~40% of our grid runs on natural gas, and Henry Hub spot is up 21% since Feb 28. Fuel cost flows through to retail rates with a 3-6 month lag, so the bills we're is what I think are priced against February.
I hacked together a free tool that takes your address and shows the actual exposure, plus whether your roof is any good for solar.
Florida runs ~70% on natural gas. Gas prices are up 21% since the Iran strike in February, which filters into residential bills with a 3-6 month lag. FPL's March rate increase sits on top.
Built a free tool that takes your address, pulls your roof from Google, and shows:
- How much extra the gas spike is adding to your bill
- Whether your roof is any good for solar (pitch, direction, shading)
- 25-year savings math with the 30% federal tax credit

Hi. I built this over a couple weekends, trying to see how much of the post-Feb-28 energy (Iran Strike) spike actually maps to individual homes < hormuzsolar.com >
Data sources: Google Solar API (roof geometry, panel layout, annual kWh), EIA Short-Term Energy Outlook (Apr 2026, for WTI/HH price tracking), 242 utility rate filings via state PUC public records.
Stack: Next.js 16, Three.js for the Earth zoom, D3 + GSAP for the shipping-map scene, Supabase for storage. Bill impact % is a weighted blend of WTI and Henry Hub deltas from the Feb 27, 2026 pre-strike baseline. Methodology is on-site under "How we calculate this."
Happy to take methodology critique.
Built a fun tool that quantifies post-Hormuz residential electricity exposure at the address level. Pre-Feb-27 WTI/HH as the baseline. (obviously estimations)
