Energy Resources

"Energy Resources", the simple way of getting energy by which we generate electrical power.
There are number of energy resources available.Some are listed here-


1.Primary Resources
1.1 Fossil fuels
1.2 Oil
1.3 Coal
1.4 Nuclear Power
2.Renewable Resources
2.1 Hydropower
2.2 Biomass and Biofuels
2.3 Solar Power
2.4 Wind Power
2.5 Geothermal

-> Sun is the biggest energy resource for Earth.
-> Primary resources are limited but Renewable resources can be used in an unlimited way.
Most of the electrical energy is generated by Primary Resources.
Thermal Power Plants use the Primary Resources.The energy is generated in Thermal Power Plants by burning the coal and oil.

Nuclear Power:- Nuclear power is generated using Uranium.It produces about 11% of the world's energy need.It produce a huge amount of energy using less amount of fuel.It is a pollution free process.

HydroPower:- In HydroPower the running water is used for the generation of electricity.

Biomass and Biofuels:- Boifuels include the fuel made from living goods or their wastes like Biodiesel, Bioethanol.


Solar Power:- The energy generated by the light of Sun is called Solar Power.The Sun is 150 million kilometers far from Earth and the biggest energy resource for Earth.The electricity from Sun is generated by
using Solar Panels.

Wind Power:- In this the power of wind is used.In this the Turbine is rotated by the blowing wind and energy is generated.

Geothermal:- In Geothermal Power the heat of Earth is used for the generation of energy.The center of Earth is 6000 degrees Celsius hot enough to melt the rock and few kilometers down the temperature increases one degree per 30-50 meters go down.

There is one more type of energy resource called Tidal Power. In this the power of Tides is used.Tide moves twice in a day and carry huge amount of
water.The barrages are used to store the water and then it is used to generate the energy.
