AWARENESS PROGRAM
FOR ENERGY CONSERVATION
Energy
is essential to life and the key to human progress. Its conservation is
essential in the Modern Industrial Societies, As the population in our
country grows and the pace of Urbanization increases, energy use is
bound to increase. At present, India
is the fifth largest consumer of energy in the world. Do you know what
the total electricity generation by power utilities was in 1947? It was
meagre 1362 MW. It has increased 150 times in about 65 years projected,
2012 fig. 212000 MW. The power shortages in the country are so large
that almost 10000 MW of additional capacity is required every year. This
alone would require a capital investment of the order of Rs. 40,000
Crore per year on generation and matching investment would be required
on transmission and distribution networks. Any idea, where this
magnitude of investment can be sourced from?
Energy and Environment
Many
major environmental problems we face today are linked with the energy
sector. To a large extent, the energy production technologies and energy
use are responsible for green house gas emission, global warming and
the consequent climate change.
Energy Conservation
Energy
Conservation is cheaper and more environmentally benign compared to
increased energy Production. We need to encourage it amongst all
categories of consumers.
Energy Conservation is a practice for –
• ensuring judicial usage of energy, and
• decreasing the quantity of energy consumed while achieving a similar outcome of end use.
Energy
Conservation can be a result of several processes or developments, such
as increase in productivity, technological progress resulting in more
energy efficient technologies and most importantly a positive attitude
towards efficient energy usage.
Sector-wise Electricity Consumption
A
report of the National Development Council Committee on power reveals
sector-wise consumption of electricity in our country, Industrial
consumption (~36.5%) is the highest, followed by agricultural (~31%),
domestic (~20%) and commercial (~6.5%).
SSHI will emphasize on the domestic and commercial sectors in the first phase of awareness program.
Domestic and Commercial Sectors
Domestic sector consisting of individual house hold. Electrical power is mainly used for the following purposes.
• cooking.
• lighting.
• cooling (fans, refrigerators, desert coolers, air conditioners etc.)
• heating (geysers, water heaters, room heaters etc.).
• domestic appliances (washing machines for dishes and clothes, toasters, mixers,grinders,entertainment systems, computers etc.)
• building air - conditioning and limited use for heating (HVAC).
• swimming pool water filtering amongst the urban elite etc.
In
the commercial sector which consists of offices, shops, schools,
hospitals, banks, etc., lighting and HVAC (Heating, Ventilation,
Air-conditioning and Cooling) constitute the bulk of electricity use.
Huge
quantities of electrical energy can be saved for less than the cost of
generating and transmitting the same amount of electricity if we
understand that
“Consumers don’t want to buy electricity or fuel they want well-lit rooms and hot tea”.
Except
in the form of food, no one needs or wants energy as such. That is to
say, no one wants to eat coal or uranium, drink oil, breathe natural gas
or be directly connected to an electric supply! What people want are
energy services – those services which energy can provide uniquely in an
efficient and desirable manner. For instance, we should be happy to use
an energy efficient Fridge versus a standard fridge provided that both
provide the same services (i.e., they both keep our food cool). Thus,
the more efficient the ways of providing energy services required by the
consumers are, the greater would be the energy savings. Air
conditioning is more prevalent in the commercial sector than in the
domestic sector. In both these sectors, the bulk of energy consumption
is within buildings and appliances. We know that buildings consume a
large chunk of the available energy and rely more on artificial lighting
than on natural lighting and ventilation.
There
are various opportunities and techniques available for reducing energy
consumption such as efficient motors and transformers, day lighting,
variable speed drives, solar hot water systems etc.
Lighting Efficiency Improvement
Lighting, of course, is a very ‘visible’ consumer of energy. Almost two thirds of the lighting points in India are fitted with incandescent lamps (ordinary bulbs).
• Use Compact Fluorescent Lamps (CFLs) throughout your home to provide high quality and high efficiency lighting. A22
Watt CFL has about the same light output as 100 Watt incandescent bulb.
CFLs use 50-80% less energy than incandescent bulbs. CFLs use 1/3rd the
electricity and last upto 10 times as long as the incandescent bulbs.
CFLs
reduce Air and Water Pollution, A single incandescent bulb replaced
with a CFL will keep half a tonne of Carbon dioxide out of the
atmosphere over its life time.
Improving Energy Efficiency of Building & Appliances
Much of energy use occurring within buildings consists
of requirements for space heating / cooling, water heating, cooking, lighting and appliances.
Commercial
building energy consumption can be reduced by an average of 55%
primarily through controlling lighting and air conditioning loads.
Specific technological measures that can be taken to conserve energy within buildings include;
• Improved levels of insulation in walls, roofs and floors to reduce heat losses through these elements.
• Draught-proofing
and heat recovery systems to reduce heat loss through ventilation
whilst retaining sufficient fresh air within the building.
• more
efficient boilers that require a smaller fuel input to achieve a given
level of space or water heating, together with improved insulation of
pipes to reduce heat losses.
• energy-efficient
lights that require much smaller amounts of power to provide a given
level of illumination, e.g., CFLs along with the choice of the lamp
type/number according to the needs of various areas within a building
envelope.
energy
efficient appliances such as refrigerators, cooling ranges, washing
machines, TV sets and hi-fi equipments in the domestic sector is
improving day by day; More efficient computers, copiers and other
business equipment are being used in the commercial and institutional
sector. These consume less energy whilst delivering the same level of
services as their inefficient predecessors.
Community Energy Planning
Municipal
Governments, planners, developers, businesses and residents should make
sure that home and communities are built in a way that conserves
energy. This can be done by encouraging clustered housing, implementing
building codes for improving energy efficiency, making mandatory the use
of double glazed windows particularly in buildings having energy
consumption above 500 KW etc. This is also being mandated in India according to the National Building Energy code for Indian buildings.
What you can do at the Individual Level
A
great deal of energy can be saved by us in our homes. Let us begin by
posing some questions. At the individual level, are you not concerned
about your rising electricity bills and energy costs? You also want to
be responsible to the environment. What kind of efforts do you need to
make? Will your efforts pay off? How much energy and money will you
actually save?
Points to Remember
1. Switch off lights when not needed.
2. Use high efficiency home and office equipment and appliances.
3. Electricity saved means electricity generated.
4. 1 unit saved by the end user is equal to 2 units generated at the power plant.
5. Conserve energy to reduce energy costs and protect the environment.
