What is keeping hydroelectricity from widespread use?
For hydroelectricity to work a large, fast flowing body of water
or river is needed and it has to be controlled by a dam and a large
reservoir, those would need to be man made. Things that keep
hydroelectricity from widespread use is the cost of building, the
time to build, the environmental impacts such as possible flooding
of entire valleys or towns and fishing impacts and the cost to
prevent siltation. Building of hydroelectricity plants has caused
many arguments and debates, so many officials do not want to deal
with the issue.
