Energy Intensiveness of Manufacture of Selected Products

Methodology

Contents

Under the term consumption of fuels and energy for production of selected products there is understood final consumption of fuels, heat and power before they are brought to appliances in which comes to the exploitation of their final useful effect so that another type of registered fuels and energy kind no more arises, with exception of secondary energy sources.

From the final consumption of fuels and energy there are excluded charges into the energy process and direct operational consumption of the energy process.



TABLE OF PRODUCTS - ITEMS

1st row
- Product´s title
- Energy code - is identical with the code used for products of the industrial statistics department no. 321 CSO relating to statistical reports Prům P 2 - 12 and Prům P 3 - 12 valid for the period 1985-1993.
- Specific unit - S P U - physical specific unit for a product´s production (t, m3, th. m2, th. m3, m3 a.a = m3 absolute alcohol etc.)
- Code of industry 95 outgoes from SKP; eg. the first six digits form actually SKP code appearing with items lacking Prům. 1995 code. Classification of products in the industrial statistics department underwent annual changes in the period 1996 - 1998.

2nd row: Production
- Total annual production of a product measured in specific physical unit SPU.

3rd and 4th row: Consumption of electricity
- Total consumption - Total annual electricity consumption (MWh)
- Specific consumption - eg. total consumption/production; calculated in kWh/SPU

5th and 6th row: Consumption of heat
- Total consumption - Total annual consumption of heat (GJ)
- Specific consumption - eg. total consumption/production (GJ/SPU)

7th and 8th row: Consumption of fuels
- Overall consumption - Total annual consumption of fuels (GJ)
- Specific consumption - eg. total consumption/production (GJ/SPU)

9th and 10th row: Occurrence of secondary energy sources
- Emergence of energetically utilizable waste heat arising during production process, total (GJ)

- Emergence of directly energetically utilizable secondary fuels arising during production process, total (GJ) - (for instance top gas or nitrogen rich gas, biogas, combustible wastes etc.)

11th and 12th row: Consumption of energy, total energy consumption
- Total consumption (total) - total annual energy consumption (GJ)
Specific consumption - eg. total consumption/production (GJ/SPU)

Explanation: SPU - Specific Physical Unit

Comment: Items relating to secondary energy sources were surveyed till 1989

Explanations concerning definitions and conversions of units with some items (bricks, roofings and fabrics) are cited on page 31.

Guiding tables for processing, eg.
Table 1: - Consumption of fuels, heat and electricity for the production of selected products – year 2004
Table 2: - Specific consumption of fuels, heat and electricity for the production of selected products – year 2004 are shown on pages 87 and 88.
