Hydroelectricity Joseph Franco and Chris Barreto Yeah, Boy!!! …Yea.. I’m not going to say anything during this slideshow.

What is this you speak of… Hydroelectricity is a renewable energy source involving hydropower, or the product of the power of flowing water caused by gravity.Hydroelectricity is a renewable energy source involving hydropower, or the product of the power of flowing water caused by gravity. Ex. DamsEx. Dams WOOOAH! That’s A LOT of water!!! !

A more primitive example is… The Water MillThe Water Mill Ancient Mesopotamians used this as a tool for irrigation.Ancient Mesopotamians used this as a tool for irrigation. In Greco-Roman culture, this was used to process certain ingredients such as flour, as well as a tool in textiles.In Greco-Roman culture, this was used to process certain ingredients such as flour, as well as a tool in textiles.

More in depth… Energy is gathered by fast moving water. This can be done if a river moves quickly, like the Columbian River, or at the edge of Niagra Falls. But if the river currents aren’t fast enough to push the turbines, dams are created. Dams gather water until the demand for water grows. In the meantime, these dams are used in other ways, like for boating and fishing. Hydroelectric energy and coal fueled energy work in a similar fashion…Energy is gathered by fast moving water.

Advantages The process of fueling hydroelectric plants is cheaper than the average plant. The operators do not have to concern themselves to fuels such as oil, natural gas, or coal. These types of plants last for a long time due to their lack of gases and other harmful material which, in time, could damage the turbine or engine.The process of fueling hydroelectric plants is cheaper than the average plant.

Advantages 2 This type of energy source leaves little to no emissions to the environment, so it’s clean!This type of energy source leaves little to no emissions to the environment, so it’s clean!

Disadvantages Dam failures- if a dam fails, it could be potentially dangerous. The resulting flood would leave thousands, if not millions, homeless. Large dams are often targets of terrorism, sabotage and are often exploited during wartime.Dam failures- if a dam fails, it could be potentially dangerous.

Flow shortages- If a river of stream holds less water, or if a river dries up, the area relying on that power may suffer shortages.Flow shortages- If a river of stream holds less water, or if a river dries up, the area relying on that power may suffer shortages.

Disadvantages 2 Relocation- Sometimes, populations must be relocated to make room for a hydroelectric plant. Owners are often given little or no compensation for the cultural or ancestral value.Relocation- Sometimes, populations must be relocated to make room for a hydroelectric plant.

How does it work? The reservoir water body goes into a stream. The running water activates the turbine and turns on the generator. The generator is hooked up to the transmission lines, where electric currents distribute and go to society.The reservoir water body goes into a stream.

Extra Info -Some countries, like Canada, China and Brazil, produce a large amount of energy from Hydroelectric plants.-Some countries, like Canada, China and Brazil, produce a large amount of energy from Hydroelectric plants. -Places in Africa and South East Asia produce less energy because of their low funds.-Places in Africa and South East Asia produce less energy because of their low funds.

Remember, kids… Promote hydroelectricity in your county today!
