ABSTRACT Energy is essential for human activities and, considering the prospect that the demand for energy increases, it is necessary to carry out studies of new technical solutions so as to make the use of the available sources feasible. Greater participation of renewable energy sources in the electrici...
ABSTRACT The increasing demand for electricity and the scarcity of resources, require renewable energy sources and efficient equipment that reduce the consumption of electricity. The Green Office (GO) of the Universidade Tecnológica Federal do Paraná (UTFPR) is a sustainable building that uses strategi...
ABSTRACT The gradual shifting of the energy matrix to renewable sources is one of the main global strategies for sustainable development. According to studies, the use of electric energy by automobiles would lead to a reduction in gasoline consumption of 40.7% in 2031, accompanied by an increase in elect...
ABSTRACT This study shows, through several analyses, ways to reduce costs with electric power in supermarkets. For this purpose, one of those establishments was visited and several data were collected for subsequent analysis. The results have shown that the combinations of several actions of energy effic...
ABSTRACT The present work presents the development of a system of measurement of electric energy consumption. This system shows the consumer the amount of energy consumed and its respective monetary value in real time. The prototype was used in a case study to validate its operation. Data were collected ...
ABSTRACT Distributed photovoltaic (PV) generation is characterized by the application of several small power plants in urban centers. This form of energy deserves special mention due to the possibility of installation in existing areas such as roofs and facades. Thus, the implementation of these systems ...
Resumo Os fenômenos envolvendo eletromagnetismo e conservação da energia durante o século XIX não se enquadravam no paradigma newtoniano vigente. Havia entre os estudiosos a necessidade de explicar tais fatos considerando-se "algo mais", não expresso até então. É nessa explicação que a Naturph...
