Hydropower Sawyer and Nadeem

How Does It Work?

● Dam ● Penstock ● Power House ● Turbine ● Generator ● Power Lines ● Outlet for water Machinery/Process

● Provides 17.5% of the worlds electricity Energy Efficiency Ratio

Where it is used most?

Environmental consequences Silt buildup, barrier for fish Expensive Droughts Few places where dams could be built Problems Hydropower can face

Fossil Fuels vs. Hydropower AdvantagesDisadvantages Constant powerMore expensive than fossil fuels to start Does not pollute atmosphereMuch less profitable than fossil fuels (at least at first) Can be used for many decadesFlooding Can be shut down when energy demand is low Geological damage RenewableDroughts Can create water reservoirs
