Q1:

Consider the following statements regarding Surface Hydrokinetic Turbine (SHKT) technology:

1.   SHKT generates electricity from flowing water without the need for dams.

2.   It provides round-the-clock energy in areas with limited grid access.

3.   SHKT has high installation costs but minimal environmental impact.

Which of the above statements is/are correct?

A: 1 and 2 only

B: 2 and 3 only

C: 1 and 3 only

D: 1, 2, and 3

Show

Answer: A

Explanation:

Statement 1 is correct: SHKT uses the kinetic energy of flowing water without requiring dams, and it provides electricity at ₹2-3 per unit.

Statement 2 is correct: It offers renewable energy in off-grid areas and can be integrated into existing infrastructure like canals.

Statement 3 is incorrect: SHKT has low installation costs, not high, and it has minimal environmental disruption, making it environmentally favorable for India’s renewable energy goals.
