Energy conservation - The transition
For the past several years, all the debates and analyses related to the use of primary energies are influenced by a set of incontrovertible facts. They all lead to the same conclusion: "it is essential to rationalize the use of energy on a world-wide scale, in order to ensure the sustainable future of the species that inhabit the planet and of the corresponding biodiversity that supports them".
A transition to a sustainable energy system is necessary, also from “the economic point of view”, that guarantees the maintenance of our generation's and future generations' welfare, from a perspective of respecting the environment.
This transition requires significant effort in research, development and technological innovation, as well as greater social awareness of the energy problem. In the short and medium term, the objectives for implementing a sustainable energy system would include the application of measures such as:
• Encouraging energy saving and efficiency.
• Promoting renewable energy sources.
• The development of the necessary energy infrastructures to face the increase in consumption during this period of transition (gas-based infrastructures).
