How do you think factories or furnaces work? Chemistry is a high energy sector, most machines there do not run on electricity.
Or heating your home, hot water, and so on.
Good point but I still don't get how they would use oil and not some oil derivative? Heating, hot water etc. is done with diesel/gas/electricity. Not oil. No?

Maybe oil is just the category overlord for diesel, crude, petroleum and kerosene? Maybe @denlillaapan can clarefiy?
