“…Climate change, the Kyoto Protocol, and the need to reduce energy costs are obliging industries to rapidly acquire knowledge of energy options in key sectors [1], such as the agri-food sector. For example, photovoltaic (PV) energy is one of the renewable energy sources that is widely used in the agricultural sector for various activities [2,3], such as water pumping systems for irrigation, or electricity generation [4][5][6]. Nevertheless, to date, it has not been widely used in wine production.…”

This research developed a system that can make factories more independent from the grid. The system enhances efficiency since factory operation is powered by the renewable energy generated during the production process. Winemaking is a key sector that can profit from such a system because wineries can recycle much of the waste from the raw materials employed in wine production. Moreover, the solar energy collected at winemaking facilities can also be used to reduce electricity consumption and thus increase energy efficiency. This study investigated the feasibility of using renewable energy sources, such as solar energy, in wineries in Spain, given the quantity of renewable energy produced in the country. For this purpose, cost-effectiveness, power generation, CO 2 emissions and the renewable energy fraction were taken into account. The assumption was that the photovoltaic system was grid-connected. Research results showed a reduction in electrical power costs ranging from 4% to 36%. This reduction was accompanied by an increase in the use of renewable energy of up to 57%. The results obtained are based on self-consumption or net metering policy as well as the production capacity of the winery.

Industrial Photovoltaic Systems: An Economic Analysis in Non-Subsidized Electricity Markets

Photovoltaic (PV) systems are becoming a relevant electricity source, characterised by a growing trend in the last years. This paper analyses the economic feasibility of investments in industrial PV systems of different sizes (200 kW, 400 kW, 1 MW, and 5 MW), in the absence of subsidies, and in a mature market (Italy). The selected indicators for this kind of assessment are net present value (NPV) and discounted payback time (DPBT). Furthermore, the environmental advantage in comparison to fossil sources of energy is evaluated through the reduction of carbon dioxide emissions (ER cd ). Finally, a sensitivity analysis on critical variables (percentage of self-consumed energy, average annual insolation rate, annual electricity purchase price, annual electricity sale price, unitary investment cost and opportunity cost) is conducted. Results highlight the strategic role of self-consumption in a market characterised by an absence of public policy incentives and the presence of interesting economic opportunities for industrial applications.

“…In 2002, Society of Environmental Toxicology and Chemistry (SETAC) issued a Code of Practice to define the objectives of the LCC methodology (Rebitzer and Seuring, 2003). LCC is relevant given that the ABC methodology does not discount values in the assessment and does not consider the long-term cost analysis that is of fundamental importance in a capital intensive sector, such as agri-food (Tudisca et al, 2013;Sarno and Barmo, 2014); the method is also important about net financial position repayment analysis and even for evaluation of environmental aspects of investment (Notarnicola et al, 2004;Troiano and Marangon, 2010;Lopolito et al, 2011;De Gennaro et al, 2012;Di Trapani et al, 2014;Sgroi et al, 2014;Bonazzi and Iotti, 2014). LCC takes into account all costs, discounted year by year for the entire life of the project, thus long-run cost analysis is frequently applied according to the LCC approach (Schiffauerova and Dale, 2006;Kallunki and Silvola, 2008;Korpi and Ala-Risku, 2008;Srivastava, 2008;Hedeşiu et al, 2012).…”

Investing in the main home is an important form of investment for families and represented one of the main family assets in Italy in the second half of the 20th century. The evaluation of the convenience of the house purchase needs to consider that technologies in construction have undergone a rapid change in recent times that proposes an approach to sustainable building technologies, such as dry construction systems that can reduce energy consumption over time. Moreover, these construction systems are encouraged with tax deductions from the state, that is, financing with public spending via a tax benefit, which recognizes the role of externalities of investments in sustainable construction. The article would apply Life Cycle Flow (LCF) model to a residential building; LCF is based on the Life Cycle Cost (LCC) model and adapted to assess a real estate investment, such as a residential building for private use, taking into account the effects of a tax benefit. The model quantifies the cost of satisfying consumers' housing needs in the long run. The model takes into account the absorption of financial resources at all stages of property investment. The proposed LCF approach quantifies an average discounted cash outflow per year and an average discounted cash outflow per year per surface unit in square meters; thus, it is possible to compare project alternatives and choose the alternative that minimizes the absorption of financial resources in the long run. In this article, the LCF model is applied to three project alternatives and highlights the energy savings in the long run for consumption choices and the importance of tax benefits for the reduction of the cash outflow for a family in long-term housing. Given the results of the research, the proposed LCF model can be applied on a larger scale, in particular, to quantify social welfare generated by tax benefits financed with public spending, in terms of economic activation and assessing environmental externalities.
