Introduction to hydropower What is hydropower? Hydropower generation Environmental impacts Examples of hydropower projects Turbine design principles Computer lesson Working in pairs design your own turbine

What is hydropower? Is a form of renewable energy that uses the water stored in dams or flowing rivers to create electricity. The water is moved through a turbine that spins a generator that converts the mechanical energy into electrical energy.

Hydropower Generation About 13% of the renewable energy in the US comes from hydropower Of this 6 to 7% is from hydropower. Most of the hydropower generated in the US is in the Pacific Northwest

Environmental Impacts Does not pollute water or the air Fish migration Reduced CO 2 emissions Removal of plants and animals Change is flow regime

Types of Hydropower Projects Impoundments Most common (2, 400 of the 80, 000 dams produce power) Hoover dam Diversions, aka run-of-the river Niagara Falls Pump storage Silvette, Austria

Sizes of hydropower LARGE HYDROPOWER Although definitions vary, DOE defines large hydropower as facilities that have a capacity of more than 30 megawatts (MW). SMALL HYDROPOWER Although definitions vary, DOE defines small hydropower as projects that generate 10 MW or less of power. MICRO HYDROPOWER A micro hydropower plant has a capacity of up to 100 kilowatts. A small or micro-hydroelectric power system can produce enough electricity for a home, farm, ranch, or village.

Turbine design principles Forced movement using water density, gravity, and velocity Pitch Size Number of blades Shape Scoping of the blades

KAEE 2017 3 D Solid. Works is software used in most postsecondary engineering programs Professional and includes many different tools Has very high precision Not very intuitive or user-friendly; most would need to be taught by person familiar with software Fairly expensive; one copy of the Student Edition is $150 https: //store. solidworks. com/studentstore/default. php
