Abstract
To explore the potential energy impacts of widespread PHEV use, an innovative, three-part survey instrument collected data from 877 new vehicle buyers in California. This analysis combines all the available information from each respondentâdriving, recharge potential, and PHEV design prioritiesâto estimate the energy impacts of the respondentsâ existing travel and understandings of PHEVs under a variety of recharging scenarios. Results suggest that the use of PHEV vehicles could halve gasoline use relative to conventional vehiclesâthe majority of this reduction being due to increases in charge sustaining (CS) fuel economy. Using three scenarios to represent potential boundary conditions on PHEV driver recharge patterns (unconstrained, universal workplace recharging, and off-peak only charging), we estimate tradeoffs between the magnitude and timing of PHEV electricity use. In the unconstrained âPlug and Playâ recharge scenario, recharging peaks at 6:15 p.m., following a far more dispersed pattern throughout the earlier part of the day than anticipated by previous research. PHEV electricity use could be increased through policies increasing non-home recharge opportunities (e.g., the âEnhanced Workplace Accessâ scenario), but most of this increase occurs during daytime hours and could contribute to peak electricity demand (depending on a given regionâs definition of âpeakâ). We also demonstrate how deferring all recharging to off-peak hours (8:00 p.m. to 6:00 a.m.) could eliminate all additions to daytime electricity demand from PHEVs. However, in such a scenario less electricity is used due to the elimination of daytime recharge opportunities and less gasoline is displaced. Overall, policy, technology, and energy providers may use this information to understand whether their plans, designs, and goals align with these present empirically informed understandings.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
