Hydroelectric Power Plant

Transcript: By: Abby Cross And Sadie Lawson Hydroelectric Power Plant The town of Oxford is in need of a new power plant. Oxford is a city with approximately 5,500 residents and sits in a valley, protecting it from harsh windy conditions and supplying it with comfortable weather year-round. Along the outskirts of the town is Jackson Lake Park. Several tourists visit the park throughout the year to enjoy its beautiful scenery, rich wildlife, and to participate in outdoor recreational activities like fishing, hiking, swimming, boating, and camping. The lake is fairly shallow, so visitors enjoy the ability to wade in the lake with ease. The Jackson River runs through town and empties into Jackson Lake. Although there are only a few residents that live along the lake, the river cuts through the heart of the city, passing through the business district and residential areas. Despite the river location and limited depth, Oxford has only had two major floods in the past 100 years. However, both floods caused severe water damage to the local residents and businesses. As the city considers its options for building a new power plant, several residents have voiced their concerns. Residents are looking for an energy source that is environmentally friendly, creates little waste, is renewable, and affordable. In addition, residents want to preserve the natural habitat of Jackson Park. Scenario Power Plant Selection Power Plant Selection What energy source should your power plant utilize? Hydroelectric resource What resources (energy sources) are available for your power plant A river Work How does the energy source/power plant work – how will it generate the power needed to provide electricity to your residents?

In the 1870s, the Pelton wheels was introduced The Pelton Water Wheel was invented in the mid 1870s, by Lester Allan Pelton. It was This used a slightly different method than the previous water wheel, using the momentum of moving water to turn the wheel, instead of its dead weight. Lester Allan Pelton was an American Inventor that made a huge contribution to the development of hydroelectricity (and hydropower in general) by his inventions, the Pelton Water Wheel. The Intial Discovery /reaction The first Hydroelectric power station In 1882, September 30 to be exact, the first hydroelectric power station started running. It was situated on the Fox River in Appleton, Wisconsin. This whole idea of this came from a man called H.J. Rogers, who was inspired by the power plants of Thomas Edison, a very famous inventor of the times. These plants were steam-driven. So Rogers decided to get a group of people to work on the project of making the first hydroelectric power plant. In doing so he formed his company - Appleton Edison Electric Light Company. This was the dawn of hydroelectric power plants, which many operate today. Unfortunately, the Vulcan Street plant was destroyed in a fire in 1891, but a complete replica was later built on South Oneida Street. How the world would look like if that discovery had never been made? The modern hydro power turbine began mid 1700s when a French engineer, Bernard Forest De Belidor who designed an architectural plan of the Hydraulique. References In 1880, the dynamo generator was driven by the water as it was used to provide electricity during the processive reaction. In 1881, the generator connected to a turbine with a flour mill that would provide street lighting. This was used in the Niagara Falls, New york The discovery of hydroelectricity has impacted many countries such as the United States of America, Canada and China. They use the hydroelectricity plants to power electricity cables for towns, suburbs and hopefully it will eventually be used in countries as they are seeing the benefits of it. If hydroelectricity was not discovered 100’s and 1000’s years ago by ancient Greeks and Egyptians the world would be lacking in another renewable resource and we would be using up more of the earths fossil fuels that take 100’s of years to create. In ancient greece the water wheels were used for grinding wheat into flour more than 2,000 years ago. The modern hydro power turbine began mid 1700s when a French engineer, Bernard Forest De Belidor who designed an architectural plan of the Hydraulique. The demand for the Industrial Revolution influenced the thriving development of the electrical generator that can generate electricity through water. As technology developed so did the lifestyle of many people who manually did work on the fields and working with water sources. The development of the hydroelectric power plant has revolutionised the world and has changed the daily lives of many who worked by hand. The hydroelectric power plant can now power more than thousands of homes with electricity. In 1878, the first hydroelectric power developed at Northumberland, England by William George Armstrong Reaction: An electric spark in the air is caused between two conductors in the the blades of the generator create friction to produce electricity. The next steps which brought that discovery/reaction into our day and age

Transcript: The waste produced by nuclear reactors needs to be disposed off at a safe place since they are extremely hazardous and can leak radiations if not stored properly. Such kind of waste emits radiations from tens to hundreds of years. The mixed wastes cause hazardous chemical reactions and leads to dangerous complications. These wastes can be used to make nuclear weapons. The Hydro Power Plant is near Fredericksburg, Virginia. The dam is on the Rapidan river which is a fast flowing river. Virginia is a humid and subtropical place so it doesn't have many droughts. It has a good amount of rainfall each year. Since Virginia has a large trout population, so you can put a fish ladder on the dam to let fish pass on through without getting hurt. Has relatively low maintenance and operating costs. By: Hydro Rapidan Inc. The buildup of water in the lake means that energy can be stored until needed, when the water is released to produce electricity. Nuclear energy uses uranium which is a rare resource and not found in many countries. Since it is rare, Nuclear power is nonrenewable. Small radiation leaks can cause devastating effects. Some of the symptoms include nausea vomiting, diarrhea and fatigue. People who work at nuclear power plants and live near those areas are at high risk of facing nuclear radiations, if it happens. In the U.S. Hydro power produces enough electricity to serve the needs of 28 million people Nuclear power plants are very expensive which costs around billions of dollars. They also take 5-10 years to build. Nuclear energy has given us the power to produce more weapons than to produce things that can make the world a better place to live in. Mechanics of Hydro Power Plant They can easily be upgraded to incorporate the latest and most efficient technologies. The water flows through the turbine which makes the turbine start to spin. Then it turns a metal shaft in the electric generator which is the motor that produces electricity. The energy from the moving water turns into mechanical energy. The power lines are connected to the generator that carry electricity to homes. Not only does building a dam contribute produce electricity, it can also stop flooding, helps navigating the flow of the river, supply water for agriculture,industries, and households. It cuts down the fast current of the river making it a place to do activities like swimming, boating, etc. Reports say that radioactive wastes take almost 100,000 years to get back to the original form. Nuclear Power Plants It is very cost effective and is not very expensive. Hydro power does not "use" water, all of the water is returned to its source of origin. Hydro power produces about 97% of renewable energy. It is very clean and it prevents the burning of 22 billion gallons of oil and 120 million tons of coal each year. Hydroelectric Power Plant Hydroelectric Power Location of Hydro Power Plant Hydro dams are known to last around 100 years which make the investment worth it.

Transcript: Made By: Bianca V. González Hydroelectric Power Plant Hydroelectric Power Plant A hydroelectric power plant is a power plant that makes energy out of waters movement. What is a Hydroelectric Power Plant? What is a Hydroelectric Power Plant? Hoover Dam Hoover Dam How is energy transformed or transferred? Potential Energy Kinetic Energy Mechanical Energy Electric Energy How is energy transformed or transferred? It starts off by potential energy from a river or dam changing to kinetic energy as water flows downhill, then kinetic energy converts to mechanical energy and it moves the turbine making the generator transform mechanical energy to electrical energy. Explanation Explanation Picture of a hydroelectrical power plant Picture of a hydroelectrical power plant Does not pollute the air or water Hydroelectric power plants are relatively inexpensive to operate. Advantages Advantages Dams damage wildlife habitats Dams can affect water quality and reduce the flow of waterdownstream Droughts can affect hydroelectric power plants Disadvantages Disadvantages Is one of the oldest power sources on the planet It was used by farmers as far back as ancient Greece. Niagara Falls was the site of the country’s first hydroelectric generating facility (built in 1881). The oldest hydroelectric plant is Cragside in Rothbury, England The largest hydroelectric plant is La Grande in Quebec, Canada Fun Facts Fun Facts In the United States over half of the electricity generated from hydroelectric power is concentrated in Washington, Oregon, and California. The largest site in the U.S. is Grand Coulee in Washington which has 33 generators. Hydro generators can start producing electricity within 90 seconds and this makes them suitable for backup generators in case of failures. There are more than 100 hydroelectric power plants in Australia which produce the majority of the renewable energy produced in the country. Cont. Cont. Conclusion: Conclusion: Imagine living without power. For example Hoover Dam gives power to Nevada, Arizona, and California. Meaning you can power a huge place with only water. This is mind blowing that you could live a great life with not that much polution. Well it obviously has it's ups and downs because it can harm wild life and harm the quality of water. Beside the point if we didn't have water we couldn't generate power, or live at all. Hoover Dam 2009 Hoover Dam 2009 Thx For Watching Thx For Watching
