Environmental Benefits

The production of energy at the plant level is directly related to the benefits deriving from the use of renewable sources which, as a consequence, are helping the environment by saving harmful gas emissions and thus accelerating the ecological transition for a more sustainable future. At the plant level it is always possible to find the details of the quantity of Greenhouse Gases Avoided and of the Environmental Benefits and, for the reasons listed above, we want to provide maximum transparency in how our indicators are calculated:

Greenhouse Gases

They indicate the quantity of greenhouse gases avoided and are calculated taking as a reference the lifetime energy produced by the plant and specific multipliers. The latter change based on the geographical area in which the plant is located and are based on the United States Department of Energy (DOE) state-wide, or the International Energy Agency (IEA) country-wide averages.

There are three different multipliers, one for each type of greenhouse gas listed:

• Carbon Dioxide (CO₂) = [Lifetime Energy] * [CO2 Multiplier]
• Nitrogen Oxide (NO_x) = [Lifetime Energy] * [NOx Multiplier]
• Sulfur Dioxide (SO₂) = [Lifetime Energy] * [SO2 Multiplier]

You can find the details of the multipliers, for each geographical area, in the .PDF file down below.

Environmental Benefits

They indicate the amount of environmental benefits achieved and are calculated taking as a reference the lifetime energy produced by the plant and, in some cases, specific greenhouse gases multipliers. The result of the latter operation is then divided or multiplied by a global constant, which changes accordingly to the benefit, based on the sources of the Rocky Mountain Institute (RMI):

• YACP (Yearly Average Car Pollution) = { [Lifetime Energy] * [CO2 Multiplier] } / [4534.395]
• YPC (Yearly Powered Computers) = [Lifetime Energy] / [130]
• TVWH (TV Watching Hours) = [Lifetime Energy] * [6.95]
