Search engines that do not automatically display an interactive map or widget are also less energy intensive (Ecosia, StartPage, Lilo). The more additional functionality there is, the more power hungry the system is. In general, a shorter search process has less energy and battery impact and can help reduce the overall carbon impact of the whole chain. A search consumes more energy via a mobile browser than with an application (64% carbon savings on average). The energy consumption of internet searches is based on both network and user energy consumption. Some browsers are also more energy efficient than others. While traditional web browsers and search engines dominate the global market ( 5), they do not all have the same ecological footprint and more ethical and/or ecological search engines like Ecosia or Lilo are starting to stand out, especially in Europe. ( 4) It is estimated that Google receives 99 000 requests per second. ( 3)Īlmost 93% of Internet traffic comes from search engines. ( 2) By way of comparison, the energy consumption of a data centre is equivalent to that of 30 000 people in Europe. Data centres and data transmission networks are responsible for nearly 1% of energy-related greenhouse gas emissions. The electricity used comes mainly from non-renewable energies that pollute. As for a computer, these installations are very energy consuming. This data is stored in infrastructures: computer centres – or data centres. ( 1) Browsing or searching on the Internet consists in transmitting information materialised by data.
