What is one of the main disadvantages of hydroelectric power?

Perhaps the largest disadvantage of hydroelectric energy is the impact it can have on the environment. … To build a dam, new roads and power lines must be installed that disrupt the environment. Dams also often form reservoirs that flood large areas and displace natural habitats.

What is a disadvantage to hydroelectricity quizlet?

Compared to among others fossil fuels and nuclear energy, hydroelectricity is much safer. Disadvantages. Dams cause environmental problems. Can cost a lot long-term. Relies on water – potentially could lose source.

Which characteristic is a disadvantage of hydroelectric plant?

What is an advantage of hydroelectric power quizlet?

Hydropower is fueled by water, so it’s a clean fuel source, meaning it won’t pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Hydroelectric power is a domestic source of energy, allowing each state to produce their own energy without being reliant on international fuel sources.

How do run of the river hydroelectric systems differ from large dams quizlet?

They do not differ; they work the same way. They don’t block all of the water flowing down a channel and only direct some of it through a turbine. They are built close to shorelines whereas giant dams can only be built farther inland. They literally “run” the river and take over the entire ecosystem.
