2 CLASSIFICATION OF ENERGY SOURCES
1. Renewable Energy Resources
- Non-conventional sources of energy.
- Alternate sources of energy.
- Relatively new techniques developed by man.
Solar Energy – man recently learnt how to harness solar energy. Sun there billions of years to
come and this energy cannot be exhausted easily.
- We can use the suns directly. To concentrate its heat, by using mirrors.
- Sunny places used to make furnaces or to generate electricity.
Solar Panels – made up of special material that absorb sunlight, convert the solar energy into
chemical and electrical energy which is further used for various purpose like cooking, heating,
lighting etc.
NOTED:
Commercial forms of solar cooker, solar water heaters, solar lights, solar cells etc. are now
available.
Community lighting and pimping of water is also done by solar energy in many rural areas
where electricity is not available.
Biomass – it’s a chemical energy stored in it.
- It is burnt to provide heat or electricity or converted to liquid or gaseous bio-fuel.
- Wood, Wood waste, animal excreta like cow dung etc.
Bio-energy – the inexpensive and easily available cow dung is collected and processed in a
special manner to release a gaseous fuel which is primarily for cooking and lighting purposes.
- Less polluting and more efficient than the traditional cow-dung cakes.
Hydel Energy – kinetic energy is the energy possessed by an object due to its movement.
- Used to run machines, turbines and produce electricity.
