For technology companies, maintaining forward growth and momentum in terms of systems and synergies is a double-edged sword, as energy efficiency is also a critical consideration for those in the tech sector. This is not just in terms of reducing costs but also for minimising environmental impact and improving sustainability, an increasingly important factor for employees, shareholders and customers. Let’s look at some workable strategies.
As technology companies often operate large data centres, office buildings, and manufacturing facilities, they are significant importers, or consumers, of energy. Research published by the UK Parliament earlier this year said that technology and data centres alone accounted for 4-6% of global power usage. In Ireland this year, it was revealed that the country’s heavy data centre footprint meant that it had eclipsed the power usage of the country’s 4.5 million people. The amount of data being output is staggering. Eric Schmidt, former Google chairman noted in a controversial quote in 2010; “There were five Exabytes of information created between the dawn of civilisation and 2003, but that much information is now created every two days.” The knowledge that it brings is hugely beneficial but the human, and machine, power needed to sustain the level of technological momentum is hugely demanding.
By implementing realistic energy-saving strategies, companies can reduce their carbon footprint, enhance their reputation, and contribute to global sustainability goals.
Data centre optimisation
Data centres are the heart of technology companies but also among the most energy-intensive operations. Improving the energy efficiency of data centres is crucial for reducing overall energy consumption. Several strategies can be implemented to achieve this:
- Server virtualisation: Server virtualisation involves running multiple virtual servers on a single physical server, reducing the total number of physical servers required. This not only lowers energy consumption but also reduces cooling needs. Consolidating workloads and decommissioning underutilised servers can lead to significant energy savings.
- Advanced server-cooling techniques: Cooling accounts for a very substantial portion of data centre energy use. Companies can implement more efficient cooling methods, such as free cooling, which uses outside air when temperatures are favourable. Liquid cooling, which directly cools server components with a liquid medium system, can also be more energy-efficient, and sustainable, than traditional air cooling.
- Hot and cold aisle containment: This strategy involves separating hot and cold air flows within the data centre to prevent mixing, which improves cooling efficiency. By containing hot and cold aisles, companies can optimise airflow and reduce the energy needed for cooling.
- Energy-efficient hardware: Investing in energy-efficient servers, storage devices, and networking equipment can lead to long-term energy savings. As technology advances, newer equipment typically consumes less power and offers better performance..
- Regular maintenance and monitoring: Ensuring that data centre equipment is regularly maintained and operating at peak efficiency can prevent energy waste. Implementing energy management software to monitor and optimize energy use in real-time can further enhance efficiency.
Smarter working spaces
Creating smart office environments can significantly reduce energy consumption. By using technology to monitor and control energy use in real-time, companies can optimise energy efficiency throughout their office spaces:
- Automated lighting systems: Smart lighting systems can adjust based on occupancy, daylight availability, and time of day. Installing motion sensors in less frequently used areas, such as conference rooms and restrooms, ensures that lights are only on when needed, reducing unnecessary energy use. This is especially important given the high prevalence of hybrid working and reduced office usage.
- Building Automation Systems (BAS): Implementing a BAS allows for centralised control of lighting, HVAC, and other systems. These systems can be programmed to operate only when needed and adjust settings based on occupancy and weather conditions, improving overall energy efficiency.
- Workplace Design and Natural Lighting: Designing offices to maximise natural light can reduce the need for artificial lighting. Using light-coloured materials and open layouts can help distribute natural light more effectively. Additionally, creating open spaces with good airflow can reduce the need for air conditioning, further saving energy.
Flexible and remote working
Although the sectoral trends in tech have been towards a return to the office, from an energy consumption perspective, encouraging remote work and flexible schedules can have a significant impact on your levels of consumption. By decreasing the need for commuting and reducing office space requirements, companies can significantly. lower their overall energy use:
- Remote work policies: By allowing employees to work from home, companies can reduce the energy needed to operate office spaces, including lighting, heating, cooling, and powering office equipment. This also reduces the energy associated with employee commutes, contributing to lower carbon emissions.
- Flexible working hours: Implementing flexible work hours can help distribute energy usage more evenly throughout the day, avoiding peak energy demand times. This can reduce strain on systems and lower energy costs.
- Downsizing Office Space: If a significant portion of the workforce is remote, companies can,and probably should, consider downsizing their office space, leading to reduced energy consumption for lighting, heating, and cooling. This can also offer cost savings in terms of rent and utilities.
Manufacturing sustainably
For technology companies involved in manufacturing, adopting sustainable and energy-efficient practices in production processes is essential:
- Process optimisation: Streamlining production processes to minimise energy-intensive steps can lead to significant energy savings. This includes optimizing the use of materials, reducing waste, and implementing energy-efficient practices at every stage of production.
- Renewable energy integration: Companies can integrate renewable energy sources, such as solar or wind power, into their manufacturing processes. This not only reduces reliance on fossil fuels but also enhances the company’s sustainability credentials.
- Green supply chains: Collaborating with suppliers who prioritise energy efficiency and sustainability can further reduce the overall energy consumption associated with the company’s products. This includes sourcing materials from suppliers that use renewable energy and sustainable practices.
An energy-engaged workforce
Engaging employees in energy-saving initiatives is crucial for the success of any energy management strategy. By fostering a culture of sustainability, companies can encourage behaviours that contribute to energy efficiency:
- Energy awareness programmes: Educating employees about the importance of energy efficiency and providing practical tips for reducing energy use can lead to positive behavioural changes. This includes simple actions like turning off lights and equipment when not in use, reducing unnecessary printing, and minimising personal energy consumption. Strategies for those working remotely are important too.
- Incentives for energy-saving ideas: Encouraging employees to suggest energy-saving ideas and offering incentives for those that are implemented can create a culture of innovation and sustainability. Recognising and rewarding employees who contribute to energy efficiency can motivate others to follow suit.
Whatever systems and strategies you employ, engaging employees in these initiatives ensures a holistic approach to energy management. The strategy can also have marketing dividends, so make sure you track your successes and don’t be shy about letting stakeholders know what progress you have made. Although initial progress can be costly, inaction is no longer an option, these strategies will be vital in shaping a more sustainable and energy-efficient technology sector.
