Revision history [back]

Here's what I know about the sources for carbon/source factors in BEopt v3:

CO2 Emissions

• Electricity: ANSI/RESNET 301, using Cambium data (long-run marginal, Low RE Cost future projection scenario, levelized from 2025-2050), averaged across all regions
• Fossil fuels: ANSI/RESNET 301, using eGRID data (combustion plus pre-combusion)

Source Energy

• Electricity: Home Energy Score, using EIA Monthly Energy Review data with Captured Energy assumptions for Renewable Energy sources
• Fossil Fuels: Home Energy Score, using I don't know what

There is no direct link between carbon and source factors, they have been developed independently. For example, the electricity carbon factors include future projections about the grid, but the source energy factors do not. It's frustrating that there is not more consistency between the various calculation methodologies.
