Can renewable energies such as solar, wind and batteries save Earth from the ravages of global warming? Climatologists aren’t sure whether those technologies can overcome humanity’s addiction to cheap fossil fuels, which cause the lion’s share of carbon emissions. Superpowers like the United States and China are taking advantage of the falling prices of renewables and cutting back on coal use, but developing countries directly offset those efforts. Nature contributor Jeff Tollefson will help you better understand this delicate dance, but don’t assume you will come away optimistic.
