What is LB MWh?
values such as pounds per megawatt-hour (lb/MWh) of emissions, which allows direct comparison of the. environmental attributes of electricity generation.
What does eGRID stand for?
What is eGRID? The Emissions & Generation Resource Integrated Database (eGRID) is a comprehensive inventory of environmental attributes of electric power systems.
What is eGRID subregion?
Enter eGRID, The Emissions & Generation Resource Integrated Database, which is a comprehensive inventory of environmental attributes of electric power systems throughout all subregions of the United States.
How is energy produced?
Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.
What is grid mix?
The Grid Mix. Each state has a different grid mix that determines the emission expense of an EV. One state’s primary electricity source could be natural gas or hydro-power. Another’s could be coal or nuclear plants.
What is grid emission factor?
A “grid emission factor” refers to a CO2 emission factor (tCO2/MWh) which will be associated with each unit of electricity provided by an electricity system. It is a parameter to determine the baseline emissions for CDM projects in the renewable energy sector (hydro, wind, solar PV, and geothermal power, etc.)
What is the current energy mix?
About 61% of this electricity generation was from fossil fuels—coal, natural gas, petroleum, and other gases. About 20% was from nuclear energy, and about 20% was from renewable energy sources.
