This document discusses hydroelectricity and provides an overview of its history and production. It covers:
- The history of hydroelectric power dating back 2000 years to water wheels being used by Greeks, and its expansion in the late 1800s/early 1900s with the invention of hydraulic turbines.
- How hydroelectricity works by using the gravitational force of falling or flowing water to generate electricity through turbines. It is a renewable source that supplies around 20% of the world's electricity.
- Some advantages are its low costs and that it produces no direct waste, but disadvantages include interrupting river flows and harming ecosystems through dam building.

Conclusion
4. OUR Objectives
• We will be discuss about the source of
Hydroelectric energy
• History of hydroelectericity
• We will describe “how Hydroelectric energy is
produced?”
• We will show Hydroelectric energy as an very
useful acceptable source of energy
• We will discuss where is Hydroelectricity is
used
6. History of Hydroelectric Power
• Nearly 2000 years ago the Greeks used
water wheels to grind wheat into flour
• In the 1700's, hydropower was broadly used
for milling of lumber and grain and for
pumping irrigation water
• Appleton, Wisconsin became the first
operational hydroelectric generating station in
the United States, in 1882, producing 12.5
kilowatts (kW) of power
7. • The total electrical capacity generated was
equivalent to 250 lights
• Within the next 20 years roughly 300
hydroelectric plants were operational
around the world
• The invention of the hydraulic reaction
turbine created the sudden expansion of
hydropower
• 40% of the United States' electricity was
provided by hydroelectric power in the
early 1900's
16. Overshot Wheel
It was more efficient that
breast shot wheel. Some
mills using
These wheels still in
operation
In rural areas in from
1950’s till know

21. How useful is it?
• Moderate to high net useful energy yield
• fairly low operating and maintenance costs
• low pollution
• rarely shut down
• help control flooding
• supply a regulated flow of irrigation water to
lowlands below the dam
22. Compared to Others
• Has moderate to high net useful energy
• Solar energy and hydroelectric are the
highest producers of energy besides
nonrenewable resources
23. Drawbacks
• Flood vast areas
• destroys wildlife habitats
• uproots people
• keeps nutrients from being sent downstream
• decreases fish harvests below the dam
• keep fish from migrating upstream
• kills large numbers of fish
