(c) Limitations of the Indicator: The aggregate indicator for the agricultural sector 
(ISIC, Division A, groups 01, 02, 07, 08 and 09) reflects the energy intensity for all 
agricultural activities (crop and livestock production, forestry, fishing, etc.). Changes 
in this aggregate indicator are due to changes in both energy efficiency and the 
product mix of agricultural output (structure). This means that differences seen across 
countries in both the absolute level and the time development of this indicator do not 
necessarily reflect differences in energy efficiency. Furthermore, agricultural 
production is affected by factors other than energy inputs (e.g. climate, availability of 


58 
other inputs, etc). These factors are less distorting if comparative values are collected 
for consecutive years. Data for energy use in agriculture are not considered to be very 
reliable at the present time. Special surveys could generate sound data but would be 
expensive and might not be a priority for statistical agencies. 
(d) Alternative Definitions/Indicators: An alternative indicator is energy use per 
unit of agricultural output. While data for production are available, it is problematic to 
find data on energy use disaggregated for specific forms of agricultural activity. The 
indicator includes combustible renewables and waste (CRW) but not such non-
commercial energy inputs as human and animal power. Human power quantification 
methodologies might need to be further elaborated. 
ASSESSMENT OF DATA 
(a) Data Needed to Compile the Indicator:
• Total final energy use by the agricultural sector. 
• Electricity consumption by the agricultural sector. 
• Value added of the agricultural sector. 
(b) National and International Data Availability and Sources: Some data are 
available for most countries, although reliable and comprehensive statistics to enable 
time-series analysis are elusive. Agriculture value-added data are compiled by the 
World Bank. Agricultural production figures are available from agriculture ministries. 
The FAO has processed and compiled considerable data on agricultural sector outputs 
in physical terms. The United Nations compiles value added at the two- and three-
digit level in the agricultural sector. The energy balances of the International Energy 
Agency (IEA) include energy use in agriculture. Energy balances are prepared by 
energy ministries or other competent national authorities. Regional data are available 
from regional organizations such as the Organización Latinoamericana de Energía 
(OLADE).
