The internet or the so-called “World Wide Web” is accessible all over our earth and on the internet we have over 1 billion websites available to you at any time of the day. For every of these websites we need to run a server that will look for requests and access points in between to route the data back and forward between you and the data centre hosting the website. All of these requires electricity to run and sadly many of these data centres make use of old school coal energy. To put the polluting caused by the internet into perspective, then if the internet was a country it would be the 6th biggest polluter in the world.

Internet speeds become faster and faster and the same with our devices. Because of this we tend to build even more demanding websites instead of doing the opposite.
