A groundbreaking study led by Alex de Vries-Gao, a PhD candidate at Vrije Universiteit Amsterdam's Environmental Research Institute, reveals that artificial intelligence (AI) systems could consume more electricity than Bitcoin mining operations by late 2025. This surge would account for nearly half of global data center power consumption.
The Rising Energy Appetite of AI Hardware
The research, published in Joule journal, employed supply chain analysis to track AI-specific chips:
- NVIDIA and AMD's 2023-2024 AI accelerator modules collectively reach 3.8 gigawatts in thermal design power (TDP) - equivalent to Ireland's annual electricity consumption
- Projected 2025 demand for NVIDIA/AMD systems alone: 5.3 gigawatts
- Including other manufacturers using TSMC's CoWoS packaging: Potential 9.4 gigawatts total demand (46-82 terawatt-hours annually)

Key Findings: Technology vs Efficiency Paradox
- "Bigger is Better" Mentality: Similar to cryptocurrency mining, AI development prioritizes scale over efficiency
- TSMC's CoWoS Packaging: Critical for modern AI accelerators, with production capacity doubling from 126,500 wafers (2023) to 327,400 wafers (2024)
- Potential Efficiency Breakthroughs: DeepSeek's R1 model demonstrates competitive performance with lower-tier hardware
Transparency Challenges and Regulatory Needs
The study highlights concerning trends in corporate transparency:
- Google discontinued its AI energy consumption reporting
- Lack of standardized metrics makes environmental impact assessment difficult
- Researchers call for mandatory disclosure policies to inform sustainable development
FAQ: Understanding AI's Energy Impact
Q: How does AI's energy use compare to traditional computing?
A: AI workloads require 5-10x more power due to complex parallel processing and memory bandwidth demands.
Q: What solutions could reduce AI's carbon footprint?
A: Three approaches show promise: specialized low-power chips (like DeepSeek's), algorithmic efficiency improvements, and renewable-powered data centers.
Q: Why is TSMC's CoWoS technology significant?
A: It overcomes the "memory wall" bottleneck by integrating processors and high-bandwidth memory in single packages, enabling faster processing with reduced energy waste.
👉 Explore sustainable tech investment opportunities
Q: What percentage of global electricity might AI consume by 2030?
A: Current projections suggest 1-3% of global supply if growth continues unchecked, rivaling small nations' total consumption.
The Path Forward: Balancing Innovation and Sustainability
While AI's capabilities continue expanding, the study emphasizes the urgent need for:
- Standardized energy reporting frameworks
- Efficiency-focused hardware development
- Policy incentives for green computing initiatives
The coming years will test whether technological advancement can coexist with environmental responsibility as AI reshapes our digital infrastructure.
