Power Consumption Calculator

Posted in Calculators, Project 360 by Jacob on the January 25th, 2010

The purpose of this calculator is to determine how your existing and/or future aquarium will impact your energy bill. This calculator is designed to work for PG&E customers or anyone on a tiered plan similar to what PG&E uses. This will work for anyone on a fixed rate plan as well you’ll just have to cheat and enter some large number (1000 for example) for your daily baseline and your fixed rate as your baseline rate.

Disclaimer: This application is designed for novel use only. By using this application you and you alone assume full responsibility for the use of the data generated herein. Ok enjoy!

Find the following information on your PG&E bill.

*non-aquarium energy only

PG&E makes it incredibly complicated to understand your energy bill with their tiered rate system. A couple of things this calculator makes more clear are: 1) It’s not really possible to know how much your aquarium related energy use costs without taking into consideration your ‘other’ non-aquarium energy use. 2) the less ‘other’ energy you use around the house the less your tank costs to run.
