CleanEnergyMath.com ("this site") provides a free calculator for comparing the cost of charging an electric vehicle at home against fueling a gas vehicle. This page explains what data is collected when you use the site and how it's used.
Zip codes and slider values you enter into the calculator are sent to this site's server-side lookup function solely to retrieve local electricity and gas price estimates. This data is not stored, sold, or associated with your identity.
