Explain the advantages and disadvantages of wind-powered electrical systems.

Explanation should include discussion of

• variable wind speed in most areas of the country
• greenhouse gas release with burning fossil fuels to produce energy vs. the clean electrical production from wind turbines
• the carbon dioxide (CO₂)/ greenhouse gases released as a result of initial wind turbine construction.
• output of wind turbines

Process/Skill Questions:

• What is the cost of wind power per kilowatt-hour?
• What is the cost of small wind vs. utility wind?
• What are the benefits of generating power from wind energy?
• How does the condition of the electrical grid affect the ability to produce wind power economically?
• How does the geographic concentration of the population correlate to the location of most of the wind farms in the United States?
• How would battery storage help with the issue of variable wind speeds?
