Energy is an indispensable commodity in every walk of human life and it is also most vital resource for development of our country. The high demand of energy, acute shortage of electricity and increasing cost of oil is matter of great concern & hence optimum utilization of energy resources and thereby conservation of energy is moral duty of all of us.
In view of the grim energy scenario in the country & degradation of environment, the Government of India has enacted the Energy Conservation Act 2001 with the objective to emphasis upon energy efficacy drive in the country. The Bureau of Energy Efficiency
( BEE ) has been established and the Standard & Labeling Programme launched to ensure that only BEE has formulated the procedure to fix labels at set standards for minimum energy consumption by the manufacturers of appliances.
When the energy saved also means the energy generated, it is wiser and highly economical to save it by applying the energy saving measures as suggested below.
ILLUMINATION :
Ø Switch off tube lights, fans, etc. when not required.
Ø Prefer task lighting instead of uniform one all over.
Ø Follow recommended illumination levels.
Ø Use energy efficient lamps & luminaries.
Ø Keep clean all lighting equipment and reflectors.
Ø Optimize use of natural lighting.
Ø Prefer electronic ballast instead of conventional chokes.
Ø Prefer compact fluorescent lamps.
Ø Use current / voltage reducer.
HOUSING COMPLEX :
Ø Use photo electric control or timers to on / off the street lights.
Ø Provide alternate light fittings in common areas and staircase landings.
Ø Wherever, more than one passenger lifts are provided, use only single lift during non-peak hours.
Ø Use of lifts may be restricted for going up beyond 3 floors / fights.
Ø Switch off T.V., music system, battery / cell phone chargers etc. from main plug.
Ø Use power factor correction capacitors with water pumps and lift to reduce current taken and losses.
Ø Use water level controllers for overhead tanks to automatically switch off the pumps.
Ø Undertake energy saving measures, conduct periodic energy audits.
Ø Explore use of renewable energy sources such as solar and wind energies.
HOUSE HOLD ELECTRICAL APPLIANCES:
REFRIGERATORS :
Ø Refrigerator accounts for about 25% of your electricity bill.
Ø Regularly clean condenser coils for dust deposit to attain better heat transfer.
Ø For regular use, set thermostat of the refrigerator on medium range and avoid frequent opening of fridge.
Ø Ensure tightness and proper fitting of door gaskets.
Ø Make sure refrigerator is not placed against walls exposed to direct sunlight.
Ø Keep the refrigerator and freezer at right temperature; if they are 2 to 3 degree colder than necessary the electric consumption may go up approx. 25%.
Ø Allow hot food to cool off before keeping it in the refrigerator.
Ø Defrost refrigerator regularly.
WASHING MACHINE :
Ø Washing machine can account for as much as 20% of the electricity used.
Ø Each wash cycle uses up to 60 to 90 litres of water.
Ø Use washing machine on full load and plan washing periodicity to save on water too.
Ø Add only required amount of detergent.
Ø Adding to much detergent actually hampers effective washing action and may require more energy in the form of extra rinses.
AIR CONDITIONERS :
Ø Check air gaps around window for proper sealing.
Ø Place air conditioners in the shade.
Ø An air conditioner exposed to direct sunlight uses 5% more energy than a shaded one.
Ø Minimize the amount of direct heat entering your home by pulling shades and curtains on hot days.
Ø Set thermostat to as high as comfort permits, may be a few degrees higher.
Ø Check and clean or replace air filters every month.
IN THE KITCHEN :
Ø Keep the entire material ready before lighting the stove.
Ø Let cold material attain room temperature before cooking.
Ø Soak the grains and cereals before you cook them.
Ø Avoid use of excessive water in cooking.
Ø Use utensils having broad base.
Ø Use lid on cooking utensils.
Ø Prefer small burner and light flame.
Ø Ensure stable, bright and blue flame.
Ø Reduce flame when boiling starts.
Ø Use only ISI mark stoves and kerosene wicks.
Ø Use pressure cooker.
Ø Cook different types of food simultaneously by using separators.
Ø Avoid often reheating of food.
Ø Store food in insulated containers.
FUEL OIL CONSERVATION FOR VEHICLES :
Ø Get the vehicle regularly serviced and engine tuned.
Ø Maintain correct tyre pressure.
Ø Clean air-filter regularly.
Ø Drive in correct gears and at optimum & uniform speed.
Ø Keep your food off the clutch and use it only while changing gears.
Ø Avoid idle running of engine.
Ø Make the vehicle lighter, reduce unnecessary load.
Ø Plan your trips and route and avoid rush-hour traffic.
Ø Prefer cycle than fuel-operated vehicles.
GENERAL :
Ø Use high efficiency and optimum size equipment.
Ø Optimize use of plant utilities such as steam, cooling water, compressed air etc.
Ø Monitor and control all plant parameters strictly.
Ø Install monitoring instruments like flow meter, pressure & temperature gauges, ammeter etc. wherever necessary.
Ø Carry out periodic preventive maintenance, remove the scaling sedimentation regularly.
Ø Stop all leakages. Avoid unnecessary long distribution pipelines.
PUMPS & COMPRESSORS :
Ø Avoid throttling and if possible, trim the impellers.
Ø Use more small pumps / compressors instead of one large one.
Ø Use direct coupled and high efficiency flat belt driven system.
COOLING TOWERS AND REFRIGERATION SYSTEM :
Ø Use thermostatic controller for cooling tower fan.
Ø Use high efficiency drift eliminator and FRP blades.
Ø Use PVC fills instead of concrete or lumber.
Ø Optimize need of refrigeration and refrigeration temperature.
Ø Don’t use weak or broken insulation.
Ø Store chilled water / ice during off –peak hours and use it during peak hours.
MOTIVE LOAD :
Ø Avoid idle running of motors.
Ø Use star delta changeover.
Ø Use soft starter for high torque.
CONTROL OF MAXIMUM DEMAND :
Ø Improve load factor to maximum.
Ø Improve power factor by installing capacitor bank and automatic power factor correction system.
Ø Install automatic demand controller system.
Ø Select optimum sanctioned demand.
Ø Minimize peak demand.
