Useful tips to Save Energy
1. Lighting
•
Turn off the lights when not in use.
•
Take advantage of daylight by using light-coloured, loose-weave curtains on your windows
to allow daylight to penetrate the room. Also, decorate with lighter colours that reflect
daylight.
•
De-dust lighting fixtures to maintain illumination.
•
Use task lighting; instead of brightly lighting an entire room, focus the light where you
need it.
•
Use electronic ballast chokes in place of conventional copper chokes.
•
Use LED Lamps instead of conventional incandescent bulbs. A 16w LED bulb can be as
bright as 150w halogen lamp. LED lamp consumes 1/3rd of CFL energy and 1/30th
energy of incandescent bulbs. The lifespan of incandescent lamps is around 1000 hours
while the lifesplan of CFL is 8,000 hours and lifespan of LED lamps is around 25,000
hours. LED Lamps are Mercury free and their lifetime cycle is unaffected by switching
ON and OFF operations.
2.Fans
•
Replace conventional regulators with electronic regulators for ceiling fans.
•
Install exhaust fans at a higher elevation than ceiling fans.
•
For exhaust fans in diary/poultry industry usage of multi fan axial fans leads to low energy
consumption with low noise levels.
•
Use BEE star rated energy efficient fans.
3.Electric Iron
•
Select iron boxes with automatic temperature cutoff.
•
Use appropriate regulator position for ironing.
•
Do not put more water on clothes while ironing.
•
Do not iron wet clothes.
•
Use BEE star rated energy efficient iron box.
4.Kitchen Appliances
Use Efficient electrical appliances.
Use always BEE star rated efficient electrical appliances.
a) Mixers
•
Avoid dry grinding in your food processors (mixers and grinders) as it takes longer time
than liquid grinding.
b) Microwaves ovens
•
Avoid baking large sized food items.
•
Unless you are baking breads or pastries you may not need to preheat.
c) Induction Stove:
•
Consumes 50% less energy than conventional electric coil/ hot plate.
•
Takes less time to boil water than conventional electric stoves.
d) Electric Stove:
•
Turn off electric stoves several minutes before the specified cooking time.
•
Use flat-bottomed pans that make full contact with the cooking coil.
e) Refrigerator:
•
Do not open the door of the refrigerator frequently.
•
Make sure your refrigerator or door seals are airtight.
•
Don’t keep your refrigerator or freezer too cold.
•
Avoid putting hot or warm food straight into the fridge.
•
Retire old/inefficient refrigerators and buy new energy efficient star rated energy efficient
refrigerators.
•
Don’t leave the refrigerator door open for longer than necessary as cold air will escape.
•
Leave enough space between your refrigerator and the walls so that air can easily circulate
around the refrigerator.
•
Use BEE star rated energy efficient refrigerators.
5.Washing Machine:
•
Avoid washing with half loads.
•
Use optimum quantity of water.
•
Use timer facility to save energy.
•
Prefer natural drying over electric dryers.
•
Dry full loads or reduce drying time for partial loads.
•
Use BEE star rated energy efficient washing machines.
6.Electronic Devices:
•
Do not switch on the power when TV and Audio Systems are not in use i.e., idle operation
leads to an energy loss of 10 watts/device.
7.Air Conditioners:
•
Prefer air conditioners having automatic temperature cut off.
•
Keep regulators at “low cool” position or in energy efficient mode.
•
Make sure that the joints at windows and doors are properly sealed and insulate the room against
loss of temperature.
•
Use BEE star rated energy efficient air conditioners.
8.Computers:
•
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.
•
Optimize brightness of monitors as bright light consumes more power. Studies have proved that
minimum brightness consumes 11 Watts while maximum brightness in monitors consumes as
much as 25 Watts.
9.Water Heaters:
•
Set your thermostat at 120 degree Fahrenheit or lower.
•
In addition to the water heaters install solar water heating systems.
10.Solar Rooftop off-grid Lighting systems :
•
Use solar rooftop off-grid Lighting systems (with battery back-up) as unlimited sunlight is
available at free of cost everywhere in India.
•
The Domestic sector accounts for 30% of total energy consumption in the
country. There is a tremendous scope to conserve energy by adopting simple
measures.

WHAT IS DEMAND SIDE MANAGEMENT?
• Demand Side management is a mechanism to influence customer’s
CAPABILITY and WILLINGNESS to reduce electricity consumption.
• Demand Side Management is a utility program aiming to fine-tune
consumers’ energy consumption pattern, according to the utility’s
energy production and distribution capacity.
•
Demand-side management (DSM) programs consist of the planning,
implementing, and monitoring activities of electric utility that are
designed to encourage consumers to modify their level and pattern of
electricity usage.
• Demand side management relies on a combination of using high
efficiency equipment and efficient use of electricity through good
operating practice.
• Demand Side Management (DSM) is the implementation of policies
and measures which serve to control, influence and generally reduce
electricity demand. DSM aims to improve final electricity-using
systems, reduce consumption, while preserving the same level of
service and comfort.
OBJECTIVES OF DSM

1: Reliability and Stability




DSM provides enhanced reliability to the energy system by reducing
overall demand through energy efficiency and by reducing peak demand
through dispatchable programs.
It also reduces transmission and distribution costs relative to a supply side
resource
DSM increases diversity of energy sources
2: Low Cost/Affordability




The cost of DSM is technology specific and varies relative to other supply side
resources
Dispatchable DSM programs can be called when their cost is lower than
alternative market purchases
Cost-effective resource planning can ensure that DSM is only procured up to the
point where it is cheaper than supply alternatives
DSM can also help low-income customers reduce their energy costs
Types of DSM Programs

Following three factors reduce energy consumption
(kWh) and peak demand (kW), however, emphasis
differs
- Energy Efficiency – emphasis is on reducing overall energy
consumption and also peak demand over several years.
- Peak Load Management – emphasis is on reducing peak demand
consistently over a season.
- Demand Response – emphasis is on reducing peak demand for
short periods of time for a few days during the year.
