HYDROELECTRIC POWER
Map Skills
The United States is the third largest producer of hydroelectric power. Only
Canada and Brazil use more water for hydroelectricity. Together these three
countries make up 37 percent of the world’s hydroelectric power generation. This
map shows how states compare in their use of water for hydroelectric power.
Use the map above to answer the questions below.
1. Using a Key What three states use the most water for hydroelectric energy?
_______________________________________________________________
2. Analyzing Data Do the majority of states use more than or less than 100,000
million gallons of water for hydroelectric power per day?
_______________________________________________________________
3. Making Conclusions How much water per day does the state where you live
use for hydroelectric power?
_______________________________________________________________
4. Making Conclusions Based on what you have learned in this chapter, do you
consider it a good thing or a bad thing if a state uses a high amount of
hydroelectric power?

Solar cells supply energy to homes, space
stations, and common objects such as
calculators.
In developing countries, energy
consumption is minimal and electricity
networks are limited.
Solar cells produce only a small amount
of electricity; thus, acres of them would
be needed to supply energy for a small
city. Also, solar cells require extended
periods of sunlight.
