  2. 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

  4. 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. 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.

  7. 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.
