What are ASX energy shares?
Companies that generate and distribute the energy we rely on to power our devices are known as ASX energy shares. They include companies engaged in the exploration, production, and sale of oil, gas, electricity, and renewable energy projects. Around 117 energy companies are listed on the Australian Securities Exchange, ranging from major producers like Woodside Energy to micro-cap explorers with development-stage assets.
The energy sector is vital to the global economy, supplying the fuel that keeps businesses running. ASX energy companies are involved in activities such as:
- Finding and producing oil and gas for electricity generation and fuel manufacturing, also used as raw materials in the production of many hundreds of goods
- Generating and distributing electricity and natural gas to consumers (both retail and business)
- Contributing to renewable energy generation through manufacturing components used in renewable energy production or operating renewable energy facilities
Australia's energy sector is undergoing one of its most significant structural shifts in decades. Traditionally dominated by oil and gas, fossil fuels still account for more than 90% of Australia's total energy mix. However, the transition is well underway. Renewables now account for 36% of Australia's electricity generation, driven by strong policy commitments1. The government aims to reach a clean electricity target of 82% renewable energy by 2030 and net zero emissions by 2050.
Australia also plays a significant role in global energy markets. LNG exports accounted for 83% of Australia's gas output in the first half of 2025, with demand from Asian trading partners remaining a key driver of sector revenue. For oil and gas producers, LNG demand from Asia continues to grow over the medium term, while for renewable-focused utilities, the pipeline of solar, wind, and battery projects is substantial, with strong government policy and falling technology costs improving project economics.
Traditional energy companies are also responding to the long-term investment potential of the energy transition, with major players like Woodside and Origin Energy investing in hydrogen and other clean energy alternatives.
Why invest in energy?
The production and distribution of energy are crucial to providing the global economy with the power it needs to function. The energy sector and the global economy are so closely intertwined that some economists use the values of oil and gas to gauge the economy's health.
Energy is essential, required for almost every human endeavour, and demand for it will only grow as the global population and level of industrialisation increases. Global energy investment reached more than $3.3 trillion in 2025, with $2.2 trillion flowing into clean energy technologies alone, reflecting the scale of capital committed to the sector.
Australia's energy landscape has evolved significantly over the years, diversifying its energy sources beyond traditional fossil fuels to include renewables like solar, wind, and hydropower. This shift not only aligns with global sustainability goals but also offers potential investors a broader spectrum of choices.
The Australian energy sector encompasses a diverse array of sectors that can allow investors to pursue different goals. There are blue-chip options, growth companies, income opportunities, and high-risk exploration and start-up companies.
Top energy stocks on the ASX
There are 183 ASX companies in the energy sector, ranging from multibillion-dollar producers and distributors to small-cap explorers.
This offers investors a broad range of potential investments to choose from, including investment stocks such as Washington H. Soul Pattinson and Co. Ltd (ASX: SOL). Soul Patts has ties to the energy sector through its significant investment in New Hope Corporation Ltd (ASX: NHC), which has operations spanning coal mining, exploration, and oil.
Here are three top ASX energy stocks ranked by market capitalisation from high to low.
| Company | Description |
| Woodside Energy Group Ltd (ASX: WDS) | Petroleum explorer and producer, and a top 10 global independent energy company |
| Santos Ltd (ASX: STO) | Australia's largest natural gas supplier with a portfolio of LNG and oil assets |
| Ampol Ltd (ASX: ALD) | Integrated energy company primarily involved in the marketing and distribution of petroleum products. |
Woodside Energy Group
Woodside Energy is an Australian petroleum exploration and production company. Established in June 2022 when Woodside and BHP Petroleum merged to create a global energy company, Woodside Energy is a top 10 global independent energy company by hydrocarbon production.
The company has three pillars: oil, gas, and new energy. With more than 35 years of operations in Australia, Woodside Energy's global portfolio now extends to the Gulf of Mexico, Louisiana, and Senegal, among other assets.
For the full year 2025, Woodside reported record production of 198.8 million barrels of oil equivalent, exceeding guidance. Net profit after tax (NPAT) came in at US$2.7 billion, with softer commodity prices weighing on earnings despite the production milestone. The company paid a fully franked full-year dividend of US$1.12 per share, maintaining its payout ratio at the top of its target range.
On the growth front, the Scarborough LNG project in Western Australia is targeting its first LNG cargo in Q4 2026, while the US$17.5 billion Louisiana LNG project is progressing toward first production in 2029. Woodside has also taken operational control of its Beaumont New Ammonia facility in Texas, marking a significant step in its new energy strategy.
Santos
Santos is a natural gas supplier. Already Australia's biggest domestic gas supplier, Santos aims to be a leading Asia-Pacific LNG supplier. With a portfolio of LNG and oil assets, Santos has core assets located across Australia, Papua New Guinea, Timor-Leste, and Alaska.
Locations include the Cooper Basin, where Santos operates Australia's largest onshore oil and gas field development spanning South Australia and Queensland, and the Carnarvon Basin in Western Australia. For the full year 2025, Santos reported an underlying net profit after tax (NPAT) of US$898 million, with sales revenue of US$4.9 billion and strong free cash flow generation of US$1.8 billion. The company paid a respectable 4.0% dividend yield.
Two major growth projects are reshaping Santos' portfolio. The Barossa gas field began supplying Darwin LNG in early 2026, with the first LNG cargo delivered to Japan, restarting a facility that had been idle since late 2023. The Pikka oil project in Alaska also achieved first oil in early 2026, with both projects expected to drive a 25–30% increase in production by 2027.
Santos has also embraced decarbonisation through Santos Energy Solutions, which includes the Moomba carbon capture and storage (CCS) project in South Australia, which stored more than 1.5 million tonnes of CO2 equivalent in its first year of operations.
Ampol
Ampol (formerly known as Caltex Australia Limited) is involved in the wholesale, commercial, and retail supply of fuel products, including petrol, diesel, and gasoline. It has the Lytton refinery in Queensland that processes crude oil into various petroleum products. Ampol also produces and distributes lubricants under various brands, catering to automotive, industrial, and commercial applications.
Ampol delivered a strong full-year 2025 result, with RCOP NPAT of $429 million, up 83% on the prior year. The standout driver was a rebound at the Lytton refinery, which returned to profitability after a weak 2024, while the Convenience Retail segment also grew earnings. The company paid total fully franked dividends of $1.00 per share for the year.
The company continues to pursue a strategy of building a more resilient business through non-fuel and international earnings growth. Z Energy, the New Zealand transport fuel business acquired in 2022, delivered EBIT of $234 million and remains a core part of the international portfolio.
Ampol is also progressing a proposed acquisition of EG Australia, with completion expected mid-2026 subject to regulatory approval, which would further expand its convenience retail network. An Ultra Low Sulfur Fuels upgrade at the Lytton refinery is expected to begin commissioning in the second quarter of 2026, positioning the refinery to meet tightening domestic fuel standards.
Pros of investing in ASX energy shares
Vital service: ASX energy companies provide the electricity used to power homes and businesses and the fuels used to power transport. They play a vital role in the functioning of the economy.
Growing demand: Energy consumption has increased exponentially since the 1950s and shows no sign of slowing down.3 Demand grows across many countries as people get richer and populations increase.
Commitment to reducing emissions. The commitment to reducing emissions has gained momentum, meaning there is a shift away from traditional power generation methods and a move towards electrification and renewables.
And the disadvantages…
Volatility: Geopolitical tensions can cause the oil price and the prices of gas and electricity to skyrocket. This means energy shares can be volatile, as we have seen over the past year.
Geopolitical risk: Geopolitical tensions can affect more than the price. They can result in entire projects being sidelined or halted where the territory is unstable.
Profitability: Profitability in the energy sector is tied largely to the price of energy and inputs such as coal and oil. Nonetheless, the price of energy shares is typically relatively stable, and energy companies frequently pay dividends.
Are ASX energy stocks a good investment?
The wide variety of Australian shares in the energy sector means there are options to suit most investors. Those interested in new technology and the transition to green energy may choose renewable energy stocks.
For investors with a high-risk appetite, small-cap exploration companies may be attractive. Large-cap energy producers may fit the bill if you are after dividends. The energy stock that is right for you is the one that fits your investment strategy and financial situation.
For those who want exposure to the sector as a whole, an exchange-traded fund (ETF) such as the Betashares Global Energy Companies ETF (ASX: FUEL) might be suitable.
The ASX energy sector has had a mixed recent run. The S&P/ASX 200 Energy Index (XEJ) delivered a positive total return of 3.2% in 2025, with a dividend yield of 5.46% offsetting a small capital decline, following a much tougher 2024. In early 2026, geopolitical tensions in the Middle East pushed oil prices sharply higher, triggering a strong rally in major producers before partially reversing. Analysts are now forecasting earnings growth of around 14% for the oil and gas sector in 2026, reflecting expectations of a recovery from recent earnings weakness.
Ultimately, whether ASX energy shares are right for you will depend on your investment goals, risk tolerance, and financial situation. Take the time to research the energy companies you are interested in to ensure they fit your financial objectives. Stay on top of market news and seek expert financial advice if required to make your investment decision.
