• As the global population continues to increase and existing fuel supplies begin to run out, countries will have to find ways to increase energy supplies.
• Natural Resources are used in many ways, Energy is the most demanding and consumed resource. Hence Energy Resources play an important role in the development of a country.
• Energy is used to for both Domestic as well as commercial purposes like- it heats homes and offices, cooks our food and powers transport. Much of the energy that is used is in the form of electricity. This is called secondary energy - Primary energy sources, such as fossil fuels or the wind, have been used to generate it.

Different Renewable sources of energy that may be used

Renewable technologies offer a way to increase energy supplies, however they are often more expensive or less efficient at producing energy than fossil fuels. Therefore they may require government subsidies.

Biomass

• Derived from the waste products of living things (ex: cow dung)
• Plants burn the waste and non recyclable stuff to generate electricity/energy
• UK uses

Hydroelectric power

• River water is trapped behind a dam in a reservoir and the water is released in a controlled manner to spin the blades of a turbine and produce electricity
• UK uses
• US - hoover dam

Wave power and tidal power

• Wave energy harnesses the power of small movements on the surface of the sea.
• The technology is new and currently expensive.
• UK uses less

Geothermal

• Use heat within the earth to generate electricity
• Iceland uses
