This was the conclusion of a study made by Andrew Blakers, director of the Australian National University’s Centre for Sustainable Energy Systems. The same study cites that solar photovoltaics and energy make up almost all new electricity generation in the previous years.
Blakers noted that if the trend continues, the country will be able to achieve renewable energy system by 2040, with renewables replacing existing fossil fuel-based power stations which should have been exhausted by that time.
The researcher said that South Australia is now getting 29 per cent of its energy requirements from wind and solar power. More people in the region are shopping for cheap solar panel quotes, or getting solar power rebates and inquiring about solar installer packages.
Cheaper
Like what Bloomberg New Energy Finance notes, wind is cheaper than coal and gas-fired energy generation. Solar power will soon follow this path. This means that the costs related to the tapping of these new and renewable energy sources will be no greater than fossil fuel-based power stations. This projection is considered critical, since renewables like solar power and wind are misconceived as being more expensive than fossil fuel plants.
Blakers said that his projection is similar to the conservative forecasts done by the Bureau of Resource and Energy Economics (BNEF).
The 100% renewable scenario by 2040 is seen as almost similar to forecasts made by other outfits. Australia has been sourcing 10 per cent of its energy requirements from renewables in 2010. This figures to rise to at least 25 per cent ten years later, with the lower solar power quotes, more solar power rebates and the use of advanced solar installer systems coming into play as well as the 41,000GWh target for large scale renewables.
According to BNEF, the trend could be 46% for renewables by 2030 with wind and solar energy replacing fossil fuel-based plants, with the retirements of the latter accelerating in the next ten years.
Other scenarios
Blaker’s research also pointed out other scenarios that could play a role in solar and wind energy completely replacing fossil fuels as the main source of energy in Australia by 2040.
These include new capacity to replace fossil fuel systems is exclusive to wind and solar, meaning there are no new gas or coal plants established. Existing hydro and other renewable forms of energy is continued but not increased, and installation rates of wind and photovoltaic are at 1GWh a year to meet the renewable energy target of the government by 2020.
Blakers also said that for the country to be fully dependent on renewables by 2040, it should continue to install 1 GW of wind every year until 2040. Installation rate of 1 GW of solar energy should also be kept until 2020 and then grow by 10 per cent every year after.
