Other Beneits of Water Power
Water power is more than just a clean source of electricity.
The different forms of water power have other helpful results.
When dams are built, they create large bodies of water. These
reservoirs and lakes have several uses. For example, water
from the reservoirs can be used for drinking and to grow crops.
Reservoirs provide a source of water when there are droughts.
Lakes created by dams
also provide opportunities
for outdoor activities.
Hoover Dam, on the
Colorado River between
Arizona and Nevada,
helped create Lake Mead.
The lake and land around
it attract many visitors.
They come to sail boats,
swim, ish, or just enjoy
the outdoors.
Ocean and tidal power
have several possible
beneits. The cold water
used in ocean thermal
energy conversion (OTEC)
can be used again after
it helps create electricity.
The water can be piped
Hoover Dam, a huge structure on the Colorado
River, created Lake Mead behind it.
