Global energy systems are moving closer towards more sustainable practices. As a result, the role of the telecoms sector now extends beyond simple connectivity. Ever-increasing energy consumption and the need to meet decarbonisation targets are putting pressure on telecoms companies to use energy more efficiently.
According to a recent report from BCG, the telecoms industry currently accounts for around 2% of the global CO2 footprint. By 2040, this figure is expected to increase to 14% [1].
However, there is hope. The World Broadband Association has found that telecoms service providers could have an impact on up to 15% of global CO2 emissions by implementing sustainable practices [2].
Let’s take a closer look at the role of telecoms in the energy transition:
The goals of the energy transition
The energy transition is a term used to refer to the global shift from traditional energy sources, like coal and oil, to sustainable sources like wind, solar or hydropower.
The aim of the energy transition is to mitigate climate change, mainly by reducing greenhouse gas emissions, which are the biggest contributors to global warming. The energy transition also seeks to minimise environmental degradation, improve air quality and protect ecosystems.
Another goal of the energy transition is to increase energy security by diversifying energy sources and reducing our dependence on finite fossil fuels. This shift hopes to deliver greater resilience against both supply disruptions and price volatility. In turn, this will ensure more stable and reliable access to energy.
The energy footprint of the telecoms industry
The telecommunications sector is vital for modern society. It allows us to stay connected and communicate on a global scale. However, it is also a significant consumer of energy. The exponential growth in data traffic, as we become ever more dependent on the internet, smartphones and 5G networks, means that the energy demands of service providers are continually increasing.
The challenges in achieving sustainable telecommunications
The path towards a carbon-free telecoms industry is not a simple one. It requires a commitment to transforming established practices and rethinking how networks are built and powered. It is a complex task that touches on economic, social and regulatory issues, and these will require a collective effort to drive change.
Increased energy demand
The adoption of 5G, the Internet of Things (IoT) and cloud services is driving an exponential growth in data traffic. As a result, telecommunications networks are being pushed to their limits.
This has created a need to strike a balance between rapid data transfer and constant connectivity. However, it is a complex undertaking that requires innovative approaches.
Telecoms companies need to invest in energy-efficient technologies. They need to optimise their network architectures and explore renewable energy sources. By adopting such approaches, they will be able to achieve sustainable growth while minimising their environmental impact.
Sourcing renewable energy
Securing reliable, cost-effective renewable energy can be a challenge, particularly in regions with limited access to clean energy sources.
Telecoms facilities, such as base stations and data centres, require a continuous, uninterrupted supply of power. This makes it more complex to incorporate more intermittent renewable sources, like solar or wind.
Similarly, these energy sources require storage solutions, such as batteries, to bridge the gap when renewable energy production is low. However, these technologies can be costly and bring additional technical considerations.
Managing electronic waste
As technology advances, companies need to upgrade their equipment. However, this generates electronic waste, and the disposal of obsolete devices, such as routers, servers and mobile devices, poses environmental risks.
Proper recycling and disposal processes are often costly. They can also be logistically complex, especially with large-scale data centres.
Furthermore, local and regional regulations for e-waste management can vary greatly. This leads to inconsistencies in the way that electronic waste is handled. A lack of standardised practices can mean that waste is not disposed of properly, further contributing to pollution and health risks.
Regulatory and market pressures
Telecoms companies operate in a highly competitive and regulated environment. As a result, there is a need to balance sustainability with profitability. This is an important consideration, especially in a market where consumers demand low-cost services.
Given that carbon emission regulations vary between regions, implementing consistent sustainability strategies can be complicated. Furthermore, non-compliance can result in fines, reputational damage and operational restrictions.
Investors are also starting to prioritise environmental, social, and governance (ESG) factors. Sustainable performance is now closely linked to financial performance, and this is having an impact on investment decisions and access to capital.
Telecoms as an enabler of the energy transition
Despite its energy-intensive nature, the telecommunications sector is uniquely positioned to support the global energy transition. Here are some ways in which telecoms companies can contribute to a more sustainable future:
Facilitating the adoption of renewable energy
Telecommunications networks have an essential role to play in integrating renewables into the energy grid. Advanced communication systems enable the monitoring and control of decentralised energy resources. This makes it easier to manage more intermittent power sources and ensure grid stability.
So-called smart grids allow more efficient and flexible energy management. They use real-time data, automation and advanced analytics to optimise the distribution of electricity, thus ensuring that renewable sources are used effectively.
The Agility Center in Belgium provides a good example of how renewable energy can decarbonise network operations. The data centre is powered by 2,000 solar panels that cover 20% of the site's energy needs. This reduces CO2 emissions by nearly 388 tonnes per year with a guaranteed availability of 99.982%.
Supporting smart cities and the IoT
The development of smart cities is closely linked to telecommunications. At Equans, we are involved in the entire smart city value chain, including studies, financing, implementation, maintenance and operations. Therefore, we are aware of the important role telecoms networks play in supporting the Internet of Things (IoT). These networks enable the collection and analysis of vast amounts of data from various sensors and devices.
In smart cities, IoT-enabled devices can optimise energy usage in buildings. They can manage traffic flow to reduce emissions and improve waste management systems.
By deploying sensors and smart devices, companies can gather real-time data on energy usage, enabling more efficient operations and a reduced environmental impact.
Improving energy efficiency
By investing in energy-efficient technologies, providers can reduce their environmental impact. For example, the deployment of 5G networks (while initially more energy-intensive) can support devices that use less energy per bit of data transmitted.
Similarly, cloud computing can centralise data processing in energy-efficient data centres. By moving operations to the cloud, companies reduce the need for physical servers, which are often energy-intensive.
Artificial intelligence (AI) and machine learning (ML) can also improve network efficiency. By analysing vast amounts of data, these technologies can predict maintenance needs. They can also optimise network operations and support more efficient network management.
Promoting digitalisation and dematerialisation
Digital services like video conferencing and e-commerce reduce the need for physical goods and travel. Consequently, this leads to lower carbon emissions.
Telecoms play a vital role in enabling these digital transformations by contributing to dematerialisation and reduced energy consumption.
For example, in the wake of the COVID-19 pandemic, remote working has become common practice. This has reduced the carbon footprint associated with commuting and also decreased the energy consumption of office buildings.
In summary
The role of telecommunications in the energy transition is not just about meeting regulatory demands and market expectations; it is about welcoming innovation to secure the industry’s future.
As companies embrace this responsibility, they have a unique opportunity to lead by example. By integrating cutting-edge practices, they can reduce their environmental impact while enhancing operational efficiency.
The shift is not merely a response to external pressures. It is also a strategic move, whereby telecoms companies can become pivotal players in a low-carbon economy.
As we move forward, the success of the energy transition will be measured by the sector's ability to turn challenges into opportunities. The industry therefore needs to demonstrate that connectivity and sustainability are not mutually exclusive but mutually beneficial.
