Oil is forecast to remain the primary source of energy for the world’s economies through at least 2040 according to energy projections.  Oil is expected to supply 32% of the world’s energy in 2040, down slightly from 34% in 2010.  Overall, oil, natural gas and coal will provide 78% of energy demand followed by nuclear then alternative sources of energy such as wind, solar and biofuels.  While alternative energy sources are seeing continued growth, these sources will only provide about 4% of the total world demand in 2040.
