July 17: Altinay Karasapan from the Washington non-profit Climate Solutions guides us through Washington's Climate Commitment Act and the benefits there for us.

July 4: Deepa Sivarajan of the Climate Solutions on Energy Codes

  • study by the Northwest Energy Efficiency Alliance showing that because the 2018 energy code itself required such high levels of efficiency, and because electric heat pumps are so much more efficient than even the newest gas appliances, 88% of new homes in Washington are being built with electric space and water heating anyway, regardless of the most recent code update  

  • Two cost-benefit analyses showing that new all-electric homes are cheaper to build than mixed fuel buildings 

    • report prepared for the Washington State Department of Commerce in May 2022 found all-electric residential new construction cost-effective across the state. Compared to a mixed-fuel new home that needs air conditioning, an all-electric new home saves about $2,000 in upfront costs.

    • cost-benefit analysis conducted by RMI for Washington’s 2021 residential energy code process found that new mixed-fuel homes in both Seattle and Spokane cost more than $7,200 more to build than all-electric homes. 

  • Information on the Seattle Building Emissions Performance Standard (BEPS) which, if passed, will tackle emissions from existing buildings over 20,000 square feet, and will cut building emissions in Seattle by 27% by 2050

  • An Op-ed on Seattle Building Emissions Performance Standard for the Seattle Times that was published today

May 15: Don Marsh of the Washington Clean Energy Coalition outlines how Puget Sound Energy is proposing to the Utilities Commission that PSE continue present levels of methane pollution for 26 more years and via the link below provides a simple way for citizens and ratepayers to comment on PSE’s proposal.
