There are many things to worry about when you are creating energy with hydroelectricity. Things like if the dam breaks or the sand can start to decrease the populations on the fish that would live there. Many more things can go wrong that can affect the community.
This type of energy costs a lot of money to deal with. This can also cause a lot of droughts in the town. Another thing is that it can change the water and its physical features. Around the world not many countries use this energy form. Hydroelectric energy releases a lot of methane and carbon dioxide.This happens because the plants and trees will start to decompose by another way without using oxygen, so this type of decomposition will release methane and carbon dioxide creating more and more pollution. This will lead to a large amount of pollution in the water harming the wildlife in and around the body of water. Also dams, which hold the water, are very expensive to build. The amount of energy that is created can depend on the amount of rainfall that is produced because in order for it to work there needs to be a lot of water. Once dams are not used anymore they can not be taken out or broken because it would cause serious flooding.
Hydroelectric energy can be a dangerous and scary energy to have, seeing as a dam could break and flood a whole city/town. So is having this energy really worth it?
