Hydroelectric Energy is also one of the most biggest renewable energy worldwide. Hydroelectric Energy represents 17% of all electricity production. Hydroelectric energy collects energy from running water without reducing its quantities. Interestingly, hydroelectric energy helps fight climate changes. The Hydroelectric life cycle produces only very small amount of greenhouse gasses. Furthermore, Hydroelectricity also improves the air we breathe. Hydroelectricity does nothing to pollute the air and does not generate toxic too.
On the other hand, Hydroelectricity is perfect. However, it has some significant changes like it can change the water quality, it destroys fish habitat and costs a lot to build one. We can change this situation by having a wider space to fish to go down the river and put a water purification on the dam.
