For decades, society has been changing towards an energy mix that enhances the use of renewable sources and a more distributed generation of energy. The agricultural sector is included in this trend, which is why several studies are currently being carried out focused on the use of solar energy in greenhouses. This article aims to demonstrate the viability of a greenhouse that integrates, as a novelty, semi-transparent amorphous silicon photovoltaic (PV) glass (a-Si), covering the entire roof surface and the main sides of the greenhouse. The designed prototype is formed by a simple rectangular structure 12 m long and 2.5 m wide, with a monopitch roof, oriented to the southwest, and with a 35° inclination. The greenhouse is divided into two contiguous equal sections, each with an area of 15 m2, and physically separated by an interior partition transparent wall. The surface enclosure of one of the sections is made of conventional glass, and the one of the other, of PV glass. How the presence of semitransparent PV glass influences the growth of horticultural crops has been studied, finding that it slightly reduces the production of vegetal mass and accelerates the apical growth mechanism of heliophilic plants. However, from a statistical point of view, this influence is negligible, so it is concluded that the studied technology is viable for horticultural production. The energy balance carried out indicates that the energy produced by the PV system is greater than the energy consumed by the greenhouse, which shows that the greenhouse is completely viable and self-sufficient for sites with the adequate solar resource.

“…As a result, ethanol is extensively used throughout the world [2,43,44]. Brazil can produce affordable ethanol fuel from the fermentation of sugarcane to supply its transportation sector [45][46][47][48][49][50], whereas the US produces ethanol from corn grain to supply its domestic demands [51][52][53]. However, the use of feedstock from first-generation biofuels such as sugarcane and corn grain to produce ethanol has raised some concerns as it can compete with human food supply [43,54].…”

Several studies on ethanol as a biofuel have been comprehensively carried out. Today, a growing interest in longer chain alcohols has emerged due to their favourable physical and thermodynamic properties. Butanol or butyl alcohol with 4-carbon structure (C4H9OH) is a more promising biofuel as it outweighs methanol and ethanol in several ways. The production cost of butanol has been gradually reduced, and rapid progress in the development of its production technology has allowed butanol to be produced more effectively. However, studies on the effect of butanol on gasoline or spark ignition (SI) engines are not as comprehensive as the abundant research of ethanol. This paper highlights recent novelty and contribution of butanol addition in SI engine. Results of new approaches on the engine’s performance, combustion and emission characteristics are summarised. Reviews from this paper suggest that there are some gaps in the addition of butanol found in the literature. Thus, several encounters and forthcoming research directions are outlined in the final section of this review article, highlighting several possible contributions that have not yet been carried out using butanol as a biofuel in a gasoline engine.

“…Corn ( Zea mays L.) stover is mechanically harvested on 0.81 million ha in the United States for livestock feed and bedding purposes but is also considered a primary feedstock for cellulosic biofuels (Mitchell et al., 2016; Schmer, Brown, Jin, Mitchell, & Redfearn, 2017). The relative affordability of corn stover as an animal feed compared to other forages and its potential as a low‐carbon transportation fuel may result in increased stover use (Locker et al., 2019; Redfearn et al., 2019). Corn stover and other crop residues provide essential soil benefits such as wind and water erosion protection, soil C cycling, and nutrient storage (Jin et al., 2017; Wilhelm et al., 2010).…”

Corn (Zea mays L.) residue or stover is harvested as supplemental feed for livestock and is a potential feedstock for cellulosic biofuels. Limited information is available on corn stover removal effects on grain yield under different irrigation rates, nitrogen (N) fertilizer rates, and practices to maintain soil carbon (C) and minimize soil erosion. We evaluated potential interactions between irrigation rate (full or limited), C amelioration practices (cover crop, surface‐applied manure, or no amelioration practice), fertilizer N management (125 or 200 kg N ha−1), and stover removal (residue removal or no residue removal), on no‐till continuous corn grain yield located on a silt loam soil in south‐central Nebraska (2011–2018). Stover removal increased (P = .0017) grain yield by 1.02 Mg ha−1 and grain N uptake compared with no stover removal. Manure increased corn grain yield by 899 kg ha−1 compared to either the control or cover crop with stover removal while C amelioration practices did not affect grain yield under stover retention. Grain N concentration was higher (P < .0001) with stover removal (13.2 g kg−1) than residue retained (12.7 g kg−1). Partial factor productivity (grain yield/N rate) was highest for manure treatments with residue removal. The farmgate N balance (N applied − N removed) from stover removal was negative, yet grain yield was not affected after eight growing seasons. Grain yield increased with stover removal and manure application resulting in a cost‐effective C amelioration practice whereas incorporating a winter cover crop resulted in similar grain yield as the control.
