An Analysis of the Geothermal Energy of Surface Water in Fátima do Sul, Mato Grosso do Sul, Brazil with an Emphasis on the Climatization of Buildings Environments

Abstract

Investment in unrenewable energy sources has grown at a rapid pace during the beginning of the 21st century, and they may be exhausted by the middle of this century if this rhythm of consumption is maintained. Sustainable solutions have become a priority and the use of Geothermal Energy from Surface Water has attracted interest as a source of clean and renewable energy which can be used to climatize constructed environments. This article analyzes the surface water of a reservoir located in Fátima do Sul, Mato Grosso do Sul determining its temperature at depths of 0.3 to 1.5 meters (1 to 5 feet) using our own method which employs an Arduino Mega 2560 R3, a free electronic hardware prototype with a single board. The results demonstrate an inverse relationship between the variation in the water’s temperature and an increase in depth, or in other words, there are smaller variations in temperature at greater depths. This fact gives these waters the capacity to store heat, and thus it can be employed in heating and cooling constructed environments.
