Energy intensity is a measure of the energy efficiency of a nation's economy. It is calculated as units of energy per unit of GDP. 1  High energy intensities indicate a high price or cost of converting energy into GDP. 2  Low energy intensity indicates a lower price or cost of converting energy into GDP. Energy Intensity as defined here is not to be confused with Energy Use Intensity (EUI), a measure of building energy use per unit area. It is calculated as units of energy per unit of GDP. 1  High energy intensities indicate a high price or cost of converting energy into GDP. 2  Low energy intensity indicates a lower The most eminent example of this is the energy intensity of GDP (gross domestic product) or energy consumption per GDP. Energy intensity of GDP is easy to calculate and is often used as an energy-conservation index for a country. Figure 3 shows primary energy intensity of GDP after distributing energy consumption of the energy conversion sector in proportion to the electricity demand of the industrial and non-industrial industries (Japan = 1). 1 Light-duty vehicle energy intensity, which is measured as their consumption divided by the number of vehicle-miles traveled, is projected to decline by more than 47% from the 2005 value. 1 Light-duty vehicles are by far the largest energy consuming part of the sector. 2  The indicator could be called “aggregate energy intensity” or “economy-wide energy intensity”. The term “energy intensity” is also used for ratios of energy use by the different economic activities to output. The ratio of energy use to GDP indicates the total energy being used to support economic and social activity. (c) Limitations of the Indicator: The ratio of aggregate energy use to GDP, often called “energy intensity” or the “energy ratio”, is not an ideal indicator of energy efficiency, sustainability of energy use, or technological development, as it has been commonly used. Measuring Building Energy Use. Knowing how to measure energy use in buildings will help you set better energy efficiency goals. Energy Use Intensity (EUI) normalizes energy use by floor area and is useful for targets and benchmarks. 1 kWh of site electricity from a solar panel on the building's roof is equal to 1 kWh of source energy, because the solar panel itself is the source. The energy intensity values in the tables above only consider the amount of electricity and fuel that are used on-site (secondary or site energy). In the United States, energy intensity has been declining steadily since the early 1970s and continues to decline in EIA's long-term projection. A country's energy intensity is usually defined as energy consumption per unit of gross domestic product (GDP). Greater efficiency and structural changes in the economy have reduced energy intensity. From 1950 to 2011, energy intensity in the United States decreased by 58% per real dollar of GDP. 1 Light-duty vehicles are by far the largest energy consuming part of the sector. 2  Light-duty vehicle energy intensity, which is measured as their consumption divided by the number of vehicle-miles traveled, is projected to decline by more than 47% from the 2005 value. (b) Brief Definition: Ratio of total energy use to GDP: ratio of energy use by economic activity to value added. (c) Unit of Measurement: Tonnes of oil equivalent per unit of local currency or per US $ (d) Placement in the CSD Indicator Set: Economic/Consumption and Production Patterns/ Energy Use. 2. (c) Limitations of the Indicator: The ratio of aggregate energy use to GDP, often called “energy intensity” or the “energy ratio”, is not an ideal indicator of energy efficiency, sustainability of energy use, or technological development, as it has been commonly used. From Wikipedia, the free encyclopedia. The following is a list of countries by energy intensity, or total energy consumption per unit GDP, as published by the World Resources Institute for the year 2003. It is given in units of tonnes of oil equivalent per million constant year 2000 international dollars. The energy intensity is the ratio of primary energy consumption over gross domestic product measured in constant US $ at purchasing power parities.
