प्रश्न
Hydroelectricity is considered a good energy option for the future. Why?
उत्तर
Hydropower is fueled by water, so it’s a clean fuel source, meaning it won’t pollute the air like power plants that bum fossil fuels, such as coal or natural gas.
Hydroelectric power is a domestic source of energy, allowing each state to produce its own energy without being reliant on international fuel sources.
The energy generated through hydropower relies on the water cycle, which is driven by the sun, making it a renewable power source, making it a more reliable and affordable source than fossil fuels that are rapidly being depleted.
