is more in rainy season since damp air would mean more air mass hitting the blades

 

depends on the height of the tower

 

depends on wind velocity

 

can be increased by planting tall trees close to the tower

 

Sun is considered as an inexhaustible source of energy

 

There is infinite storage of fossil fuel inside the Earth

 

Hydro and wind energy plants are non polluting sources of energy

 

Waste from a nuclear power plant can be easily disposed off

 

its temperature increases

 

larger amount of potential energy is converted into kinetic energy

 

the electricity content of water increases with height

 

more water molecules dissociate into ions

 

It is expected to harness wind power to minimum in open space.

 

The potential energy content of wind blowing at high altitudes is the source of wind power.

 

Wind hitting the blades of a windmill causes them to rotate. The rotation thus achieved can be utilised further.

 

One possible method of utilising the energy of rotational motion of the blades of a windmill is to run the turbine of an electric generator.

 

We are encouraged to plant more trees so as to ensure clean environment and also provide biomass fuel.

 

Gobar gas is produced when crops, vegetable wastes, etc. , decompose in the absence of oxygen.

 

The main ingredient of biogas is ethane and it gives a lot of smoke and also produces a lot of residual ash.

 

Biomass is a renewable source of energy.
