What makes tech sustainable, truly?
Many products claim to be “green,” but true sustainability in IoT devices goes beyond energy savings alone. A genuinely sustainable IoT solution must incorporate:
- Low power consumption: Devices designed with ultra-low-power components and energy-harvesting capabilities. For example, Amazon’s Kindle e-readers use E-Ink technology, which consumes power only when changing pages, significantly reducing energy usage compared to traditional LCD or OLED screens. Some models can last weeks on a single charge, making them a prime example of ultra-low-power components in action.
- Longevity and durability: Hardware that is built to last reduces e-waste. For example, the Fairphone 4 is designed to be modular and repairable, extending its lifespan well beyond typical smartphones. Users can easily replace components like the battery, screen, and camera, reducing e-waste while maintaining performance over time.
- Smart power management: Dynamic power scaling and adaptive energy usage. For example, The Tesla Powerwall is a smart home battery that dynamically manages energy by storing solar power during the day and supplying energy at night. It optimises power distribution based on energy demand, peak hours, and grid availability, reducing reliance on non-renewable electricity sources.
- End-of-life viability: Can the device be refurbished, repurposed, or recycled? For example, Dell’s Latitude 5000 series laptops are designed for easy disassembly and recycling. The company offers Product Life Cycle Support, which consists of a ‘take-back’ program allowing users to return old laptops for responsible refurbishment, parts harvesting, or recycling, minimising landfill waste.
- Supply chain transparency: Ethical sourcing of materials and responsible manufacturing practices. For example, Apple has committed to using 100% recycled rare earth elements in products like the iPhone 12 and later models. It also publishes a Supplier Responsibility Report, ensuring ethical sourcing of materials like aluminium, tin, and cobalt while reducing reliance on conflict minerals.
By focusing on these principles, businesses can avoid greenwashing (i.e., intentionally giving the impression that a product or service is more eco-friendly than it is) and implement truly energy-efficient IoT systems that deliver measurable benefits.
How is sustainability in the tech industry measured?
Sustainability in the tech industry differs from other sectors such as manufacturing, food and beverage, or retail, where practices like local or organic sourcing, seasonal production, biodegradable packaging or low-carbon logistics define eco-friendliness. Instead, tech sustainability is often measured through specific metrics, including:
- Energy efficiency ratings: The amount of power consumed per task, often measured in watts per gigabyte for data centres or milliwatts per operation for IoT devices.
- Carbon footprint: The total greenhouse gas emissions from device production, usage, and disposal.
- Lifecycle Assessment (LCA): A comprehensive analysis of a product’s environmental impact from raw material extraction to end-of-life.
- E-waste reduction metrics include the percentage of materials that can be reused or recycled and the longevity of hardware before replacement.
- Renewable energy use: The proportion of renewable energy used in production and operation.
- Water and resource usage: The amount of water and other resources consumed in manufacturing.
By leveraging these metrics, companies can decide which IoT solutions offer genuine sustainability benefits rather than just marketing claims.
Resource-efficient strategies enabled by energy-efficient IoT
Sustainability managers, product developers, and householders alike can use IoT to implement energy-saving strategies and green IoT (GIoT) practices that lead to cost reductions and environmental benefits. Some key areas include:
- Smart Grid Integration: IoT sensors enable demand-response systems that optimise energy distribution, reducing waste.
- Predictive Maintenance: IoT-powered maintenance and building management schedules prevent equipment failures, extend operational life, and reduce energy waste.
- Automated Lighting & HVAC Control: Smart buildings and homes adjust energy use in real time, reducing electricity consumption.
- Water & Waste Management: IoT-enabled leak detection and waste tracking improve efficiency in resource utilisation.
These strategies are not just theoretical; they are already being implemented across various industries to drive sustainability goals. Contact us for cost-efficient, effective, and sustainable solutions that are scalable and adaptable.
The Role of IoT in Energy Saving
So, how much energy can energy-efficient IoT actually save? Studies indicate that IoT-enabled systems can reduce energy consumption by up to 30% in commercial buildings and 20-50% in industrial applications. For example:
- Manufacturing: Smart sensors detect inefficiencies in production lines, reducing wasted electricity and water.
- Retail: Energy-efficient IoT-enabled refrigeration systems in supermarkets optimise cooling cycles, cutting down excess power usage.
- Logistics: IoT-powered fleet management minimises fuel consumption through optimised route planning and predictive vehicle maintenance.
These real-world applications showcase how energy-efficient IoT devices don’t just cut costs—they drive meaningful environmental change.
Promoting a Circular Economy in IoT
One of the most impactful ways to ensure sustainability in IoT is by adopting a circular economy approach. Unlike the traditional linear “produce > use > dispose” model, a circular economy focuses on designing products for longevity, repairability, and recyclability. Key strategies include:
- Modular Design: IoT devices should be built with replaceable parts, allowing for upgrades instead of full replacements.
- Repairability: Devices should be easy to fix rather than discarded due to minor failures.
- Material Recovery: Manufacturers should prioritise recyclable materials to reduce e-waste.
- Responsible Disposal & Take-Back Programs: Companies can implement take-back initiatives, ensuring proper recycling or repurposing of outdated IoT devices.
By integrating these principles, energy-efficient IoT solutions can become genuinely sustainable, minimising their long-term environmental impact.

What’s next for sustainable IoT innovation?
To ensure that IoT sustainability moves beyond its current capabilities, innovators must address key challenges:
- End-of-Life Viability: Can IoT devices be easily repaired, upgraded, or recycled? Many contain non-recyclable components, making disposal a sustainability challenge.
- Material Innovation: The industry must move toward biodegradable, recyclable, or ethically sourced materials.
- Energy Harvesting Technologies: Future IoT devices should incorporate solar, kinetic, or thermal energy harvesting to minimise reliance on traditional power sources.
