Gross available energy by product [ten00121]

The Gross available energy is one of the most important aggregate of the energy balance. For the total of all energy products this is the total energy delivered/consumed in a country. However, for individual products its interpretation is different. For primary products (those directly harvested from nature) it shows the available supply. For derived products (manufactured products, secondary products) it covers only their international trade and stock changes. Production of derived products is recorded in the transformation output. Consequently, Gross available energy for derived products can be negative - which means its original primary form of supply was accounted for in the form of the respective primary product.
