==__Describe this alternative resource. __ ==  Hydroelectricity is electricity generated by water. You get the electricity from

moving water. When the hydroelectricity

is finished with making electricity it has no waste. Hydroelectricity power

generators are used by power plants. To get

energy you must build a dam on a large river that has a large drop in elevation.

Hydroelectricity is another term for

power generated by water. Hydroelectricity power can help the climate. Water

has been one of our biggest resources

for a long time. Hydroelectricity is considered a clean and renewable resource. [|Here is a game!!]

== ** The hydroelectric process is first the gates open. Then the second step is the water goes under the dam. The water moves fast and spins the turbine and the turbine moves the generator. Then, the power from the generator goes to the power house. Then the the power goes to the cables. Then the last step is that it goes to our homes!!! **==

__Describe the advantages of using this resource instead of burning fossil fuels.__
** There are many advantages of using hydroelectricity. Here are some. The advantages of using this resource are that it is a clean, safe, non-polluting way to generate electricity and eliminates the cost of fuel. The generators or hydroelectricity power plants, are not affected by the costs of fuel such as oil, natural gas, and coal therefore we do not need to import fuel. Another advantage of this resource is that it is an inexhaustible resource. Diagram of Hydroelectricity Some more advantages are that once a dam is built, energy can be created or generated at a constant speed, if electricity is not needed at the time, then the sluice gates can be shut thus keeping the water in, so water can be saved for another time when the water is needed or when the demand is high. Hydroelectricity dams also last a very long time and are built to be around for many, many years, and the lake that forms behind the dam is usually used as a tourist attraction or as a resort. People enjoy tubing, relaxing, swimming, fishing, and other fun activities. ** [|**Click here for a game!!!**] 

__ Describe the disadvantages of using this resource. __
There aren't many disadvantages of using hydroelectricity. Here are a few. To start off, the dams which are built in order to produce the hydroelectricity can impact the mobility of fish. This is why fish ladders are often built while building hydroelectric dams. Another disadvantage of using hydroelectricity is that behind the dam, there are often floods. Also, the water supply behind the dam is usually very low. People that live on the bank or the edge of the reservoir are often at risk because of the flooding that might occur. As you can see, there are many more advantages of using hydroelectricity than there are disadvantages.

Describe how this energy relates to your everyday life.
Hydroelectricity relates to our everyday life because it gives us electricity that we use in our homes and businesses. The reason it relates to our everyday life, is if we didn’t have energy the businesses would have no electricity to use computers, printers, and other things that use electricity. Some of the use is not just at our homes and businesses,but it also gives people jobs, like of course building the dam, watching the generator to make sure it is working right, running the dam, and repairing it.  **__Here: a video, a diagram of a hydro power plant, a dam, and a business that runs a dam.__**
