  2. Why Hydroelectric Energy is Fantastic Hydro means water, and electric means energy, so it’s energy from water! :D If you didn’t know, water is everywhere, it covers two thirds of the Earth! So basically using any source of water we can make energy (so long as the water is flowing of course) Take Clinton for example: the Red Mill used the water from the river to produce energy back in the olden days

  3. How Do We Harness the Energy of Agua? Not only do mills utilize water for energy, but dams do as well Dams are a nifty little invention that block off rivers and choke the wildlife for our own benefit! The entire city of Las Vegas could not have been created without the use of dams to divert water from the Colorado River to the city The Hoover Dam is one of the most famous dams in the world, and it’s a monument to the power of rivers. The dam sends energy to cities miles away from it (like Las Vegas) and many other areas

  4. Generating Methods • Dams • Mills • Pumped Storage Schemes • Run-of-the-River Stations • Tides/Ocean • Underground Power Stations

  5. Why YOU Want to Use Hydroelectric Energy Fossil Fuels emit tons of pollution, hydroelectric energy doesn’t do that at all! It’s completely fossil fuel free Hydroelectric energy producers (mills) require very little maintenance. Anything that does break is very easy to replace

  6. Even More Pros! • It produces moderate to high net energy • It has an 80% efficiency rate, no energy is wasted • It has large untapped potential • Long life span • Provides Flood Control • Provides water for year round irrigation of cropland • Reservoirs are lot of fun! Who doesn’t like fishing?

  7. The Very Few (and Harmless) Cons • Dams can be expensive to build • Flooding can damage the land • Biomass decay emits CO2 • Converts the land habitat to lake habitat • They run the risk of collapsing • Decreases the fish harvest below dam • Decreases the flow of silt • The decomposing biomass and silt flow are the only major forms of pollution

  8. How Do You Use this Energy? • It’s simple, all you need is a flowing water source and a workforce to make the dam or mill • The best location would be somewhere that has hills so the water can flow down and a large open area for the resulting reservoir • In our area, as of April 30th 2009 the community has been considering putting hydroelectric dams in both the Spruce Run Reservoirs and the Round Valley Reservoir, however it is still not available in NJ

  9. Costs • The price of using hydroelectric energy is 11.36 cents per kilowatt hour • Building a hydroelectric dam itself costs about 300 million dollars • So for one day you can expect about 3 dollars per house, and in a year it would cost about $1095 • For the entire state one year would cost an upwards of $100,000

  10. How Do Dams Help You? • The water turns turbines inside of the dam, which turns a giant magnet in copper wire which creates an electric charge, thereby creating energy • That energy is then sent to houses • Also dams create a roadway to be used, the Hoover Dam is a giant road which covers the entire gap and is accessible to cars

  11. Transportation • Hydroelectric Cars: harness hydrogen and electricity to power its engine; fuel cells combine hydrogen and oxygen to produce electricity; efficiency is the same as gasoline-powered cars, yet they do not emit greenhouse gases • Hydroelectric Trains: China’s Three Gorge’s Dam is the world’s largest hydroelectric project and fastest train; can reach a speed of 220 mph

  12. What Is Tidal Power? • One of the many forms of hydroelectric power • It converts the energy of oceans tides into electricity and other useful forms of power • Tides are more predictable than wind or solar energy • Recent technological developments and improvements indicate that the total availability of tidal power may be much higher than previously assumed, and that economic and environmental costs may be brought down to competitive levels

  13. How Does Tidal Power Work? • A tidal barrage or dam is created at the mouth of a river or other choke point that connects to the ocean • In flood tidal power generation below the water level there are opening in this barrage that have turbines in them • These turbines are powered when the tide goes in or the water level rises.

  15. To Conclude • Hydroelectric energy would be easy to assimilate into our lives, the only hindrance would be the time it takes to build the dams. The easily available water makes this energy source very realistic • This is a very easy source of energy to use in conjunction with wind energy, building wind turbines and connecting them to the dam is a very easy and efficient process
