According to the United Nations, more than 55% of the world’s population lives in cities. And it is estimated that this proportion will increase to 68% by 2050. This growth raises the alarm in terms of resource management and the sustainability of cities.
So, what is a Smart City?
A Smart City is a city that uses Information and Communication Technologies (ICT) to improve the quality of life of its inhabitants. These technologies enable real-time data collection, analysis of information, and data-driven decision-making to improve the sustainability of the city and manage it intelligently.
What are the characteristics of a Smart City?
Smart Cities apply innovative technologies and solutions in different areas of urban life:
What role do renewable energies play in Smart Cities?
Renewable energies make it possible to generate clean, sustainable and decentralised energy.
Solar Energy
Solar energy is one of the most widely used renewable energy sources in Smart Cities. Installing hybrid solar panels on buildings and public areas generates clean energy that reduces dependence on fossil fuels. Smart solar energy management systems are also used to improve energy production and consumption.

Wind Energy
Wind energy is another important source of renewable energy in Smart Cities. Wind turbines in urban and rural areas harness the wind and generate electricity. In addition, these turbines are integrated into the city’s infrastructure and are intelligently managed to maximize energy production.
Hydroelectric Power
In some Smart Cities, hydroelectric power generation systems are also used to take advantage of the flow of water in rivers and canals. These systems use hydroelectric turbines to convert the kinetic energy of water into electricity.
Energy Storage
They are very useful when demand increases or when renewable energy sources are not available.
What examples of Smart Cities do we have in Spain?
In Spain, Barcelona is an example of Smart City.
In 2015 it took the title of the smartest city, and since 2012 it has been trying to apply new technologies that improve the quality of its citizens’ life.
Some examples are the use of advanced technology for waste management, public transport, lighting, or parking, among others.
