Energy efficiency could have twice the impact of renewable energy, nuclear and clean coal combined, according to the Energy Efficiency Council of Australia.
Large scale energy efficiency is a ‘missing piece’ in Australia’s plans to curb greenhouse emissions, according to the Council’s 2010 policy platform, which calls for 50 Mt of carbon emissions reductions to come from efficiency. Its seven-point plan would also save A$5 billion a year and protect consumes from price increases by making the country’s power system work better.
The three major policies to transform Australia and put it on track to meet GHG targets are:
* A national energy efficiency target
* A requirement for investment in efficiency by power networks
* A national efficiency scheme to replace the current state-by-state approach.
The policies were developed over the past year, and are based on successful programmes in in other countries. The European Union, United States and China all have strong national efficiency targets for 2020, and the Council says the Australian government can deliver significant energy savings in four key areas: buildings, industry, cogeneration and government operations.
Efficiency to have more impact than renewables
The International Energy Agency estimates that energy efficiency will deliver 65% of global carbon cuts in the energy sector by 2020, and 54% by 2030. The Australian Bureau of Agricultural & Research Economics estimate that energy efficiency will account for 55% of Australia’s cuts in GHG emissions over the next 40 years.
“Even if Australia introduced a price on carbon tomorrow, we would still need strong energy efficiency policies,” the report explains. “The European Union has had an emissions trading scheme since 2005 and also has more ambitious energy efficiency policies than Australia.”
“As there are many barriers to energy efficiency, we need several key energy efficiency policies,” it adds. “The major delay to a carbon price means that energy efficiency is now critical.”
“The Australian Government has a number of policies to ensure that 20% of energy will come from renewable sources by 2020; however, even with more renewable energy, emissions from fossil fuels will still increase if energy demand continues to increase at its current rate,” it explains. “Energy efficiency policies would reduce the growth in energy demand, putting Australia on track to meet its international greenhouse targets.”
Grid improvements needed to handle increased demand
Australia’s grid will spend A$42 bn over the next five years, of which one-third is just to cope with increased power demand. “We desperately need measures to direct some of this towards smarter ways to cut electricity waste.”
“Energy efficiency is nearly half the country’s greenhouse solution and it pays itself back,” says Rob Murray-Leach of the Energy Efficiency Council. “To take a World Cup metaphor, it should be more like our lead striker, to implement solutions across the whole economy, but right now it is still warming up on sidelines.”

Use of Renewable Energy versus Fossil fuels
As we discussed before, fossil fuels resources are used up rapidly without any chance for their bringing back to initial state.
On the other hand we learned about enormous energy of sun almost everlasting. Meanwhile, wind, water; forests and recyclable garbage have a potential of renovation. Stuffs such as sawdust, leftover crops, even livestock manure have the ability produce electricity.
Collectively we call them “bio mass”.
Clean energy sources like wind, water, sunlight without harming the environment, can be used to produce our needed energy.
In a sharp contrast, burning of fossil fuels in cars and factories has a great affect on atmosphere.
Air pollution results to so call greenhouse effect.
Gases like carbon dioxide are emitted from burning this sort of fuels.
Recycling is a way of wasting our money and our resources drawback as the toxic fluids in solar systems piping or clearing the forests and crop fields for the purpose of installing windmills, mirrors, power lines.
Solar cells have similar technology like silicon chips uses toxic chemicals.
Also, we should mention the limited capacity of some of these resources for instance. All the stalled solar systems have a limited power of just 350 MW far less than energy produced by fossil fuels.
As well, the cost of producing is yet four times the conventional fossil fueled power plants.
There fore, renewable power plants are not yet a match to cheaper fossil fueled energy.
Wind has its own drawback, mostly because of land use.
Producing energy for about 1000 homes requires an area equal to 17 acre.
Birds' collision to blades is another distressing of wind mills.
Geothermal energy is limited to some points of the world, have a high rate of corrosion in its piping network.
Its maintenance and drilling costs have made it a little bit more expensive that gas fired power plants.
Hydroelectric energy by using dams displaces people and damages its surrounding farmlands.
Air pollution is main characteristic of fossil fuels. Fuel changes to sort of environmental impact to better of environmental impact.
To better compare, it is suggested to prepare a full list of pros and cons of all available energies.
