Urban efficiency begins with a new way of lighting our cities.

As every October 31, we celebrate World Cities Day, a date that, in our case, invites us to reflect on the important role that cities play in the fight against climate change and the construction of a more sustainable development model. Cities concentrate more than 65% of global energy consumption and generate a similar proportion of CO₂ emissions. And as the urban population continues to grow relentlessly, advancing solutions that make them increasingly efficient, resilient, and livable places becomes a global priority. At Edison Next, we are convinced that the transition towards more efficient cities begins, to a large extent, by rethinking something as everyday as the lighting of our streets. Light is a basic necessity, but also a powerful tool for sustainability. In many municipalities, public lighting represents more than 40% of total energy expenditure. Therefore, modernizing lighting systems through LED technology and intelligent control has become one of the most effective measures to reduce consumption, emissions, and municipal expenses. LED lighting not only allows energy savings of up to 70%, but also offers greater durability, lower maintenance, and superior lighting quality. But its true potential emerges when combined with remote management and intelligent sensor systems, capable of regulating light intensity based on the time of day, weather conditions, or street occupancy. Thanks to these solutions, cities not only illuminate more efficiently, but can also dynamically adapt to the real needs of their inhabitants. Sustainable lighting is the first step, but not the only one. At Edison Next, we understand energy efficiency as an integral strategy, where digitalization, renewable self-consumption, and advanced energy management systems (BMS) combine to create more sustainable urban environments. When these solutions work together, the results multiply. Efficient lighting projects thus become the starting point of an intelligent urban model, where data and automation allow optimizing everything from the climate control of a building to the charging of electric vehicles or distributed energy generation. Ultimately, it is about transforming consumption into knowledge and knowledge into sustainable action. In recent years, Edison Next has collaborated with numerous city councils across the country in the renovation of their lighting systems, with great success stories such as those of Lleida and Seville. Both projects have demonstrated that lighting is much more than a visual issue; it is a lever for urban transformation capable of generating immediate savings, improving citizen well-being, and reinforcing the environmental commitment of local administrations. World Cities Day reminds us that the urban future depends on making smart decisions today. That is why, at Edison Next, we will continue to work tirelessly so that every city, large or small, finds its path towards efficiency. Always betting on innovation, collaboration, and technological solutions that allow us to illuminate the present without compromising the future.
