If the oil supply gets exhauted one day,how would this affect our life style?

Remember the old movies...like horse and buggy..i think that answers it.If the oil supply gets exhauted one day,how would this affect our life style?
As we run out oil will become more expensive so we will gradually shift to other sources of energy that are now more expensive than oil and we will also use less energy because of the cost. Most of the change in the amount of energy we use will be accomplished through conservation so we will not see much difference in out life style, smaller cars and maybe smaller houses.If the oil supply gets exhauted one day,how would this affect our life style?
Technology will settle the issue. We are currently working towards alternative energy sources, as the supply of oil continues to become more and more of a problem, a lot more effort will be spent working on alternatives to make them more feasible. We do not know yet what will eventually replace oil, who knows maybe we will end up with something that could dramatically alter and improve our life style. But then again, maybe we will have to settle for something more expensive, in which case we would have to settle for less consumption, travel, etc.
Serious efforts are now being made so that our life-style will not be greatly affected by oil shortages and high fuel prices that result. However most new energy sources are more costly than oil, so you can expect a greater amount of human physical effort to be associated in our future life-style with a larger proportion of people being less obese and a lot more healthy.
