How do renewable energies differ from non-renewables?
Fossil fuels, such as coal, oil and natural gas, come from carbon-based organic materials and take many millions of years to form. Using them to generate electricity produces greenhouse gases, and they aren’t considered sustainable.
Renewables are not based on carbon materials; instead they are from sources that are constantly replenished by nature. They do not produce greenhouse gases when used to produce electricity.
The future of renewable energy
The new Renewable Energy Target (RET) was passed by parliament in June 2015 and provides for 33,000 gigawatt hours of large scale generation to be sourced from renewables by 2020.
The RET offers an incentive to deploy wind and other low carbon forms of electricity as part of the response to climate change. The RET is incorporated into the costs you pay on your standard electricity bill.
There are other government policies supporting less mature renewable technologies, such as geothermal, large scale solar and marine energy. The Australian Renewable Energy Agency and Clean Energy Finance Corporation are two government entities supporting these types of emerging technologies.
A challenge facing the future of renewable energy is the intermittency of the fuel sources. When the wind isn’t blowing and sun isn’t shining, energy can’t be generated. We are trialing batteries for home use and hope to have a produce on the market later this year.
