Wind
Advantage
Wind is free Does not cause
green house gas
Disadvantage
Does not produce same amount of electricity all time
Wind turbines are noisy

WaterAdvantage
Once dam is constructed, electricity can be produced constantly
Does not pollute the atmosphere
Disadvantage
Very expensiveNatural
environment destroyed

Conclusion Most of the energy are
expensive. This is the reason why people didn’t start using these energy even though they help us save the Earth from Global warming.
