You enter your annual energy use in universal units — MWh of fuel/heat and MWh of electricity (and m³ of water). Each selected practice applies its published savings range (sourced on the practices page — DOE, LBNL, Energy Star, Envirowise) to the relevant energy base. The primary result is energy saved in MWh — independent of price. Money and CO2 are then derived from YOUR currency, YOUR price per MWh and YOUR emission factor, all editable, because prices move and emission factors differ by grid and fuel.
