The Washington Senate today approved a sweeping, historic bill to commit the state to 100 percent clean energy from renewable and zero-emission sources.

Senators voted 28-19 in favor of Senate Bill 5166, sponsored by Sen. Reuven Carlyle (D-Seattle). The bill would require all electric utilities in Washington to transition to a 100-percent, carbon-neutral electricity supply by 2030 and to 100-percent carbon-free electricity by 2045.

“It’s simply time to move past the era of carbon into the next generation with modern, 21st-century energy systems using integrated wind, hydro and solar power,” Carlyle said. “I’m proud that this is the strongest, 100-percent clean energy bill adopted in the nation, and we thank Hawaii and California for paving the way. Now, it’s up to the other states to follow our lead.”

Electricity remains the largest source of carbon emissions worldwide and is the third-highest emitting sector in Washington, after transportation and buildings.

Senate Bill 5166 would make Washington one of the first states in the nation to commit broadly to reducing greenhouse gas emissions from electricity while adopting a precise action plan to do so. It is also the most extensive measure on climate action that Washington’s Legislature has adopted since 2008, when it committed the state to reducing overall greenhouse gas emissions to 1990 levels.

The bill is part of a wider package of Senate legislation to make a meaningful reduction in Washington’s carbon footprint.

It now goes to the House of Representatives for consideration.
