Much has been discussed about the energy future of the towns, cities and countries and many have been the arguments that have been exposed. So much has been written and said about the merits and risks of nuclear energy application, for example, for non-military, and ordinary citizens that we are somewhat confused. Really the application of nuclear energy could lead to a safe and reliable future, or is both the risk of its use in non-military applications, which leads to a tragic future and possibly uncontrollable, to escape from our hands?. We must not forget that the energy used by different countries, is applied in very different ways, but however, trying to simplify the problem, we consider that in today’s cities, there are three major activities in which you use the large Most of the energy, apart from the war effort and space exploration: residential and commercial activity, industrial activity and related activity transport.
In countries such as the United States, according to some published statistics, the first activity mentioned (residential and commercial) consume on average slightly less than 36% of the total activity related to industrial processes consume approximately the same (37% ) and if the transport activities attributed to them the balance, consume on the order of 27%. Even when the distribution is considered from a viewpoint somewhat simplified general, we achieved to provide a clear idea of the importance of the three basic aspects considered here. Even now as some theories hold that energy consumption increases in direct proportion to the growth of the economy, we can say that you are ignoring the importance of consumption have policies, when properly applied, related to energy savings and it is also rapid evolution of technology when applied timely and appropriately.
