Study Notes

Minerals

Minerals are natural substances formed through geological processes without human intervention.
Over 3,000 types of minerals exist, classified as metallic (ferrous and non-ferrous) and non-metallic based on composition.
Metallic minerals contain metal in raw form, characterized by hardness and conductivity.
Ores are rocks from which minerals are extracted, lacking a definite composition.

Petroleum and Natural Gas

Petroleum, also known as "black gold," is processed into various products including diesel, petrol, and plastics.
Major petroleum-producing countries include Iran, Iraq, Saudi Arabia, and Qatar, with the USA, Russia, Venezuela, and Algeria as significant contributors.
In India, major petroleum sources are found in Digboi, Bombay High, and river deltas of Krishna and Godavari.
Natural gas is typically found alongside petroleum and serves as a clean energy resource with diverse applications.
Leading global producers of natural gas are the USA, Russia, Iran, Qatar, and China; major reserves in India are located in Mumbai High, Krishna Godavari, Cambay, Tripura, and Assam.
Natural gas emits fewer pollutants compared to coal and fossil fuels, making it a cleaner option for energy generation.

Hydel Power

Hydel power is generated through the gravitational force of falling water, underscoring the use of dams to store and release water.
Paraguay, Norway, Brazil, and China are the leading producers of hydel power globally.
Important hydel power stations in India include Bhakra Nangal, Gandhi Sagar, Nagarjunsagar, and the Damodar Valley projects.

Wind Energy

Wind energy is produced by using windmills that harness wind power to generate electricity.
Wind farms are typically located in coastal and mountainous regions with consistent high-speed winds.
Key countries in wind energy production include the Netherlands, Germany, Denmark, the UK, the USA, and Spain.

Nuclear Power

Nuclear power is derived from fission processes of radioactive elements like uranium and thorium.
The USA and Europe are major producers of nuclear energy, with large deposits of uranium located in India, particularly in Rajasthan and Jharkhand.

Tidal Energy

Tidal energy is generated from the movement of tides by constructing dams at sea openings.
Major tidal energy sources are found in Russia, France, and the Gulf of Kachchh in India.

Biogas

Biogas is produced by decomposing organic waste in biogas digesters, resulting in a mixture of methane and carbon dioxide.
It is an effective fuel for cooking and lighting and supports the production of organic manure.
Energy harnessing remains a complex and costly challenge despite the abundance of available resources.
