===Models and training===
Many recent projects in deep learning have used increasingly large computational resources to create models
The compute resources used for the largest model training runs was shown to have doubled in size every 3.4 months from 2012-2018<ref>{{Cite web|url=https://openai.com/blog/ai-and-compute/|title=AI and Compute|date=2018-05-16|website=OpenAI|language=en|access-date=2021-03-27}}</ref>.

== Data Centres ==
Data centres accounted for almost 1% of global energy demand in 2019<ref>{{Cite web|url=https://www.iea.org/reports/data-centres-and-data-transmission-networks|title=Data Centres and Data Transmission Networks – Analysis|website=IEA|language=en-GB|access-date=2021-03-27}}</ref>, at around 200TWh, and while demand increases, efficiency gains mean this may stay flat for now<ref>{{Cite journal|last=Masanet|first=Eric|last2=Shehabi|first2=Arman|last3=Lei|first3=Nuoa|last4=Smith|first4=Sarah|last5=Koomey|first5=Jonathan|date=2020-02-28|title=Recalibrating global data center energy-use estimates|url=https://science.sciencemag.org/content/367/6481/984|journal=Science|language=en|volume=367|issue=6481|pages=984–986|doi=10.1126/science.aba3758|issn=0036-8075|pmid=32108103}}</ref>. AI's total impact then can be estimated as a fraction of this. AI may itself offer efficiency gains for data centres by optimising control systems<ref>{{Cite web|url=https://blog.google/outreach-initiatives/environment/deepmind-ai-reduces-energy-used-for/|title=DeepMind AI reduces energy used for cooling Google data centers by 40%|date=2016-07-20|website=Google|language=en|access-date=2021-03-27}}</ref>.
Estimates of electricity use of AI
=== Cloud comparison ===
The major cloud computing providers, Amazon, Google and Microsoft, have varying targets and carbon intensities for their services.
Google now publishes hourly estimates of the proportion of carbon-free energy (CFE) and the carbon intensity for all its cloud regions<ref>{{Cite web|url=https://cloud.google.com/sustainability/region-carbon|title=Carbon free energy for Google Cloud regions|website=Google Cloud|language=en|access-date=2021-03-27}}</ref>.
