Porterville, California, is about to make transportation history. The little Californian city only receives an average of 13 inches of rain a year, which makes it particularly vulnerable to atmospheric inversion, which holds in the exhausts from vehicles, agriculture, and other sources. Thanks to a determined city hall, the number of Stage 1 smog alerts declined from 100% per year, in the 1970s, to almost zero. On December 7, the California Air Resources Board awarded $9.5-million to replace its’ entire bus fleet. By January, 2018, Porterville should have North America’s first 100% electric municipal bus system.
