The resulting sharp drop in sulphate particles in the atmosphere, however, caused a surge in solar radiation absorbed by the oceans along the world's busiest shipping routes, according to a study by climate researcher Leon Simons.According to Simons, a board member of the Club of Rome - a nonprofit group of intellectuals and business leaders that discusses major global issues - the previously higher levels of sulfur particles had helped reflect some solar radiation.
An obvious example is wind turbine blades, which have a design life of roughly 20 years before they need to be replaced due to worn parts or because they are far less efficient than newer blades. , but tend to steer clear of the earliest generation of wind blades, which were made from hard-to-process composite materials.
In contrast, old electric vehicle batteries are in high demand by firms that produce new batteries, as many of the key ingredients contained in them can be processed and used again.
