Every photo you back up and every show you stream runs through a building full of servers. AEMO’s 2026 forecasting overview says around 165 data centres used about 5 terawatt-hours in FY26, roughly 3% of the National Electricity Market. That is the heart of Australia’s internet and cloud storage carbon footprint, and it is growing fast.
So, is your cloud storage renewable? Sometimes, but not always in real time. This guide covers the numbers, what they mean for your bills, and how home solar can offset your digital carbon footprint. Get a free quote from Energy Matters today and put your own roof to work.
Quick answer
- Data centre strain: Australia’s data centres and cloud servers draw billions of kilowatt-hours from the main grid, driving up power demand across eastern states.
- Hidden carbon footprint: Storing files, streaming high-definition media, and sending emails create a significant digital carbon footprint in Australia every day.

What is the carbon footprint of internet cloud storage in Australia and why should Australian homeowners care?
When you save a photograph to iCloud, Google Drive, OneDrive or another cloud service, the file does not disappear into an invisible digital space. It is stored on physical equipment inside a data centre, backed up across systems and accessed through networks that all require electricity.
The cloud storage carbon footprint therefore depends on much more than the size of a file. It can include data centre electricity, cooling, networking, backup systems, hardware manufacturing and the carbon intensity of the electricity supplying those facilities. Use Energy Matters’ carbon footprint calculator to estimate your household and business’s direct emissions.
The key facts
The internet is not weightless. It is a physical system of data centres, undersea cables, mobile towers, home routers and screens, and every part of it runs on electricity. Internet emissions in Australia depend on how that electricity is generated.
Globally, the International Energy Agency (IEA) estimates data centres used about 415 TWh in 2024, around 1.5% of world electricity. Australia’s share is smaller, but it is rising quickly.
| Measure | Figure | Source |
| Australian data centre use, FY26 | About 5 TWh (around 3% of NEM consumption) | AEMO |
| Forecast for FY30 | About 15 TWh (7.8% of NEM) | AEMO |
| Forecast for FY36 | About 34 TWh (13% of NEM) | AEMO |
| Global data centre use, 2024 | About 415 TWh (1.5% of world electricity) | IEA |

Why carbon footprint internet cloud storage matters right now in Australia
The scale of Australia’s data centre expansion has moved the issue beyond an environmental niche. AEMO says Australia had 162 operational data centres nationally in 2026, with 11 large projects representing 5.4 GW of potential maximum demand progressing through the transmission connection process at the end of March.
New data centre developments are also becoming a policy issue. NSW introduced a Data Centre Policy Framework in 2026 that calls for additional energy and water infrastructure and environmental performance standards, while Victoria announced new requirements for data centres to bring renewable energy supply and storage.
Expert insight: Energy Matters says Australians should not think of the internet as weightless infrastructure. Digital services rely on a rapidly expanding physical energy system, and the transition to renewable electricity is becoming increasingly important as digital demand grows.
How the carbon footprint of internet cloud storage works in Australia
The carbon footprint of internet cloud storage users in Australia spans several stages. Understanding those stages makes it easier to see where you can reduce emissions.
Technical explanation
Think of cloud storage as a chain:
- Your device creates or accesses data. Your phone, laptop or television consumes electricity.
- The data travels through networks. Mobile networks, Wi-Fi equipment, fibre networks and routers all require power.
- A data centre stores or processes the information. Servers, storage drives, cooling systems and backup equipment consume electricity.
- The data may be copied or backed up. Cloud providers commonly maintain redundancy to protect information.
- Hardware has an embodied footprint. Manufacturing servers, storage equipment, networking hardware and buildings requires energy and materials.
- Electricity generation determines much of the operational footprint. A data centre supplied predominantly by renewable electricity generally has a lower operational carbon footprint than one relying heavily on fossil-fuel generation.
A data centre’s electricity demand is not simply the power consumed by computer chips. Cooling, power conversion, storage and networking infrastructure also contribute.
Globally, the IEA estimates data centres consumed around 415 TWh of electricity in 2024, approximately 1.5% of global electricity consumption. Global data centre electricity demand then increased another 17% in 2025.
Australian examples and data
Australia is entering this global trend with particularly strong growth. AEMO’s 2026 analysis identifies data centres as one of the fastest-growing sources of electricity demand across the NEM and Western Australia’s WEM.
AEMO’s latest Electricity Statement of Opportunities forecasts NEM data centre consumption to rise from approximately 5 TWh in 2025-26 to 34 TWh in 2035-36. That would increase their share of grid-supplied electricity from around 3% to about 13%.
This does not mean that every Australian household’s cloud storage has a fixed carbon figure. The emissions attached to a gigabyte of storage vary by provider, location, energy source, utilisation, equipment efficiency, and how frequently data is accessed.
That uncertainty is important when considering claims about a specific cloud storage carbon footprint.
What does this mean for your electricity bills?
Your personal cloud storage usually doesn’t appear as a separate line item on your electricity bill. The connection is indirect, but it can become increasingly important as large digital loads compete for electricity supply.
Short-term impact
For an individual household, deleting old emails or reducing cloud photo storage is unlikely to noticeably change a quarterly electricity bill. The more immediate household opportunity is controlling the electricity you directly purchase.
That includes appliances, heating and cooling, hot water, electric vehicles, home batteries and other major loads.
However, rapid growth in large electricity users can influence the broader energy system. AEMO has identified data centres as an increasingly important component of future demand forecasting, while the Australian Government is investing in generation, storage and transmission to support a more electrified economy.
Long-term implications
The long-term question is whether digital growth is matched by new clean generation and network capacity.
AEMO forecasts total operational electricity consumption to increase substantially over the next decade, with data centres, electrification and other new loads contributing to demand growth.
If renewable generation and storage meet new demand, the internet emissions Australia debate could increasingly become an energy-transition success story. If demand growth outpaces clean generation, additional fossil-fuel generation could increase pressure on emissions and wholesale electricity markets.
The Australian Government’s 2025 emissions projections anticipate electricity sector emissions falling by more than 60% between 2025 and 2030, supported by renewable energy policies and initiatives including the Capacity Investment Scheme, Rewiring the Nation and the Cheaper Home Batteries Program.
Expert insight: Investing in rooftop solar and a home battery effectively caps your energy expenses while offsetting the unseen environmental impact of your family’s connected devices.
What Australian homeowners can do right now?
You cannot personally control the electricity mix of every server storing your photographs. You can, however, reduce unnecessary digital demand and make your household electricity supply cleaner.
Actionable steps
1. Use cloud storage intentionally
Delete duplicate videos, unwanted backups and files you no longer need. This will not transform Australia’s emissions profile, but it is a sensible part of responsible digital consumption.
2. Keep devices for longer
The digital carbon conversation in Australia should include manufacturing, not just electricity consumption. Extending the useful life of phones, laptops, tablets and televisions can reduce the need for new hardware.
3. Choose lower-energy devices
An efficient laptop can consume considerably less electricity than a large television during everyday use. The IEA has also highlighted that device electricity use can be a major component of streaming’s overall energy demand.
4. Avoid unnecessary streaming
Streaming energy use is generally small compared with major household energy loads, but unnecessary hours add up across millions of users. Use downloads when practical, avoid autoplay and switch devices off when nobody is watching.
5. Review your email habits
The email carbon footprint of one ordinary message is relatively small, particularly compared with major household energy uses. However, unnecessary attachments, mass mailings and storing large volumes of redundant material contribute to wider digital resource demand.
6. Generate renewable electricity at home
This is the bigger household action. Rooftop solar can reduce the amount of electricity your home needs from the grid, while a battery can store daytime solar generation for later use.
The Australian Government’s Cheaper Home Batteries Program has provided a discount of around 30% for eligible small-scale battery systems installed from 1 July 2025.
7. Shift flexible electricity use
Where practical, use solar-generated electricity during the day for appliances, hot water, EV charging and other flexible loads. This can increase your direct use of renewable energy.
Powering up your EV with solar
If you’re thinking of buying an EV, adding an EV charger to your solar system is a smart way to “fuel” your car with clean, renewable energy.
Questions to ask your installer or retailer
Before investing in solar or batteries, ask:
- What proportion of my household electricity use can solar realistically cover?
- Would a battery improve my self-consumption?
- What battery size suits my actual electricity profile?
- Is the system eligible for current federal or state incentives?
- Is the inverter and battery system CEC-approved where required?
- Can the system participate in a Virtual Power Plant?
- What happens during a blackout?
- What are the expected annual savings, and what assumptions support them?
- What monitoring data will I receive?
- How will the system perform during summer heatwaves?
The Australian Government’s Solar Consumer Guide recommends comparing system design, expected performance, costs, warranties and installer credentials before signing a contract.
State-by-state considerations: VIC, NSW, QLD, SA and WA
Electricity carbon intensity and available household incentives vary by state. That means the most practical response to the carbon footprint of internet cloud storage in Australia can differ depending on where you live.
| State | 2026 consideration | What households should know |
| Victoria (VIC) | Strong focus on renewable-powered data centres | Victoria announced requirements for new data centres to provide their own renewable energy supply and storage. Eligible households can also access Victorian solar incentives. |
| New South Wales (NSW) | Rapid data centre growth and battery incentives | NSW has introduced a Data Centre Policy Framework, and its Home Energy Saver program offers eligible households interest-free loans of up to $15,000 for energy upgrades. |
| Queensland (QLD) | Major data centre growth and ongoing energy transition | Queensland’s previous Battery Booster rebate has closed. Households should check current federal support and available retailer or network programs before purchasing. |
| South Australia (SA) | High renewable penetration and Virtual Power Plant (VPP) participation | South Australia’s VPP continues to coordinate solar and home batteries, helping households participate in a more flexible electricity system. |
| Western Australia (WA) | Separate grid and major battery incentives | WA’s Residential Battery Scheme offers rebates of up to $1,300 for Synergy customers and $3,800 for Horizon Power customers, alongside federal support. VPP participation is required. |
Western Australia also introduced updated technical requirements for new and upgraded rooftop solar and battery systems from 1 May 2026. The changes are intended to support larger systems and future grid participation.
For NSW homeowners, the state’s 2026 Home Energy Saver program is particularly relevant, with zero-interest loans of up to $15,000 for eligible energy upgrades and targeted discounts of up to $4,000 planned for eligible households.
Expert insight: State policies increasingly recognise that household solar and batteries are not simply bill-saving technologies. They can also provide flexible capacity that helps the wider electricity system absorb new demand from electrification and digital infrastructure.
Expert predictions for 2027 and beyond
The biggest change will be the scale of electricity demand from digital infrastructure.
AEMO’s 2026 ESOO puts NEM data centre consumption on a trajectory from about 5 TWh in 2025-26 to 34 TWh in 2035-36. That is a major shift in the electricity market and one that will make the renewable supply of digital services increasingly important.
Three developments are likely to shape the next phase.
1. Data centres will become a major electricity customer
AI, cloud computing and digital services are driving investment in increasingly power-intensive facilities. AEMO says the sector is already becoming one of the fastest-growing sources of electricity demand.
2. Renewable power will become a competitive advantage
The debate is moving from whether data centres should consume electricity to how that electricity should be supplied.
In 2026, NSW introduced expectations that data centre investment should be matched with additional renewable energy and infrastructure. Victoria went further by announcing requirements for new data centres to bring renewable energy supply and storage.
3. Batteries and flexible demand will matter more
As electricity demand rises, batteries can help shift renewable energy from periods of high solar production to periods of higher demand.
This matters at both the grid and household scales. A home battery cannot directly power a remote cloud server, but thousands of coordinated household batteries can contribute flexibility to the electricity system through programs such as Virtual Power Plants.
Expert insight: The biggest opportunity is not asking Australians to stop using cloud services. It is building an electricity system where rising digital demand is increasingly supplied by renewable generation, batteries, transmission and smarter demand management.
Frequently asked questions
Is cloud storage renewable?
Cloud storage itself is not renewable because it is a digital service supported by physical servers, buildings, cooling systems and networks. Its carbon footprint depends partly on the electricity those facilities use. Cloud services can have a lower operational footprint when their electricity supply increasingly comes from renewable generation.
Does storing photos in the cloud create carbon emissions?
Yes, indirectly. Cloud photographs require physical storage, backup infrastructure, networking and electricity. However, the footprint of an individual photograph is difficult to calculate accurately because it depends on storage efficiency, duplication, data centre efficiency, electricity sources and how frequently the file is accessed.
What has the biggest digital carbon footprint at home?
The answer varies by household. Large-screen televisions, computers, networking equipment and other devices can contribute substantially to electricity use, while data centres and networks support the services being used. Streaming research has found that the viewing device can account for a significant share of total energy use.
Does deleting emails reduce my carbon footprint?
Deleting unnecessary emails can reduce the amount of data that needs to be stored, but the direct emissions savings for an individual household are likely to be very small. Bigger opportunities include reducing unnecessary device use, extending hardware lifespans and lowering household grid electricity consumption with energy efficiency, solar and batteries.
Can rooftop solar offset my internet emissions?
Rooftop solar cannot directly assign renewable electricity to every cloud service you use. It can, however, reduce the fossil-fuel-derived electricity your household purchases from the grid, lowering your home’s operational emissions and supporting Australia’s broader transition to renewable electricity.
Key takeaways
