1. Read the following article from the Fremont Daily Times and answer the questions that follow.
(a) The students want to reduce the school’s carbon footprint.
(i) Define carbon footprint.
(ii) Identify one way the school’s heating system is likely adding to the school’s carbon footprint.
(iii) Describe one realistic way to reduce the contribution of the heating system to the school’s carbon footprint.
(b) Identify TWO environmental benefits of a living green roof, such as that suggested by Councilperson Fassler.
(c) Describe TWO practices the cafeteria’s food service could use to decrease the environmental impacts of Fremont High School.
(d) Discuss TWO benefits of using native plants for landscaping at Fremont High School.
(e) During the renovation, the carpeting must be replaced. Discuss one environmental benefit of using flooring made of plant material, such as cork or bamboo, instead of carpet made of synthetic fibers.
2. An offshore wind farm project using turbines to generate electricity is to be built along the Atlantic coast of the United States. It will be located about 13 km from the coast in water with an average depth of 10 m.
(a) Describe one environmental benefit associated with an offshore wind project.
(b) Identify and describe one potential economic effect of an offshore wind project.
(c) Describe one additional way, other than wind power, that oceans can provide renewable energy for the generation of electricity.
The project will consist of 200 wind turbines, each with a capacity of 4 megawatts (MW). Each turbine costs $1.2 million to build. Electrical demand in the area to be served by the project is expected to be 2.0 × 106 MWh per year.
(d) Calculate how much electricity (in MWh) the wind project needs to generate per year in order to provide 80% of the annual electrical demand in the service area. Show all work.
(e) Customers in the service area pay $0.20/kWh for electricity. Calculate how much revenue will be produced if the wind turbines provide 80% of the annual electrical demand in the service area. Show all work.
(f) Assuming all turbines are operating, calculate how many hours the wind turbines must operate to provide 80% of the annual electrical demand in the service area. Show all work.
