ev-vs-gas
Compare an EV against a comparable gas car on total cost — upfront gap after incentives, energy vs fuel per year, maintenance delta, and the crossover year when the EV pulls ahead (or doesn't). Use when asked is an EV worth it, EV vs gas total cost, when does an EV pay for itself, or should my next car be electric. Produces the year-by-year cumulative comparison from the script, the crossover year, the per-mile energy math, and the honest not-modeled list.

# EV vs Gas Skill The EV question is a crossover question: a higher price tag melting under lower running costs, with the answer living in *your* numbers — miles driven, electricity price (home vs. public charging are different products), and how long you keep cars. This skill runs the cumulative math year by year and reports where the lines cross, then is honest about what the model can't see: battery risk, a resale market still finding its feet, and the charger install that belongs in the purchase price. ## What This Skill Produces - **The cumulative table** — EV vs gas total cost per year over the horizon, from the script - **The crossover year** — where the EV pulls ahead, or the finding that it doesn't within the horizon - **The per-year energy math** — miles ÷ efficiency × price, both sides, shown not asserted - **The not-modeled list** — battery, resale, charger install, price drift — stated up front ## Required Inputs Ask for these if not provided: - **The two candidates' prices** — the actual EV and the *comparable* gas car (same class — comparing a luxury EV to an economy gas car answers a different question); applicable incentives, flagged as verify-eligibility - **Annua

What does the ev-vs-gas skill do?
Compare an EV against a comparable gas car on total cost — upfront gap after incentives, energy vs fuel per year, maintenance delta, and the crossover year when the EV pulls ahead (or doesn't). Use when asked is an EV worth it, EV vs gas total cost, when does an EV pay for itself, or should my next car be electric. Produces the year-by-year cumulative comparison from the script, the crossover year, the per-mile energy math, and the honest not-modeled list.
How do I install it?
Run `npx skills add mohitagw15856/pm-claude-skills --skill ev-vs-gas --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From mohitagw15856/pm-claude-skills, a repository with 1,255 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
