Hydroelectric Power

Hydroelectricity is electricity produced from dams where water released from the reservoir flows through a turbine, which in turn activates a generator that produces electricity. In 2015, hydropower generated 16.6% of the world's total electricity and 70% of all renewable electricity. Arizona has several hydroelectric dams, mostlylocated along the Colorado River.
