Renewable energy in Australia: What you need to know
Renewable energy has become a major focus in recent years, with nations worldwide shifting towards cleaner and more sustainable energy sources. Australia is no exception, as there are growing pressures to expand its renewable energy efforts and keep pace with global trends.
But what does renewable energy mean, and how is it being adopted across Australia?
In this article, we’ll explore the basics of renewable energy, how it works in Australia, and what it could mean for you as a consumer. From solar power to wind farms, we’ll break down the current landscape and future possibilities of renewable energy in Australia.
What is renewable energy?
Renewable energy comes from natural sources that never run out or can be quickly replenished. Unlike fossil fuels such as coal or gas, renewable energy sources—like sunlight, wind, and water—are naturally abundant and constantly available.
These sources are used to generate electricity without producing harmful emissions, making them cleaner and more sustainable for the environment. In simple terms, renewable energy is energy that can be used repeatedly without depleting the planet’s resources.
How are non-renewable resources different?
Non-renewable energy sources come from materials that take millions of years to form and are limited in supply. In Australia, the main non-renewable sources are fossil fuels, including coal, natural gas, and oil. These materials are extracted from the earth and burned to produce electricity or power industries. While they’ve been the backbone of energy production for decades, they come with several downsides.
Firstly, non-renewable sources are finite, meaning once they’re used up, they can’t be replaced in a short amount of time. This creates a long-term problem as supplies will eventually deplete, leading to higher costs and potential energy shortages. Secondly, the process of burning fossil fuels releases large amounts of carbon dioxide and other harmful greenhouse gases into the atmosphere, contributing to climate change and environmental damage.
In contrast, renewable energy sources like solar, wind, and hydro are virtually limitless and don’t pollute the air or contribute to global warming. Renewable energy can be generated over and over again without depleting the Earth’s resources, making it a cleaner and more sustainable option for the future.
The major difference between renewable and non-renewable energy lies in their availability and environmental impact. While non-renewable sources provide reliable energy now, they come at a cost to both the planet and future generations, whereas renewable energy offers a cleaner, long-lasting solution.

As the country continues to shift away from fossil fuels and embrace renewable energy technologies, it stands to gain from a cleaner, more sustainable, and economically prosperous future.
What’s the difference between carbon neutral and renewable energy?
Renewable energy and carbon-neutral options are both aimed at reducing the impact on the environment, but they are different concepts. Here’s a simple explanation of how they differ:
Renewable energy
Renewable energy comes from natural sources that are constantly replenished, such as sunlight, wind, water (hydropower), and biomass (organic materials like plant waste).
The key feature of renewable energy is that it doesn’t run out and doesn’t create harmful emissions when generating power.
Examples of renewable energy | Solar panels, wind turbines, hydroelectric dams |
Environmental impact | Since renewable energy doesn’t rely on burning fuels, it produces little to no greenhouse gases or pollution. It’s a clean and sustainable way to generate electricity |
How it works | Renewable sources are directly used to create energy. For instance, solar panels convert sunlight into electricity, while wind turbines use wind to generate power |
Carbon neutral options
Carbon-neutral options focus on balancing out the carbon dioxide (CO2) emissions created by certain activities, like burning fossil fuels or manufacturing. These activities release CO2, a greenhouse gas that contributes to climate change, into the atmosphere.
To achieve carbon neutrality, companies or individuals try to “offset” or “neutralise” the amount of carbon they emit by supporting activities that reduce or remove CO2 from the air.
Examples of carbon-neutral actions | Buying carbon offsets, planting trees, or investing in renewable energy projects |
Environmental impact | Carbon-neutral activities still generate emissions, but the aim is to balance them out by reducing emissions elsewhere or capturing carbon from the air |
How it works | If a company burns fuel to make a product, it will invest in projects that reduce or capture the same amount of CO2, making the overall impact on the environment “neutral.” For example, a business might buy carbon credits to fund reforestation (planting trees that absorb CO2) |
Key differences
- Source of energy. Renewable energy comes from natural sources like the sun and wind, while carbon-neutral options might still use fossil fuels but balance out their emissions through carbon-offset programs.
- Emissions. Renewable energy doesn’t create harmful emissions during power generation, while carbon-neutral options may still produce CO2 but aim to cancel it out by compensating elsewhere.
- Sustainability. Renewable energy is naturally sustainable, as the sources don’t run out and are available indefinitely. Carbon-neutral options don’t necessarily use sustainable sources, but they focus on reducing the net environmental impact.
In short, renewable energy avoids emissions by using clean, natural sources, while carbon-neutral options manage emissions by balancing out the CO2 released with efforts to reduce or remove it elsewhere.
Renewable energy is typically a cleaner and more straightforward way to cut emissions, while carbon neutrality is more about offsetting the environmental cost of using traditional energy sources.
Is renewable energy the same as GreenPower?
No, GreenPower is not exactly the same as renewable energy, but it is closely related. GreenPower is an Australian government-managed program that allows consumers to buy renewable energy to match their electricity usage. Here’s a breakdown of how it works and how it differs from renewable energy:
What is GreenPower?
GreenPower is a voluntary program where households and businesses can pay extra on their electricity bill to support renewable energy generation. When you sign up for GreenPower, your energy provider buys electricity from accredited renewable sources (like solar, wind, and hydropower) on your behalf.
This supports the renewable energy industry, helping more green energy enter the electricity grid.
How is it different from renewable energy?
- GreenPower is a program. GreenPower is not an energy source itself, but a government-accredited program that ensures your electricity consumption is matched by renewable energy generation. It guarantees that the renewable energy you pay for comes from certified sources.
- Renewable energy is the source. Renewable energy refers to the actual energy generated from renewable sources like wind, solar, and water. Whether or not you participate in GreenPower, renewable energy is produced and fed into the national electricity grid.
While GreenPower supports renewable energy, it’s a program that consumers can join to ensure their electricity usage contributes to renewable energy generation. Renewable energy itself is the clean power generated from sources like wind or solar.
GreenPower helps promote and increase the use of these renewable energy sources by allowing people to choose to pay for greener options.
Is renewable energy the sustainable option?
Yes, renewable energy is widely considered the most sustainable option for generating electricity. Here’s why renewable energy is seen as a sustainable solution:
Unlimited resources
Renewable energy comes from sources that are naturally replenished, like sunlight, wind, and water. Unlike fossil fuels (coal, oil, and natural gas), which are finite and will eventually run out, renewable resources are virtually limitless. If the sun shines and the wind blows, we can continue to generate energy.
Low environmental impact
Renewable energy has a much lower environmental impact compared to non-renewable sources:
- No greenhouse gases. Solar, wind, and hydropower generate electricity without producing harmful carbon dioxide (CO2) emissions, which are a major contributor to climate change.
- Reduced air and water pollution. Unlike coal or gas plants that emit pollutants into the air and water, renewable energy sources are clean, helping to improve public health and reduce ecological damage.
Long-term availability
Renewable energy offers long-term energy security because it relies on sources that are abundant and won’t be depleted over time.
This contrasts with fossil fuels, which are becoming more expensive and difficult to extract as supplies dwindle.
Minimal resource extraction
Extracting fossil fuels (e.g., mining coal, drilling for oil) often leads to significant environmental damage, including habitat destruction, water contamination, and soil erosion.
Renewable energy doesn’t involve such destructive extraction processes, making it more sustainable for the planet.
Energy independence
By adopting renewable energy, countries can reduce their dependence on imported fuels, improving energy security.
This makes renewable energy a more sustainable economic option for the long term, as prices for fossil fuels can fluctuate due to supply and demand issues.
Technological innovation
Renewable energy technologies continue to advance, making them more efficient and cost-effective. As technology improves, the ability to store energy (e.g., with batteries) and manage intermittent sources (like solar or wind) also increases, further enhancing the sustainability of renewable energy systems.
While renewable energy is the most sustainable option, it’s important to note:
- Intermittency. Some renewable sources, like solar and wind, are not always available (the sun doesn’t shine at night, and the wind doesn’t always blow). However, energy storage solutions and a mix of renewable sources can address these challenges.
- Upfront costs. Building renewable energy infrastructure (solar farms, wind turbines) can have high upfront costs, but these are offset by low operational costs over time as the energy is free once the infrastructure is in place.
In terms of long-term sustainability, renewable energy is the most sustainable option available. It provides clean, inexhaustible power with minimal environmental impact, ensuring that future generations can meet their energy needs without depleting the planet’s resources.
