The use of micro-hydropower systems is encouraged in Arunachal Pradesh for:

The correct answer is: d) All of the above

Micro-hydropower systems are encouraged in Arunachal Pradesh for the following reasons:

• Decentralized power generation: Micro-hydropower systems can be installed in remote areas where there is no access to the national grid. This allows for the generation of electricity close to where it is needed, which can help to reduce transmission losses.
• Rural electrification: Micro-hydropower systems can be used to provide electricity to rural areas that are not connected to the national grid. This can help to improve the quality of life in these areas by providing access to basic services such as lighting, refrigeration, and telecommunications.
• Minimal environmental impact: Micro-hydropower systems have a relatively low environmental impact compared to other forms of power generation, such as coal-fired power plants. This is because they do not produce air pollution or greenhouse gases.

In addition to these reasons, micro-hydropower systems can also help to improve the local economy by providing jobs and income opportunities. They can also help to reduce poverty by providing access to electricity, which can help people to start businesses and improve their livelihoods.
