Class 12 Geography - PUNJAB
Mineral and Energy Resources
This chapter explores the distribution, utilization, and conservation of mineral and energy resources in India, specifically focusing on the context of Punjab. Students learn about metallic and non-metallic minerals, conventional energy sources like coal, petroleum, and hydroelectricity, as well as non-conventional sources like solar and wind energy. The chapter emphasizes the need for sustainable resource management and is crucial for Punjab School Education Board (PSEB) Class 12 Geography exams as it features frequently in map-marking questions, short-answer queries, and long descriptive essays on India's industrial foundation.

Metallic Minerals
Minerals that contain metallic elements and serve as a raw material for metallurgical industries, such as iron ore, bauxite, and manganese.
Non-Metallic Minerals
Minerals that do not contain extractable metals, including limestone, dolomite, and mica, which are essential for cement and chemical industries.
Conventional Energy Sources
Traditional sources of energy that are exhaustible over time, such as coal, petroleum, natural gas, and electricity (thermal and hydro).
Non-Conventional Energy Sources
Renewable and eco-friendly sources of energy such as solar energy, wind energy, tidal energy, and biogas.
Energy Conservation
The deliberate practice of reducing energy consumption and using resources efficiently to ensure availability for future generations.

Frequently Asked Questions
What is the difference between metallic and non-metallic minerals?
Metallic minerals yield metals when processed (e.g., iron, copper) and are usually associated with igneous rocks, whereas non-metallic minerals do not yield new metals (e.g., limestone, gypsum) and are generally found in sedimentary formations.
Why are non-conventional energy sources gaining importance in India?
They are renewable, eco-friendly, reduce dependence on fossil fuels, and help in achieving long-term energy security and sustainable development.
Which mineral is known as 'brown diamond' and why?
Lignite (a type of low-grade coal) is sometimes referred to as brown diamond due to its brownish color and high economic value in thermal power generation.
