"In some instances, AI data centres are powered completely by renewable energy. Unfortunately, unless the data centre builds new renewable energy sources to supply 100% of its power, this still results in an increase in fossil fuel usage. Why? Because if the data centre is using pre-existing sources for renewable energy, it is taking that energy away from other consumers that need it. To pick up the slack, we must generate more energy, and most of that generation is done using coal or natural gas."
