“…Globally, buildings account for 33% of the total energy consumption, and this number increases to 90% in subtropical cities. − This high building energy consumption is partially due to the widespread application of traditional soda lime window glasses. These glasses have excellent visible-light transmission, but they also transmit near-infrared (NIR) light, the main heat source of sunlight .…”

Tungsten bronze is an effective near-infrared (NIR) shielding material for fabricating energy-saving smart windows. While high-performing NIR-shielding glasses can be fabricated by coating a tungsten bronze film on window glasses, these glasses suffer a short lifespan due to the adhesion and degeneration of film. In this work, we show that tungsten bronze-like material Na5W14O44 can be distributed in the bulk glass matrix during the facile melt-quenching glass fabrication process under an air atmosphere, overcoming the limitations of film-based glasses. X-ray diffraction, Raman spectroscopy, and X-ray photoelectron spectroscopy confirmed the presence of tungsten bronze-like Na5W14O44 functional units in the SiO2–B2O3–NaF glass matrix. The addition of a small amount of H2WO4 and Sb2O3 is critical for the formation of Na5W14O44 functional units because H2WO4 provides W for Na5W14O44, and Sb2O3 acts as a reducing agent that helps the formation of W5+ in Na5W14O44 under an air atmosphere. Furthermore, the NIR-shielding ability can be tuned by adjusting the concentration of Sb2O3 in the range of 0–1.5 mol % and of H2WO4 in the range of 4–6 mol %. The optimized composition containing 1.25 mol % of Sb2O3 and 5 mol % of H2WO4 exhibits excellent NIR-shielding ability (ΔT = 62.8%), high visible light transmittance (T max = 67.7%), and excellent thermal insulation. This performance is comparable to cesium tungsten bronze film-based glasses and much better than soda lime glass and ITO glass under sun irradiation. This study sheds light on fabricating energy-saving windows in a simple and cost-effective way with flexibility for fine tuning of NIR-shielding performance.

“…Other uses of the electricity are possible: for example, in water pumping or irrigation. Currently, there are also solar-fuel solutions underway to allow a cost-effective storage of solar electricity in synthesized fuels, which can be a great solution to circumvent the PV intermittency problem (Vieira et al, 2019;Lourenço et al, 2020). Moreover, neighboring agro-industries can share their electrical PV production in order to increase their energy efficiency and their environmental compliance (Latini et al, 2018).…”

The objective of this study was to analyze the cost-effectiveness of photovoltaic (PV) solar energy in wineries. The factors analysed were solar radiation, cost of PV installation, prices in the public electricity grid, size of the winery, power of installed panels, influence of the decreased consumption during weekends, and seasonality in the consumption. The study has been based on the European TESLA project, in which 39 energy audits were carried out in wineries in four European countries. A winery of 30,000 hL/year was characterized as a representative winery. The results showed that seasonality was key in the profitability of the system for self-consumption, related to the optimum power to be installed of PV. It was recommended to install, as an optimal PV power, the stable electrical power that is demanded in the daytime period. Optimizing the installed power of PV panels in the representative winery, the percentage of electrical energy consumption covered by photovoltaic energy varied between 16% and 22%. The percentage of the cost of electric energy covered varied between 18% and 24%, with payback values between 18 years (3.1 peak sun hours of solar radiation -PSH) and 10 years (5.6 peak sun hours of solar radiation - PSH). All the factors involved were analyzed.

“…The usage of CO 2 includes: reuse without conversion [ 5 , 6 ], conversion into a fuel, or an energy storage vector [ [7] , [8] , [9] , [10] ], or use as a raw material for the manufacture of added-value chemicals and materials [ 3 ]. Within the CCU technologies, in the class of CO 2 transformations into fuels or energy vectors, the conversion processes can be: biochemical, photosynthetic, thermo-catalytic, photocatalytic, electrochemical (which is the scope of the present work), and photoelectrochemical [ 1 , 2 , [11] , [12] , [13] , [14] , [15] , [16] ].…”
