 UGC NTA NET Exam Preparation: Energy Resources|Unit-9|Part-12|


An energy resource is something that can produce heat, power, move objects or produce electricity. the pace of industrialisation of contemporary third world countries is absolutely reflected in their pattern of production and consumption of energy. energy resources can be divided into renewable and non-renewable sources.

Renewable Energy Resources: our renewable energy resources will never run out. their supply is not limited. there are no fuel costs either and typically generate far less pollution than fossil fuels. water, wind,solar energy, geothermal energy etc are renewable resources.

1. Solar Energy: sun is a big source of energy. the energy that we get from the sun is called solar energy. all the natural phenomena like the flowing of wind, water cycle, etc are possible due to solar energy. Now-a-days, solar energy is being used to cook food with the help of solar cookers, heat water, light streets, pump water for irrigating etc.

2. Wind Energy: Wind is converted into electricity through wind mills these wind mills are generally established only at places where most of the day experience strong winds
The energy from these wind mills is used for grinding gain pumping water and to produce electricity in india many windmills have been set up in different states such as Maharashtra, Tamil nadu, Karnataka, rajasthan, kerala, west bengal, odisha and gujarat.

3.  Biomass Energy: It is waste material from plants or animals that is not used for food or feed. it can be waste from farming like wheat stalks or horticulture like yard waste, food processing like corn cobs, animal farming like manure rich in nitrogen and phosphorus, or human waste from sewage plants.
it is used in various industrial processes, like energy production or as raw materials for manufacturing chemicals. it can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel.
4. Geothermal Energy: it is that heat from the earth from the shallow ground to hot water and hot rocks found a few miles beneath the earth's surface and from molten rocks. geothermal heat pumps can tap this resource. it consists of a heat pump, an air directly system and a heat exchanges system of pipes. all these equipment are buried the shallow ground near the building and finally electricity has been generated through these wells.

Non-Renewable resources: non-renewable resources are those natural resources that are available in limited quantity. these resources cannot be renewed or replenished in short duration. therefore, they are known as exhaustible resources. for e.g., coal, natural gas, petroleum etc.

Nuclear Energy: The fuel used for nuclear energy is generally uranium, which is in a limited supply. production of electricity from nuclear energy does not release carbon dioxide. thus, use of nuclear energy is safe for the environment.

although, there is a great deal of radiation danger associated with nuclear energy. it is capable of causing genetic disorders,. thus, if someone is once exposed to these radiations, it can affect the generation to come adversely.
