1. TIPS FOR ENERGY CONSERVATION

2. INCANDESCENT VS. CFL
Incandescent bulbs have a burning filament that produces heat in addition to light. This heat has
a negative effect on the life of bulb and costs money in your electricity bill without creating extra
lumens (measure of light).
CFL bulbs produce almost no heat and save you energy by only giving off light instead of
wasting energy on extra heat that shortens the life of the bulb.
75% energy savings – Compact Fluorescents will save over 75% of energy used per lamp. You
can change every 60 watt bulb in your house with a 13 watt Compact Fluorescent. Less wattage =
Less Energy.
Lasts 10 times longer – Compact Fluorescent light bulbs last 10 X’s longer than traditional
incandescent bulbs. You know that hard to reach light in your entry way? Well, you will only have
to change it 1/10 of the time you do now!

3. • Less Expensive - Although the price per bulb is higher you get what you pay for by saving money in the
long run because CFL's use 1/4 the electricity and last up to 10 times as long as incandescent. A single 18
watt CFL used in place of a 75 watt incandescent will save about 570 kWh over its lifetime. At 8 cents per
kWh, that equates to approx rs.2000.
• Reduces Air and Water Pollution: Replacing a single incandescent bulb with a CFL will keep a
half-ton of CO2 out of the atmosphere over the life of the bulb. If everyone in the U.S. used
energy-efficient lighting, we could retire 90 average size power plants. Saving electricity reduces
CO2 emissions, sulfur oxide and high-level nuclear waste.
• Versatile: CFL's can be applied nearly anywhere that incandescent lights are used. Energy-
efficient CFL's can be used in recessed fixtures, table lamps, ceiling fixtures and porch lights. 3-
way CFL's are also now available for lamps with 3-way settings.
• High-Quality Light: Newer CFL's give a warm, inviting light instead of the "cool white" light
of older fluorescents. They use rare earth phosphors for excellent color and warmth. New
electronically ballasted CFL's don't flicker or hum.

4. LED VS. CFL
Lifespan, brightness and efficiency are important factors in selecting lights for any purpose. Standard
incandescent lights operate when an electric current is sent through a filament, which produces heat, and the
heat produces light. Light-emitting diodes (LED) produce light through a process called electroluminescence,
in which a substance acted upon by an electric field produces a cold light. Each type of bulb offers different
brightness, wattage and energy efficiency.
LED bulbs require only 6 watts to produce the same amount of light as 14 -watt fluorescent bulb . LED bulbs'
lower wattage combined with drastically longer lifespan results in significant cost and energy savings over
fluorescent bulbs. The comparison data published by Earth Easy shows that a single LED bulb will use 300
kilowatt hours of electricity over its 50,000-hour lifespan. The equivalent fluorescent bulbs will use 700
kilowatt hours of electricity during that 50,000 hours.
Recycling and Disposal
With a functional lifespan of more than 25 years under normal residential conditions, chances are you may
only replace your LED bulbs once or twice in your lifetime. Most LED manufacturers offer a two -year
warranty, as most defective LED bulbs will fail within that time. Disposing of LEDs is much safer for the
environment than fluorescent bulbs, which contain mercury. According to Earth911, many major retailers and
online groups will recycle LEDs for you. If you do not have a recycling center nearby, call your local waste
management company to find out how to dispose of LEDs properly.

5. AIR CONDITION OPTIMIZATION
• The most obvious cost-cutting can happen by using ceiling fans instead of air conditioners
whenever possible. The differential in operating cost is approximately 30 paise per hour for
fans as opposed to Rs 10 for air conditioning. Replacing the metal blades of a fan with fiber
blades can save 20% energy overall.
• However, if air conditioning is all that you have, each degree set above 22 Celsius will use 3-
5% less energy. The recommended temperature to set the thermostat at is 25 Celsius, which
is both comfortable and cost efficient.
• For those who are planning on installing air conditioning in new offices, it is advisable not to
go for centralized air conditioning., “Because it is a single unit, it has to be run for the entire
office, irrespective of selective places where it is required after normal work hours. Split air
conditioning is recommended, which allows you to cool specific pockets where the cooling is
required.” Besides this, cleaning the filter of air conditioners enables quick cooling while
being energy efficient.

6. COMPUTERS, LAPTOPS ….
• Near about 50% of power is hogged by the monitor alone. Setting up a
company wide policy to switch off the monitors of idling workstations can
help you curb a lot of wastage.
• Approximately 40% of energy costs can be cut down if one were to put
computers and peripherals like printers and copiers on sleep mode when
not in use.
• Electronic devices, such as battery chargers for laptops, phones, cameras,
etc., keep drawing power if plugged in. Simply encourage unplugging these
when not in use.
If you turn off your monitor for a minute, a bulb can be lit
in some remote part of India for about 2 minutes.

7. • Desktop uses 125 watt (active mode) running for
6 hrs a day will use 0.76 Kwh and for 2160 hrs
yearly will use 270 Kwh of electricity.
• Laptop in active mode uses only 30 watts.

8. CARPOOLING
• Carpooling with one person would save 17164/year,2 person
11440/yearly.`
• Turn off the car if you will be idling for 10sec.On an average
0.098 litres of fuel every day get wasted for idling.
• 10..35770 litres of petrol would be saved by 1000 cars for 365
days.

9. PLASMA VS. LCD
• An average LCD TV uses 111 watt running for 6 hours a day will use 0.66 Kwh and
for 2160 hrs yearly will use 239.76Kwh.
• 1000 people using 239.76 Kwh will use 239760 watt of electricity yearly.
• Plasma takes 0.30 watt per square inch which is 0.16 watt per square inch for a
LCD.
