Question

6. No source of energy can be completely pollution free.​

Answer 1

I AM AGREE WITH THIS STATEMENT.

REALLY TRUE!

Answer 2

Answer:

No source of energy can be called pollution-free, because, the use of any source of energy disturbs the environment in one way or the other. A source of energy like a solar cell is pollution free in actual operation but the assembly of the device might have caused some damage to the environment.
