The energy transition marks the passage from the use of non-renewable energy sources to renewable sources using alternative energies, the adoption of energy saving and sustainable development techniques. After the United Nations Conference on Climate Change in Glasgow, has emerged the need to move quickly towards a change in the socio-economic system to avoid severe climatic consequences.

Currently, have been used energy deposits such as coal, oil, anthracite and the like. Now, however, we want to use solar flows, molecules, wind, photons, osmosis, sea currents, or alternative solutions.

In this transition phase, it is important to remember that these flows are not always programmable and reliable. For this reason, it is necessary to use also energy reservoirs in order to stabilize the non-programmability of these flows. The use of alternative and ecological sources of energy represents a double opportunity: for economic development and for the environment. In the context of the development of renewable sources and economic development, South Italy has an opportunity for global affirmation.
