Websites play a significant role in the internet’s overall carbon footprint.

The internet consumes roughly 1,021 TWh of electricity each year—more than the entire United Kingdom. This massive energy demand comes from data centers, networks, and the devices we use to access online content. Every time a website loads, data is transferred across global infrastructure, and that process requires energy — much of which is still generated from fossil fuels.

The internet’s carbon footprint now exceeds the airline industry, with data centers consuming enough energy to power 50,000 homes. Web hosting alone contributes 2% to global carbon emissions.
