Science Statistics

From $754 million for global quantum computing markets in 2023 to data centers projected to use 1.5% of global electricity demand by 2030, this page pairs energy and innovation metrics to show where research, infrastructure, and funding collide. You will see why small efficiency gains like PUE improvements can swing power demand, alongside the scale of biomedical publishing and clinical trial registration reaching 450,000+ registered studies worldwide.

Next review Nov 2026
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.
