Water+Power

__**WATeR POWER**__ By: Albert Wakhloo, Jamie Zimmerman, & Harrison Savage.

Important Vocab: HydroElectric: Generation of electricity via flowing water. Dam: A "wall" but around a body of water to contain the water and usually to create electricity via the flowing water. The turbine put inside the wall. The turbine turn the kinetic energy of the flowing water to electricity. Turbine: A machine used to turn kinetic energy into electricity.

Water Power Production: [2] 1. Find a flowing body of water. 2. Create a dam. 3. Create an intake 4. Create a penstock connecting to the intake and turbine. 5. Place the turbine in between the penstock and generator. 6. The turbine will turn the kinetic energy of the water into electricity, and send it through the generator into the powerhouse, then to the power lines to its destination. 7. The water flow will then lead into the outflow river, to one side of the dam.

Advantages: -Does not pollute air [1] -Expands irrigation [1] -Cheap [1] -Reusable [1] -Provides drinking water [1] -Easier for third world countries to generate power(if they have a water supply) [1] -Provides water for 30% of the world’s irrigated land [1] -Provides 19% of electricity [1] -Expands irrigation [1] -Supplies hydroelectric energy (falling water used to run turbines) [1]

Disadvantages: -Destabilizes marine ecosystems [1] -Dam building is very costly [1] -People have to relocate [1] -Some dams have to be torn down (Some older ones are not stable.) [1] -Restricted to areas with flowing water [1] -Pollution affects water power [1] -Flooding of available land that could be used for agriculture [1]

Conservation of Energy: -The water will be stopped by the dam and forced downward -It will then go through the intake and go through the penstock -The turbine will then turn the water into kinetic energy -The kinetic energy will be sent upward into the generator turning it into electric energy -The electric energy will then be sent through the the powerhouse and sent through the powerlines
