In recent decades, the use of air conditioning has expanded enormously, which has led to a significant increase in energy consumption.

According to an article published in the journal Nature, a team of researchers from the University of Stanford (USA) has created a new material that can alleviate the problem. It is thinner than an aluminum foil and performs two functions: on the one hand it sends the heat in a room into space as infrared radiation and on the other it reflects the rays that come from the sun. In this way, in the room below the roof where the plate is located, a temperature drop of five degrees can be obtained.
