Hi.
In the attached sheet, I have logged my gas energy consumption (kWh) from 2006 to 2012. I want to analyse my relative consumption over time, on a monthly basis.
However, the bills have been generated by different suppliers for irregular periods (eg. 10-May-2006 to 24-Jul-2006, or 23-Feb-2010 to 6-Mar-2010). So, how can I re-tool my sheet to arrive at rough figures that can be allocated against each month?
Or, if there is no dependability about that method, do you have better suggestions for formulae which allow for effective comparison over time? Let's say, daily?
Thank-you.
