Types of Energy

• Energy can be broadly divided into two categories:-

• Renewable Energy ie.,Non-Conventional Energy

• Non-Renewable Energy ie.,Conventional Energy

Renewable Energy

• Renewable energy can be generated continuously practically without decay of source.

• Conventionally available• E.g.:-

»Solar Energy»Wind Energy»Geothermal Energy


Renewable Energy (Contd.)

Solar Energy

• Solar energy can be converted into electrical energy by using solar panel, or alternatively, by used as thermal energy using solar water heaters, solar cookers .

• Solar Panels Solar Trough



Wind Energy• Wind energy can be converted into

electrical energy by the wind mills and can be used for many purposes.



• The development of wind power in India began in the 1990s,and has significantly increased in the last few years.• As of 31 October 2009 the installed capacity of wind power in India was 11806.69 MW, mainly spread across Tamil Nadu (4900.765 MW),Maharashtra (1945.25 MW), Gujarat (1580.61 MW), Karnataka (1350.23 MW), and other states (3.20 MW) .

Wind power in india


• It is estimated that 6,000 MW of additional wind power capacity will be installed in India by 2012.

• India has the fifth largest installed wind power capacity in the world .


Importance of wind energy

• The wind is converted into electricity creating wind energy so that it can be used as a source of power.•Wind energy has little to no damaging affect on the environment unlike other energy sources do, such as coal, gas, oil and nuclear generated power.


Advantages of wind energy

• Wind energy is friendly to the surrounding environment, as no fossil fuels are burnt to generate electricity from wind energy.• Wind turbines are a great resource to generate energy in remote locations, such as mountain communities and remote countryside.


• Newer technologies are making the extraction of wind energy much more efficient. The wind is free, and we are able to cash in on this free source of energy.

• wind energy is that when combined with solar electricity, this energy source is great for developed and developing countries to provide a steady, reliable supply of electricity.


Disadvantages of wind energy•The main disadvantage regarding wind

power is down to the winds unreliability factor. In many areas, the winds strength is too low to support a wind turbine or wind farm, and this is where the use of solar power or geothermal power could be great alternatives.


• Wind Energy is non-dispatchable. This may also put a spanner in depending upon wind power as a primary energy supplier.

• Wind turbines generally produce allot less electricity than the average fossil fuelled power station, requiring multiple wind turbines to be built in order to make an impact.


Geothermal Energy

• A lot of energy exists inside earth crust .

• Natural hot water springs are a good source of getting such energy.


Non Renewable Energy

• Non renewable energy cannot be generated again and again.

• E.g. energy generated from –combustion of fossil fuels–coal –gas


Why to Conserve?

• We have limited fuels available on earth.• Our demand for energy is increasing day-

by-day. • It is possible that someday, most of fuels

will be exhausted, and we will have to switch over to alternate energy

• .


Limited Fuels• At present consumption levels- • Crude oil will last only for 40 years. • Gas will last for 60 years. • Coal will be finished in nearly 200 years.

Ever thought of life without oil and gas?


Increasing Consumption

• Furthermore, our consumption is increasing day-by-day.

• This means fuels will last much earlier than expected.

• The only solution is …..

ENERGY MANAGEMENT


Energy Conservation in India

• In India, government has passed “Energy Conservation Bill, 2001” for better utilization of energy and conservation of the same.

• By this act, it is mandatory for energy intensive sectors to get their “Energy Audit” conducted by accredited energy auditor.


Energy Conservation in India (Contd.)

Bureau of Energy Efficiency(BEE):• This body keeps watch on energy consumption patterns, develops

norms for appliances etc. • It also organizes different competitions e.g. poster & slogan

competition etc. for children.

Star Ratings:• Star Ratings BEE has also initiated “Star Rating System” for electrical

appliances e.g. refrigerator, CFL, geysers etc. • In this system, 1-5 stars are allotted to products depending on their

energy efficiency. • A five star product means that it consumes least energy in its

segment.


What Can We Do?• We, the children can do our bit to

save energy.

• We should not waste energy in school or at home.


What Can We Do? In School

• Always switch off lights and fans while going out of the class.

• In computer lab, we should switch off computers before going out of class.

• If there are less students in the class, we should sit together so that some fans can be switched off.


What Can We Do? At Home

• We should not keep light and fan unnecessarily switched on.

• We should not open fridge door frequently.

• We should not open fridge door for long time.

Watching interesting programs on TV is interesting, but afterwards, TV should be switched off.

While going to purchase new products, e.g. refrigerator, geysers, CFL etc., we should insist upon purchasing a five star product rather than cheap and energy waster product.


How will it help?• Take an example: We replace one 100W bulb with a

13W CFL.

• Let us assume electricity is available for Rs. 3.00 per unit, and this bulb is used for 6 Hours a day. The annual saving would be….

Power Saving:• Power saved: 100W-13W =• 87W =87W X 6 Hours X 365 Days =17520 WH • =17.520 kWH or Units =Rs. 52.56 Say Rupees 50 per

one bulb replaced.


How will it help? (Contd.)

• So, Remember to replace light bulbs with CFLs so electricity could be available for more time.

• You can also ask your parents for a chocolate or some other gift after reducing your electricity bill.

What Else can be Done?

• We should discuss energy conservation with our friends and tell others how can we reduce energy consumption.
