Energy Balance The basic tool of energy analysis is the energy balance table. The columns of the table show different energy forms such as petroleum products, electricity and traditional fuels. Domestic prod + imports-exports+ stock changes- conversion inputs =domestic consumption 6/9/2018

Energy Balance Energy balances are often displayed in physical units (KWh, TOE, GJ, etc.). The unit desirable is single unit. The example given are: 6/9/2018

Reference Energy System (RES) RES is useful way of conceptualizing the use of energy in a national economy as a network. The links represent specific uses such as transformation and production of different energy forms. The most used is the RES. RES serves not only as the graphic representation but also as analytical framework for demand analysis. 6/9/2018

Reference Energy System (RES) RES was originally designed in early 1970s as tool for technology assessment in the USA, but it has been widely used for energy assessment and energy planning and policy studies. Energy system once viewed as network of energy flows, the optimal flow of energy in such a network can be used for mathematical modeling techniques in network analysis. 6/9/2018
