Data centers already account for 1.5% of global electricity demand projected by 2030, even as their operating choices can still swing energy use by about 90% through PUE improvements. At the same time, the research pipeline behind that compute keeps expanding, from PubMed’s roughly 33,000 biomedical and life science journals to 450,000 plus clinical trials registered worldwide. This post connects those signals across computing, energy, and biotech to show how fast the science system is scaling and what it costs.
Key Takeaways
- 1.3% of global greenhouse-gas emissions came from direct CO2 emissions of the global computing sector in 2019
- 201.2 GW of U.S. data center capacity was in operation as of 2023 (including colocation, corporate, and wholesale facilities)
- 17% of global electricity consumption was attributed to data centers and other IT workloads in 2022
- 2.1°C is the temperature increase associated with current national pledges and targets by 2100 (IPCC AR6), implying continued high energy demand for mitigation and adaptation research
- China’s GERD reached ¥3,077.1 billion CNY in 2021 (OECD GERD dataset for China)
- The European Union’s Horizon Europe programme has an €95.5 billion budget for 2021–2027
- 2.3 million articles were published in 2023 in the Web of Science Core Collection (Clarivate Science Citation Index Expanded coverage reported in annual trends)
- The global number of biomedical and life science journals indexed in PubMed was about 33,000 in 2024 (NLM PubMed journal count metric)
- The mean global field-weighted citation impact (FWCI) for the European Union in 2021 was 1.0 (world average baseline) per SCImago/Eurostat-style bibliometric reporting
- 73% of respondents reported using electronic lab notebooks (ELNs) as of 2022 in a global survey (research informatics adoption survey)
- 91% of enterprises report using some form of data management platform or data lake strategy for analytics in 2024 (Gartner survey findings reported by vendor-ecosystem press)
- In 2024, NVIDIA’s H100 GPU was the basis for many leading AI supercomputers ranked in the Top500 list (Top500 list entries document system GPU composition)
- In 2023, the global quantum computing market reached $754 million (Fortune Business Insights estimate)
- The global market for lab equipment was $80.6 billion in 2023 (IMARC Group market size report)
- CRISPR-related therapeutics had 10 approved products as of 2024 (FDA/CDER or peer-reviewed review count based on approvals list)
Data centers and AI are surging while driving energy and emissions, yet PUE gains and R&D funding are key.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
