How Our eSIM Business Uses Solar Energy to Reduce Carbon Emissions
AirSims.com.au Uses Solar Energy and Energy Saving methods to Reduce Carbon Emissions 🍃
At our core, we believe connectivity shouldn’t come at the planet’s expense. As an eSIM provider based in Melbourne, Australia, we’ve taken meaningful steps to reduce our environmental footprint - including powering our operations with an 8kW solar system along with Energy Saving Hardware.
List of what we do:
- 8KW Solar System and we export excess power to the grid.
- Nano-Ceramic Tinted Windows
- Alloy Shutters
- Low powered LED lighting
- Insulation
- Draught sealed doors and windows
Why Digital Connectivity Still Has a Carbon Footprint
While eSIM technology eliminates the need for physical SIM cards, packaging, and shipping, digital services still rely on energy - from servers and networks to day-to-day business operations. That energy often comes from carbon-intensive sources.
💡 Did you know? A mobile app on average contributes around ~200kg (weight of an average lion) of additional CO₂ yearly per 10,000 users? AirSims being app-less means we effectively prevent this extra CO₂ even if we didn't have solar!
This is where renewable energy plays a critical role.
Our Solar Setup: 8kW of Clean Energy
Our Melbourne-based operations are supported by an 8kW solar power system. On average, solar systems of this size in Victoria generate approximately 30–35 kWh of electricity per day, depending on the season.
That’s clean, renewable energy replacing electricity that would otherwise fully come from fossil fuels.
Understanding the Carbon Offset
In Australia, grid electricity produces roughly 0.7 kg of CO₂ per kWh. By generating our own solar power, we help reduce these emissions.
| Metric | Estimated Value |
|---|---|
| System Size | 8 kW |
| Average Daily Generation | 32 kWh/day |
| Annual Generation | 11,680 kWh/year |
| CO₂ per kWh (AU avg.) | 0.7 kg CO₂ |
| Annual CO₂ Offset | 8,176 kg CO₂ (~8.2 tonnes) |
The Hidden Energy Cost of Connectivity
Every mobile connection - whether physical SIM or eSIM - relies on a global network of data centres, authentication servers, and telecom infrastructure. These systems require continuous computing power to:
- Authenticate users on mobile networks
- Manage provisioning and activation
- Handle billing and usage tracking
- Store and process customer data securely
How eSIM Technology Reduces Computing and Energy Demand
eSIM doesn’t just remove plastic - it streamlines the entire lifecycle of a mobile connection.
Traditional SIM cards require manufacturing systems, global logistics tracking, warehouse management software, and retail activation infrastructure. Each of these layers adds additional computing load and energy usage.
With eSIM, everything becomes digital and on-demand:
- No manufacturing resource planning systems for plastic SIM production
- No shipping logistics platforms or tracking servers
- No retail activation terminals or point-of-sale infrastructure
Estimated Computing & Energy Savings
While exact figures vary across the telecom industry, we can illustrate the difference with a simplified comparison per 10,000 customers:
| Process | Traditional SIM | eSIM |
|---|---|---|
| Manufacturing Systems | High | None |
| Logistics & Shipping | High | None |
| Retail Activation Systems | Moderate (Retail Shop + Cloud) | Very Minimal (Resides in the Cloud) |
| Cloud Provisioning (Data Centres) | Moderate | Moderate |
| Total Energy Use | 100% | ~60–70% |
In simple terms, eSIM can reduce the overall computing and infrastructure energy footprint by an estimated 30–40% compared to traditional SIM distribution models.
How Our Solar Further Offsets This Usage
The remaining digital infrastructure - such as provisioning servers and customer systems still requires energy. This is where our solar setup plays a key role.
With approximately 11,680 kWh generated annually, our solar system can support:
- Hundreds of thousands of eSIM activations
- Continuous operation of cloud-based systems
- Customer support and backend platforms
Put into non-IT perspective:
- Taking 2–3 cars off the road for a year 🚗
- Planting over 120 trees and letting them grow for a decade 🌳
- Avoiding thousands of kilometres of fossil-fuel-powered travel 🛣️
By powering these systems with renewable energy, we significantly reduce the carbon intensity of every connection we provide.
Why eSIM + Solar Is a Powerful Combination
eSIM technology reduces physical waste and system complexity, while solar energy reduces the emissions from the infrastructure that remains.
Together, they create a more efficient, lower-impact model for global connectivity.
Our Ongoing Commitment
Sustainability isn’t a one-time effort. We’re continuously looking for ways to:
- Improve energy efficiency across our systems
- Work with greener infrastructure providers
- Educate customers about lower-impact connectivity choices
- 🏆 Bonus are lower power bills, which means savings to you - Our customers.
Every connection you make with us is powered more cleanly - and that’s something we’re proud of.
Final Thoughts
The future of connectivity is digital, but it must also be sustainable. By combining eSIM technology with renewable energy, we’re helping build a lower-carbon future - one connection at a time.
