Can hydroelectric cause pollution

Answer 1

Hydroelectric energy offers a number of advantages for people who use it, the environment, and electricity suppliers. Read on to learn more about the advantages of hydroelectric power: 1. Using this type of energy to generate electricity is not dependent upon the price of uranium, oil, or other types of fuel. This makes electricity costs lower and more stable, one of its most significant advantages.

2. The pollution created by hydroelectric energy generation is quite minimal. There is some pollution involved in initially constructing the power stations, but this is true of all power plants. It also does not produce radioactive waste or involve the environmental impact of fuel being transported to it.

3. It doesn't require many employees to run a hydroelectric station. According to wikipedia.org, most plants of this type are largely automated. This is another one of the advantages which help keep the cost of hydroelectricity low.

4. Hydroelectric power stations can be set up in almost any size, depending upon the river or stream used to operate them; big enough to power a single home, factory, small town, or large city.

5. Another of its advantages is that hydroelectric is a renewable form of energy, like wind and solar; it does not rely upon finite resources like natural gas or coal to generate power.

6. Hydroelectric stations can operate for many years after they are built. Wikipedia.org states that a number of operational hydro stations were constructed fifty to one-hundred years ago; in contrast to this, IAEA.org indicates that the "design life" of nuclear power plants is generally thirty to forty years.

7. Small hydro electricity generation systems sometimes offer more economic advantages for home owners than solar power, and tend to last longer than solar panels do.

8. Hydroelectricity can emit just as many greenhouse gasses from plant decay down the river, as conventional methods of getting electricity.

Answer 2

Hydroelectric power is one of our honestly greenest forms of energy. With as little as 80,000 hydroplants we could supply the world energy needs for today.

The downside of this form of energy is the destruction of natural paths of water flow, thus causing issues with fish migratory paths. The destruction of land upstream of the dam and the lack of water downstream of the dam.

Most of these issues can be managed.

Answer 3

They destroy the feeding grounds and habitats by flooding the area behind it. The fish can get caught in the turbines and get trapped or killed. Many fish can't go upriver to spawn (Salmon) (I think that they should only build dams in rivers that cannot support the fish life or have the dams away from the ocean so the salmon can get to the spawning grounds)

Answer 4

Briefly, no. Nothing in the actual generation of hydroelectricity causes pollution.

There is some research that suggests that vegetation collects and rots in the deep water above a hydroelectric dam, and this produces methane, a greenhouse gas.

Answer 5

yes. but sometimes in some ways it has negative effects too in the environment...
