Our resources

Nowadays we are using petroleum and its derivatives a lot now we can find them but in future??? This is a question for us all so we need to conserve petroleum and its derivatives. We can use alternative sources instead of petroleum and its derivatives this would be a very nice way to conserve petroleum and its derivatives.
There are many alternative sources of energy some of them are
1. Solar energy
Sun's seat and light energy can be felt by us everyday . Solar energy trapped from the sun can be used in solar cells to produce electricity.
Many of these cells are joined into solar panels to generate power for heating and lighting purpose. The technology of utilising solar energy benefits a lot of tropical countries that are blessed with abundant Sunshine solar energy is also used in solar heater , solar cooker , solar dryers besides being used for community lighiting a traffic signals.
Its Advantages
Inexhaustible
Non polluting
Its Disadvantage
Expensive
Difused source, so gets wasted
2.Wind energy
Wind is an inexhaustible source of energy. Wind has been used for grinding grains and lifting water since times immemorial. In Modern Time wind mill , the high speed winds rotate the windmill which is connected to a generator to produce electricity. Wind farms having clusters of such windmills are located in coastal regions and in Mountain passing a strong and steady winds blow
Advantages of wind energy
Non polluting
Low cost production of electricity once set up
Safe and clean
Disadvantage of wind energy
pollution
Wind mills are costly to setup
disturb radio and TV reception
harmful to birds
3.Geothermal energy
Heat energy obtained from the earth is called geothermal energy . The temperature in the interior of the earth Rises steadily as we go deeper. Sometimes this heat energy may surface itself in the form of hot springs. This heat energy can be used to generate power geothermal energy in the form of hot Springs has been used for cooking heating and bathing for several years.

Advantages of geothermal energy
Clean and eco friendly and always available
Disadvantage of geothermal energy
Located far away from the cities and so costly to transport
Tidal energy
Energy generated from tides is called tidal energy. Tidal energy can be hardness by building dams at narrow openings of the sea. During high tide the energy of the tide is used to turn the turbine installed in the dam to produce electricity.
Advantages of tidal energy
 non polluting
inexhaustible
Disadvantage of tidal energy
Destroys wildlife habitat
Difficult to harness

Now it is up to you to save environment. But those all are difficult for children so we can start being simpler. Let us have a discussion on this I will write my ideas and it will it is up to you to think alternative to save environment
Here are some ideas for is by me and my friend Akshitha
We have written all about conserve materials at house

·         old shirts ( also t shirts) can we made into bags ( to know how wait till my next post

·         Leaves and organic matter can be turned into compost and can be used for plants

·         Times of holi and vegetable and flowers can be used instead of chemical colors

·         Last but not least say no to plastic and use jute and cotton bags instead



If you have any alternative ways , please share with us to save our environment
