Washington Voters Adopt Renewable Portfolio Standard for Major Utilities
On November 7, 2006, Washington state voters approved ballot initiative 937, setting renewable energy standards for utility companies in the state. The measure requires all utilities serving 25,000 people or more to produce 15% of their energy using renewable sources by 2020. Such sources include wind, solar, and tidal power as well as landfill-methane capture. With the initiative’s approval, Washington becomes the 23rd state to implement a renewable portfolio standard. Washington is the second state to adopt an RPS by ballot initiative, following Colorado's passage of an RPS in 2004.
