being faced for large-scale utilization of Australia’s clean energy resources. Changes in regulatory and approval
processes are affecting well-established technologies like wind farms in some locations. It is often stated that the
deployment of alternative energy resources will require a great deal of new research and development effort.
The renewable energy technologies are too sophisticated and complex compared to conventional energy conver-
sion technique. Due to the higher initial investment cost the renewable energy technology is not fully used yet.
Despite these challenges, the deployment of clean energy technologies is gathering pace, and is expected to play
a critical role in moving to a low emissions future while meeting Australia’s continued demand for energy [4,6].
4. Conclusions
The following conclusions can be drawn from this review.
• Total energy production (which includes energy exports) in 2011-12 increased by 5%, relative to 2010-11, to
total 17,460 petajoules, reflecting strong growth in natural gas (8%), black and brown coal (5% and 6%) and
uranium (6%) production. Production of crude oil and liquefied petroleum gas fell 6%, and renewable ener-
gy decreased by 7% in 2011-12 compared to 2010-11.
• Total energy consumption, increased by 2%, relative to 2010-11, to total 6194 petajoules in 2011-12. The
result was mainly driven by strong growth in energy use in the commercial and services sector and modest
growth in the transport, mining, agricultural and residential sectors. Energy consumption in manufacturing
and construction, however, decreased in 2011-12 relative to 2010-11.
• In 2011-12 consumption of renewable energy declined by 7%, relative to 2010-11, largely due to a fall in
hydro energy consumption associated with lower hydroelectricity output in southeast Australia due to re-
duced water in-flows. Reduced hydro energy consumption more than offset the very strong growth observed
in wind and solar energy.
• The prospect of renewable energy is more in Australia which will make a great contribution to Australia’s
energy economy in near future.
• The authors concluded that the Australia’s renewable energy economic is viable; if its undeveloped renew-
able energy can be used effectively for electricity generation and transport sector.
