Hydroelectricity By Moriah Webb 8-S
HydroelectricityWater producing electricity. • Cons • Important Cons • #1 • #2 • #3 • Other Cons • What countries produce it? • How does it work?
Con #1 • Dams are expensive to build, and can take many years to build. • Ex: Mansfield Dam, Austin, Texas • Took five years to build • Cost $30,000,00o • Cost $15,000 to maintain each year
Con #2 • Fish cannot swim upstream for spawning, or go downstream without the chance they will be killed by the turbines.
Con #3 • Plant decay washed downstream clogs at major dams producing as many greenhouse gasses as more conventional methods of producing electricity.
Other Cons • Hydroelectric power production requires flooding of entire valleys and scenic areas. • Disrupts natural seasonal changes in the river, and ecosystems can be destroyed. • Stop flooding that help to clean out the silt in rivers, causing turbines to flood to clog.
Other Cons • Dams can break in a massive flash flood. • Flooding takes away scenic and agricultural areas • Can take away many animal homes and even take peoples homes away.
