Short description of EnCalcEU 5.1: EnCalcEU calculates the cost of electricity, allowing the cost based on meter readings and forward prediction based on the readings and elapsed time. The results can be saved log files. EnCalcEU copes with different charging rates for electricity, alternative rates based on a threshold, varying tax rates, discounts and fixed charges. Also calculates the amount of CO2 generated. Requires a registration code (free for personal non commercial use).
