Cal­i­for­nia law­mak­ers passed a bill that would require 100 per­cent of the state’s ener­gy to come from car­bon-free sources. The pro­pos­al would set a goal of phas­ing out all fos­sil fuels by 2045 but does not include a man­date or penal­ty. Sup­port­ers say the mea­sure would help address cli­mate change and boost Cal­i­for­ni­a’s clean ener­gy econ­o­my. Crit­ics say the bill is unre­al­is­tic and would sad­dle fam­i­lies and busi­ness­es with high­er ener­gy bills. The mea­sure now heads to the gov­er­nor’s desk.
