Question

Following are the sources of electricity generation in India. Arrange them in correct sequence on the basis
of total power generation capacity (higher to lower) :
(A) Nuclear
(B) Thermal
(C) New and renewable energy
(D) Hydro
Choose the correct answer from the options given below :

• A. (A), (B), (C), (D)
• B. (A), (C), (B), (D)
• C. (B), (C), (D), (A)
• D. (B), (D), (C), (A)

Answer 1

The Correct Option is D

To solve the problem of arranging the sources of electricity generation in India in the correct sequence from higher to lower based on total power generation capacity, we need to understand each source's contribution. India's primary sources are: 

1. Thermal: This includes coal, gas, and oil-based power, which are predominant due to their established infrastructure and resource availability. Thus, thermal power typically has the highest capacity in India.
2. Hydro: This is a renewable source with significant capacity, tapping into the country's many large rivers.
3. New and Renewable Energy: This includes wind, solar, and other renewable sources. While growing rapidly, it still generally falls behind thermal and hydro in terms of capacity.
4. Nuclear: This represents a smaller portion of India's power generation due to the limited number of facilities and high setup costs.

Based on the above analysis, the correct sequence from higher to lower capacity is Thermal, Hydro, New and Renewable Energy, and Nuclear.

Therefore, the correct answer is: (B), (D), (C), (A)

Answer 2

Thermal energy is the largest source of electricity generation, primarily derived from the burning of fossil fuels like coal, oil, and natural gas. It accounts for the majority of global energy production due to its well-established infrastructure and high energy output.

Following thermal energy, hydroelectric power is the next largest source of energy. It harnesses the power of flowing water, typically through dams, to generate electricity. Hydroelectric power is considered a renewable energy source and plays a significant role in providing clean, reliable electricity in many regions.

Renewable energy sources, such as wind, solar, and biomass, have been growing rapidly in recent years. These sources are increasingly seen as essential for transitioning to a more sustainable and environmentally friendly energy system, reducing dependence on fossil fuels and decreasing greenhouse gas emissions.

Nuclear energy is another significant source of electricity, providing a large amount of power with low carbon emissions. While nuclear power offers the advantage of generating substantial electricity without producing greenhouse gases, it also raises concerns about safety, radioactive waste management, and high costs.
