Evaluation of Global Heating Reduction Potential with the Replacement of Electricity Supplied by the Local Concessionaire Via Solar Renewable Source

ABSTRACT

Abstract The objective of this paper is to evaluate, through the 100-year Life Cycle Analysis, Global Warming Potential (GWP) and Global Temperature Increasing Potential (GTP) impact categories. It is proposed scenario of replacement of the energy matrix for the supply of electricity by Solar Photovoltaic, adopting as consumption base the facilities of Supermarkets, as they contribute to environmental impacts for greenhouse gas emissions such as intensive use of electricity, occupation large areas such as the main building or parking lot sealing the ground, the movement of customers' vehicles with air and noise pollution and the use of plastic bags. Modifying the energy matrix using electricity from renewable sources enables the reduction of greenhouse gas emissions. According to proposed scenarios for the composition of the energy matrix, based on the emission values of the Concessionaire's matrix, the result of the analysis confirms the premise that the use of renewable sources contributes to the reduction of environmental impacts, and that the substitution of Concessionaire's energy matrix for Photovoltaic Solar Energy represents a reduction in terms of kgCO2-eq, over the 100-year horizon, of 85% for GTP and 86% for GWP.
