Energy France - Find where to act first on your home energy costs

by•
Energy France is a free home energy diagnostic built for households in France. Answer a few simple questions about your home and energy use, and get a personalized ranking of where to look first: electricity & gas, heating, or solar. No account, email, or phone number required. This is an early prototype, and we're launching it to learn from real users and improve the recommendations.

Hi Product Hunt! 👋 I built Energy France around a simple question: when a household feels its energy costs are too high, where should it look first? Instead of immediately pushing an offer, the prototype asks a few questions about the home and energy usage, then ranks three possible areas to explore: electricity & gas, heating, and solar. The project is still at an early validation stage. There is currently nothing to buy, and the diagnostic doesn't ask for a name, email, or phone number. What I'm looking for most from this launch is feedback: Was the diagnostic easy to complete? Did the ranking make sense for your situation? And what would make the result genuinely more useful? Thanks for testing it — critical feedback is very welcome.

GPT-6 Astra made it practical for me to turn Energy France from an idea into a working, instrumented public prototype in a very short iteration cycle. It helped across the end-to-end build workflow: reasoning through product requirements, implementing and reviewing the diagnostic experience, adding privacy-conscious funnel analytics, testing the implementation, and deploying iterations while preserving the existing deterministic scoring logic. Instead of using AI as the consumer-facing decision engine, I used Astra as an engineering and product-building agent to accelerate the path from concept to a measurable real-world experiment.
