The most recent bonus for restoring building façades, for instance?
“In recent years, we have tried to link ecobonuses and energy efficiency works to real benefits for communities, and at the same time resist pressure from lobbies. This happened when, for example, we reduced incentives for awnings and raised incentives for external thermal insulation buildings, which have a much more significant result in terms of cost-benefit ratio”.
So not an easy move in a country that has made numerous mistakes, like the ill-conceived mega incentives on solar panels, which focused all its attention on the quantity rather than the quality of the works.
“Exactly, which is why all the speculative funds have come to invest in Italy because we have guaranteed the highest incentives in the world for renewables. It’s certainly true that we had to take back some ground, but if we had scaled the incentives better, we could have benefited from the effect of the experience gained over time. If we had spread them across ten years rather than five, for instance, we would now have more updated and better performing generation facilities. We must not make the same mistakes”.
Where, for example?
“Well, recharging infrastructure for electric mobility. Because the somewhat superficial model that has started to establish itself is to install recharging stations at 100-meter intervals, which mayors love to boast about. A choice that involves massive investment in distribution networks. So these are investments which, as should be the case, affect bills for households and businesses, bills which, in Italy’s, case are already some of the highest in Europe, with a price for energy services which is just barely 36% of what consumers pay”.
And the allure of electric cars, which are direct elements of a massive parcelled system balance when recharging at the stations, most of all at home?
“A scenario which should by no means be excluded in the future, but which should be developed gradually and carefully, for the same reasons I mentioned earlier”.
Slowing down on recharging infrastructure?
“Not at all, quite the opposite. There is another, maybe even complementary model, using the existing network of filling stations, which itself needs to be upgraded. Why not refill electricity too, and maybe predominately at old filling stations converted or integrated with the recharging infrastructure? With, for instance, stationary 30-megawatt batteries powered at medium voltage, to be installed in the place of old service stations, as infrastructure that balances energy production and consumption in the area and has the added advantage of shortening the charging time for electric vehicles due to the power available. Which is all based on a picture that complements the stations, which can have benefits like car parks for company employees, where the cars remain stationary for a predictable period of time, but stay off the roadsides”.
It seems obvious that the race towards an electricity system with really extensive infrastructure could be worth the risk of some minor operating errors. Is that the case?
“Be wary of the makeshift all-electric fast ride. It does makes sense for us to generate all our electricity from renewables. But we have to take care here over the effect this could have on electricity distribution grid networks. Most houses today have a 3-kilowatt supply, with an average of 9 kW per floor. If you switch everything back to electricity, including the heating, the power required would increase fourfold: 40 kW per floor. A significant increase, which would entail replacement of all electrical wiring, both inside and outside the building. An operation that does need to be done, but in a gradual manner with tried and tested technologies. Networks have to grow, modernise, develop, improve security, without coming under undue stress. Not to mention the requirement to compensate the investments of companies that meanwhile have brought gas to all the houses, which in the case of sudden decommissioning should somehow be compensated through the bills”.
