The correct answer is: b) Micro and mini-hydropower.
Meghalaya has significant potential for micro and mini-hydropower because of its abundant rainfall and steep terrain. Micro and mini-hydropower plants are small-scale hydroelectric power plants that can be used to generate electricity in remote areas. They are often more cost-effective and environmentally friendly than large-scale hydropower plants.
Large-scale hydropower plants are more expensive to build and operate than micro and mini-hydropower plants. They also have a greater impact on the environment, as they require the construction of dams and reservoirs.
Solar power is another option for generating electricity in Meghalaya, but it is not as well-suited to the state’s climate as micro and mini-hydropower. Solar panels are less efficient in cloudy or rainy weather, which is common in Meghalaya.
Wind power is also a possibility, but there are not many windy areas in Meghalaya. Wind turbines are also expensive to build and operate.
In conclusion, Meghalaya has significant potential for micro and mini-hydropower. These plants are more cost-effective and environmentally friendly than large-scale hydropower plants, and they are better suited to the state’s climate.
