How We Come Up With The Numbers
After doing much research we came up with a simple conversion. Using data about energy usage of household electronics from the Lawrence Berkeley National Laboratory (LBL), we figured out how to convert watts to pounds of carbon dioxide (CO2) and carbon (C).
Again, the number of pounds that we find with these equations is energy that would have been used had the device in question been turned off, or in "standby mode."
Variables:
h = number of hours the device was unplugged
w = number of watts of the item
k = number of kwH
d = number of pounds of carbon dioxide
c = number of pounds of carbon
Formulae:
- To Find Pounds CO2:
- To Find Pounds C:
Many thanks to helpful science teachers for helping with this conversion. Thanks also to the LBL for that chart, which can be found here.
