Question:
How is it saving the enviorment by reducing electricity if your power comes from a hydro dam?
Answer:
Answer:
It's a good idea due to the following
Advantages:
1. Fuel is not burned-less pollution
2. Water to run the power plant is provided free by nature
3.Hydro power plays a major role in reducing greenhouse gas emissions
4.The technology is reliable and proven over time
5. It's renewable - rainfall renews the water in the reservoir, so the fuel is almost always there but rainfall dependent!!
Disadvantages:
1.High initial costs
2.People living in downstream areas have to be relocated which involves Huge capital again.
3.After all its rain dependent
Hydro electric power represents 19% of the total electricity production( world basis).
There is much potential for it due to availability of water resources in countries like Latin America,India,China.
But as a whole to conclude,hydro resources must be identified, and a detailed life cycle analysis must be made for pollution and cost statistics to generate electricity,compare it with the traditional ways.
Then one can opt a methodology that would be apt for a country.
