  6. 6 Why a Northwest Deep Decarbonization Study? Common set of assumptions to inform decisions about how the clean energy transition could unfold over the coming decades Unbiased, analytical baseline for the region Variety of pathways to lower carbon emissions​ Surface trade-offs, challenges, and practical implications of achieving mid-century targets​ Broaden conversations about actions needed cleanenergytransition.org @CETransition

  7. 7 Study Questions How does the energy sector need to transform in the most technologically and economically efficient way?​ How does electricity generation need to be decarbonized to achieve economy-wide carbon reduction goals?​ What if we can’t achieve high electrification rates?​ What is the most cost-effective use for biomass? What if biomass estimates are wrong?​ What would increased electricity grid transmission between the NW and CA yield? cleanenergytransition.org @CETransition
