The internet may seem to exist in the ether, but its plumbing includes a vast network of data centers, also known as server farms, which need power to function. In 2010, data centers represented 2% of all electricity use in the United States. Globally, it equates to 2% of all annual emissions linked to climate change. While that amount may not sound like much, it is almost equivalent to the impact of shipping all goods around the world each year. If the world is to become ever more efficient and reach global climate goals, internet power will need to play its part.
