The continuous growth of the population worldwide, especially in urban areas, has caused a significant increase in energy consumption, which is saturating the regeneration capacity of natural ecosystems, both to produce resources and to assimilate waste They are generated. This situation is causing serious damage to human health and the environment due to air pollution and the risks generated by the inadequate transfer and confinement of hazardous waste, in addition to the high social and economic costs derived from this situation.

In this context, and within the framework of its social responsibility, the Autonomous University of Nuevo León established for several years a policy of efficient use of energy, in order to promote the culture of proper use of this resource, with the aim of changing inadequate energy consumption habits carried out by some members of the university community, which has allowed significant energy and economic savings to be achieved, as well as reducing greenhouse gas (GHG) emissions derived from the daily activities that UANL carries out to fulfill its academic goals

Among the activities currently promoted among members of the university community, it is to provide guidance and technical support to save energy in institutional buildings, both academic and administrative, carrying out some changes that become imperceptible for the most part of users, but with which significant energy savings are obtained. An example of this situation is the adjustment of the temperature of the air conditioning systems in classrooms and offices that is 24 ° C in the summer and 20 ° C in winter.


Regarding the use of artificial lights in university facilities, the use of natural light in classrooms and offices is promoted thanks to the architectural designs with which the new buildings are built, in addition to the fact that the lights must remain off and computer equipment must be completely shut down when they are not being used or at the end of the working day.

On the other hand, it is recommended to configure the screensaver / black mode or delete it; use laptops because they are more efficient, use LCD screens and activate the energy saving system of computer systems.

In order to show the savings in energy consumption that result from the change in habits that members of the university community carry out, the UANL publishes semiannually the evolution graphs of electricity consumption, which allows users to verify the results derived from their participation.

Additionally, the Ministry of Sustainability issued five technical guidelines to promote the efficient use of energy, which support, guide and evaluate the policies and recommendations that are applied in each of the university units, among which the “Technical guidelines for testing products aimed at improving the energy efficiency of air conditioning equipment” and the “Technical guidelines for the equipment of luminaires for classrooms”, which have directly influenced the decrease in the consumption of electrical energy, since the 75% of energy consumption is attributable to these types of equipment.

During 2018, there was a decrease in energy consumption from 98.14 million kWh in 2017 to 95.3 million kWh, mainly due to the changes of luminaires and conventional air conditioning equipment for high energy efficiency equipment and changes that have been made in the design of real estate, which has allowed the use of solar energy as a source of light during the day and the decrease in the consumption of this important resource by users.

In the case of per capita energy consumption, it went from 499 kWh / person-year in 2017 to 494 kWh / person in 2018, due to the decrease that was recorded in energy consumption and the fact that in 2018 the Total university population (students, professors and administrative staff) to calculate this value, unlike the past where only the student population was considered.

31.5% of all the electrical energy that was used by UANL in 2018, was generated through clean sources.

Increasing social and institutional awareness of the need to use renewable energy as an effective method to address the serious effects of climate change, in addition to ensuring economic and social development, from sources of durable energy and compatible with the environment.

Renewable energies are the alternative of the future, they are clean, environmentally friendly energies that reduce risks to human health, so it is essential to incorporate these types of alternative technologies in all areas of social and productive work, including Institutions of Higher Education.

Due to this situation, the UANL is in a process of initial implementation of the use of renewable energy, despite the volume of investment that this action entails due to the size of its facilities since it is a macro University where they study daily and more than 200,000 people work, and additionally have against the long return time that this type of economic investment requires. Despite these obstacles, different university departments have implemented systems for generating electricity and heat, using photovoltaic panels and wind turbines.

Additionally, the UANL currently carries out administrative and legal consultations to be able to supply energy generated by renewable methods at a lower cost and with enormous environmental benefits.

Programa de fomento al uso de fuentes de energía renovable

Within the program to promote the use of renewable energy sources, the Autonomous University of Nuevo León made an investment of $ 14,000,000.00 (MXN) to install 1,502 photovoltaic panels on the Mederos Campus, with a generation capacity of 813,000 kWh per year, which are used to meet the electricity needs of the Faculties of Economics, Visual Arts and Performing Arts, as well as the Center for Research, Innovation and Development of the Arts, benefiting more than 3,455 people.
