Due to the exponential growth of the population, the demand for energy is increasing at very high rate. Therefore, it is important to use these energy resources wisely and in a sustainable manner.
The generation of nuclear power is being geared up to contribute significantly to the overall availability of energy.
Introduction
- India is one of the fastest-growing economies and therefore, the energy demand is also growing continuously. India has exploited almost all sources of energy such as hydroelectricity, thermal energy, nuclear energy, and solar energy. wind energy, etc.
- Energy resources can be defined as materials or elements that can be used to produce energy. Energy resources are those from which energy is derived.
Classification of Energy Resources
- Energy resources, on the basis of traditional use, can be classified into conventional and non-conventional energy resources.
Conventional Resources
- These resources are non-renewable and ecologically hazardous.
- For a long time, these energy sources have been used extensively to meet energy demands.
Some conventional sources of energy are as follows
Coal
- Coal is one of the most important primary fossil fuels. Coal is a sedimentary deposit composed predominantly of readily combustible carbon.
- Coal is a natural resource that can be used as a source of energy and in the production of coke for metallurgical processes.
- Coal is a major source of energy in the production of electrical power using steam generation.
Based on carbon content, coal can be categorized into different types:
- Anthracite: This high-quality coal boasts the highest calorific value, containing 80% to 95% carbon. It ignites slowly with a blue flame and is found in small quantities in Jammu and Kashmir.
- Bituminous: With a low moisture content and 60% to 80% carbon, bituminous coal has a high calorific value. Deposits are found in Jharkhand, West Bengal, Odisha, Chhattisgarh, and Madhya Pradesh.
- Lignite: Characterized by 40% to 55% carbon content, lignite is often brown and has a high moisture content, producing smoke when burned. Deposits are located in Rajasthan, Lakhimpur (Assam), and Tamil Nadu.
- Based on usage, coal is classified into coking and non-coking types.
- Regarding the origin, Gondwana Coal, approximately 250 million years old, constitutes 98% of India’s total coal reserves and 99% of its production. It is moisture-free but high in phosphorus and sulfur, providing superior-quality coal for metallurgical purposes.
- The Damuda series, part of the Gondwana coal, dominates India’s coal production, particularly in the valleys of rivers such as Damodar, Mahanadi, Son, Godavari, Wardha, Indravati, Narmada, Koel, Panch, Kanhan, and others. Major areas in Madhya Pradesh, including Singrauli, Sohagpur, and Umaria, contribute significantly to this coal series.
- Tertiary coal, aged 15 to 60 million years, has a low carbon content and is mainly found in extra-peninsular regions such as Jammu and Kashmir, Himachal Pradesh, Assam, and Arunachal Pradesh. Generally, coal has low carbon and high percentages of moisture and sulfur, with important tertiary coal areas in parts of Assam, Meghalaya, Arunachal Pradesh, Nagaland, Darjeeling in West Bengal, Jammu and Kashmir, Uttar Pradesh, Rajasthan, and Kerala.
- Tamil Nadu and the Union Territory of also bear Tertiary coal is found in Neyveli (Tamil Nadu famous for lignite) and Palana (Rajasthan). It is estimated that the largest reserve of lignite is in Mannargudi of Tamil Nadu.
