New research reveals AI's rapidly increasing energy demands, with estimates suggesting it could account for nearly half of data center power usage by the end of 2025. This surge in consumption raises significant environmental concerns and calls for greater transparency from AI companies.

AI's Escalating Energy Appetite

Artificial Intelligence (AI) is rapidly becoming one of the most significant consumers of energy in the tech sector. Recent research indicates that AI's power demand could account for up to 20% of global data center electricity consumption, with projections suggesting this figure may double by the end of 2025

Researchers have attempted to quantify the energy consumption of various AI tasks:

  • A single query to the open-source Llama 3.1 8B engine uses approximately 114 joules of energy, equivalent to running a microwave for about a tenth of a second

    2

    .
  • Larger models like Llama 3.1 405B require around 6,706 joules per response

    2

    .
  • AI video generation is particularly energy-intensive, with the CogVideoX model consuming 3.4 million joules to generate a five-second video

    2

    .

A typical AI user session, including 15 text queries, 10 image generations, and 3 video creations, could consume about 2.9 kWh of electricity – equivalent to running a microwave for three and a half hours

Global Impact and Future Projections

The International Energy Agency (IEA) reports that data centers accounted for 1.5% of global energy use in 2024, consuming around 415 terawatt-hours

. This figure is expected to more than double by 2030, potentially surpassing 900 TWh

. AI is a primary driver of this increase, with estimates suggesting it could require almost as much energy as Japan uses today by the end of the decade

The rapid growth in AI energy consumption poses significant environmental challenges:

  1. Carbon emissions: Data centers are predicted to emit 2.5 billion tons of greenhouse gases by the end of the decade, three times more than without generative AI

    2

    .
  2. Water usage: AI infrastructure requires vast amounts of water for cooling, straining already limited resources in some regions

    .
  3. Impact on corporate sustainability goals: Tech giants like Google and Microsoft have acknowledged that AI is complicating their ability to meet internal environmental targets

Lack of Transparency and Regulation

A major issue in addressing AI's environmental impact is the lack of transparency from AI companies regarding their energy usage

. There are several reasons for this opacity:

  • Competitive concerns in the AI industry
  • Technical difficulties in isolating AI-specific energy consumption
  • Absence of standardized reporting frameworks or regulations

This lack of transparency makes it challenging for researchers and policymakers to accurately assess and address the environmental impact of AI systems

Despite these challenges, there are growing efforts to make AI more environmentally accountable:

  • The Green Software Foundation is developing sustainability standards specifically for AI

    .
  • The EU AI Act encourages sustainability through risk assessments

    5

    .
  • Some AI companies are investing in renewable energy and researching more efficient training methods

    .

However, these initiatives are not yet standard across the industry, and there remains a pressing need for greater transparency and regulation to ensure the sustainable development of AI technology.
