§ The fuel question

Electric cars can save you money. What you pay depends on where you plug in.

Select a vehicle, then adjust the sliders to see annual fuel costs side by side.

§02 The carbon question

Grid: California (CAMX) · 0.49 lb/kWh

Tailpipe only: counts CO₂ from gasoline combustion (19.6 lb/gal, EPA). EV grid emissions already include generation upstream, so this comparison slightly favors gas.

Even on a dirty grid, an EV still burns about half the carbon of a comparable gas car.

§ Methodology & sources

Efficiency based on EPA ratings. Gas MPG uses class‑equivalent ICE vehicle for fair comparison.
Carbon intensity is regional generation‑mix average (eGRID subregion). Gas tailpipe CO₂ = 19.6 lb/gal (EPA).
