How can the environmental impact of websites be assessed and reduced?

Every website has an impact on the environment. In order to access a web page and display it in a browser, data must be carried and processed, therefore energy and CPU (Central Processing Unit) power are consumed; it is necessary to use a computer, servers and a network, whose production and use contribute to resource […]

Selective data sorting against dark data

According to a study by Veritas, 52 % of company data stored on servers is never used. This inert data is what is known as dark data. This can be data collected within the frame of an abandoned project or data that complies with regulatory compliance requirements and that has not been deleted within the legal […]

5G : energy efficiency “by design”

The progress made by mobile networks over the years is not measured only by their operational performance and the service delivered to the end customer. They are also judged on their ability to take into account societal and environmental issues, particularly those related to energy consumption. On this subject, the progress made is substantial and […]

The Internet of Energy has introduced a new breakthrough in the energy sector

While the Energy Information Administration, the US Agency for Energy Information, predicts an increase in global energy consumption by 48% in less than thirty years, imagine what solutions could be used for successful energy transition, limiting the environmental impact of the energy system and thus contributing to a sustainable planet? Bob Metcalfe, the inventor of […]
