element of energy policy Energy conservation is an important element of energy policy This reduces the rise in energy costs, and can reduce the need This reduces the rise in energy costs, and can reduce the need

know first which areas in your establishment unnecessarily know first which areas in your establishment unnecessarily consume too much energy, e.g. which is the, sot cost effective to consume too much energy, e.g. which is the, sot cost effective to improve.improve.

An energy audit identifies where energy is being consumed and An energy audit identifies where energy is being consumed and assesses energy saving opportunity- so you get to save money assesses energy saving opportunity- so you get to save money where it counts the most.where it counts the most.
