In 2023, tech giants Google and Microsoft each consumed 24 terawatt-hours (TWh) of electricity, surpassing the energy usage of over 100 countries. This striking revelation, detailed in an analysis by Michael Thomas, highlights the immense energy demands of these companies, reflecting both their substantial environmental footprint and their economic might.
Energy Consumption Compared to Countries
The 24 TWh consumed by each company is equivalent to the entire annual energy consumption of Azerbaijan, a country with a GDP of $78.7 billion. This consumption also exceeds that of several nations including Iceland, Ghana, the Dominican Republic, and Tunisia, each of which consumed 19 TWh in 2023. It even outpaces Jordan, which used 20 TWh, and nearly matches Libya’s 25 TWh and Slovakia’s 26 TWh.

Environmental Impact and Data Centers
The staggering electricity usage of Google and Microsoft highlights the significant environmental impact of data centers, which power a vast array of services from cloud storage to artificial intelligence. These facilities are essential for modern computing but come at a high energy cost. The comparison between the energy consumption of entire countries and these two companies illuminates the colossal scale of Big Tech’s operations and its substantial carbon footprint.
Economic Might Versus Energy Use
While their energy consumption is immense, the economic output of Google and Microsoft dwarfs that of many countries with similar energy usage. In 2023, Google generated $305.6 billion in revenue and contributed approximately $739 billion to the global economy through its services like Google Search, Google Cloud, and YouTube. Microsoft, on the other hand, posted a revenue of $211.9 billion, with a significant economic impact from its widespread use of products such as Microsoft Windows, Office, and Azure.
In comparison, Azerbaijan’s GDP was about $78 billion, Slovakia’s around $127 billion, and Iceland’s approximately $30 billion in 2023. The financial power of Google and Microsoft far exceeds the GDPs of these nations, illustrating the vast economic scale of these tech giants relative to their energy consumption.
Renewable Energy and Sustainability Efforts
The high electricity consumption of Google and Microsoft prompts ongoing discussions about sustainability and the adoption of renewable energy sources within the tech industry. Both companies have made significant strides in this area, with ambitious goals for the coming years.
Google has been a pioneer in using renewable energy and has been carbon neutral since 2007. The company aims to operate on 24/7 carbon-free energy across all its data centers by 2030. In 2023, Google continued to expand its investments in renewable energy projects, including wind and solar, to meet its sustainability targets.

Microsoft has also committed to becoming carbon-negative by 2030, meaning it aims to remove more carbon from the atmosphere than it emits. The company targets zero waste production and positive water usage by the same year. In 2023, Microsoft increased its contracted portfolio of renewable energy assets to over 19.8 gigawatts, covering projects in 21 countries. These efforts are part of a broader strategy to reduce both direct and indirect emissions, particularly those associated with the construction of new data centers and hardware components.
