Smart Cities are those cities that benefit from technology to improve the quality of life of their inhabitants, taking into account the principles of energy efficiency and sustainability . Its objective is none other than to achieve greater efficiency in the management of resources.
It is estimated that by the year 2050, 85% of the world population will live in cities. What, according to the UN, can cause a serious problem if a balance between social and environmental aspects is not established. Estimates indicate that 75% of the world’s energy is consumed in cities, which in turn generate 80% of greenhouse gases.
Smart Cities would take advantage of the potential of technological advances to save costs , offer new economic and social services, reduce environmental impact and promote innovation . In addition, in these technological cities, both citizen participation and the participation of Public Administrations are fundamental for the achievement of the objectives that this type of cities pose.
What aspects make up a Smart City?
The use of photovoltaic panels , electric vehicles , the installation of windmills in the lampposts or the promotion of the use of bicycles , may be the most popular aspects when talking about Smart Cities. However, these also include other aspects:
– Development of technological infrastructures that include information networks as a form of communication.
– Use of renewable energies , and use of them to reduce costs and emissions of polluting gases.
– Use of resources in accordance with principles of sustainability and cooperation .
– Development of service models that combine public and private elements .
– Development of sustainable governments that promote data accessibility and transparency.
Some examples of Smart Cities
Now that we know what the Smart Cities are, we are going to know some of the most important Smart Cities that currently exist. They are the following:
- Copenhagen : Considered one of the best cities to live in, Copenhagen stands out as an example of an intelligent city for its management of water , the use of wind energy and the promotion of green means of transport that contribute to the reduction of CO2 emissions.
- Melbourne : In Melbourne they have developed the 1200 Buildings Project , with the aim of reducing the emissions of polluting gases in 1200 buildings, mostly factories. The objective of this Smart City is none other than to reduce emissions to 0 by 2020.
- Málaga : The sunny city of Málaga has decided to focus its efforts towards energy management. To achieve energy control , automation and communication technologies that favor energy management have been installed in different parts of the city, for example, through the installation of tele-meters through which it is possible to know the energy consumption at real time and thus be able to decide whether to disconnect from the network to consume self-generated energy.
