Small problem BP and Shell untill they decide to change from mainly supplying and selling oill the uk goverment will not be doing to much the same in the Us and many other western countries.
The West just went to war for petrol and oill so untill they have discovered ways to produce the fuel by alternative ways controlled by the west and the oil companies. Many of the alcohol versions from what i heard/read would take up to much land and would hinder food production so untill made more efficent i doubt much will change.
