solar power panels
What are the drawbacks to using wind turbines or solar panels for providing all power to a home?
A. The wind and sun are not constant, so there would be times when no electricity would be generated.
B. The wind and sun are constant, so there would be plenty of electricity for the home.
C. Wind and solar power are inefficient and too expensive to use and maintain.
D. Wind and solar power are efficient, but they are not able to produce enough electricity for a single home.
A is the best of your four, for your question, but since individual wind and solar power generate power to a battery, which is the direct source of power to your house, you can store up enough power to maintain your electrical usage, through the winter, power outages, and you can sell some access back to the Community Power Company.
If enough households demand an individual windmill and solar panel, the initial costs will come down to reasonable expense!!
