The calculators provide tools for a preliminary assessment of key technical, financial, and environmental characteristics for renewable energy projects and energy efficiency measures. Typical input information for typical fuels, technologies and system parameters are presented to facilitate initial estimations, if no relevant project information is available. These initial input data should be replaced with specific project information upon its availability.
