Document Summary
Energy consumption has been growing the most rapidly in transport. It is only transport that has increased from 23% to 27%. In 1973, transport counted for as much as 45% of oil use today it counts for as much as 62% (nearly two thirds of all petroleum consumption) This is profoundly important from the perspective of geo-political security. Use of petroleum in the transport sector is the hardest to change. These two graphics taken together show the great importance of having liquid fuels in transport more than in every other sector which have high volume content. It is important because it is in transport that you want your fuel consumption to take as little space as possible but to give as much output as possible, high volumetric density. (we want little payload). This is why it is very difficult to implement alternatives to liquid petroleum fuels in transport more than in any other sector.
