House 2 - Summary Of Electricity Cost Savings

The graph below shows how daily electricity cost has varied over the last year or so. The short term variations are due to usage changes caused by the number of people in the house. Currently we are on a single tariff so there is no night time rate, we will be reviewing this at the end of the year. Having only moved in in November 2009 it is too early to read to much into these results apart from that the trend seems downwards. The large dip in July is due to holidays and the large peaks in August and September 2010 are due to visitors. The very large peak in December 2010 was caused by excessively cold temperature (-19C) when emergency electric heating was used in the chicken house and greenhouse for a few days.

This graph shows the percentage electricity cost saving by comparing costs with November 2009 to January 2010 as we currently have no history. This does mean these results will be somewhat suspect for a few more months.
