What is energy?
Typically, energy is defined as: 'power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.'
Even though there is a simple definition for energy as a whole, it can be broken down into 11 sub-topics, each with its own method harnessing as well as environmental effects.
the 11 types of energy are:

Energy is a measurable substance, and as with all measurable substances, it has its own units of measurement, these are know as the 'Units of Energy'. Each unit of energy has its own corresponding use.
Sustainable energy is energy obtained from non-exhaustible resources. By definition, sustainable energy serves the needs of the present without compromising the ability of future generations to meet their needs.
Natural resources that promote sustainable energy, do not deplete, such as: Hydroelectricity, Solar Energy, wind energy, tidal power, geothermal energy biomass energy and wave power. Sustainable renewable energy is derived from natural sources that either do not deplete or regenerate quickly. |
The primary energy source for the generation of electricity in the State of Victoria is brown coal - one of the largest contributors to Australia's total domestic greenhouse gas emissions and a source of huge controversy for the country. Australia is one the highest polluters of greenhouse gas per capita in the world. Brown coal is used for the generation of approximately 85 percent of Victoria's household, commercial and industrial electricity consumption. The other 15 percent is sourced from natural gas and renewable energy sources - hydro, wind and solar.
