## 30-57 DISIPAREA DE MATERII ȘI ENERGIE – POLUAREA MEDIULUI UN SISTEM BINOMIAL

MATERIALS AND ENERGY DISSIPATION –
ENVIRONMENTAL POLLUTION A BINOMIAL SYSTEM
The goods production and consumption is followed by a huge
dissipation of raw materials and noble energies transferred as electrical and
mechanical work. The paper analyses electrical energy production using the
particular efficiencies for the conversion chain of a thermal power plant, using
the fossil fuels. Additionally, the losses in the transport and distribution of
electrical energy, with more tension stages are also evocated. We have divided
the chain in three stages: the raw fuel extraction and transport, the power plant
and the electrical transport and distribution system. For each module the
efficiency was shown and the final efficiency to the consumer was related to the
heating value of the extracted fuel at the ore. Based on values of the
efficiencies, the process and the equipment with high losses were identified.
The impact of these losses on the surroundings was mentioned.
