On Thursday, Washington state's House of Representatives passed a bill that will require 100 percent of the state's electricity generation to be carbon emissions-free by 2045.

A previous bill was passed in the state's Senate in early March, though the House amended its version, so the Senate will have to vote again on the bill's updated language, according to the Associated Press. However, the bill previously passed the Senate on a 28-19 vote, and it is expected to pass again. The legislation was part of a key campaign promise made by Governor Jay Inslee, who is expected to sign the resulting bill.

Washington has massive hydroelectric resources as well as a 1.1 gigawatt (GW) nuclear power facility in Richland, Washington. Seventy-five percent of the electricity it produces is already free of carbon emissions.
