Designers, installers, certifiers, maintainers, manufacturers and retailers ... from the market of**energy efficiency** good job prospects arrive for everyone because in fact there is so much to do. If all the best solutions were adopted for**energy efficiency** in Italy, energy consumption would theoretically drop by 297 TWh per year from now to 2020 (44 electric TWh and 253 thermal TWh).

But one thing is theory and another is practice, one thing is the optimal and another is the probable. So let's do all the flaws of the case and arrive at a forecast that takes into account all possible brakes and obstacles (uncertain regulatory framework and lack of culture above all) to imagine a scenario of penetration of solutions for the**energy efficiency** which from 'theoretical' becomes 'expected', that is, it is believed that it can be achieved in reality.

Well, according to the scenario probably 'expected' the goal of **energy saving** which is believed to be achieved in Italy between now and 2020 is about 96 TWh, ie only one third of the 'theoretical' savings but in any case a considerable value. In detail, the 'expected' situation envisages: 21 TWh of electricity savings (6% of consumption recorded in 2011) and 75 TWh of thermal savings (11% of 2011 consumption). The analysis with relative numbers is obviously not ours but of the Politecnico di Milano (Energy Efficiency Report) which presented it in November 2013.

What's the good news? Apart from realizing that 'it can be done', from the above numbers it is possible to calculate that the achievement of the 'expected' potential market of interventions for**energy efficiency** would give rise to an average annual turnover between now and 2020 estimated at over 7 billion euros. Of these, approximately 2 billion euros refer to interventions for the efficiency of electricity consumption and the remainder to interventions for the efficiency of thermal consumption.

According to the engineers of the Politecnico di Milano, the residential sector represents the area associated with the greatest 'expected' potential for **energy efficiency** (58% of the total turnover), followed by the industrial sector with a potential of 2.4 billion euros, equal to 33% of the global potential. It is difficult to estimate the savings in terms of CO₂ emissions and the real employment impact of the solutions for**energy efficiency** in terms of jobs (the Report does not contain these data) but that this is an extraordinary economic driving force is completely evident.
