Energy is defined as the capacity to do work. There are many different types of energy such as kinetic, potential, and radiant among others. From little fires to large nuclear power plants, energy is always being used. Energy can be measured in any of several units: BTU, Joules or kilowatt-hours, for example. Since, the values for the energy consumption of an entire continent are so large, often units such as petajoules (PJ = 1015 J) and exojoules (EJ = 1018 J) are used to measure the quantity of enerfgy consumption
Although energy can be measured, it is often hard to determine the exact energy that is consumed by a particular region. However, it is safe to conclude that as an area gets more populous and larger there will be more energy consumed in that area. Even though there are no exact numbers for the consumption of energy in certain parts of the world, there are good estimates of the total energy consumed in these places.
When we take a look at Australia we can detect certain trends that relate to the consumption of energy. According to data from the World Resources Institute, the total commercial energy consumed in 1993 was 3.92 EJ. This was a major increase of 99% from 1973. We can also look at the total energy consumed in 1993 and the projected energy consumed in 2014. If the projected data are correct there will be a 55% (5.698 EJ) in the energy consumed from 1993 to 2014. Recent energy consumption has been on the order of 1 EJ per year. It is expected to reach nearly 10 EJ per year within the next 15 years.
