-Electricity consumption plays a major role in animal production activities and drying cereals. Like diesel, data on electricity use is not included in CAPRI. Therefore a normative approach has been chosen to quantify consumption levels.

Charges in electricity use then have been set activity-specific and to a minor extent, depending on the herd sizes. Those charges are calculated on an animal-place basis. Electricity requirements for milk cooling are based on the CAPRI milk yield. Consumption quantities are taken from literature sources and calculations of Agroscope ART in Swit-zerland (Project BW04). Electricity used in grain drying is based on a normative approach due to lack of data of drying systems in the EU. Nevertheless, consumption quantities for drying are linked to the harvest moisture content as described in Chapter 7.5.2.11. Furthermore, electricity use in greenhouses is considered. This is expressed depending on the lighting and heating efforts, as far as by using electricity. Small quantities of electricity are charged for lighting and ventilation in storage facilities for feeding stuff.+Electricity consumption plays a major role in animal production activities and drying cereals.

 +====Analysis of CAPRI energy module results====
 +
 +The results of the CAPRI energy module can be displayed in various ways and on different levels. Table 33 gives an overview. Further down, each parameter is shown in more detail.
 +
 +**Table 33: Energy module results structure**
 +
 +^Parameter ^Parameter Unit ^Description ^Availability^
 +|Energy per CAPRI activity unit|MJ/ha; MJ/head |Covers all energy requirements necessary for one CAPRI activity unit per year| Region-specific and activity-specific; weighted averages on NUTS-0 and EU level|
 +|Energy per CAPRI output unit|MJ/kg|All energy requirements for one CAPRI activity unit are divided by the output level; allocation between main product and by-products is carried out for a number of activities| Region-specific and activity-specific; weighted averages on NUTS-0 and EU level|
 +|Energy efficiency – Type “energy”|MJ/MJ|The output level of a CAPRI activity is assessed by its energy content (See Chapter 7.5.3) whereas allocation between main product and side-products is done for some activities. The result is divided by all energy requirements of the CAPRI activity unit. In short: Energy output (per kg) divided by energy input (per kg)|Region-specific and activity-specific; weighted averages on NUTS-0 and EU level|
 +|Energy efficiency – Type “Finance”|MJ/€|The output level of a CAPRI activity is assessed by its energy content (See Chapter 7.5.3) whereas allocation between main product and side-products is done for some activities. The result is divided by the income for the activity. |Aggregated on NUTS-II, NUTS-0 and EU level|
 +|Energy balance |MJ|The output level of all CAPRI activities of a region are assessed by its energy contents (See Chapter 7.5.3 FIXME) whereas allocation between main product and side-products is done for some activities and then sum up over the region. The input energy requirements for all CAPRI activities are multiplied with the relevant activity levels and then sum up over the region. The result shows energy requirements (INPUT) and energy output (OUTPUT). Imports and exports of energy can be shown separately.|Aggregated on EU level|
 +|Energy requirements-overview|MJ/ha; MJ/head|On an activity-based, regional level, the composition of total energy requirements can be shown on an aggregated level.|Region-specific and activity-specific; weighted averages on NUTS-0 level|
 +|Energy requirements-detail|MJ/ha; MJ/head|On an activity-based, regional level, the composition of total energy requirements can be shown on in detail. |Region-specific and activity-specific; weighted averages on NUTS-0 level|
 +|Energy input units|Input unit/ha; Input unit/head|On an activity-based, regional level, the composition of input units driving the energy needs can be shown in detail.|Region-specific and activity-specific; weighted averages on NUTS-0 level|
 +|Energy content products|MJ/kg product |On an activity-based level, the energy content for products can be shown; energy assessment of output is based on this parameter; Energy content is assumed being equal throughout all NUTS-II regions.|Activity-specific|

 +===Application notice===
 +
 +Basically, the energy module is designed as post-model analysis. This implies, that the energy module can be run independently from the CAPRI core model. Nevertheless, a number of energy parameters depend on CAPRI data that changes depending on the scenario and the time under consideration. Consequently, the energy module has to be run each time changes in a scenario result table occur. Having set changes in any of the energy module`s files, the  GAMS-file “enerind_bas” has to be run. To transfer such changes in the energy module to the scenario tables, the GAMS-file ”enerind_calc” has to be run in each scenario mode.
 +
 +===Structure of output tables===
 +
 +A broad range of output tables permits to display results of the energy indicator. Some of those are presented in this chapter. Figure 41 shows some examples for display modes of the energy indicator.
 +

 +Taking Example 1, the results of the energy consumption overview table are shown. This can be explored within the scenario exploitation table. Beside “Total MJ”, which indicates energy consumption per ha or head, a number of energy consumption categories such as diesel, electricity, machinery, fertiliser, young animals, seed and plant protection can be displayed either on a MJ basis or in metric units. Furthermore as can be seen in Example 2, detailed data on energy consumption can be displayed if required. Data on feeding stuff, housing systems, grassland use, tillage systems, machinery use, irrigation, greenhouse use, seed, plant protection, drying etc. can be shown activity- and region specific. Beside regarding the area or the animal, the product can be chosen as a reference point. As shown in Example 3, energy requirements per kg of product (expressed in MJ/kg) and domestic en-ergy efficiency (expressed in MJ/MJ) can be shown. On a sectoral basis, efficiency related to the in-come (expressed in MJ/€) is displayed. A sectoral balance can be extracted as shown in Example 4 summing up all energy requirements and all energy output.
