Which of the following is a problem with using solar power as a main source of energy?

A. People do not yet have the technology to use solar power***

B. The sun is not close enough to provide solar energy

C. Power from solar energy contains a large amount of harmful

D. Solar power is not available at night or when it is cloudy

I am confused. I think it's a because I never heard of a device like that

  1. Solar power is energy that comes from the sun. Its not A, because people have already invented solar panels. Solar panels are panels that you can install on the roof of your house to use solar energy. It's not B either, because if the sun wasn't close enough then how can we use solar power today. What do you think the answer is now, its either C or D

  6. It is D because D is the only one that makes sense because if it's night and the solar panel is controlled by the sun how is it going to work at night? There isn't any sun at night (it's not controlled by the moon either) So it is D

  7. Your answer is D, Because when it gets dark or cloudy you cant gain energy and when that happens you can run out of energy and the power go out.

  8. but solar panels build up energy when they are exposed to the sun, so you can use the power at night. but im pretty sure it doesn't produce ultraviolet rays, so idk anymore im goin with d
