AI systems could account for 20% of global electricity consumption by 2025

AI systems have evolved rapidly in recent years and have become an essential component of many technologies that impact our everyday lives. Although AI offers many benefits, there are also concerns about its energy consumption. This article highlights the energy consumption of AI systems worldwide and presents solutions to reduce this consumption.

The current energy consumption of AI systems

The exact energy consumption of all AI systems worldwide is difficult to quantify, as it depends on a variety of factors: Type of AI task, specific model, hardware architecture, efficiency of the training process, and many others. Some AI models, especially Deep Learning models, require huge amounts of computing power, which directly impacts energy consumption. A well-known example is the training of AI models such as OpenAI’s GPT-3, which takes thousands of GPUs over weeks.

Some estimates suggest that training a single large AI model can release as much carbon dioxide into the atmosphere as five cars do in their entire life cycle. It is estimated that the AI and IT industries together could account for up to 20% of global electricity consumption by 2025.


  • Scalability: As AI models become more complex, their power requirements also increase.
  • Accessibility: high energy costs could mean that only large companies have the resources for advanced AI research.
  • Environmental impact: Increased energy consumption has a direct environmental impact, especially if the energy comes from non-renewable sources.

Solutions for energy saving

  1. More efficient models: Researchers are working to develop models that require less data and computing power. One approach is to use “TinyML”, which aims to run AI models on microcontrollers.
  2. Pruning: This involves removing unnecessary parts of a neural network, making it leaner and more efficient.
  3. Quantum computing: although still at an early stage, quantum computing may be able to perform complex AI tasks with a fraction of the energy consumption of conventional systems.
  4. Use of renewable energy: Companies can reduce the carbon footprint of their AI training by using renewable energy sources.
  5. Hardware optimization: New chips and hardware architectures designed specifically for AI tasks can significantly reduce energy consumption.
  6. Transfer Learning: Instead of training models from scratch, already trained models can be adapted to learn new tasks with less data and in less time.
  7. Federated Learning: where training is distributed across many devices, reducing energy consumption and the need for centralized, energy-intensive data centers.
  8. AI-driven energy management systems: Using AI to monitor and optimize energy consumption in data centers, factories, and other facilities.


While the energy consumption of AI systems is a concern, there are promising solutions to reduce that consumption and make the technology more sustainable. The combination of technological advances, best practices, and industry engagement will be critical to managing AI’s energy needs and maximizing its positive impact on the world. It is not only a technical challenge, but also an ethical responsibility to ensure that the benefits of AI can be realized without endangering our environment.
