Energy assessment of a wave energy converter in a small island. A case study
The diffusion of technologies supplied by Renewable Energy Sources (RES) is contributing to the challenge of reduction of energy dependence from fossil fuels, avoiding the emission of several polluting substances and greenhouse gases (GHG). Already today, global warming caused by human activity is estimated at around 1∘C; energy consumption attributable to human habits is no longer sustainable. To date, energy production is still heavily dependent on fossil fuels. To reverse the negative trend, it is necessary to invest in new technologies and improve the efficiency of energy production plants in general. In particular, a wave energy converter will be presented, consisting of a buoy connect…
FEM Analysis: A Review of the Most Common Thermal Bridges and Their Mitigation
The necessity to improve the energy saving potential of buildings is now a duty. European and national policies are being implemented to address the important decisions being made on this subject. For these reasons, several studies focus on this relevant topic. This paper review not only focusses on it but studies it in-depth. A commercial 3D simulation software was used to design a building sited in Palermo estimating the thermal losses before and after external envelope insulation. In particular, all the thermal bridges (TBs) were analysed with the finite element method (FEM) and mitigated with rock wool insulation. The paper shows the linear thermal transmittance difference and heat flux…
State of art and economic evaluation of wave energy converters. A case study
The even increasing energy demand in the world is a relevant problem for the modern society. The energy supply from fossil fuels has become a critical aspect due to the progressive reduction of reserves and political instability among the Countries. For these reasons, the exploitation of renewable energy sources is looked with a great interest. In this context, solar, wind, geothermal, hydropower, and biomass can be successfully used through commercial technologies. Other potential renewable energy sources could have potential applications in the next future. Among these, sea wave is considered a very promising energy source, especially for small islands. In this context, the paper propones…
