Methods, including service methods, articles of manufacture, systems, articles and programmable devices provide a conservation modeling engine framework. Programmable conservation modeling engines in communication with different customizable resource conservation modules, each resource conservation module customized to a distinct resource, select one of the modules customized to a resource identified for conservation, and user-defined criteria as a function of the identified resource and the selected module. Input data is selected and collected as a function of the resource identified and the selected module and used to weight the input data. Different optimized conservation plans are created as a function of the weighted input data and the selected module, each of the optimized conservation plans displayed having a different implementation cost, a different time for implementation and a different total amount of the identified resource saved.
