2. HYDROELECTRICITY - is electricity produced from hydropower.
HOW IT WORKS?
Hydropower plants capture the energy of falling water to
generate electricity. A turbine converts the kinetic
energy of falling water into mechanical energy. Then a
generator converts the mechanical energy from the
turbine into electrical energy.

3. HOW IT WORKS?

4. HISTORY
The history of hydropower started over 2000 years ago, when
water wheels were being used by the ancient Greeks to grind grain.
It was not until the Middle Ages that the technology was spread to
Europe.
Hydroelectric power was also important during the industrial
revolution at the beginning of the 1800’s and provided mechanical
power for textile and machine industries.
The most important year in hydropower history was in 1831 when
the first electric generator was invented by Michael Faraday. This
laid the foundation for us to learn how to generate electricity with
hydropower almost half a century later, in 1878.

5. HISTORY
The first hydroelectric power plant, located in Appleton,
Wisconsin, began to generate electricity already in 1882. The
power output was at about 12.5 kW. 7 years later, in 1889, the
total number of hydroelectric power plant solely in the US had
reached 200.
In the 19th century, these power plants got an increased amount
of commercial attention and was built rapidly in suitable areas all
over the world. 1936 marks an important year – the largest
hydroelectric power plant, the Hoover Dam, was opened and
generated 1345 MW (installed capacity later increased 2080MW)
from the flowing water in the Colorado River.

6. HISTORY
During the first half of the 1900’s hydropower became the world’s
most important source of electricity.
In 2008, Three Gorges Dam in China was built. This is the largest
power plant at current date, generating 22.500 MW, adding to
China’s installed hydroelectric capacity of 196.79 GW (2009).
