The world's use of fossil fuels has nearly doubled since ______.
The world use of fossil fuels has nearly doubled since 1900. Fossil fuels are not a renewable energy resource.

This is an exacting problem for oil, because we also use it to make plastics and many other products.
Thus, the correct option is A.
