Energy efficiency is to intelligently use energy to reduce energy consumption, but without reducing our quality of life, we could save energy without being efficient, although efficiency consists of being able to carry out our daily activities with the best practices. It may seem complicated, but we realize that using energy better is easier that it seems.

Every day we consume tons of energy since we began our day until when we sleep, the industry, companies, means of transport, all consume energy in their processes, even the human being.

The word energy comes from the greek energeia and means force in action, it is the capacity of the bodies to carry out a work and that allows them the movement or displacement, as well as changing their properties. Energy is not destroyed, it only transforms, like the resources that are used to produce energy or electricity and the way in which it dissipates or transforms form one state to another such as cold, heat, movement, even the energy of the human being is obtained from the food is ingested.

There are renewable energies such as hydro, solar, tidal, geothermal, wind and biomass in which their processes of transformation into useful energy are not consumed or depleted as. On the other hand, there are also non-renewable energies such as oil and its derivatives, coal and natural gas in which its processes of transformation and use of useful energy are consumed and depleted. Energy results in one of the great measures of social welfare that every nation seeks, which leads to a great demand for energy on a global scale and that, depending on the process used to obtain it, greenhouse gas emissions are produced, dioxide carbon (CO2), among other waste that affect the climate and the environment.

Energy efficiency seeks to reduce the dependence of other countries on external energy sources, which translates into strategies to reduce energy consumption, reduce pressure on natural resources to produce energy whose benefit is lower gas emissions and better care for the climate and environment.


The most common practices begin with oneself, at home, at school, at work and can be implemented at no cost, we just have to look around and pay attention to apply these practices:

  • Appliances consume between 50% or more of electric billing, the refrigerator is the maximum consumer and therefore we must open the door as little as possible, avoid placing hot food inside as this makes the usual cool food, which results in a greater amount of energy to work.
  • Check your refrigerator’s seals, they probably leak and make your refrigerator work harder, you would have to change the seals if necessary.
  • Keep a distance between the wall and the refrigerator of approximately 15 centimeters for the heat to flow.
  • Maintains the refrigerator, cleans inside and dust that accumulates between the compressor and the condenser grids.
  • Cook with the pot covered, foods cook faster and use less gas.
  • Disconnect all the devices that you are not using, the devices in standby mode consume energy even when they are not used but remain connected.
  • Turn off the boiler or heater that is not in use, the pilot flame consumes gas permanently.
  • Wash clothes with cold water and full load.
  • Iron minimum and in the morning.
  • Use more efficient bulbs that illuminate the same as the traditional ones and consume less energy.
  • Keep the heat in your home by closing doors and windows.
  • Use natural light as possible to illuminate.
  • Turn off incandescent lamps that remain lit at night and turn on the saving lamps.
