Leave it on?

It works is not the same as it works well. Do any of you read? Or do you just read "approved" texts? 

@mylogic I suppose you believe that oil is bad, but you would not have an audio system without it, even if you use solar power.

Invalid question above

Oil is okay with no other choices.

Coal was okay before oil (dirtier and less efficient than oil)

Wood burning fires since the dawn of man and out of necessity were okay (new wood burning fires installed in the home by choice today, not such a good idea)

Going forward it is a question of using less carbon fuels, and everyone is capable of contributing to a solution.

Choices that can be made today. 

@mylogic  many thousands of products are made from oil, how much do you think all those products will cost if we aren't using carbon fuels? 

@invalid 

As l said, oil is okay with no other choices. 
 

Your last question to me in unanswerable.
