Power Resources - Distribution and Uses
- Energy resources or power resources are the primary input in the production of goods and services. The wheels of progress move with the flow of energy. They are one of the critical elements in raising the living standards of any country. Safe, affordable and reliable energy in sufficient quantities is a must for any developing country.
- The two major types of energy resources are:
- Non-renewable energy resources, and
- Renewable energy resources
- The energy resources, which cannot be easily replenished, are known as non-renewable energy resources. Some common examples are:
- Petroleum, and
- Natural Gas
- The energy resources, which can be renewed or replenished, are known as renewable energy resources. Some common examples are:
- Solar Energy
- Wind Energy
- Tidal Energy, and
- Geothermal Energy
- Coal is an inflammable organic substance. It is composed mainly of hydrocarbons and is found in the form of sedimentary rocks. It is also known as ‘Black Gold’.
- First exploration for petroleum in India was undertaken in 1866 in Assam. Oil was first discovered in 1890 in Digboi region of Assam. The areas having possibilities of oil in India extends over 17.2 lakh sq km. Natural gas is in India is majorly obtained from:
- Cauvery Offshore
- Nada in Cambay basin, and
- Tanot in Jaisalmer district in Rajasthan
- The development of hydroelectric power in India started in the last decade of 19th Century. Several multipurpose projects were commissioned. National Hydro-Electric Power Corporation (NHPC) was set up in 1975.
- Being a tropical country, India is lucky to receive abundant sunlight. Solar energy can be used for cooking, water-heating, space-heating, etc. Solar voltaic cells convert solar energy into electricity without any pollution.
- Geothermal energy is the thermal energy generated and stored in the earth.
- Wind energy is the kinetic energy of wind in motion. India has wind energy potential of about 45,000 megawatt.
- Biogas is the most important component of renewable energy in rural areas. Biogas provides smokeless and efficient cooking fuel.
- There is an urgent need for the conservation of energy to protect our environment from drastic changes and to save the depleting resources for our future generations.
Where is the largest solar plant located?Marks:1
The largest solar plant is located at Madhapur near Bhuj.
Mention two areas where petroleum is found in India.Marks:1
Mumbai high and Koyali are two areas where petroleum is found.
What are non-conventional sources of energy?Marks:1
Use of renewable energy sources like solar energy, wind, tide, biomass and energy from waste materials are called non-conventional energy sources.
What is conventional energy?Marks:1
Energy generated from fossil fuels like coal, petroleum and natural gas is known as conventional energy.
How are minerals formed in igneous and metamorphic rocks?Marks:3
Those rocks which were formed first of all in the world are called igneous rocks. While, the altered form of igneous rocks is called metamorphic rocks. Sometimes minerals in the liquid/molten and gaseous forms are pushed upward due to the internal movement of the earth. After passing through the cracks, crevices, faults or joints of the igneous rocks or metamorphic rocks, minerals cool down and solidify on the surface of the earth. Thus, the minerals are formed as a result of the internal movement of the earth and help provided by the cracks in the igneous and metamorphic rocks.
