What is hydropower - Hydropower definition
Hydropower
is renewable energy source with very long tradition, used in many countries all
over the world.
Hydropower
is often referred to as water power. The simplest definition of hydropower
would be the power that derives from the force of energy of the moving water.
Hydropower
is widely used to generate electricity, in fact hydropower currently satisfies
approximately 8% of U.S.
electricity demand.
Hydropower
doesn't only refer to large hydroelectric power plants, it also includes small
and micro hydro systems.
Large
hydroelectric power plants can have negative environmental impact while small
and micro hydro systems have very low environmental impact.
The United States
currently has more than 2,000 hydroelectric power plants.
Hydropower
currently accounts for approximately 50% of U.S. total renewable electricity
generation.
The largest
hydroelectric power plant in the United States
is the 6,800-megawatt Grand Coulee power station on the Columbia River in Washington State. The largest hydroelectric power
plant in the world is China's
Three Gorges Dam.
The first U.S. hydroelectric power plant was opened on the
Fox River near Appleton, Wisconsin, on September 30, 1882.
Not all
dams in United States
were built to generate electricity, they were also designed for irrigation and
flood prevention.
Large
hydroelectric power plants are connected with significant construction costs.
This means that there is a long waiting time for large hydroelectric power
plants to return investment and start bringing profits.
Hydropower
is clean, renewable energy source that doesn't contribute to climate change and
global warming like burning of the fossil fuels does.
Hydropower
is one of the most reliable renewable energy sources with very good efficiency.
Hydroelectric
power plants last for very long time.
Hydropower
does not produce waste like this is the case with some other energy sources
(nuclear energy).
Large dams
can sometimes lead to disruption of the natural flow of rivers, stream levels,
flow patterns, temperature of the water, all of which can hurt river
ecosystems.
At the
beginning of 2012 global hydropower capacity accounted for approximately 740
GW.
Much of
global hydropower potential still remains untapped so hydropower has great
potential for many countries all over the world.
Around
seven percent of U.S.
total power is currently being produced by hydroelectric plants.
Hydroelectric
power plants today exist in 34 U.S.
states.
Harnessing
more hydropower would improve our energy independence and energy security by
decreasing the need for expensive foreign fuel import.
U.S. is third largest hydropower
producer in the world, behind China
and Canada.
New
hydropower projects could give boost to our economy by providing many new
construction jobs.
