Final answer:
Humans do not eliminate the use of fossil fuels and use wind for all their power needs due to wind being a nonrenewable resource and the inconsistency of wind power in different locations.
Step-by-step explanation:
Humans do not eliminate the use of fossil fuels and use wind for all their power needs for two reasons:
- Wind is a nonrenewable resource and people want to save some of it for future generations to use.
- Wind power can only produce electricity consistently in places where the wind blows consistently, and wind does not blow consistently in every place on Earth where people use electricity.
These two factors limit the complete replacement of fossil fuels with wind power.
