Looking at the wind speed map of Florida, which regions, if any, might be suitable for wind energy production, and why?

Multiple Choice

Based on the information provided and the map, why is wind not considered a productive resource in most parts of Florida?

• Because the average yearly wind speed in most areas is below 6.5 m/s

• Because Florida does not have enough land area

• Because wind turbines cannot be built in Florida

• Because the temperature is too high for wind energy
