LED floodlight to replace HID lamp
Comparison
CO2 emission
CO2NOxSOx
When fuel combust in a gas turbine or steam boiler of a power plant to produce electricity they release energy which is measured in kilowatt-hours (kWh) and a mass of carbon dioxide gas.The amount of energy that they liberate and the amount of carbon gas they give off in the process are both proportional to the amount of fuel that burns
in USA calculated the emissions from electricity generation based off figures from the EPA’s (environment protection agency) eGRIDemission factors based on 2009 and 2012 data On average, Electricity sources emit 0.75 kg to 2.69 kg CO2 per kWh (depend on different fuel type & combustion type)
When a 100 watts of lamp is activated for 10 hours per-day in 365 days we can calculate the CO2 emission minimum as follows = 365 x 10 x 100 :1,000 x 0.75 = 274 kg of CO2
