Manufacturers and marketing agencies exploit the fact that every power source carries its own unique portfolio of side effects to create the terms of discussion that best suit their needs. Electric-car makers like to point out, for instance, that their vehicles can be charged from renewable sources, such as solar energy. Even if that were possible to do on a large scale, manufacturing the vast number of photovoltaic cells required would have venomous side effects. Solar cells contain heavy metals, and their manufacturing releases greenhouse gases such as sulfur hexafluoride, which has 23 000 times as much global warming potential as CO2 , according to the Intergovernmental Panel on Climate Change . What’s more, fossil fuels are burned in the extraction of the raw materials needed to make solar cells and wind turbines—and for their fabrication, assembly, and maintenance. Th...
