Abstract
Efforts to improve air quality and concerns about global warming make transportation mediums that do not produce emissions more attractive to end users. Meanwhile, some of these transportation mediums are powered by an electricity grid that generates a great deal of emissions. This study compared the greenhouse gas GHG emissions for both electric and fossil-powered vehicles using estimates of tailpipe emissions of fossil-powered vehicles and the indirect emissions from the electricity grid. Furthermore, a system dynamic model was developed for a more holistic review of the GHG emissions for both electric and fossil-powered vehicles. The result indicated that in terms of associated emissions from the grid, electric-powered vehicles are not always better than fossil-powered vehicles when the electricity is not from a renewable source. The GHG emissions for electric-powered vehicles are dependent on both the electricity usage rate of the vehicle and the GHG emissions that are associated with the production of that amount of electricity. Further opportunities exist in renewable and clean energy technologies for various operations. Based on reports from previous works, this report also presented potential strategies to achieve a significant reduction in GHG emissions for both the electricity grid and fossil fuel refining processes.

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 it
