Between the car makers themselves making moves away from gasoline and diesel fueled vehicles and the various national and regional enactments of policies also mandating the transition away from fossil fuels, the oil industry and oil-producing nations may find very much leaner times in the future. Even the US military is starting to dip their toes in the alternative fuel/power pool:

What a lot of the public doesn't realize is for a long time it has been the policy of US military field units not to use gas or diesel fuels found in the areas to which they are deployed; the main reason is the lack of trust in the quality of the local fuels and the possible effects local fuels could have on the performance of military vehicles and the possibility of fuel being sabotaged by locals. This means all fuel used by military vehicles in the field must be transported from the US or US-trusted origins and humped out to the vehicles as they move into an area. As an example, in the oil rich country of Iraq, none of the local fuel was to be used by US military units; all fuel had to be shipped in; its kind of like being in the middle of a supermarket and not being allowed to eat any of the food while waiting for your take-out order to arrive. The ability to have the fuel source move forward with field units and having that source easily renewed is major. An extra big bonus is the "stealthier" nature of non-combustion engines; any one who has stepped off a curb only to be forced back by a hybrid or electric car knows how very silent they are...
