Abstract
This paper reviews the processes to produce energy nowadays as well as the environmental problems that each of them present. The possible solutions as well as the research lines developed to solve these problems are resumed. A possible energetic future is described, although the different strategies chosen by the different countries could differ. This will give place to disequilibria that will lead to industrial and economic problems in those countries whose strategies greatly differ from those of the rest of the countries.
