To talk of research into energy today is to discuss an extremely vast range of activities, with characteristics involving a great many different subjects. It must be admitted that the correct, rational use of energy sources requires, first and foremost, the study of classic subjects in relation to combustion processes, thermodynamic cycles, electrical generation, transmission and distribution systems and the use of nuclear energy. Secondly, we then need to study innovative materials, efficient automation and measurement systems, devices and systems that are able to use non-conventional forms of energy (wind power, solar power), in addition to all those aspects focussing on protecting the environment and limiting the damage that inevitably accompanies any energy conversion process.
