Meeting the Challenge of Our Time: Pathways to a Clean Energy Future for the Northwest aims to represent potential energy futures in enough technical detail to be used as blueprints to develop a future of the Northwest’s choosing.
Stakeholders can use the results of this and other decarbonization studies to formulate policies and make investments and operational decisions to accelerate the clean energy transition and put the Northwest on a deep decarbonization path that is sustainable, affordable, equitable, and meets reliability and security needs.
There are several areas of additional examination that the study suggests pursuing.
Focus on Equity. This study is designed to show the trade-offs between different deep decarbonization pathways, but it does not take into account equity considerations for different communities. The study demonstrates we can decarbonize our economy, but the critical work ahead must focus on how to do so equitably.
Areas for Further Study. Understanding the dynamics of alternative fuel development on refinery activity and relative fuel prices is important for the Northwest. While it might be possible to predict the decline of certain fuels as electrification increases in buildings and transportation, the development of biofuels or electric fuels that also displace fossil fuels may be more challenging to foresee.
This is an unanswered question in almost all deep decarbonization transformations and developing long-term strategies today could mitigate the clean energy transition’s disruptive impacts and avoid unnecessary investments.
This study examined low, normal, and high hydro years; however, it held the likelihood of experiencing these hydro conditions constant through 2050 and did not consider even lower future water years, assumptions that require examination. Follow-on work should involve a scenario in which lower snowpack occurs more frequently, and seasonal dynamics are altered due to climate change.
Sensitivity analyses are needed to understand how a 10% to 20% lower hydro resource would impact other resources, as well as how removing the Lower Snake River dams and retiring the nuclear Columbia Generating Station before 2043 would affect clean power supply. Finally, a combination of all three of these changes in low-carbon resources should be modeled together.
Modeling the retirement of all coal-fired electricity generation by 2030 is an additional area for study, as is modeling natural gas at higher prices than the study assumed and, if possible, modeling natural gas with a higher emissions level to account for upstream emissions and methane leakage.
Focus on Implementation. While this study offers a functional technical representation of low-cost deep decarbonization pathways, successful implementation is more uncertain. Some implementation challenges include:
With several recent international and national reports clearly establishing that there is a small window of time within which to massively reduce fossil fuel dependence, and a U.S. federal government currently focused on increasing, not decreasing, the use of fossil fuels, it is imperative that states and regions in the United States step up to the decarbonization challenge.
Initiatives such as the Green New Deal, the Keep it in the Ground Movement, and 100% Clean Energy campaigns set forth a range of goals and strategies to reduce carbon emissions. Achieving these goals requires technology investment, smart policies, innovation, and regulatory reform to shape the low-carbon energy system of the future.
Solutions need time to be developed and implemented, so policymakers must anticipate them now. Meeting the Challenge of Our Time: Pathways to a Clean Energy Future for the Northwest provides support and direction for policy-makers, advocates, businesses, government leaders, and investors to begin implementing effective solutions for a deeply decarbonized future in the Northwest.
