This study analyzes the potential and consequences of Washington State's use of wind, water, and sunlight (WWS) to produce electricity and electrolytic hydrogen for 100% of its all-purposes energy (electricity, transportation, heating/cooling, industry) by 2050, with 80–85% conversion by 2030. Electrification plus modest efficiency measures can reduce Washington State's 2050 end-use power demand by ∼39.9%, with ∼80% of the reduction due to electrification, and can stabilize energy prices since WWS fuel costs are zero. The remaining demand can be met, in one scenario, with ∼35% onshore wind, ∼13% offshore wind, ∼10.73% utility-scale PV, ∼2.9% residential PV, ∼1.5% commercial/government PV, ∼0.65% geothermal, ∼0.5% wave, ∼0.3% tidal, and ∼35.42% hydropower. Converting will require only 0.08% of the state's land for new footprint and ∼2% for spacing between new wind turbines (spacing that can be used for multiple purposes). It will further result in each person in the state saving ∼$85/yr in direct energy costs and ∼$950/yr in health costs [eliminating ∼830 (190–1950)/yr statewide premature air pollution mortalities] while reducing global climate costs by ∼$4200/person/yr (all in 2013 dollars). Converting will therefore improve health and climate while reducing costs. [ABSTRACT FROM AUTHOR] |
