EGEE 101 – Midterm #3 – Energy and Environmental Engineering – study
material
- correct answer ✔✔The main difference between land use for solar and wind land leased for wind
turbines can be used for other purposes up to the base of the turbine, whereas land leased for solar
panels must be dedicated to the panels
1 Million - correct answer ✔✔How many people were relocated to complete the Three Gorges Dam?
10% - correct answer ✔✔After a uranium based fuel rod has spent 3 years in a reactor, how much of
its uranium has been used?
13 Million Celsius - correct answer ✔✔The temperature at which nuclear fusion becomes possible
1600 Panels - correct answer ✔✔Suppose a PV farm requires 2,000 panels to generate power at 20%
efficiency. If a new panel were invented that was 25% efficient, how many panels would be required?
20% - correct answer ✔✔What percentage of the world's electricity comes from hydroelectric dams?
24 Acres - correct answer ✔✔If a solar farm requires 40 acres in Iowa (210 sunny days per year), how
much land would it require in Nevada (350 sunny days per year)?
3-4% - correct answer ✔✔Nuclear fuel rods are _____ uranium by concentration
4 Billion - correct answer ✔✔The amount of subsidies paid out to wind power producers in 2016
44,145 Watts - correct answer ✔✔If h = 3 meters, q = 3 cubic meters per second, and efficiency is
50%, what is the power output in watts? Assume 9.81
5 MW - correct answer ✔✔If a solar farm generates 10 MW in Arizona (320 sunny days per year) is
moved to Pennsylvania (160 sunny days per year), what is the new power output?
