Extraction and transport

Natural gas is extracted by drilling through the earth down to where the gas is. A pipe is then fitted down the hole. This pipe is then connected to a series of pipes which transport the gas to a central storage area. This can then be transported to powerplants to generate electricity or directly to houses.
The Mortlake power station's gas is supplied through an 83km underground transmission pipeline. The gas is pumped from the Port Campbell offshore gas plant all the way to the powerstation.
Natural gas is a chemical energy (potential) when it moves through the pipelines it stays potential. When it reaches the power station it is put into an air compressor which turns it into heat energy. It then is burnt turning it into kinetic energy. It then goes through a combustor which turns it into heat energy. This heat energy is hot gas which spins the turbine, creating electricity (electrical energy). This electricity is sent through a tranmission line with high voltage and reaches homes with low voltage. This helps save energy.
This whole conversion is only 30% efficient. Most of the energy is lost when burnt and the rest is lost during the other conversions and when being transmitted to homes. It would be more efficient if a few of the unnecassary conversions were removed.

Wind plants use wind turbines to extract power from the wind. When wind blows on the turbine's propeller it causes them to rotate. This can then create electricity.
The turbines were constructed in Denmark and then shipped to Australia in pieces. Concrete and other materials were also shipped from different places in Australia to Macarthur.
The fisrt energy conversion is wind power (kinetic) which then rotates the turbines propellar, converting the energy into mechanical energy (kinetic). This then generates electricty turning it into electrical energy (kinetic).
This whole conversion is almost 100% efficient
