Annals of the „Constantin Brancusi” University of Targu Jiu, Engineering Series , No. 4/2018 69 NON-POLLUTING POWER SUPPLY SOLUTIONS FOR HOMES Tătar Adina, “Constantin Brâncuşi” University of Târgu-Jiu, ROMÂNIA Mihuţ Nicoleta, “Constantin Brâncuşi” University of Târgu-Jiu, ROMÂNIA ABSTRACT: Economic development and living standards are correlated with an accelerated increase in energy consumption. Considering the way of electricity production in Gorj County, the main sources of air pollution are the Rovinari and Turceni Thermal Power Plants, respectively the lignite mining operations in the area's quarries. Plants have their own contribution important as the generation of dust (deposits of slag and ash, traffic, dust, fly ash (powder suspended - aerosol sediment particles), and the emission of gaseous pollutants (SOx, NOx, CO and CO 2 ), unburnt gases and soot. Knowing the negative impact of pollutants on health, this paper aims Finding a solution supply electricity nepoluantǎ housing or with a small wind turbine. Also, after establishing the technical details of the required wind turbine, the plant cost is assessed and the investment period will be amortized. KEY WORDS: wind turbine, emitted substances, electricity, atmospheric pollution, wind. 1. INTRODUCTION The most well-known impacts on health are related to ambient air pollution, poor water quality and poor hygiene. Knowing and determining environmental risk factors is of particular importance and is the most valuable activity for promoting and preserving the health of the population. Thermoelectric power stations that use coal as a fuel have a complex impact on all environmental factors in the surrounding area (atmosphere, water, soil, flora, fauna, etc.) that the energy sector is considered the main source of pollution. Baskets of industrial installations are the most important sources of pollutant release in the surrounding atmosphere. Spreading them in all directions, especially rapid deviation to the ground, takes place at high wind speeds, while at low intensity movements, fine impurities from the chimneys can move horizontally to long distances. Of the meteorological factors that determine the dispersion of pollutants, decisive are the wind, characterized by direction and speed, and the thermal stratification of the atmosphere. Taking into account the effects of air pollution on population health, ie irritant, fibrous, carcinogenic, teratogenic, mutagenic and indirect effects highlighted by changes in urban topoclima, flora, vegetation, on the living conditions of the population, it is proposed to supply renewable energy of a dwelling. Renewable energy is the energy obtained from inexhaustible natural resources, which are constantly regenerating at very short time intervals. The importance of obtaining electricity from renewable sources has increased lately, especially due to the combination of two factors: increasing the total amount of electricity required and the current ways of obtaining it with harmful impact on the environment. The predominant use of fossil fuels to generate electricity pollutes the environment with the huge amount of carbon dioxide resulting from combustion, risking an irreversible climate change. In order to avoid the disastrous consequences of the
