20. Which of the following is not a consequence of using nuclear energy? a. production of electricity
b. reduction in the use of fossil fuels
c. a safer environment for humans
d. release of less radioactivity into the atmosphere than burning coal

d.

Explanation:

Nuclear energy can create a safer environment for humans.

It can produce electricity.

It releases less radioactivity into the atmosphere than burning coal.

However I found nothing on if it reduces the use of fossil fuels, but in the future it could replace them alongside possibly renewable energy, so take the answer piece of cake.
