What would it take for the world to convert to 100% renewable energy?According to two researchers, a massive build-out of solar and windpower could accomplish the task by 2030.
While the task may be politically insurmountable, the major resources of steel, concrete and minerals are available. The researchers say. Rareearth supply–which has been a hot topic of late–would be the onlybottleneck. However, this could be overcome with increased mining,recycling and work-around technologies.
"We wanted to show that wind, water, and solar power are available tomeet demand, indefinitely," study co-author Mark Delucchi told NationalGeographic.
The detailed study was published last month in the journal Energy Policy. Nat Geo’s Mason Inman explores the idea at the link below.
