Question

Many communities rely on solar energy for daily life uses.

Answer 1

Answer:

This would affect the communities that use solar energy greatly, in a negative way.  

Explanation:

If the moon were twice its size, and cast a larger shadow on Earth, the shadow would black out the earth to an almost night time, during the day.  We would have a 24+ hour night, and communities relying on nothing but solar energy would be out of power until the sun was out again.
