Most energy tools give you one number and stop there. PowerSense shows you where energy is escaping your home, explains the reason behind each leak, and gives you a ranked plan to fix it. Free, no signup, takes five minutes.
Enter basic details about your home — size, heating and cooling system, insulation type, and which appliances you use most. No account needed, nothing stored.
PowerSense calculates your monthly energy consumption, dollar cost, and carbon emissions using real data from the U.S. EIA and EPA. Every formula is explained.
Your results show a ranked breakdown of every energy leak in your home, the engineering reason behind each one, and a clear action plan with estimated savings.
Other calculators give you a single CO2 figure and move on. PowerSense breaks down exactly where energy is escaping your home, explains why using real engineering principles, and ranks your fixes from highest to lowest impact.
Residential buildings are one of the largest sources of greenhouse gas emissions in the country. Most of that waste is preventable with simple, affordable changes.
American households collectively waste hundreds of billions of dollars annually on energy that escapes through poor insulation, inefficient appliances, and bad habits.
Over a third of the energy the average household pays for is lost through drafty windows, old HVAC systems, and appliances running inefficiently in the background.
With targeted improvements from a proper home energy audit, most households can cut their energy bill significantly without major renovations or large upfront costs.
