India Primary Energy Source Explained
This question asks about the main source of energy used in India, according to information from the Ministry of Power as of May 2023. Understanding the primary energy source is crucial for grasping how a country generates its electricity and meets its energy demands.
Analyzing India's Energy Sources
Let's look at the options provided and their significance in India's energy landscape:
- Solar Energy: This involves harnessing energy from sunlight using technologies like solar panels. While India has made significant strides in solar energy adoption due to its abundant sunshine and focus on renewables, it hasn't yet surpassed other sources as the overall primary one.
- Nuclear Energy: Generated through nuclear reactions, nuclear energy provides a stable and carbon-free power source. India has a growing nuclear power program, but its contribution to the total energy supply is relatively smaller compared to the leading source.
- Thermal Energy: This is energy generated by burning fossil fuels, primarily coal, but also natural gas and oil. India has vast coal reserves, making thermal energy the backbone of its electricity production for many decades. This source consistently provides the largest share of the country's power.
- Hydroelectric Energy: This renewable energy source uses the power of moving water (like rivers) to generate electricity. While important, hydroelectric energy potential is geographically dependent, and its share fluctuates. It is not the primary source nationwide.
Identifying the Primary Energy Source
Based on data and reports typically issued by the Ministry of Power, and reflecting the situation around May 2023:
- Thermal energy, predominantly from coal-fired power plants, constitutes the largest portion of India's energy production.
- The reliance on coal is due to factors like availability, established infrastructure, and cost-effectiveness, despite increasing efforts towards diversification and renewables.
Therefore, according to the Ministry of Power's assessments, thermal energy remains the primary source of energy in India.
Important Questions from Sources of Energy
It is possible to produce algae based biofuels, but what is/are the likely limitation(s) of developing countries in promoting this industry?
1. Production of algae based biofuels is possible in seas only and not on continents.
2. Setting up and engineering the algae based biofuel production requires high level of expertise/technology until the construction is completed.
3. Economically viable production necessitates the setting up of large scale facilities which may raise ecological and social concerns.
Select the correct answer using the code given below:
With reference to two non-conventional energy sources called ‘coalbed methane’ and ‘shale gas’, consider the following ‘statements:
(1) Coalbed methane is the pure methane gas extracted from coal seams, while shale gas is a mixture of propane and butane only that can be extracted from fine-grained sedimentary rocks.
(2) In India abundant coalbed methane sources exist, but so far no shale gas sources have been found.
Which of the statements given above is/are correct?
The relation between focal length 'f'‚ object distance 'u' and image distance 'v' in the case of reflection of light by a spherical mirror is given by_______.
