Q51. Which renewable energy source does hydropower most closely resemble in terms of reliability and consistency?
a) Solar
b) Wind
c) Biomass
d) Geothermal
Show Answer
Correct Answer: d) Geothermal
Explanation: Geothermal energy, like hydropower, provides a reliable and consistent source of electricity generation. Both harness natural processes (heat from the Earth’s core and flowing water) to produce electricity.
Q52. Which factor is essential for the economic feasibility of a small-scale hydropower project?
a) High initial investment
b) Access to large water bodies
c) Proximity to urban areas
d) Steady water flow
Show Answer
Correct Answer: d) Steady water flow
Explanation: Small-scale hydropower projects require a steady and reliable water flow to ensure continuous electricity generation. This factor is essential for their economic feasibility and long-term viability.
Q53. In which region are micro hydropower systems most commonly implemented?
a) Urban areas
b) Coastal regions
c) Mountainous areas
d) Desert regions
Show Answer
Correct Answer: c) Mountainous areas
Explanation: Micro hydropower systems are often implemented in mountainous regions with abundant water resources and natural elevation differences, making them suitable for small-scale hydropower generation.
Q54. Which renewable energy source is often used in conjunction with hydropower for electricity generation?
a) Solar
b) Biomass
c) Wind
d) Geothermal
Show Answer
Correct Answer: c) Wind
Explanation: Wind energy is frequently used in conjunction with hydropower for electricity generation to diversify energy sources and enhance reliability, especially in regions with variable weather conditions.
Q55. What is the primary advantage of hydropower compared to fossil fuel-based power plants?
a) Lower construction costs
b) Lower maintenance costs
c) Reduced environmental impact
d) Greater energy efficiency
Show Answer
Correct Answer: c) Reduced environmental impact
Explanation: Hydropower has a significantly lower environmental impact compared to fossil fuel-based power plants, as it produces minimal greenhouse gas emissions and does not require the burning of fossil fuels.
