What's So Special About Hydropower / Hydroelectricity?



What is hydroelectricity? Hydroelectricity is electricity produced by hydropower. Hydropower is a very broad term; it can refer to using water for irrigation, milling, and even textiles. That is why hydroelectricity is the proper term when referring to the renewable energy resource, which we are.

Hydroelectricity is the world’s leading source of renewable energy, supplying 19% of the world’s electricity, and accounting for 63% of the total renewable energy electricity generated. Large hydroelectric and small hydroelectric are the common names for the two types of hydroelectric installations. As you probably could have guessed, small hydro is “the application of hydroelectric power on a commercial scale serving a small community or medium sized industry.” Meanwhile, large hydro is used on a large scale.

So what’s so special about hydroelectricity? The fact that it’s already being used. As mentioned previously, hydroelectricity provides 19% of the world’s energy. Commercial industry can already expand off of hydro; it’s low tech, it’s been in use for over a hundred years, and it works inexpensively.

Does hydroelectricity have any harmful side effects? Let’s see what Wikipedia says:

Hydroelectric projects can be disruptive to surrounding aquatic ecosystems. For instance, studies have shown that dams along the Atlantic and Pacific coasts of North America have reduced salmon populations by preventing access to spawning grounds upstream, even though most dams in salmon habitat have fish ladders installed.
As important as salmon is, this small disadvantage should not be a reason to not use hydro.
If hydroelectricity is expanded upon and used with other technologies, hydroelectricity could become even greater than it already is.

thanks for the help with this.
we're doing a science project.
well uh. yeah thanks.

OMG. same here.
i have to write a science essay on whether or not I agree with the statement 'hydroelectricity is the most useful and efficient source of renewable energy'...
anyway um. i sited you in my bibliography in MLA format.
yea. just so you know.

Hi,We are a small company in WA. We are thinking for small hydro installation. Is there any subsidy available simillar to solar power? Green Ebooks Directory

Bill Gates and Steve Jobs have changed Computer history completely. But the interesting part is who is known as father of computers- Charles Baggage did not know that he would make an important place in history with his invention. Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Simple computers are small enough to fit into mobile device, and mobile computer can be powered by small batteries. Personal computers in their various forms are icon of the Information Age and are what most people think of as "computers". It was a great invention of world history.

It is really exciting to know that hydroelectricity provides 19% of the world’s electricity. Hydroelectricity energy is the greatest renewable resource that we have today. It is environment friendly also. Great post!
