Offshore wind energy in Sicily – Offshore wind energy is one of the most promising and innovative technologies to address the global energy transition. Climate change, air pollution and the growing need for sustainable energy production are pushing the world to look for alternatives to fossil fuels. Among the options, offshore wind energy is emerging as one of the most efficient and cleanest. With its unique geographical location, vast marine resources and constant wind currents, offshore wind represents an unprecedented opportunity for renewable energy production and carbon emission reduction.
Global overview of offshore wind
In the global context, offshore wind has seen exponential growth in recent years. This increase is largely due to government incentives, technological advances and growing awareness of climate issues. Countries such as the UK, Denmark, Germany and China are investing heavily in the development of offshore wind farms, with installations supplying energy to millions of homes.
In 2020, global offshore wind power capacity exceeded 35 gigawatts (GW), with a forecast to reach 234 GW by 2030. This increase reflects the growing importance of offshore wind energy as a key source of electricity generation. Europe is currently the undisputed leader in the sector, with the UK hosting the world’s largest offshore wind farm, Hornsea Project One, located off the coast of Yorkshire. But other continents are also catching up: the United States and China have a number of large-scale projects in the pipeline.
Offshore wind power in Italy
In Italy, wind energy has historically played an important role, mainly with onshore installations. However, offshore wind is gaining in importance, thanks to regulations promoting renewable energy and government incentives. The National Energy Strategy (SEN) has set ambitious targets to reduce CO₂ emissions and increase the share of energy produced from renewable sources, and offshore wind is seen as a crucial element in achieving these targets.
In Sicily, there is huge potential for the development of offshore wind farms, thanks to its coastline exposed to strong and constant sea winds. The region is already attracting the attention of national and international investors interested in developing clean energy projects. However, as with many infrastructure projects, there are bureaucratic and legislative challenges that need to be addressed to facilitate a rapid development of the sector.
Current projects and future prospects for Sicily
Currently, Sicily has seen the approval of a number of pilot projects for offshore wind energy. These projects aim to test the feasibility of the technology in the Mediterranean Sea and to better understand local specificities, such as the management of the marine ecosystem and the interaction with other economic activities in coastal areas, such as fishing and tourism.
A significant example is Renexia’s project to build an offshore wind farm off the coast of Sicily, with an estimated capacity of 2.9 GW. This park would be one of the largest in Europe and would contribute significantly to the Sicilian energy mix, reducing dependence on fossil fuels and bringing economic benefits in the form of new jobs and infrastructure investments.
Comparison between offshore and onshore wind power
A crucial element to consider when analysing offshore wind power is the comparison with onshore wind power, i.e. plants located on land. While both types of plant use wind to produce electricity, offshore wind has several distinctive advantages that make it an increasingly attractive choice.
Firstly, offshore wind farms are generally more efficient than onshore wind farms. This is due to the higher speed and consistency of offshore winds. Offshore turbines can be located far from the coast, where winds are not impeded by buildings or natural relief, allowing for more stable energy production. In addition, the absence of space constraints allows larger turbines to be installed than onshore turbines, further increasing production capacity.
Another advantage of offshore wind power concerns visual and acoustic impact. While onshore turbines can often generate controversy due to noise and impact on the landscape, offshore turbines are located far from inhabited areas, minimising local concerns.
From an economic perspective, offshore wind has higher installation costs than onshore wind, mainly due to the complexity of the infrastructure needed to install turbines at sea. However, these initial costs are partly offset by the long-term efficiency of offshore plants and the constant production capacity they can guarantee.
Environmental and social benefits for Sicily
In addition to the obvious economic and energy benefits, offshore wind energy also offers a number of environmental and social benefits that can have a positive impact on Sicily. The reduction of greenhouse gas emissions is one of the main benefits of this technology. Every megawatt produced by offshore turbines avoids the use of fossil fuels, reducing air pollution and contributing to the fight against climate change.
Environmentally, the impact of offshore wind energy on the marine ecosystem is generally lower than other forms of industrial development, such as drilling for oil and gas. Advanced technologies are employed to minimise interference with marine fauna, and many of the areas where wind farms are installed are areas with little human presence, minimising direct impact.
Another important social aspect is related to job creation. Offshore wind development in Sicily could help stimulate the local economy, creating new employment opportunities in sectors such as engineering, construction, maintenance and plant management. This is particularly relevant for a region that has historically suffered from high unemployment rates.
Public-private partnerships and the role of institutions
The success of offshore wind development in Sicily will also depend on the ability to create solid partnerships between the public and private sectors. The regional and national governments will have to work closely with investors and companies to create a favourable environment for the installation of these plants.
At the regulatory level, it will be crucial to simplify bureaucratic procedures and speed up authorisation processes, which are often one of the main obstacles to the development of energy infrastructure in Italy. At the same time, institutions will have to ensure that projects meet strict environmental standards, ensuring that offshore wind energy development takes place in a sustainable manner.
Educational and research institutions will play a crucial role in training a specialised workforce and promoting technological innovation. Sicilian universities and research centres could become strategic partners in developing innovative solutions to improve turbine efficiency and reduce the environmental impact of offshore installations.
Future challenges and opportunities
Despite the great potential, there are some challenges that Sicily will have to face in order to fully develop offshore wind energy. One of the main difficulties concerns the high initial costs, which may discourage some investors. However, with adequate public policies and financial incentives, these barriers could be overcome.
Moreover, a balance will have to be struck between energy development and the protection of natural resources and traditional economic activities, such as fishing. Collaboration between different actors in the area will be essential to ensure that offshore wind energy is harmoniously integrated with other activities.
Ultimately, offshore wind energy represents an extraordinary opportunity for Sicily, not only to reduce dependence on fossil fuels and improve energy security, but also to stimulate the local economy and contribute to the global fight against climate change. If exploited correctly, offshore wind power could turn Sicily into a model of sustainability and innovation in the Mediterranean.

Through the regional call ‘Sicilia che Piace’, promoted by the Sicily Region’s Department for Productive Activities, In Rete SRL has developed the ‘Eolico Offshore Sicilia’ project, an articulated and innovative initiative that explores renewable energy, with a focus on offshore wind power in Sicily. This multidimensional project is structured to inform and raise awareness on the benefits of sustainable energy, through a multimedia approach integrating articles, documentaries, and online platforms.
