The islands are particularly vulnerable to the effects of climate change due to their limited capacity to manage and store resources. Furthermore, being surrounded by the sea, rising sea levels, exacerbated by global warming, represent an even greater challenge. In this context, many islands are looking for ways to increase its energy efficiency to mitigate environmental impacts and, in turn, adapt to new climatic conditions.
Tilos is a prominent example in this field. This small island in the Mediterranean Sea has become the first to be supplied solely with renewable energy, proving that an energy transition is possible even in limited territories. With a population of only 500 inhabitants, Tilos is also a Natural Park that is home to a rich biodiversity, being a temporary home to numerous species of migratory birds.
The Horizon 2020 project and Horizon Tilos
The change towards a renewable energy model in Tilos has been possible thanks to the Horizon 2020, the largest research and innovation programme in the European Union. Through the project "Tilos Skyline", 15 million euros were allocated to build infrastructures that would allow maximum use of energy solar and wind.
The energy situation of Tilos, like that of many other islands, previously depended on a submarine cable from the island of Kos, which supplied electricity via Fossil fuels. This connection was unstable and caused frequent power outages, affecting the economy and quality of life of the islanders. In addition, being a protected Natural Park, hunting is not allowed in Tilos, favouring the conservation of species, which further reinforces the community's commitment to sustainability. The Horizonte Tilos project has not only improved the island's energy stability, but has also shown how islands can become independent of fossil fuels and promote sustainable development.
Energy storage and self-sufficiency
One of the pillars of Tilos' success is its ability to store renewable energyThe Horizonte Tilos project includes the installation of an innovative sodium battery, which has a large storage capacity and is designed to be resistant to extreme weather conditions, which is essential on islands with such hot and exposed summers as Tilos. This system has also proven to be more economical compared to other storage solutions.
In addition to meeting local needs, the island has the capacity to sell surplus energy to Kos, which generates extra income for the community. This model not only ensures a clean and constant source of energy for Tilos, but also makes the island a role model for other island regions looking to improve their energy security and be economically viable.
Impact on local society and sustainability
El Horizon Tilos project It has not only benefited the island from an environmental aspect, but also social and economicWhat was once a community with severe energy constraints is now an internationally recognized example of how renewable energy can transform the lives of thousands of people.
In order to optimize energy consumption, they were installed smart meters which measure expenditure per inhabitant. These innovations not only contribute to energy efficiency, but also help to awareness of the local population about their own consumption habits.
In addition, reducing dependence on Fossil fuels has meant a significant decrease in the cost of energy. Previously, islanders paid up to 10 times more electricity due to the additional costs associated with transportation and distribution. This not only boosts the economic sustainability of the community, but also makes it more resilient to fluctuations in the fossil fuel market.
An example for other Mediterranean islands
The Tilos model has proven to be scalable and replicable on other Mediterranean islands, which face similar challenges. From installing solar and wind power, to battery storage and selling surplus energy, the success of this project has inspired islands such as La Graciosa y Corsica to follow the same path.
It is important to note that Tilos has not only addressed the energy challenge, but has also fostered the growth of new job opportunities within the renewable energy sector and in other sectors linked to sustainable tourism. With its successful model, the island is attracting both Tourists and investment, consolidating itself as a reference site for green tourism, which values sustainability and respect for the environment.
In addition, Tilos has been internationally recognized for its achievements in sustainability, receiving a prestigious Awarded in the RESponsible Island Prize competition, sponsored by the European Commission. This award recognises the island's efficiency in producing renewable energy for electricity, heating and transport. These successes have laid the foundation for Tilos to continue expanding its network of sustainable solutions, which now also include a small photovoltaic park y public electric charging stations for electric vehicles.
The future of Tilos is bright, and it is expected to continue moving towards a complete energy self-sufficiency in the coming years. With more renewable energy installations planned, this small Mediterranean island remains a beacon of inspiration for other regions of the world seeking innovative and sustainable solutions.
