Near Taupo
Why is it useful?
- Fuel is not burned so there is minimal pollution.
- Water to run the power plant is provided free by nature.
- It's renewable - rainfall renews the water in the reservoir, so the fuel is almost always there.
Disadvantages:
-Disrupts aquatic ecosystems-Hydropower plants are typically constructed across rivers, and this can interfere with aquatic life and result in their huge scale devastation. There is a huge probability that the fish or other river animals may find a way into the penstock and eventually into the turbines where they will be exterminated. Construction of dams in specific places can interfere with the mating patterns, seasons and breeding areas of the water animals.
-Construction needs a large area- To be able to construct a dam, install power production units, plus transformers, and tether them to the main grid requires a large piece of land. This may call for clearing of large chunks of forest to provide space for building the dam. Clearing of forest greatly impacts the natural ecosystems.
