As expected, car sales have decreased world-wide as a consequence of the Covid-19 pandemic.

Over the last 50 years photons, the particles that make up light, have replaced electrons to transfer data in communication networks.

Today’s computer processors are pretty fast. Under optimal conditions, a desktop can come close to teraflop speeds, which is a million million operations per second .

In 2016, for a few hours, all of Germany ran only on renewable energy , demonstrating that one day, the release of carbon dioxide into the atmosphere could really be avoided.

In 1961, the physicist Rolf Landauer formulated a principle that any transformation of information that takes place in a computer requires energy, thus making zero-power computing a pipe dream.

Over the last few decades the energy landscape has been changing drastically in Europe. An increasing amount of electricity is now generated from renewable sources, such as solar and wind energy.

The energy landscape in Europe is changing rapidly and the percentage of renewables is steadily increasing. For example, in Germany solar and wind power provided an average of 33% of the total electricity production in 2015.

The construction of a building does not only start with its design by architects and engineers.

Ulrich Filippi Oberegger is a senior researcher in the energy management in buildings group of the Institute for Renewable Energy of EURAC Research . He tells youris.

Urban mining is increasingly being taken seriously by industry because it gives access to materials—such as expensive metals used in electronics—that are buried in waste tips and landfills.

Multiple disasters can have a cumulative impact leading to great human and financial loss. The awareness of all possible risks is of fundamental importance.

Twenty five years ago, the German chemist Michael Braungart developed a new approach to recycling, now called "Cradle to Cradle" or "C2C" after the book, Cradle to Cradle: Remaking the Way We Make Things, which he and the American architect William McDonough published in 2002.

Increasingly, many of the plastic products we use every day are no longer based on petroleum raw material . Instead, they are made from biomass such as starch, sugar, corn and other sources that also happen to be food products.

Non-ferrous metals are increasingly in demand because of the electronics industry. "They are used in LED’s, computers, smartphones; this is a much bigger business now," says Kate Hornsby , Waste in Social Environment manager at the Technical University Aachen , Germany.
