Write your answers with the correct labels. Where calculations are required, clearly show how you arrived at your answer. Where explanation or discussion is required, support your answers with relevant information and/or specific examples. Nuclear power is an important source of energy around the world. Some countries, such as France and Ukraine, generate more than 50 percent of their electricity from nuclear power plants. However, generating electricity from nuclear power plants can lead to environmental problems. (a) Describe one potential negative environmental consequence from using nuclear power. (b) Proponents of wind energy argue that wind turbines are a better way to generate electricity. i. Describe TWO potential advantages, other than reducing the negative consequences from using nuclear power, of generating electricity using wind turbines. ii. Describe one potential disadvantage of generating electricity using wind turbines. (c) The total wind power capacity in the United States in 2000 was about 2540MW. By 2015, the total wind power capacity in the United States was about 72,500MW. Calculate the percent change in the total wind power capacity in the United States from 2000 to 2015. Show your work. (d) A wind turbine has a capacity of 3MW. Assuming the turbine operates at 50 percent of its capacity all day and every day for a week, calculate how many kWh of electricity the wind turbine will produce by the end of the week. Show your work. (e) If a typical house uses 10,900kWh per year, calculate how many houses could have their full energy needs provided for one year by the turbine above if it continued to operate as described for one year. Show your work.
