SJSU ENVS 119 Final Study Guide
Questions and Correct Verified
Answers Latest Version
How is the potential wind power output calculated for a specific site and
turbine? (Formula)
✓ P=0.5 x p x Cp x v^3 x As
✓
✓ p= 1.2kg/m^3
✓ Cp= energy coefficient (.4-.5)
✓ v^3= meters per second (double wind speeds=8 fold in power)
✓ As=m^2 (area swept by blade)
How can the social gap in renewable energy be overcome?
✓ Include more people in the conversation and what could be the
benefit.
Define « intermittent » for wind energy. Why is it a problem?
✓ Wind energy can be on/off depending on the weather.
Primary source of power for wind energy?
