ИСТИНА

Due to a lack of better indicators, reduction in energy intensity of national economies typically is used as a proxy for improvements in energy efficiency at the national or global level. Energy intensity is calculated as units of energy consumed per unit of economic output, or gross domestic product (GDP), [kg.o.e / $]. Changes in energy intensity can reflect changes in energy efficiency of an economy, but they also reflect the impact of other factors, such as structural changes in the economy to less energy-intensive activities and the effect of fuel substitution.
