CONSERVATION OF ENERGY
Why should we conserve energy?
We use energy faster than it can be produced.
Coal, oil and natural gas - the most utilized sources take thousands of years for formation.
Energy resources are limited.
India has approximately 1% of world’s energy resources but it has 16% of world population.
Most of the energy sources we use cannot be reused and renewed
Non renewable energy sources constitute 80% of the fuel use.
It is said that our energy resources may last only for another 40 years or so.
We save the country a lot of money when we save energy.
About 75 per cent of our crude oil needs are met from imports which would cost about Rs.1, 50,000 crore a year
We save our money when we save energy.
Imagine your savings if your LPG cylinder comes for an extra week or there is a cut in your electricity bills
We save our energy when we save energy
When we use fuel wood efficiently, our fuel wood requirements are lower and so is our drudgery for its collection
Energy saved is energy generated.
When we save one unit of energy, it is equivalent to 2 units of energy produced
Save energy to reduce pollution
Energy production and use account to large proportion of air pollution and more than 83 percent of greenhouse gas emissions
It is our duty to conserve today for tomorrow’s use.
An old Indian saying indicates “The earth, water and the air are not a gift to us from our parents but a loan from our children”.

90% of the total electricity used by a standard incandescent light bulb is wasted as heat. |
TIPS ON ENERGY CONSERVATION
Lighting system
- Turn off lights when not required.
- As far as possible use task light like a reading lamp
- Dust your tube lights and lamps regularly
- Compact Fluorescent Lamps (CFLs) are more efficient than ordinary bulbs and saves about 70% electricity for the same amount lighting levels.
- Use one large wattage instead of two small ones.

Air Conditioners
- Use table or ceiling fans to beat the heat and save on costs
- Provide shade to your home windows and walls
- Set the thermostat of room air conditioner at 25°C (77°F) to provide the most comfort at the least cost.
- Consider using ceiling or portable fans to circulate and cool the air.
- Keep the doors and windows of the air -conditioned room closed as far as possible.
- Clean the air filters on a regular basis.
- Buy only energy efficient air conditioners.
- Keep outside air conditioning units free from leaves that may clog the vent.
Laundry
- Use clothesline instead of drier when possible
- Always run the machine when fully loaded
- Use cold water too wash clothes whenever possible
- Clean the dryer filter after every load
- Use minimum time necessary to dry the clothes
Computers
- Turn off the computer when not in use
- If your computer must be left on ,turn off the monitor
Refrigerator
- Must keep the refrigerator away from direct sunlight, radiators and appliances like oven
- Try to keep it full but make sure that to allow adequate air circulation inside
- Reduce the time the door remains open
- Allow the warm food to cool and seal them well before refrigerating them
- Make sure that the rubber door seals are clean and tight.
- Defrost freezer compartment regularly for a manual defrost refrigerator
Less Energy, More Light – CFL
Today at least 80 per cent of electricity is wasted – because of the kinds of lamps, bulbs and other implements we use that consume more electricity.
CFL (Compact Fluorescent
Lights) reduces electricity costs. A CFL bulb gives five times more light
than conventional electric bulbs. CFL burning hours are more than 8 times
the normal ones. Fluorescent tube lights, compact fluorescent lights,
consume less electricity and do not produce too much heat. Instead of
using 60-Watt bulbs, if you would use 15-Watt CFL bulbs; you can save at
least 45-Watt electricity consumption per hour. Per month you can save up
to 11 units of consumption. You can reduce costs. CFL bulbs last for at
least 5 to 8 months.
Why CFLs?
Compact
fluorescent bulbs (CFLs) use about two-thirds less energy than
incandescent bulbs with no reduction in quality of light. Compact
fluorescent bulbs will give an incandescent bulb's warm, soft light, while
using up to 75 percent less electricity
CFLs are slightly costlier but are worth investing, as they are smaller, cheaper, brighter, and offer improved color quality. Typically, a 23-watt compact fluorescent bulb can replace a 90 or 100-watt incandescent bulb
Use compact fluorescent bulbs in fixtures that are on for more than four hours a day. By replacing only two 75-Watt light bulbs that are on four hours a day by two 15-watt energy-saving lamps, you can save almost 18 Kilo Watt hours per year.
