B. natural gas has still accounted for far less of the energy consumed in the United States as oil
C. natural gas still has accounted for far less of the energy consumed in the United States as oil has
D. still far less of the energy consumed in the United States has been accounted for by natural gas as by oil
E. still far less of the energy consumed in the United States has been accounted for by natural gas than has oil
First, ask yourself what has been widely used for decades to fuel homes? Clearly, natural gas. Eliminate D and E.

Next, the proper idiom is less than, not less as. Eliminate B and C.
