Green EnergyEnergy that fits in with the ecosystem

Do you think that hydroelectric energy is a reliable energy resource for a safe and clean environment?

Ok! Hi. I have a research paper for English, and my topic is hydroelectric energy. I am having a hard time deciding whether or no hydroelectric energy is a reliable enregy resource for a safe and clean environment. To check it up, go t Wikipedia.I need help!
Thx

No. In the state of California, our new policy (AB32) states that a big hydroelectric is no longer considered a renewable resource. Small dams are still considered renewable, but it is in our last of renewable priority. This is because of:

(1) Fish, like salmon, can’t travel upstream to mate
(2) Culture, some indian tribes are against moving a whole river!
(3) Towns, moving a river’s path can affect the economy and well-being of the towns that use the river
(4) Chances of it breaking, causes devastating effects (like China and their floods every 3 years kills millions of people)
(5) Damage to land
(6) methane emissions from rotting vegetation that becomes submerged
(7) Eventual silting
