To avoid getting the error “Your operating system does not meet system requirements”, I had to use User Agent Switcher to download the spreadsheet at http://office.microsoft.com/en-us/templates/TC300022771033.aspx for electric meter logging for energy efficiency. Then I used cabextract to extract the .cab file and used Open Office to view the 30002277.xltx file. Here it is saved using Open Office’s ODS format: electricity_tracking.
