Researchers at the University of Southampton have mapped the global locations of major renewable energy sites, which they say will provide a valuable resource to help assess their potential environmental impact. Their study, published in the Nature journal Scientific Data, shows where solar and wind farms are based around the world – and reveals both their infrastructure density in different regions and approximate power output. It is the first-ever global, open-access dataset of wind and solar power generating sites. The estimated share of renewable energy in global electricity generation was more than 26% by the end of 2018 and solar panels and wind turbines are by far the biggest drivers of a rapid increase in renewables. Despite this, until now, little has been known about the geographic spread of wind and solar farms and very little accessible data exists.
