Australia, a land of sunshine and vast landscapes, is also at the forefront of the renewable energy revolution. With ambitious goals to reduce carbon emissions and transition to a clean energy future, Aussies increasingly seek green energy providers who align with their values. But with so many options available, choosing the most green energy provider can be overwhelming.
The shift is accelerating fast: Australia’s on-grid electricity reached 42.0% renewables in 2025, and renewable energy accounted for 43.7% of National Electricity Market generation in 2025, exceeding 50% in the December quarter of 2025 for the first time. That momentum makes choosing a genuinely green retailer more meaningful — and more confusing — than ever, because not every retailer marketing “green” plans is genuinely low-carbon.
Key Takeaways
- Environmentally friendly energy companies prioritise clean sources like solar, wind and hydro, and often hold independent accreditation such as GreenPower.
- GreenPower is the government-managed accreditation scheme; its 2024 audit recorded 37 accredited providers, 59 products and 183,912 customers.
- Rankings and scores change frequently — always verify a provider’s current renewable percentage and accreditation before switching.
- Look beyond marketing: check third-party sources such as GreenPower, the Clean Energy Council and the Greenpeace Green Electricity Guide.
- Pairing a green retailer with rooftop solar and a battery delivers the biggest emissions and cost impact.
- Watch for greenwashing — a “carbon neutral” claim is not the same as sourcing 100% renewable electricity.

What are environmentally friendly energy companies?
Environmentally friendly energy companies are electricity retailers that source most or all of their power from renewable generation, hold independent green accreditation like GreenPower, and actively invest in reducing emissions rather than only offsetting them. Also known as “green energy providers”, “sustainable energy providers” or “renewable energy companies in Australia”, they prioritise clean and sustainable energy sources like solar, wind, hydro, and geothermal power. They strive to minimise their environmental footprint through various practices, such as:
Investing in renewable energy generation: This could involve building and operating solar and wind farms, investing in existing renewable energy projects, or sourcing electricity from renewable sources on the grid.
Promoting energy efficiency: These green energy companies often offer resources and incentives to help customers reduce their energy consumption, lowering their carbon footprint and energy bills.
Transparency and ethical business practices: Many green energy providers prioritise transparency in their energy sourcing and pricing, and some even support community initiatives or environmental causes.
Green credentials explained: GreenPower, Climate Active and NETCC
Not all “green” claims are equal, so it helps to understand the labels:
- GreenPower — a government-managed program where retailers buy accredited renewable energy on your behalf, over and above the grid mix. GreenPower states that almost all electricity retailers in Australia have a GreenPower-accredited product, and its live provider finder lets users filter current offers by state or territory.
- Climate Active — a certification for carbon-neutral products or organisations, which may rely on offsets rather than 100% renewable sourcing.
- NETCC (New Energy Tech Consumer Code) — a Clean Energy Council-administered code covering fair sales and service for solar and battery products.
Why choose an environmentally friendly energy company?
Switching to a green retailer directly cuts the carbon intensity of your household electricity, supports new renewable projects, and can unlock savings through solar feed-in tariffs and battery incentives. There are many compelling reasons to switch to an environmentally friendly energy company:
Reduce your carbon footprint: By choosing renewable energy, you’re directly contributing to the fight against climate change and reducing your personal carbon footprint.
Support sustainable development: You promote developing and adopting clean energy technologies, creating a more sustainable future for future generations.
Enjoy potential cost savings: Many renewable energy providers offer competitive rates, and you may even be eligible for government incentives like feed-in tariffs for solar power.
Peace of mind: Knowing your energy comes from clean sources provides peace of mind and aligns with your values.
The upside is amplified when you pair a green plan with your own generation and storage. Across the NEM, the share of residential customers with solar panels increased from about 27% to nearly 30% between 2023-24 and 2024-25, and at least 402,700 batteries were installed Australia-wide between 1 July 2025 and 17 May 2026 under the Cheaper Home Batteries Program. For more on how this fits the bigger picture, see how renewable energy is powering Australia’s journey to net-zero emissions.
How to choose an environmentally friendly energy company in Australia
To choose a genuinely green energy company, check the retailer’s renewable percentage, confirm current GreenPower accreditation, review transparency around emissions, and compare pricing and service — then verify against independent sources rather than marketing claims. Here are some key factors to consider when choosing a green energy provider:
Renewable energy source: Look for companies that source their electricity primarily from solar, wind, and hydro.
Transparency and ethics: Choose companies that are transparent about their energy mix, environmental practices, and community engagement.
Customer service and pricing: Compare customer service ratings, pricing plans, and available features like smart meters and battery storage options.
Green accreditation: Look for companies accredited by organisations like the Clean Energy Council or certified by the Green Electricity Guide.
Be alert to greenwashing, where a retailer’s marketing overstates its environmental credentials. A “carbon neutral” badge based on offsets is not the same as buying accredited renewable electricity. Our guide on greenwashing in energy and how to spot real vs. fake claims breaks down the warning signs.
How we assess green energy providers
Rather than relying on a single fixed score, we recommend cross-referencing four authoritative signals: GreenPower accreditation status (managed by the Australian, state and territory governments), the Greenpeace Green Electricity Guide ranking, the Clean Energy Council’s certifications, and each retailer’s published renewable energy mix. Because market conditions and product offers change frequently, always confirm the latest details directly with the provider before switching.

As a 2026-safe benchmark, retailer-specific Virtual Power Plant (VPP) incentives should not be treated as evergreen: the regulator-backed Solar Sharer Offer provides free daytime usage windows of 11am–2pm in NSW and SE Queensland and 12pm–3pm in South Australia, while 2026-27 residential comparison prices range from $1,893 to $2,530 depending on distributor. For NSW, the 2026-27 all-day solar feed-in tariff benchmark is 3.4–6.5 c/kWh from 1 July 2026 to 30 June 2027, so any higher rate should be viewed as a conditional premium offer rather than a baseline.

Beyond the big names: Unearthing hidden gems
Smaller regional and community-owned retailers often deliver outstanding environmental value by investing directly in local renewable projects — so it pays to research options in your area, not just the national brands. While the companies above are stellar, don’t overlook smaller, regional providers doing incredible work. Prioritise those with strong community ties and a focus on local renewable energy generation. Remember, every switch to a green provider makes a collective impact!
Community energy is also feeding directly into the grid transition. As of January 2026, 63,100 customers with installed batteries were participating in virtual power plants — around 24% of the 262,400 battery customers identified by the ACCC, showing how household storage is becoming part of a cleaner, more flexible system.
