Currently it is possible that in a substantial and important way to be small basic energy consumption in the sectors mentioned above, without affecting the quality of services, and even improve them in some cases, if necessary correct, logical and firm policies are applied. This influences also and favourably in terms of the impact produced in the environment, including therefore relates to the, as currently discussed, problem of global warming. There is already at this time, many countries that, due to high consumption summed with a limited energy production, are forced to resort to the importation of a good part of the energy they consume.

If it is true, as we have seen, that significantly using new technologies available from several years ago, it would be possible to reduce the power consumption up to a ratio of 55 percent, according to the estimate by the electric power Research Institute, the United States for already quite some time (Dept of energy of the USA. Annual Energy Review 1991), and which has proved to logic as a path to follow. You have an important example in relative technology to the energy applied in lighting, which in recent years has undergone an enormous evolution, what we can note up in the evolution that has been in common light bulbs used until a few years ago and those who currently have invaded already, almost in its entirety, the illumination of private homes. We can also note the breakthrough had on public and commercial lighting, even and when the latter is of note that the simple function of light, to reach a stage of combination advertising, much of which is no longer only nocturnal, with large illuminated signs and any variant of informativo-comerciales presentations currently in use has exceeded. There is no doubt that there is a big change since the time of the incorporation of the light referred to in common parlance as fluorocente or also called in his time cold light, which at the time was considered as a big jump in the lives of some of the communities on the planet.
There has also been enormous advances in insulation, such as the Windows systems, every day improved, which allow the passage of light, but preserving the passage of cold and heat. The new air conditioning and refrigeration systems that added to the previous ones and other insulation applications, have managed to bring down energy consumption in up to 90%, with respect to the equipment used some years ago. There is no doubt that this is an important and interesting subject, but by this time they will stay, struggling to leave issues such as those relating to the energy/transport relation, the different sources of energy available, either come to analyze the eternal discussion between the advantages and disadvantages of nuclear energy.
