How Sustainable Hardware is Powering Ireland’s Tech Future

Ireland is Europe’s digital heartland, where rapid technological growth must now balance with strict environmental commitments. Today, implementing energy-efficient solutions is vital for maintaining the country’s competitive edge and protecting its natural resources. By optimizing power usage and component lifecycles through durability and recycling, local firms are proving that high performance can be environmentally responsible.

The Push for Energy Efficiency in Data Centers

As of early 2026, Ireland hosts 82 operational data centers, with several clusters located in the Dublin region. According to the Central Statistics Office (CSO), these facilities now consume approximately 22% of Ireland’s total metered electricity. This marks a significant milestone, as the energy use of data hubs has officially surpassed that of all urban households in the country combined. Efficient hardware development plays a critical role in this transition by optimizing power usage and extending the lifecycle of electronic components. To address this, operators are moving away from traditional cooling systems toward liquid cooling and advanced airflow management.

The integration of smart sensors and IoT devices allows for real-time monitoring of energy patterns. This data-driven approach ensures that every watt is accounted for. Engineers are implementing several strategies to keep these massive hubs running cleanly:

  • District Heating Integration: The pioneering project in Tallaght now successfully recaptures waste heat from server farms to provide low-carbon heating for the Technical University Dublin (TUD) campus and local public buildings.
  • Uninterruptible Power Supply (UPS) systems equipped with lithium-ion batteries for better storage density and faster response times during grid fluctuations.
  • Advanced power distribution units (PDUs) that minimize transmission loss within the server racks through optimized voltage conversion.
  • High-efficiency voltage regulators that stabilize power flow for sensitive AI-ready processors, reducing heat generation.

Circular Economy and Lifecycle Management

The tech industry is notorious for rapid obsolescence, especially with the surge in AI hardware demands. However, the Irish tech sector is pioneering a “circular” approach to physical assets. Instead of the traditional “take-make-dispose” model, firms are adopting modular designs. This means when a single part fails or becomes outdated, technicians replace only that specific module rather than the entire unit. This practice significantly reduces electronic waste, which remains a critical environmental priority for the EU.

Sustainability starts at the design phase. Local innovators are selecting materials that are easier to recover and reuse. This shift requires a deep understanding of metallurgy and chemical engineering to ensure that performance remains top-tier. Several key factors contribute to this more sustainable lifecycle for enterprise devices:

  1. Standardization of components to allow for cross-brand compatibility and significantly easier repairs in the field.
  2. Implementation of “take-back” programs where manufacturers reclaim old server chassis for professional refurbishment and resale.
  3. Use of biodegradable or highly recyclable polymers in the outer casings of industrial electronics to minimize landfill impact.
  4. Refining the extraction process for rare earth metals found in printed circuit boards to create a closed-loop supply chain.

 

Renewable Integration and Grid Stability

A major part of Ireland’s tech future involves syncing hardware with the renewable energy grid. Ireland is a world leader in wind energy, which supplied approximately 34% of national electricity demand throughout 2025. However, wind is intermittent. Sustainable infrastructure must be “grid-aware,” meaning it can adjust its power intake based on the current supply of green energy. This requires specialized power management firmware and robust electrical components that can handle fluctuations without crashing the system.

Leading facilities in Dublin and Cork are already experimenting with “demand-response” technology. During periods of low wind, these systems automatically throttle non-critical tasks to lower the load on the grid. This level of synchronization is only possible through highly specialized equipment. The following elements are essential for creating this harmony between the tech sector and the environment:

  • Variable speed drives (VSDs) in cooling fans that adjust precisely to the needed thermal load, preventing energy waste.
  • Artificial intelligence controllers that predict peak energy pricing and shift heavy computational workloads to “greener” hours.
  • Solid-state storage devices (SSDs) that consume up to 50% less power during active read/write cycles than traditional spinning drives.

By investing in these advanced physical solutions, Ireland is creating a blueprint for other digital economies. The focus on efficiency, modularity, and grid integration ensures that the tech sector can grow without compromising the planet.

This year has seen a 50% rise in the penetration of Virtual Reality (VR) headsets with 11% of respondents now owning the hardware

This year has seen a continued increase in the ownership of games consoles. The rate of ownership has risen from 34% of respondents in 2020 to 41% in 2022. The penetration of VR headsets has also risen to 11% of respondents in 2022, a new Deloitte study shows.

17% of those respondents between 18- and 24-year-olds own a VR headset, and 57% of the same age group know something about the metaverse.  One of the challenges to the penetration of VR technology is the cost of the hardware. One in four of the respondents found the costs to be prohibitive.

The metaverse

One of the largest developments in the virtual reality space, the metaverse – a digital world in which a person can control an avatar and interact with the avatars of others remains an underdeveloped concept for Irish consumers. The term hit mainstream only 12 months ago and 65% of people have heard of it with 35% at least familiar with what the metaverse is.  However, again the 18–24-year-old category are more aware, with 57% of them knowing something about the metaverse.

John Kehoe Deloitte Partner in Audit and Assurance (Technology, Media and Telecom) said: “The concept of a metaverse has been thrust into mainstream media in the past year, with younger people being more familiar with what it is.

“Interestingly awareness is different between men and women, with 44% of men knowing something about the metaverse compared to 26% of women. There are also significant differences in the age demographics, with 57% of 18-24 year olds knowing something about it, compared to just 19% for 55-64 year olds.”

Consoles make pandemic gains but mobile gaming remains dominant

Following declines in 2019 and 2020 after reaching a peak of 38% in 2018, access to games consoles has peaked again with 41% of respondents confirming access. Two thirds (67%) of adults surveyed play digital games on any device, including their smartphone.

The data on console ownership aligns with recent sales figures for the PlayStation 5 (PS5), which sold 25 million units by the end of September 2022, according to Sony’s official sales numbers. However, a persistent chip shortage has kept the PS5 from matching the sales pace of its predecessor, the PS4, which has gone on to sell over 100 million units and counting.

While Microsoft does not disclose official sales numbers, the tech giant has confirmed that the Xbox Series X|S are the fastest-selling Xbox consoles of all time.

However, mobile gaming still remains the dominant market with one-in-two adults who own a smartphone using it to play video games.

Mr. Kehoe continued: “There has been some significant gaming related acquisitions in the last 12 months, with Microsoft’s acquisition of Activision Blizzard, a leader in game development and interactive entertainment content publisher for $68.6 billion, being the most notable. Activision Blizzard earned over half its Q2 revenue from mobile gaming and related sources. This acquisition is subject to regulatory review by the European Commission, the results of this investigation are due by the middle of March 2023.”

In game currency and purchases

‘Gaming on demand’ subscriptions continue to rise in popularity as nearly half of players now hold a gaming subscription with Playstation Plus/Now (20%) and Xbox Live (15%) the most popular.

One-in-four gamers surveyed have purchased in-game currency with younger age groups particularly interested in this: 47% of respondents in the age group 18-24 purchased in game currency. Season passes (15%) or game extensions (10%) related digital content were the top purchases, with either regular money or in-game currency used.

Daryl Hanberry, Partner and Head of Technology, Media and Telecommunications at Deloitte said: “Even though two-in-three gamers have not spent money on digital content in the last two months, we know that these in-game purchases are driving significant revenue for companies like Activision Blizzard, especially purchases made in mobile games.”

Mr. Hanberry continued: “Microsoft’s acquisition of Activision Blizzard and Sony’s plans for a dedicated PlayStation mobile gaming unit show that more traditional gaming companies are beginning to look towards revenue models that are increasingly driven by in-game purchases. It will be interesting to see if the habits of gamers change in response to this.”
