The exploitation of renewable sources in the heart of the city with low costs is the new approach to perceiving the world as a network of small villages.  For the small island communities that obtain energy from expensive diesel generators, the application of innovative WECs integrated into breakwaters is certainly the most reasonable (between the renewable energy technology) in order to substitute the energetic resource. In order to obtain a controlled output of energy, it can be chosen to produce, when necessary, electrical or hydrogenous current, to use for the same electrical production during the periods of calm sea or to produce drinking water by osmotic treatment.  The production of drinking water has very important ethical aspects, mostly if it is applied in some coastal region of African or Asian countries, where the full access of the services of drinking water is still partially compromised.  In specific terms, the port infrastructures connected with the onshore oil and gas installations can be integrated with the DIMEMO device as environmental mitigation and compensation interventions. The DIMEMO, included in the integrated project on the touristic and commercial aspect of the port, resolves critical matters concerning the environmental impacts from the use of other technologies which exploit renewable energy source. Although they provide benefits from the absence of CO2 emission, technologies as photovoltaic, hydroelectric and wind energy are, mainly recently, being often strongly contested from the environmental organizations, which express perplexity regarding the visual and acoustic impact on the environment and the fauna.
The DIMEMO has minimal environmental impact because:

  • It is not visible, as it’s embedded in the crown wall: rather, the frontal reservoir, as a sort of small stilling basin, leads a lower crest of the crown wall, reducing the effects of the emerged structures on the urban skyline;
  • It is silent: the electro-mechanic apparatus is well enclosed in a specific machinery space;
  • It is harmless to the marine fauna: it does not interfere with the marine fauna because the frontal ramp is located above the sea level. Instead, it contributes to improving the quality of the water in the internal area of the harbour, mitigating the rate of the pollutants in the sea.
  • It allows reducing the “environmental costs” of construction by avoiding the use of a large amount of blocks for the armour layer, and thus reducing the quantity of stone in the core. In this way, an important positive impact can be noted on the environment because the extraction from natural quarries and the transport in situ of these materials is not required.
