Micro-hydel projects are suitable for decentralized power in hilly areas. They are small-scale hydroelectric power plants that use the energy of flowing water to generate electricity. Micro-hydel projects are typically located in remote areas where there is no access to the electrical grid. They can be used to provide power to small villages, schools, and hospitals. Micro-hydel projects are also a sustainable source of energy, as they do not produce greenhouse gases.
Option a is incorrect because micro-hydel projects are not suitable for large-scale power generation. They are too small to generate enough electricity to meet the needs of large cities or towns.
Option b is correct because micro-hydel projects are suitable for decentralized power in hilly areas. They can be used to provide power to small villages, schools, and hospitals in remote areas.
Option c is incorrect because micro-hydel projects are not suitable for irrigation in plains. They are too small to irrigate large areas of land.
Option d is incorrect because micro-hydel projects are not suitable for industrial usage. They are too small to meet the needs of large industries.
