Discuss changes to demand for fuel resources such as coal, petroleum, and natural gas as the demand for energy increases around the world in the modern global economy. Then, discuss the distribution of supply for these resources.

As economies advance, they require more energy.  Given today's focus on greenhouse gases, coal usage will decrease. Natural gas is plentiful and is easily used for heat and as a feedstock for chemical production. Petroleum is also readily available and can be converted to energy and chemicals.

Explanation:  All three resources are transportable and sources are located across the globe. However they require transportation to areas which don't have ready access. This requires roads, railways, pipelines and ships.
