Energy assessment of a wave energy converter in a small island. A case study

Abstract

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 connected by ropes to a mechanical motion converter with the aim to turn an electric generator.
