I built EcoEnergyCalc because I kept seeing people struggle to answer simple questions like "how much does it cost to run my AC?" or "would solar panels actually save me money?" — and the answers were buried in spreadsheets or behind paywalls. So I built 20+ free calculators covering energy costs, solar ROI, carbon footprint, heating vs cooling, LED savings, water usage, and more. All based on EPA, EIA, and NREL data. No signup, no paywall, instant results. Would love any feedback on which calculators are most useful or what's missing!

@canghun Love the no-signup angle — removing friction for something this practical is smart. The mix of financial and environmental calculations makes sense since most people care about both, even if they lead with one. What's been the most surprising calculator in terms of actual usage patterns?
