Environmental

The environmental metrics come from the EPA Greenhouse Gas Equivalencies Calculator. All the values are structured on a per kWh basis. For example, 1 kWh of electricity is equal to 1.6 pounds of Carbon Dioxide emissions. In the financial template, setting the Carbon Dioxide field to 1.6 equivalent then your HelioScope reports will show 1.6 x system kWh generation to calculate the total carbon dioxide offset in pounds. The table below provides the per kWh equivalencies in both metric and imperial units.
