Energy Consumption

Energy consumption is stored in the EnergyConsumption model class and models subsectors that utilize but do not produce fuels or fuel feedstocks, including:

• Carbon Capture and Sequestration (CCSQ)

• Industrial Energy (INEN)

• Stationary Combustion and Other Energy (SCOE)

• Transportation (TRNS)

• Transportation Demand (TRDE)

Energy consumption also contained the Energy Fuels (ENFU) subsector, a non-emission model subsector that contains information about fuels–both combustible and non-combustible–that are used in the EnergyConsumption and EnergyProduction models. The dimensions required for the NemoMod framework are available from the NemoMod Categories Documentation.

Modeling Concepts and Important Notes

Fuels and Heat Energy

In general, energy is produced by stationary or mobile combustion of different fuels. The combustion of fuels releases \(\text{CO}_2\), \(\text{CH}_4\), and \(\text{N}_2\text{O}\) (and other gasses, which may not be captured). These fuels are utilized by different technologies, which may use fuels at different efficiencies. Energy can also be stored (specifically electricity). The term fuel is explicitly used in all energy subsectors, while technology and storage are used in the NemoMod electricity model.

Note

Fuels are used in both non-electric energy and electric energy. However, since they are a required component of the NemoMod electricity model, variables and attributes associated with fuel are available in the Energy - Electricity section.

The combination of fuel and efficiency is an important concept for entering input data. Energy use in SCOE and CCSQ both use a fraction of energy demand at point of use to project future changes in fuel mixtures. However, many empirical data that are used rely on energy consumption, and both SCOE and CCSQ take initial consumption as inputs to SISEPUEDE.

Let

• \(D_t\) be the total energy demand at time \(t\)

• \(C_t\) be the total energy consumption at time \(t\) in question (input to model)

• \(\alpha^{(C)}_t \in \mathbb{R}^n\) be the vector of fuel mix fractions of consumption at time \(t\) for \(n\) fuels

• \(\alpha^{(D)}_t \in \mathbb{R}^n\) be the vector of fuel mix fractions of demand at time \(t\) for \(n\) fuels (input to model)

• \(e_t \in \mathbb{R}^n\) be the vector of fuel-technology average efficiencies at time \(t\) for \(n\) fuels, the demand is

\(D_t = C_t\left(\alpha^{(C)}_t \cdot e_t\right)\).

The fraction at point-of-use demand \(\alpha^{(D)}_{ti}\) for fuel \(i\) is then calculated as

\(\alpha^{(D)}_{ti} = \frac{\alpha^{(C)}_{ti}e_{ti}}{\alpha^{(C)}_t \cdot e_t}\),

i.e., the point-of-use demand is the efficiency-weighted fraction of consumption. For more information on the energy models’ mathematical specification, see the Mathematical Documentation of Energy Models.

Stationary Combustion and Other Energy (SCOE)

SCOE (**S**ationary **C**ombustion and **O**ther **E**nergy) captures stationary emissions, primarily from combustion occuring in buildings (split out by differing drivers) and allows for the specification of other fuel combustion emissions not captured elsewhere.

Note

Energy efficiency factor represents the technological efficiency for the system of heat energy delivery. Some system/fuels may conserve energy more efficiently than others.

For example, a value of 0.8 would indicate that 20% (1 - 0.8) of the input energy to the system (e.g., for heating, cooking, water heaters, etc.) is lost (e.g., 1.25 TJ of input energy satisfies 1 TJ of end-use demand), while a value of 1 would indicate perfect efficiency (1 TJ in \(\implies\) 1 TJ out)

At time \(t = 0\), the efficiencies are used to calculate an end-user demand for energy, which elasticities are applied to to estimate a point-of-use demand. In subsequent time steps, as the mix of energy use changes, input energy demands are calculated using the efficiency factors of different mixes of fuels.

Categories

Categories associated with Stationary Combustion and Other Energy are identified by the $CAT-SCOE$ variable schema element and shown in the category attribute table shown below.

Transportation (TRNS)

Transportation consists of different categories (or modes) of transportation that are used to satisfy different types of demand. In general

• Socioeconomic:

• Transportation Demand:

• Energy Production:

Known Issues

Discuss how variables that are set in Transportation have to be added to the EnergyConsumption class as well

Categories

Categories associated with Transportation are identified by the $CAT-TRANSPORTATION$ variable schema element and shown in the category attribute table shown below.

Note

These categories are associated with different Transportation Demand categories, which govern mode-shifting.

Other categories ($CAT-TRANSPORTATION$ attribute table)

Category Name	$CAT-TRANSPORTATION$	Description	Data Source	Hyperlink	Notes	$CAT-TRANSPORTATION-DEMAND$
Aviation	aviation	International and domestic civil (passenger and freight) and military aviation. Driven by demand for regional travel.				regional
Heavy Duty Road	road_heavy_freight	Private heavy vehicles primarily designed for freight transportat, including heavy duty trucks (e.g., semis). Excludes busses. Driven by freight demand.				freight
Heavy Freight Rail	rail_freight	Freight rail transport, including heavy freight and heavy passenger. Excludes light rail, trolleys, streetcars (see public transportation). Driven by growth in freight demand.				freight
Heavy Passenger Rail	rail_passenger	Heavy passenger rail, inlcuidng intra-national rail networks, high-speed rail, regional public rail, and others. Driven by demand for regional travel.				regional
Human Powered	human_powered	Biking, walking, and other forms of transportation that do not rely on fuels. Primarily driven by cycling. Demand changes driven by growth in public and private demand.				private_and_public
Light Duty Road	road_light	Transportation from public and private road-going automobiles, inluding cars and light duty trucks. NOTE: public fleets of cars (e.g., postal delivery vehicles or light-duty utility service vehicles) should be included here. Driven by growth in public and private demands.				private_and_public
Public Heavy Road	public	Road-based public transport, including busses, tolleys, light rail, and streetcars.				private_and_public
Regional Road	road_heavy_regional	Regional heavy transit driven by population growth. Primarily driven by busses.				regional
Powered Bikes	powered_bikes	Other very light transportation, including two and three-wheel motorcycles and electric bikes.				private_and_public
Water-borne	water_borne	Emissions from fuels used by domestic water-borne trips and international water-borne trips (incl. the sea, inland water channels, and lakes).				freight

Variables

Variables associated with the Transportation subsector are shown below.

Note

\(\text{CH}_4\) and \(\text{N}_4\text{O}\) emissions from mobile combustion of fuels are highly dependent on the technologies (e.g., types of cars) that use the fuels. Therefore, emission factors for mobile combustion of fuels are contained in the Transportation subsector instead of the Energy Fuels subsector. See Section Volume 2, Chapter 3, Section 3.2.1.2 of the 2006 IPCC Guidelines for National Greenhouse Gas Inventories for more information.

Trajectories of the following variables are needed for the Transportation subsector. The categories that variables apply to are described in the category column.

Transportation Demand (TRDE)

Transportation demand is broken into its own subsector given some of the complexities that drive transportation demand (unlike other subsectors, like SCOE, that do not contain categorical mode-shifting within demands). The SISEPUEDE transportation demand subsector allows for more complex interactions–e.g., interactions with industrial production, growth in tourism, waste collection, and imports and exports–to be integrated, though these are not dealt with explicitly at this time.

Categories

Categories associated with Transportation are identified by the $CAT-TRANSPORTATION-DEMAND$ variable schema element and shown in the category attribute table shown below. These categories are associated with different allowable mode shifts between vehicle types.

Transportation Demand categories ($CAT-TRANSPORTATION-DEMAND$ attribute table)

Category Name	$CAT-TRANSPORTATION-DEMAND$	Description	Data Source	Hyperlink	Notes	TRDE Variable	Freight Category
Regional Transportation Demand	regional	International and domestic civil (passenger and freight) and military aviation. Driven by demand for regional travel.				Passenger-Kilometer Demand	0
Freight Transportation Demand	freight	Demand for freight transportation. Driven primarily by growth in GDP.				Megatonne-Kilometer Demand	1
Private and Public Transportation	private_and_public	Transportation for private and public transportation–driven by people’s day-to-day commutes and transportation behavior.				Passenger-Kilometer Demand	0

Variables

Variables associated with the Transportation Demand subsector are shown below.

Trajectories of the following variables are needed for the Transportation Demand subsector. The categories that variables apply to are described in the category column.
