“…Moreover, new players such as pro-sumers, excluded from the old centralized generation model, have been introduced by distributed RES deployment calling for a bi-univocal Grid. In this field, EU resolution [9] promoted this new actor, i.e., the PROducer-conSUMER, in the energy context, firstly, as off-grid solution to improve energy-access for those areas considered not economically profitable by big energy utilities to build energy networks, and secondly, to allows a free choice to citizens about their own energy supply [10]. Consequently, the link between the availability of local resources and sustainability considerations move towards the so-called Zero Kilometer Energy model [11].…”

Abstract:Urban waste management is one of the most challenging issues in energy planning of medium and large cities. In addition to the traditional landfill method, many studies are investigating energy harvesting from waste, not as a panacea but as a foreseeable solution. Thermo-chemical conversion to biogas, or even bio-methane under certain conditions, could be an option to address this challenge. This study focuses on municipal solid waste conversion to biogas as a local energy supply for the cities. Three urban models and their subdivision into urban areas were identified along with a typical Organic Fraction of Municipal Solid Waste (OFMSW) matrix for each urban area. Then, an energy analysis was carried out to provide an optimization map for an informed choice by urban policy-makers and stakeholders. The results highlighted how the urban context and its use could affect the opportunity to produce energy from waste or to convert it in fuel. So, in this case, sustainability means waste turning from a problem to a renewable resource.

“…Electricity often originates from bio-resources such as urban waste wood, crops, and forest residues, which have the advantage of less emission of GHG compared with fossil-fuel incineration (Antizar-Ladislao and Turrion-Gomez, 2010;Pimentel et al, 1981). Representative technologies used to convert the biomass to either power or heat include homogenization, gasification, and anaerobic digestion via direct and co-firing combustion systems (Kothari et al, 2010).…”

The renewable energy has been investigated as an alternative resource to resolve the demanding consumption of conventional hydrocarbon energy, to minimize the environmental impact, and to secure the sustainability for decades. The exploitation of renewables is often hampered due to the intermittence, site-dependency, and the lack of engineering experiences. The objective of this paper is to introduce the characteristics of various renewable energies and to examine the roles for geotechnical engineers. Beginning with the synopsis of worldwide energy consumption, an overview is presented for renewable energy sources of air, water, heat and organics in terms of associated technologies and issues related to geotechnology. The compressed air energy storage system related to geomaterials is introduced, and the challenges that may need to be advanced by geotechnology are proposed. This paper shows that Optimized site characterization, advanced geotechnical tools, and real-time monitoring systems are necessary for the geotechnical construction of renewable energy systems.

Abstract:Research investigating the potential of producing biofuels from algae has been enjoying a recent revival due to heightened oil prices, uncertain fossil fuel sources and legislative targets aimed at reducing our contribution to climate change. If the concept is to become a reality however, many obstacles need to be overcome. Recent studies have suggested that open ponds provide the most sustainable means of cultivation infrastructure due to their low energy inputs compared to more energy intensive photobioreactors. Most studies have focused on strains of algae which are capable of yielding high oil concentrations combined with high productivity. Yet it is very difficult to cultivate such strains in open ponds as a result of microbial competition and limited radiation-use efficiency. To improve viability, the use of wastewater has been considered by many researchers as a potential source of nutrients with the added benefit of tertiary water treatment however productivity rates are affected and optimal conditions can be difficult to maintain year round. This paper investigates the process streams which are likely to provide the most viable methods of energy recovery from cultivating and processing algal biomass. The key findings are the importance of a flexible approach which depends upon location of the cultivation ponds and the industry targeted. Additionally this study recommends moving towards technologies producing higher energy recoveries such as pyrolysis or anaerobic digestion as opposed to other studies which focused upon biodiesel production.
