On May 31, the day before President Trump announced that the U.S. will withdraw from the Paris Agreement on climate change, the California Senate passed a bill mandating 100% of all electrical generation be from so-called “renewable” sources that emit no carbon dioxide by 2045.  As the vote was strictly along party lines, this means that the General Assembly will also likely pass it and send it to Governor Brown for signature.
 
California isn’t alone. The “100% renewables” movement has been sweeping across American colleges, and similarly “progressive” towns and some states, such as Hawaii and Vermont. This movement has resulted in state laws, local ordinances and policies at both levels that require 100% of a city or state’s electricity to come from renewable power sources such as wind and solar.
