The energy needed to support data storage is expected to double by 2026. You can do something to stop it. In January, the International Energy Agency (IEA) issued its forecast for global energy use over the next two years. Included for the first time were projections for electricity consumption associated with data centers, cryptocurrency, and artificial intelligence. The IEA estimates that, added together, this usage represented almost 2 percent of global energy demand in 2022 - and that demand for these uses could double by 2026, which would make it roughly equal to the amount of electricity used by the entire country of Japan. We live in the digital age, where many of the processes that guide our lives are hidden from us inside computer code. We are watched by machines behind the scenes that bill us when we cross toll bridges, guide us across the internet, and deliver us music we didn’t even know we wanted. All of this takes material to build and run - plastics, metals, wiring, water - and all of that comes with costs. Those costs require trade-offs. None of these trade-offs is as important as in energy. As the world heats up toward increasingly dangerous temperatures, we need to conserve as much energy as we can get to lower the amount of climate-heating gases we put into the air. That’s why the IEA’s numbers are so important, and why we need to demand more transparency and greener AI going forward. And it’s why right now we need to be conscientious consumers of new technologies, understanding that every bit of data we use, save, or generate has a real-world cost. One of the areas with the fastest-growing demand for energy is the form of machine learning called generative AI, which requires a lot of energy for training and a lot of energy for producing answers to queries. Training a large language model like OpenAI’s GPT-3, for example, uses nearly 1,300 megawatt-hours (MWh) of electricity, the annual consumption of... |
