ENERGY CONSERVATION AND ITS UTILITY……..!!!!

Energy conservation refers to

reducing energy consumption through

using less of an energy service. Energy

conservation differs from

efficient energy use, which refers to

using less energy for a constant service.

Enacted in October 2001.

Become effective from 1st march

2002.

Bureau of Energy Efficiency

operationalized from march 2002.

Energy Conservation

Act.

*TYPES OF ENERGY

ENERGY CAN BROADLY DIVIDED INTO 2 CATEGORIES:

1.Renewable Energy.

2.Non-Renewable Energy.

*

Non renewable energy

cannot be generated

again and again.

E.g. Energy generated

from combustion of

fossil fuels, energy

from coal and gas etc.

RENEWABLE ENERGY:

Renewable energy can be

generated continuously

practically with out delay

of source like

*Solar energy

*Wind energy

*Geothermal energy

*Hydro energy

*Biomass

*Tidal

*SOLAR POWER

*Solar power is a promising, renewable energy

resource than can be turned into electricity, and it

is used in many toys and even home heating.

WIND ENERGY

Wind power is increasingly being used as a clean source of renewable energy.

Turbines harvest wind on wind farms and generate electricity.

*Why To conserve it……???

We have limited resources available on earth.

Our demands are continuously increasing day

by day.

It is possible that someday most of the non-

renewable resources will be exhausted and we

will have to switch over to alternate energy.

We save our money

when we save energy.

We reduce pollution

when we save energy.

We save our energy

when we save energy.

*Ways to conserve energy……!!

Energy will be conserved in

many appliances like

1.Home appliances.

2.Industries.

3.Work places and so on……..!!

As we seen in home

appliances…..!!

There are so many

ways like lightning,

cooling, heating,

water heating, etc.,

In lightning,

how to

conserve

energy….!

Watts Light Cost Life No of Units

Lumens Rs. Hours hrs/day /Year

Bulb 60 700 10 1000 4 88

CFL 15 700 200 7000 4 22

The job of your home air

conditioner is move heat

from inside your home to

the outside, thereby

cooling you and your

home. Air

conditioners blow

cool air into your home by

pulling the heat out of

that air. The air is cooled

by blowing it over a set of

cold pipes called an

evaporator coil.

* If we seen in cooling, More than using A.C we can use

whole house fan…!

* Instead of air-conditioning, consider installing a

whole-house fan. Whole-house fans work in many

climates and help cool your home by pulling cool

air through the house and exhausting warm air

through the attic. Use the fan to cool down and

your home will stay cooler through the hotter

times of the day without using the fan.

In Industries, the energy can

be utilized in so many ways

like in

1. Thermal utilities.

2. Electrical utilities.

*

A boiler is water containing vessel

which transfers heat from a fuel source

(oil, gas, coal) into steam which is

piped to a point where it can be used

to run production equipment, to

sterilize, provide heat, to steam-clean,

etc.

• Preheat combustion air with waste

heat

• Inspect oil heaters for proper oil

temperature.

• Use boiler blow down to help warm

the back-up boiler.

• Recycle steam condensate.

* Insulation:

It slows heat losses

from a building, either

by using bulky,

lightweight materials

such as glass-fiber or

wool between framing

elements, and

sometimes by using

reflective materials to

reflect heat back into

the building.

*As in Electrical

utilities…..!!

There are

Motors, Fans, Drivers,

Blowers, Pumps etc

Blowers:

• Minimize blower inlet

and outlet obstructions.

• Clean screens and

filters regularly.

• Minimize blower

speed.

• Use low-slip or no-slip

belts.

• Check belt tension

regularly.

Fans:

• Use smooth, well-

rounded air inlet cones

for fan air intakes.

• Avoid poor flow

distribution at the fan

inlet.

• Minimize fan inlet and

outlet obstructions.

• Clean screens, filters,

and fan blades

regularly.

RECYCLE - compositing waste materials into new products to prevent waste of potentially useful materials.

Turn off all electronic devices that are not in use. Not only turn them off but try to remember to unplug them. You will be surprised how much you will save with this simple step!

Replace old light bulbs with energy saving fluorescent bulbs. They may cost more, but will save you much more in the long run.

*WHAT WE CAN DO….??
