The digital revolution has changed the way we live and work with one another. It is represented by IT or information technology, a key component of everyday life in forms such as streaming services, cloud computing, and online services. But with the great growth of IT also came a major problem attached to its coattails: it consumes a lot of energy. The effort for 2024, therefore, should be to not only perfect technology but also make the energy it relies on greener in a race to decrease its footprint on the environment.
This blog examines the numbers and trends in global energy consumption in information technologies. We also examine how using green energy in IT will shape the future and find practical ways to reduce carbon emissions from the tech industry.
The Rising Energy Demands of IT
As the uses of information technologies are increasing, the demands from IT are also rising with its high increases. This is further expressed by a report from the International Energy Agency: Data centers and networks use almost 1-1.5% of global electricity supply; this is expected to surge with the increased demand for digital services.
The energy demand from IT infrastructure is primarily driven by the following:
- Data centers: These centers host the multitudes of servers that run cloud services, websites, and apps—all very hungry consumers of electricity for keeping hardware running and cool.
- Personal Devices: Add up all the smartphones, laptops, and tablets-mostly in energy consumption, especially multiplied by billions of users.
- Telecommunications Networks: Delivering data to these devices requires a lot of energy, particularly now that 5G is arriving.
With the ever-growing move towards adapting to digital changes, IT energy consumption has become an issue not only concerning economic estates but also one in which policymakers need to take great interest.
IT Energy Consumption in Numbers
Following are a few key statistics that have come to the forefront, showing the scale of energy usage within the IT industry:
- In recent years, data centres worldwide consumed approximately 200 TWh of electricity, accounting for roughly 1% of global electricity demand (microsoft).
- This represents approximately 3.7% of global greenhouse gas emissions, on par with the aviation industry's.
- Data transmission networks accounted for 260 to 340 TWh of electricity consumption in recent years. (microsoft).
All these increasing demands have fired up the debate on sustainable energy solutions for technology and its urgent need to go green in IT.
Sustainable Technology Trends to Watch
In 2024, a lot of emphasis is being put on sustainability. Many companies these days use green computing and are trying to balance innovation with being ecologically friendly. Following are some of the sustainable technology trends shaping the future of IT energy consumption:
1. Green Data centres
Data centers are crucial for the internet and quite power-consuming. These days, companies choose green data centres that use renewable energies such as solar, wind, and hydroelectric power. Large technology companies like Google, Microsoft, and Amazon are making big changes to make their data centres carbon-neutral.
2. Edge Computing
It is such a sustainable technology trend that reduces the overall consumption of energy through processing data near its source. Instead of sending data to the cloud servers, which might be far, far away, it allows for data processing on-site or on nearby servers, reducing energy use needed for transmission over long distances.
3. Virtualization and Cloud Optimization
Virtualizing servers, among other optimizations in the cloud, reduces the number of physical hardware needed; this therefore reduces energy costs and, correspondingly, carbon emissions. This becomes even more important as companies increasingly move away from in-house servers to cloud computing services.
4. AI for Energy Efficiency
Artificial Intelligence is being implemented to take this energy efficiency a notch further within IT systems. The AI algorithms can predict energy usage patterns, optimize workload, and eliminate waste. For example, Google's DeepMind AI has been credited with shaving 40% off the energy required to cool data centers.
Green Computing Trends in 2024
Green computing trends are at an edge in 2024. These have developed a compelling need for companies to work in a way that causes minimum or no harm to the environment while continuing to provide high-end computing solutions.
1. Energy-Efficient Hardware
The move to energy-efficient hardware tops the list, with companies developing processors, servers, and storage systems that use minimal power yet do not compromise on performance.
2. Circular Economy in Tech
This is regarding the trend in sustainability wherein IT companies are trying their best to prolong the life of the devices to reduce electronic waste. All this entails old hardware recycling, refurbishing used equipment, and reducing the environmental impact brought about by device manufacturing.
3. Carbon-Neutral Cloud Services
Major cloud service providers are promising to go carbon neutral, and companies in the industry are trying to reduce energy consumption and its reliance on non-renewable energy sources. Companies like Microsoft promise to be carbon-negative starting in 2030.
These trends show that green energy for IT is no longer optional; it is becoming essential to shaping the industry's future.
Importance of Reducing Carbon Footprint from IT
This is attributed to the growing global reliance on digital services, and this growth in carbon footprint is faster in the IT sector than in many other industries. Reducing the IT carbon footprint is the only way to achieve the global climate goals.
Following are some of how the industry can reduce its carbon footprint:
- Transition to Renewable Energy: Transition to renewable energy will, therefore, be key and instrumental in bringing down emissions through wind, solar, and hydro energy. It will also be a good idea for the firms to neutralize their gas emissions by purchasing carbon offsets.
- Practice Energy Efficiency: Efficient software that can ensure lesser energy usage, deploying energy-efficient hardware, and adopting smart cooling technologies in data centres are needed.
- Extend product lifecycles: Encouraging longer device usage and electronic waste recycling is essential to a manufacturing and waste management policy sensitive to the ecology.
With a greater focus on sustainable technology trends, many organizations are taking positive steps toward reducing their carbon footprint. However, there is still much work to be done.
Sustainable Energy Solutions for Tech
However, sustainable energy solutions for technology have stopped being an option; they've now become necessary. As long as the demand for digital services keeps increasing, so does the need for energy feeding them from cleaner sources. Following are some of the most sought-after sustainable energy solutions in which the tech industry is heavily investing:
1. Solar and Wind Power
The IT industry is increasingly adopting renewable energy sources such as solar and wind. Giants in this sector, Apple and Google, are leading the way in this regard. Google, for example, vowed to operate all of its global operations with renewable energy.
2. Hydroelectric Power
Hydroelectric power is an emerging and trustworthy source of energy that data centres are considering. Hydropower has provided a continuous flow of energy, as with fossil fuels, without carbon emission.
3. Energy Storage Solutions
Battery storage systems are critical in balancing energy supply and demand because they balance and regulate their roles in demand and supply. Storage of excess energy produced from renewable sources means the data centres will have a steady power supply, even without relying on fossil fuels during increased demand periods. 4. Waste Heat Recovery
Some data centres are already experimenting with waste heat recovery systems that capture the generated heat from the servers and reuse it for heating other nearby buildings or again convert it back to electricity, adding to the overall energy efficiency.
Future of Green Energy in IT
It's not all about faster processors and huge data centres; the future of IT is about sustainability. Adopting green energy in IT means that, over time, the tech industry's environmental impact will lessen.
