Dan Aas focuses on climate and clean energy policies, using E3’s PATHWAYS model to chart the course to a low carbon future. Currently, he is examining the implications of deep decarbonization in California for natural gas utilities’ business models and local governments’ planning and policy development. Dan also supports E3’s strategy practice, such as identifying opportunities for utilities to benefit from DER deployment.

Dan’s interest in energy and environmental policy stems from his concern about climate change, particularly its impacts on the least well off. He is fascinated by the technical and social complexity of the problem and is especially interested in understanding how policies work best within and between different types of jurisdictions. Previously Dan pursued these interests at the Energy Foundation, the Natural Resources Defense Council, Tetra Tech, and as an intern in the office of CPUC President Michael Picker.

Dan was drawn to E3 by its reputation for independent analysis and the opportunity to tackle thorny policy issues for a diverse client base. An avid reader of contemporary and science fiction, Dan also likes to fish, bike, hike, and see live music.

Pacific Northwest Pathways to 2050 | NW Natural, 2018

E3 analyzed regional 2050 decarbonization scenarios for the Pacific Northwest on behalf of NW Natural, a gas distribution business in Oregon and Southwest Washington. Unlike prior studies, E3’s focused on space heating technologies: both how they perform in cold temperatures and affect the costs of serving heating loads. E3 analyzed four scenarios — two maintaining direct use of gas in buildings, and two assuming large-scale building electrification — and found similar 2050 costs among the gas and cold-climate electric heat pump scenarios, and higher costs in the standard electric heat pump scenario. Gas scenarios require three things beyond the decarbonization strategies common to all scenarios: reducing the carbon intensity of natural gas by blending up to 30 percent carbon-neutral renewable natural gas (RNG) and hydrogen; high building energy efficiency; and deeper GHG reductions in non-building sector emissions. Electrification scenarios require rapid consumer adoption of electric heating technologies, especially cold-climate heat pumps, and significant electricity sector investments to address winter peak demand from electric space heating.
