Base on our green home report, it is not so bad. We found that the 3 energy wastage are based on these items, 1.Computer, 2. Air-condition and lastly the Fan. So, for the first week(7-13/4/12), we tired to reduce from using all these items and we did continue it for the rest of the days, and when 21/4/12, we did calculate on My Carbon Foot Print, our averaged carbon foot had reduced to 4.67. We also did the waste separation and so on and so for.
