Document Summary
Special treatments of some entries in the energy balance. Total energy content is measured rather than the available energy, electricity generated from hydroelectric power, nuclear power or geothermal, the available energy is essentially measured -> inconsistency. Consumption equivalence - record direct heat equivalent of the electricity (converting 1 kwh to kcal or kj using calorific value of electricity, 1 kwh = Production equivalences - measure equivalent or comparable fossil fuel requirement of primary electricity production - premise of consistency in approach. Estimated amount of fossil fuel input that would be required to provide same energy as produced by primary electricity sources. Two step procedure to determine the input primary energy requirement. Overall thermal efficiency of thermal power generation for the country concerned is est first. Efficiency applied to primary electricity generation to arrive at the input energy requirement. Normally countries with high hydro or nuclear energy tend to use production equivalence concept, while others tend to use consumption equivalence concept.
