A presente dissertação de mestrado avalia o papel dos sistemas fotovoltaicos na redução das emissões de carbono e sua contribuição para a neutralidade carbónica em ambientes urbanos, com foco nos acordos internacionais, como o Acordo de Paris, e nos planos estratégicos de Portugal para promover a sustentabilidade energética. Foram analisados os consumos energéticos da rede e dimensionados sistemas fotovoltaicos para infraestruturas localizadas em áreas urbanas da Câmara Municipal de Sesimbra, sendo estes locais o Parque Operacional da Fonte de Sesimbra, o Mercado Municipal da Quinta do Conde e o Parque de Campismo do Forte do Cavalo, com o objetivo de estimar e avaliar o potencial de redução da pegada de carbono ao substituir a energia proveniente da rede elétrica, onde parte é proveniente de combustíveis fósseis, por energia renovável. Adicionalmente, foram estudados os impactos ambientais, tanto positivos quanto negativos, associados a centrais solares em zonas rurais, tendo sido comparados com os impactos da descentralização energética através da instalação de sistemas fotovoltaicos em áreas urbanas. Os resultados do estudo indicam que a descentralização energética é uma estratégia promissora para o futuro da sustentabilidade energética. Esta abordagem reduz a pegada carbónica em 12,67% para o Parque Operacional da Fonte de Sesimbra, 10,32% para o Mercado Municipal da Quinta do Conde e 9,96% para o Parque de Campismo do Forte do Cavalo com um potencial de produção energética anual de 21MWh, 20MWh e 15MWh respetivamente para cada local. Além do mais, a utilização das infraestruturas urbanas para instalação de sistemas fotovoltaicos apresenta também significativamente menos impactos ambientais negativos quando comparada às centrais solares em áreas rurais tais como a perda de biodiversidade, destruição do solo e da sua geomorfologia e degradação da qualidade do ar durante as fases de construção necessária à construção das centrais. Estes resultados alinham-se com os objetivos de Portugal para alcançar a neutralidade carbónica e uma transição energética sustentável.
Abstract This master's thesis evaluates the role of photovoltaic systems in reducing carbon emissions and their contribution to carbon neutrality in urban environments, with a focus on international agreements such as the Paris Agreement and Portugal's strategic plans to promote energy sustainability. Energy consumption was analysed and photovoltaic systems were dimensioned for infrastructures located in the urban areas of Sesimbra City Council, such as the Parque Operacional da Fonte de Sesimbra, the Mercado Municipal da Quinta do Conde and the Parque de Campismo do Forte do Cavalo, with the aim of estimating and evaluating the potential for reducing the carbon footprint by replacing energy from the electricity grid, part of which comes from fossil fuels, with renewable energy. In addition, the environmental impacts, both positive and negative, associated with solar power plants in rural areas were studied and compared with the impacts of energy decentralization through the installation of photovoltaic systems in urban areas. The results of the study indicate that energy decentralization is a promising strategy for the future of energy sustainability. This approach reduces the carbon footprint by 12,67% for the Fonte de Sesimbra’s Operational Park, 10,32% for the Quinta do Conde Municipal Market and 9,96% for the Forte do Cavalo’s Campsite with an annual energy production potential of around 21MWh, 20MWh and 15MWh respectively for each location. Furthermore, the use of urban infrastructures to install photovoltaic systems also has significantly fewer negative environmental impacts when compared to solar power plants in rural areas, such as the loss of biodiversity, destruction of the soil and its geomorphology and degradation of air quality during the construction phases required to build the plants. These results are in line with Portugal's objectives to achieve carbon neutrality and a sustainable energy transition.
