What is energy intensity?
A measure of how efficiently a country is using its energy. It is calculated as units of energy per unit of GDP. A high energy intensity indicates a high price or cost of converting energy into GDP. It is generally recognised that energy intensity decreases with economic development: energy is used more efficiently and so the cost per unit of GDP becomes less.
