Democratic presidential candidate Jay Inslee released a plan Friday to impose a 100% clean energy mandate, requiring all U.S. electricity to be carbon-neutral by 2030.

His proposal for a national clean energy standard would put “America on a path to having all clean, renewable and zero-emission” electricity by 2035, his campaign said in the plan roll-out, eliminating the use of fossil fuels. Such broad language allows for the inclusion of nuclear power, and carbon capture technology, along with wind and solar.
