Green Light New Orleans is a 501c3
non-profit organization
EIN 20-8151937
Calculations for Energy savings :
| Energy Cost per KWH (March 2006, Entergy New Orleans) | $0.118 |
| One 15w light bulb used 24hrs/day for one year (8,760 hrs) saves 394.2 KWH (source: Entergy New Orleans lighting calculator) | $46 |
| Most 15w light bulb last 10,000 hrs. Savings: 450 KWH | $53 |
Calculations for CO2 emission reduction:
EPA recommends to use the value for the subgrid from the eGRID database. The value for the SERC Mississippi Valley subregion (our region) from the latest eGRID data (for the year 2004) is 1135 lb/MWh (1 MW = 1000 kW), which is equivalent to 0.515 kg CO2/kWh, the most widely used measure.
394 KWH = 447lb CO2
1 CFL = savings of 394KWH = $46 = 447 lb of CO2
The international reporting standard for CO2 emissions is in metric tons. Since there are 2204.62 lbs per metric tonne, a single ton of carbon dioxide equates to 2204.62 pounds of CO2.
Our main focus is environmental. The savings
posted on sections of this web site are on purpose a low estimate (We install bulbswith an average 10,000 hr life time but we only calculate 8,760 hrs).
The savings might be higher than stated on the web site. Thank you
for your support!
