For natural gas
One cubic foot of natural gas produces about 1,030 BTU (38.4 MJ/m³)
The price of natural gas is $9.00 per thousand cubic feet ($0.32/m³)
For heating oil
One US gallon of heating oil produces about 138,500 BTU (38.6 MJ/l)
The price of heating oil is $2.50 per US gallon ($0.66/l)
This gives a cost of $8.70 per million BTU ($8.30/GJ) for natural gas, as compared to $18 per million BTU ($17/GJ) for fuel oil. Of course, such comparisons fluctuate with time and vary from place to place dependant on the cost of the raw materials and local taxation.
Natural Gas is a vital component of the world's supply of energy. It is one of the cleanest, safest, and most useful of all energy sources. Despite its importance, however, there are many misconceptions about natural gas. For instance, the word 'gas' itself has a variety of different uses, and meanings. When we fuel our car, we put 'gas' in it. However, the gasoline that goes into your vehicle, while a fossil fuel itself, is very different from natural gas. The 'gas' in the common barbecue is actually propane, which, while closely associated and commonly found in natural gas, is not really natural gas itself. While commonly grouped in with other fossil fuels and sources of energy, there are many characteristics of natural gas that make it unique. Below is a bit of background information about natural gas, what exactly it is, how it is formed, and how it is found in nature.
