Renewable energy in Australia represents 5.2% of total energy consumption, but only 1.7% of total production, the difference being the result of significant non-renewable energy exports. In the five years to 2009 renewable energy consumption grew by 3.5%, faster than other energy sources. Of all renewable energy sources, hydro represents 63.4%, wind 22.9%, bioenergy 11.5%. photovoltaic 2.1%, and other sources (such as wave and tidal, solar thermal, and geothermal) 0.042%. Note that these figures exclude a significant amount of energy saved through use of solar water heating units as they do not actually produce electricity; this is calculated separately to be 7.4% of clean energy production. Biogas had the fastest rate of growth in 2008-09 with around 33%, followed by solar and wind with 6.5%.
In the year to October 2010 Australian electricity production was 251 TWh, with an estimated 21,751 GWh or 8.67% generated from renewables, and 91.33% from fossil fuels (note: this excludes a further approximately 1.6 GWh produced through solar water heating). This compares to 2006 figures, where approximately 9,500 GWh of electricity came from renewable sources, representing less than 4% of electricity consumption for that year.
