FC: Hydroelectric Energy | By Lauren Hecht

1: Hydroelectricity is an eco-friendly and reliable alternate energy source, and should be the first power source your corporation turns to if needed.

2: When electricity is created by using hydropower, it is known as hydroelectricity.

3: Most hydroelectricity is created by using dams. When water flows through dams, it turns turbines that turn generators, which produce electricity. Overall, it's very simple, and a much more efficient way of creating a source of energy.

5: As you can see in the diagram, water is held in the headpond at the top of the dam. Then it is taken through the intake and flows down the penstock, before entering to turbine. The water flow causes the turbine to spin, which spins the generator, creating electricity. The energy is then transported from the transformer onto the transmission lines, to give electricity to local powerlines. The water in the turbine then flows down the draft tube and into the tailrace as more water flows in, starting the process over again.

6: Disadvantages of Hydroelectricity Usage | Dams take up a large amount of space, and can cost a lot of money to create. Dams can damage nature sites, such as parts of forests and meadows. They can sometimes damage local ecosystems by driving its habitants out.

7: Also, dam usage is very dependent on the weather. If there were an extended drought, there would be a low water level, and a smaller current, which means less water would make it to the dams. With less water comes less energy created. This would only occur during a very, very long drought, though.

8: There are many advantages to hydroelectricity usage. Although creating dams can cost a lot of money, it would be worth it once the dam begins creating energy. Dams are very durable, and can last for years. | Advantages of Hydroelectricity Usage

9: The Hoover Dam has proven how strong and efficient dams can be. The Hoover Dam has been around for 76 years, and is still producing energy, 4.2 billion kilowatts a year, in fact. | Once dams are built, all they need is a maintenance and engineering crew to keep things running smoothly. Other than that, dams that we build would be able to function for many years to come.

10: Dams are surprisingly simple creations that do not pollute the air and water around us. Hydroelectricity is one of the only alternate energy sources that does not emit greenhouse gases. | As for the wildlife, although building dams can run animals out of nearby forests and meadows, dams can also create many ponds where new ecosystems can flourish.

11: Also, dams won't disrupt a fish's yearly journey upstream, with the creation of fish ladders, which would be installed into the dams. | Fish ladders are a series of wide-set steps that slowly slant upward. Fish are able to jump from one step to the other until they reach the top of the dam, where they can continue their migration.

12: With the information I've provided, I hope that hydroelectricity is your clear choice. It is eco-friendly and reliable. The cost to build the dam itself may seem high, but after it is constructed it will be useful for years and years, and will build new eco-systems while providing societies with energy. It will do all this without damaging its surroundings with harmful pollution.
