Electricity: The Energy Appetite of AI
The immense computational power required to train and run AI models comes with a massive energy bill. Training OpenAI’s GPT-4 model alone consumed an estimated 51,773 MWh of electricity (EIA, 2024; The Economist, 2024). This is enough energy to power 50 American homes for 100 years. The energy demands are not just for training; a ChatGPT search takes up 10 times as much data as a Google search (Goldman Sachs, 2024).
The global electricity consumption of data centers is on a steep upward trajectory. The current power demand of ~130TWh will increase to 400TWh for the mid-case and goes up to ~560TWh by 2030 (Enerdata, 2024). To illustrate the scale, 560 TWh is equivalent to the annual power demand of a country like Canada (Enerdata, 2024). Much of this energy is not even for computation but is instead consumed by cooling systems and backup systems. With the US having around 50% of the world’s data centers, the absence of proportional growth of renewable sources can lead to a lot of fossil fuels being burned, worsening carbon emissions.
⚡️ GPT-4 used 51,773 MWh to train — enough to power 50 homes for 100 years.
⚡️ Global data center electricity usage is projected to reach 560 TWh by 2030 — equal to Canada’s total energy demand.
⚡️ Just one data center can consume as much electricity as 50,000 homes.
⚡️ Much of the energy is not even used for computation but for cooling and backup.
⚡️ Sam Altman from OpenAI is targeting solar energy as a solution for this problem (WSJ, 2024).
The voracious energy appetite of AI is a significant concern for the global energy grid. As the number of data centers grows, the demand for power will continue to increase. With much of this power coming from fossil fuels, the resulting carbon emissions trap heat and contribute to global warming. Some thought leaders are already exploring solutions, such as using solar energy to power these facilities. Building a sustainable future for AI requires a conscious effort to power our digital world with clean and renewable sources.
