Abstract : Electricity and petroleum products from crude oil (e.g., gasoline, diesel, jet, residual oil and liquefied petroleum gas) are the baseline energy products that are used in various fuel production pathways. Therefore, the energy and emissions intensities of electricity and petroleum products are critical for life-cycle analysis (LCA) of transportations fuels, or well-to-wheels (WTW) analysis. These energy and emissions intensities of electricity and petroleum products depend highly on the electricity generation mixes and the crude oil mixes to the U.S. refineries, respectively, which change over time and vary by region. Therefore, we continuously investigate and update the electricity generation mixes and the crude oil mixes to the U.S. refineries in our LCA model (namely, the Greenhouse gases, Regulated Emissions, and Energy use in Transportation [GREET®] model). For the updates of these mixes to the GREET 2016 model, this technical memo documents the data sources and the methodologies at the national and regional levels.
