Which of the following power plants is least reliable:
- Coal
- Hydro
- Wind
- Nuclear
Correct answer: 3. Wind
Explanation: While nuclear power plant is the most certain source for power generation. A wind farm is the least reliable source for generating power
The wind fluctuations can be a serious problem resulting in reduced efficiency of turbines. Wind energy requires an adequate supply of wind energy. Since wind is not constant at all places all the time, thus making wind energy the least reliable source.
