I will soon have 24 months of data on my electric vs. natural gas use for the 12-months before and 12-months after installing a heat pump. Does anyone know of a good Excel model to compare the energy use and energy cost with this data? Just to be clear, I will have electric solar generation therms, electric purchase therms, natural gas therms and the respective fixed and energy costs for electric and natural gas. Any help is appreciated.
