Today it is estimated that the Internet and its infrastructure and networks consume 868 billion kWh of power annually and that number is only going to grow in the coming years with increased numbers of websites and other factors.

That is 868,000,000,000,000 Watt hours of electricity!

However the amount of electricity just for the Internet data and storage servers, it consumes 112.5 Billion kWh. Taking into account that around 41% of the world’s energy comes from coal, 6% from oil, and 20% from natural gas, and the fact that coal produces 2.095 pounds of CO2 per kWh, oil produces 1.969 pounds per kWh, and natural gas produces 1.321 pounds per kWh then the total CO2 produced by the servers annually is about 139.6 billion pounds of CO2. Now considering that there are 1,463,632,361 Internet users in the world that means the CO2 per person is around 95.3099 pounds person.
