Tips on Energy Savings |
| Tips for Energy Conservation for Industries (pdf format) |
| Lighting System |
01. |
One of the best
energy-saving devices is the light switch. Turn
off lights when not required. |
02. |
Many automatic
devices can help in saving energy used in lighting.
Consider employing
infrared sensors, motion sensors, automatic timers,
dimmers and solar cells wherever applicable, to
switch on/off lighting circuits. |
03. |
As
for as possible use task lighting, which focuses
light where it's needed. A reading lamp, for example,
lights only reading material rather than the whole
room. |
04. |
Dirty
tube lights and bulbs reflect less light and
can absorb 50 percent of the light; dust your
tube
lights and lamps regularly. |
05. |
Fluorescent
tube lights and CFLs convert electricity to visible
light up to 5 times more efficiently than ordinary
bulbs and thus save about 70% of electricity for
the same lighting levels. |
06. |
Ninety
percent of the energy consumed by an ordinary bulb
(incandescent lamp) is given off as heat rather
than visible light. |
08. |
Replace
your electricity-guzzling ordinary bulbs (incandescent
lamps) with more efficient types. Compact fluorescent
lamps (CFLs) use up to 75 percent less electricity
than incandescent lamps. |
09. |
A
15-watt compact fluorescent bulb produces the
same amount of light as a 60-watt incandescent
bulb. |
| Room Air Conditioners |
01. |
Use
ceiling or table fan as first line of defence
against summer heat. Ceiling fans, for instance,
cost about 30 paise an hour to operate - much
less than air conditioners (Rs.10.00 per hour). |
02. |
You
can reduce air-conditioning energy use by as much
as 40 percent by shading your home's windows and
walls. Plant trees and shrubs to keep the day's
hottest sun off your house. |
03. |
One
will use 3 to 5 percent less energy for each
degree air conditioner is set above22°C (71.5°F),
so set the thermostat of room air conditioner
at 25°C (77°F) to provide the most comfort
at the least cost. |
04. |
Using
ceiling or room fans allows you to set the thermostat
higher because the air movement will cool the room. |
05. |
A
good air conditioner will cool and dehumidify a
room in about 30 minutes, so use a timer and leave
the unit off for some time. |
06. |
Keep
doors to air-conditioned rooms closed as often
as possible. |
07. |
Clean
the air-conditioner filter every month. A dirty
air filter reduces airflow and may damage the
unit. Clean filters enable the unit to cool down
quickly
and use less energy. |
08. |
If
room air conditioner is older and needs repair,
it's likely to be very inefficient. It may work
out cheaper on life cycle costing to buy a new
energy-efficient air conditioner. |
Refrigerators |
01. |
Make
sure that refrigerator is kept away from all
sources of heat, including direct sunlight, radiators
and
appliances such as the oven, and cooking range.
When it's dark, place a lit flashlight inside the
refrigerator and close the door. If light around
the door is seen, the seals need to be replaced.
|
02. |
Refrigerator
motors and compressors generate heat, so allow
enough space for continuous airflow around refrigerator.
If the heat can't escape, the refrigerator's
cooling system will work harder and use more
energy. |
03. |
A
full refrigerator is a fine thing, but be sure
to allow adequate air circulation inside. |
04. |
Think
about what you need before opening refrigerator
door. You'll reduce the amount of time the door
remains open. |
05. |
Allow
hot and warm foods to cool and cover them well
before putting them in refrigerator. Refrigerator
will use less energy and condensation will reduced. |
06. |
Make
sure that refrigerator's rubber door seals are
clean and tight. They should hold a slip of paper
snugly. If paper slips out easily, replace the
door seals. |
07. |
When
dust builds up on refrigerator's condenser coils,
the motor works harder and uses more electricity.
Clean the coils regularly to make sure that air
can circulate freely. |
08. |
For
manual defrost refrigerator, accumulation of ice
reduces the cooling power by acting as unwanted
insulation. Defrost freezer compartment regularly
for a manual defrost refrigerator. |
| Water Heater |
01. |
To
help reduce heat loss, always insulate hot water
pipes, especially where they run through unheated
areas. Never insulate plastic pipes. |
02. |
By
reducing the temperature setting of water heater
from 60 degrees to 50 degrees C, one could save
over 18 percent of the energy used at the higher
setting. |
| Microwave Ovens &Electric
Kettles |
01. |
Microwaves
save energy by reducing cooking times. In fact,
one can save up to 50 percent on your cooking
energy costs by using a microwave oven instead
of a regular
oven, especially for small quantities of food. |
02. |
Remember,
microwaves cook food from the outside edge toward
the centre of the dish, so if you're cooking more
than one item, place larger and thicker items on
the outside. |
03. |
Use
an electric kettle to heat water. It's more energy
efficient than using an electric cook top element. |
04. |
When
buying a new electric kettle, choose one that has
an automatic shut-off button and a heat-resistant
handle. |
05. |
It
takes more energy to heat a dirty kettle. Regularly
clean your electric kettle by combining boiling
water and vinegar to remove mineral deposits. |
06. |
Don't
overfill the kettle for just one drink. Heat only
the amount of water you need. |
| Computers |
01. |
Turn
off your home office equipment when not in use.
A computer that runs 24 hours a day, for instance,
uses - more power than an energy-efficient refrigerator. |
02. |
If
your computer must be left on, turn off the monitor;
this device alone uses more than half the system's
energy. |
03. |
Setting
computers, monitors, and copiers to use sleep-mode
when not in use helps cut energy costs by approximately
40%. |
04. |
Battery
chargers, such as those for laptops, cell phones
and digital cameras, draw power whenever they are
plugged in and are very inefficient. Pull the plug
and save. |
| 05 |
Screen
savers save computer screens, not energy. Start-ups
and shutdowns do not use any extra energy, nor
are they hard on your computer components. In fact,
shutting computers down when you are finished using
them actually reduces system wear - and saves energy |
