John de Villier

John de Villier joined E3 in 2021 as a member of the Climate Pathways and Distributed Energy Resources groups in San Francisco. His most recent work investigates questions surrounding large-scaled building electrification and fuel switching, from its role in achieving emissions reduction and clean energy policy goals to its subsequent impacts on resource needs in the gas and electric systems.

John’s interest in the impacts of climate change and its potential solutions motivated his previous roles as a consultant and subject matter expert covering emerging technologies in the energy industry, and, earlier still, as a biological field researcher; he brings his experience and expertise from each of these areas to his work at E3.

John spends free time reading whatever he can get his hands on, tinkering with photography, and using home-cooked meals with friends as an excuse to talk about plants.

New York Distributed Solar Roadmap | NYSERDA, 2021

Working with the New York Department of Public Service (DPS) and the New York State Energy Research and Development Authority (NYSERDA), E3 supported the development of a new roadmap for New York to achieve the installation of at least 10 Gigawatts of distributed solar by 2030. The roadmap lays out a path that will expand renewable energy in New York, generating enough clean energy to power 700,000 additional homes, while also prioritizing an equitable expansion of New York’s distributed solar infrastructure. E3 contributed to the distributed solar framework by providing analysis that informed the plan’s policy recommendations. E3 developed a supply curve model for distributed solar projects in New York and used this model to evaluate program costs for different incentive program options. The analysis was used to inform the roadmap’s ultimate recommendation to extend the current NY-Sun Megawatt Block incentive program to help achieve the 10 GW target.

US Climate Alliance Greenhouse Gas Emissions Scenarios to Net Zero | US Climate Alliance, 2021

E3 provided modeling and scenario analysis to support the US Climate Alliance’s 2021 Annual Report. The report highlights the progress Alliance members have already made toward reducing greenhouse gas (GHG) emissions, and using E3’s modeling, details multiple scenarios of Alliance-wide GHG emissions through 2050. E3 evaluated Alliance-wide GHG emissions through 2050 using E3’s PATHWAYS and RESOLVE models. The GHG emissions scenarios E3 developed for the Alliance highlighted the gap between the GHG reductions that would be possible with proposed state and federal policies and the reductions necessary to meet established federal targets. E3 also modeled the emissions impacts of the collective actions that would help bridge that gap.
