IntroductionIntroduction

• Electricity plays an important part in our lives.• Without electricity, one can only imagine how

difficult and tedious life would be.– Without electricity

• nights would be spent in darkness• the internet is unthinkable and it would be as if everybody

were back, living in the Stone Age. – But as human ares, when we have, we waste. – Are we going to wait till the end of the world before we

learn about our mistakes? – By then, all will be useless, so treasure what you have

now and CONSERVE!• This presentation will briefly cover the wastage

and conservation of electrical energy

Contributors to Contributors to Electricity ProductionElectricity Production

• Fossil Fuels 60%– Coal 25%– Oil 15%– Gas 20%

• Hydro Electric Power 20%• Nuclear 11%• Other 8%

FOSSIL FUELS ARE MAJOR CONTRIBUTERS TO PRESENT DAY ENERGY PRODUCTION AND THESE ARE NOT GOING TO LAST MUCH

Fossil Fuels: What We Have??Fossil Fuels: What We Have??

• Proved Reserves• Oil: 1,119 to 1,317 billion barrels • Gas: 6,183 - 6,381 trillion cubic feet = 1,161 billion barrel oil equivalent • Coal: 997,748 million short tons = 4,416 billion barrel oil equivalent• • Daily Production Rates• Oil: 84 million barrels per day• Gas: 19 million barrels oil equivalent per day • Coal: 29 million barrel oil equivalent per day

• Years of production left in the ground with the most optimistic proved reserve estimates

• Oil: 43 years • Gas: 167 years • Coal: 417 years

These are 2006 Estimates the consumption is These are 2006 Estimates the consumption is exponentially increasing and the reserves will last exponentially increasing and the reserves will last for much less time then expected above.for much less time then expected above.

How Do We Waste Electricity?How Do We Waste Electricity?

• City Lights– Major source of electricity wastage

• Inefficient machines– Conversion of electrical energy to mechanical and

other form of energy is not efficient and more than 20% of electricity is wasted in this operation

• Careless Attitudes of Consumers– Consumers mistakenly think that they have right to

waste energy when they are paying for it! – This attitude is not correct, we have no right to use

the resources which are right of our future generations

Environmental Consequences!!Environmental Consequences!!

• Not only we are wasting the precious natural resources but we are causing disastrous effects on our climate

• When more electricity is produced more CO2 is pumped into the atmosphere.

• This is causing– Green House Effect– Making Climate Changes– Disturbing the ecology of the Planet Earth

How Should We Save?How Should We Save?Start From Our Homes!!!Start From Our Homes!!!

• Electric Bulbs– Major contributor in electricity wastage. Only 5% converted into light 95% wasted

in heat– Use efficient bulbs called “Energy Savers”

• Fan– Waste electricity in overcoming friction and in generation of heat at regulator– Use properly lubricated fans with at high speed.

• Refrigerator– Ovoid frequent opening of door

• Electric Iron– Cultivate culture to iron cloths on weekly basis, it will not only save energy but

time also

• TV / DVD– TV / DVD should be turned on only when being watched.

• Air Conditioner– Major contributor of energy crisis in hot countries. Should be very carefully used

• Washing Machines– Loading of dirty linen should be such that maximum machine capacity is utilized.
