Calculate Reduced CO2 (with costs & interest) Apply savings to Investment LabelLabel
Power companies that burn fuel will emit Carbon Dioxide, and are taxed on metric
tons of CO2.
In addition, they have expenses to reduce, control and collect such emission. Levels of CO2 emission as measured and analyzed are shown in the following fuel selection block.
Reduction of electrical demand will reduce emission of Carbon Dioxide and other pollutants from any fuel used. To reduce taxes
and other expense, power companies can assist funding of LED lighting for the end user, and gain many beneficial years for all.
In 2010,power plants were the largest stationary sources of direct emissions
with 2,324 million metric tons of carbon dioxide equivalent (mmtCO2e), followed by petroleum refineries with emissions of 183 mmtCO2e.
The ROI-LED Calculator shows the reduced CO2 production, payback time, and both the annual and life-time
cost & savings figures for reduced energy demand of LED lighting. Reduction of CO2 emission reduces expenses and tax
for the power plant which may then provide credits toward the LED customer. This calculator will not perform properly if removed from this web site.
