Helping Australians Power a Sustainable Future
Australia’s Emissions and Energy: A Comprehensive Overview
Australia is at a critical juncture in its energy history as it grapples with the challenge of reducing carbon emissions. In September 2023, it was reported that the coal industry was investing hundreds of millions of dollars in low-emission technology. This technology aims to extend the lifespan of vital base-load electricity generators while significantly reducing carbon emissions from the manufacturing industry.
Investing in a Greener Future
Australia’s black coal producers have committed over $550 million since 2006 to develop strategies for capturing carbon emissions, with the goal of storage, reuse, or prevention. The urgency behind this investment is evident, as nearly two-thirds of Australia’s coal-fired electricity generators are expected to close by 2033. The closure of these generators poses a reliability risk to the national power grid, demanding “imminent and urgent investment.”
The Role of Carbon Capture and Storage (CCS)
Carbon Capture and Storage (CCS) technology plays a pivotal role in this transition. CCS involves capturing carbon dioxide and safely storing it underground, directly from large emission sources like coal-fired power plants. It’s a crucial technology in achieving net-zero emissions, as it can prevent more than 95 percent of CO2 emissions from entering the atmosphere.
Australia's Energy Landscape
- Energy Mix:
Fossil fuels still contribute significantly to Australia’s energy generation. In 2021, fossil fuels accounted for 71% of total electricity generation. This includes coal (51%), gas (18%), and oil (2%). The share of renewables in total electricity generation in 2021 was 29%, with solar (12%), wind (10%), and hydro (6%) leading the charge.
- Efficiency Comparison:
Solar energy is the most environmentally efficient, while coal and natural gas are more efficient for reliable energy production. Solar panels have an efficiency of 15% to 22%, while coal boasts an efficiency of up to 40%, and natural gas can reach up to 60%.
- Carbon Emissions:
Australia’s total greenhouse gas emissions for the year to March 2022 were 487.1 million tonnes of CO2-equivalent (Mt CO2-e), up 1.5% from the previous year. This increase was attributed to various sectors, including electricity, transport, stationary energy (excluding electricity), agriculture, and fugitive emissions.
- Renewable Energy Growth:
Renewable energy’s share of total electricity generation has been steadily increasing. In 2021, it accounted for 35.9% of Australia’s electricity generation, up from 32.5% in 2020. Solar and wind energy have been key drivers of this growth.
Can Australia Achieve 100% Renewable Energy?
Reports suggest that Australia could achieve 100% renewable energy for certain periods of the day by 2025 if current rates of wind and solar development continue. A 2021 report stated that an expanded renewable energy base is possible for Australia with the right technologies and policies. It is estimated that a 100% renewable energy supply is technically possible by 2030, using proven technologies, at a cost of $370 billion over 10 years.

The 82% Renewable Energy Target
The Labor Party’s “Rewiring the Nation” policy, part of the Powering Australia Plan, aims to increase renewable generation in the National Electricity Market to 82% by 2030. This policy could help Australia reach its updated target of 43% carbon reduction by 2030.
In conclusion, Australia stands at a pivotal moment in its energy journey. The transition to cleaner, more sustainable energy sources is essential to reduce carbon emissions and secure a greener future. As renewables continue to grow and technology advances, Australia has the opportunity to lead the way in sustainable energy solutions.
