What is the result of the worldwide use of cleaner energy sources?
a. rise in ocean levels
b. reduction in acid rain
c. increased desertification in the sahel
d. decreased desalinization plants in the middle east

I think the best answer from the choices listed above is option B. The  result of the worldwide use of cleaner energy sources is the reduction in acid rain. This is because there will be less release of gases to the atmosphere that could cause acid rain. Hope this answers the question.
