As the world grapples with the escalating challenges of climate change, identifying strategies that are not only effective but also economical and expedient is crucial.
As global temperatures rise, nations worldwide are exploring cost-effective, rapid-response strategies to mitigate climate change impacts.
Australia, with its rich natural resources and robust economic framework, stands at the forefront of this global effort, pushing aggressively towards a net-zero future.
Australia's commitment to renewable energy is a cornerstone of its climate action strategy.
By 2030, Australia aims to increase its renewable energy production to 50% of its total energy mix.
Investments in solar and wind energy have surged, with solar capacity expected to grow by 12 GW and wind by 16 GW by 2030. These expansions are supported by a AU$20 billion investment in modernising the nation’s electricity grid to handle increased renewable loads.
Recognising the potential of hydrogen as a clean energy source, Australia has launched a AU$1.2 billion hydrogen funding strategy. This initiative targets the production of hydrogen under AU$2 per kilogram, making it competitive with conventional energy sources.
The strategy includes the development of hubs that could generate up to 25 GW of solar and wind power by 2040, specifically for hydrogen production.
Australia's geological formations are favourable for CCS technologies, which are crucial for reducing emissions from industrial sectors.The government has committed AU$300 million to CCS projects, aiming to capture and store up to 15 million tonnes of CO2 annually by 2030.
To reduce emissions from the transport sector, Australia has introduced incentives for electric vehicle buyers and set a target for new car sales to consist of 30% electric vehicles by 2030.
This includes tax rebates and subsidies amounting to AU$3,000 per vehicle, along with a AU$500 million investment in nationwide charging infrastructure.
These measures not only helps in emission reduction but also secures jobs in traditional industries, ensuring an equitable transition to a greener economy.
Transitioning to renewable energy sources like solar and wind is arguably one of the most impactful measures.
The cost of solar panels has decreased by over 80% since 2010, and wind power costs have halved in the same period. By investing in these technologies, it is feasible to achieve up to a 50% reduction in greenhouse gas emissions by 2030 from the energy sector alone.
Enhancing energy efficiency in buildings, industries, and transportation can cut energy consumption by 40% by 2040.
Simple measures, such as upgrading insulation or replacing lighting with LED alternatives, offer returns on investment within 1-3 years,besides reducing the energy bill by 30-80%.
Reducing methane emissions from oil and gas operations is another low-cost, high-impact strategy.
Technological improvements can detect and fix leaks, potentially reducing methane emissions by 45% at a cost of less than $10 perton of CO2 equivalent.
