The impact of the electricity tariff reform on renewable energies and energy efficiency investments: The case of the Italian residential market

This article investigates the impact that the electricity tariff reform is likely to have on investments in renewable energies (i.e., photovoltaics) and the adoption of energy efficiency measures (i.e., installation of heat pumps and efficient home appliances) in the residential market in Italy. The study develops detailed cost comparisons and simulations considering two different investment scenarios (before and after the reform) to conclude that the reform will: (i) have a negative impact on investments in photovoltaic systems; (ii) favor the adoption of energy efficiency measures, such as efficient home appliances

The environmental impact of electric vehicles: A novel life cycle-based evaluation framework and its applications to multi-country scenarios

Electric mobility is being studied as a possible solution for reducing the environmental impact associated to the transportation sector. However, there is a huge ongoing debate among scholars and practitioners on the extent to which Electric Vehicles perform better in terms of greenhouse gases emissions against Internal Combustion Engine Vehicles, and especially on the variables that affect such performance. To the best of our knowledge, most of the studies addressing the topic mainly focus only on some specific phases of a vehicle's life cycle, such as vehicle manufacturing and use, while comprehensive evaluations of the greenhouse gases emissions during a vehicle's life cycle are quite rare. Therefore, the paper aims to develop a comprehensive evaluation framework in order to estimate the environmental impact associated to Electric Vehicles and Internal Combustion Engine Vehicles, by adopting a Life Cycle Assessment approach. The evaluation framework is then adopted to estimate the environmental impact associated to Electric Vehicles and Internal Combustion Engine Vehicles in four different scenarios, each one assuming different countries in which the phases of a vehicle's life cycle take place. Results show that CO2 emissions over the Electric Vehicle's life cycle are lower than the ones associated to a comparable Internal Combustion Engine Vehicle in all the scenarios analysed. Moreover, the analysis highlights: (i) the huge impact on a vehicle's CO2 emissions associated to the geographical location in which the upstream phases of the vehicle supply chain take place (mainly for Electric Vehicles); (ii) the primary impact played by the use phase on the Electric Vehicles CO2 emissions, followed by the vehicle and battery manufacturing ones. Both evidences reinforce the impact of the energy mix on the environmental performance of Electric Vehicles, as further confirmed by the sensitivity analysis. The paper contributes to the extant literature by reaffirming the better environmental performance of Electric Vehicles compared to Internal Combustion Engine Vehicles in terms of CO2 emissions over the whole life cycle, also providing policymakers with useful suggestions for the promotion of Electric Vehicles as a means to tackle environmental issues

Factors affecting cost competitiveness of electric vehicles against alternative powertrains: A total cost of ownership-based assessment in the Italian market

Electric vehicles have faced a significant diffusion in the last years, however they still represent a minority share over passenger cars registrations worldwide. Economic factors play a crucial role in preventing a higher diffusion of electric vehicles, with particular reference to the higher purchase price compared to internal combustion engine vehicles. Indeed, potential electric vehicles buyers typically tend to underestimate long-term savings that can be achieved due to the lower operating costs characterizing electric vehicles compared to internal combustion engine vehicles (so-called "energy-efficiency paradox"). An emerging literature stream suggests that the availability of comprehensive economic comparisons between electric vehicles and internal combustion engine vehicles, based on the total cost of ownership, would increase the potential customers' willingness to buy an electric vehicle. However, there is an ongoing debate on the cost competitiveness of electric vehicles considering the whole ownership period, and in particular on the most influencing factors affecting it. The paper aims to fill this literature gap by assessing the cost competitiveness of electric vehicles against a broad set of alternative powertrains, with reference to the Italian market. To this aim, an ad hoc assessment tool based on the total cost of ownership has been developed, leveraging the extant knowledge on the topic and addressing current gaps. Results show that battery electric vehicles are characterized by the lowest total cost of ownership among analysed powertrains in two out of four vehicle segments evaluated, i.e., segments A (mini cars) and C (medium cars). This is mainly due to the presence of purchasing incentives and the lower fuel-related and non fuel-related operating costs characterizing battery electric vehicles compared to other powertrains, which more than offset the higher purchase price. In other cases, the relatively high purchase price characterizing battery electric vehicles (as well as plug-in hybrid electric vehicles) negatively affects their cost competitiveness. The study provides suggestions for managers of companies within the e-mobility value chain and policymakers on the levers to promote the spread of electric vehicles to achieve the decarbonisation targets for the transportation sector
