1. Hydropower! Hayley Satterlund and Meredith Wolfe 1st Hour

2. Uses/Functions Generates electricity River transportation Irrigation Recreation Flood Control Most often used out of all renewable energy sources Powerplants must be located on a water source

6. Components Dam: Raises the water level of the river to create falling water Turbine: The force of falling water pushing against the turbine's blades causes the turbine to spin Generator: Connected to the turbine by shafts and possibly gears so when the turbine spins it causes the generator to spin also. Transmission lines: Conduct electricity from the hydropower plant to homes and business.

7. How does hydropower produce energy? Powerplants must be located on a water source Power plants capture the energy of falling water to generate electricity A turbine converts the kinetic energy of falling water into mechanical energy Then a generator converts the mechanical energy from the turbine into electrical energy

8. The Lower Granite Dam on the Snake River in Washington state is a hydroelectric dam operated by the U.S. Army Corps of Engineers

9. What would hydropower replace? Fossil Fuels like: –Coal –Natural Gas

10. Advantages over non-renewable Fueled by water, so it's a clean fuel source Doesn't pollute the air like power plants that burn fossil fuels Relies on the water cycle, which is driven by the sun (therefore is renewable) Generally available as needed

11. Creates reservoirs that offer a variety of recreational opportunities fishing, swimming, and boating Most are required to provide some public access to the reservoir to allow the public to take advantage Water supply and flood control More Benefits

12. Can Hydro Become Mainstream? The pros outweigh the cons but there are challenges Expensive to switch from our current energy producing plants to hydroelectricity systems Technology for systems may not be available everywhere Lack of fast flowing water in certain areas

13. Where is this alternative energy being used? Hydroelectricity makes up for 60% of the energy in the Northwest Pros: Most inexpensive form of energy (residents have lower energy bills), up to 240 tons of CO2 from burning coal and gas won’t be put into the air because hydroelectricity is clean for air and water Cons: Many fish passages are blocked by the dams and system equipment, and the water quality and flow may be affected

15. The Future of Hydroelectricity It’s likely that hydroelectricity will become more commonly used, however it’s unlikely that it will become a main source of energy Fast moving water may not be available in certain geographic areas Availability of new technology is also a contributing factor

16. Hydroelectricity in Michigan? Michigan is a good candidate for hydroelectricity Many available bodies of water that are good candidates for producing energy Hydroelectric plant in Ludington, Michigan. This plant has 6 turbines that can produce about 1,872 megawatts.
