A Review on Consequential Life Cycle Assessment in the Power Sector

2020

The existing policy for greenhouse gas (GHG) abatement aims at decarbonisation of the power sector. The interrelations between the power sector and other economic sectors raise a question of whether the GHG emission reduction policy in the power sector is as effective as it is claimed. Consequential life cycle assessment (CLCA) has been developed to assess the environmental impacts of any industrial/productive sector in relation with changes in the policy and its indirect impacts on other economic sectors. This review is conducted on CLCA studies in the power sector in terms of system boundaries expansion and socio-economic interactions and the ability to quantify indirect environmental imp…

The interaction between intermittent renewable energy and the electricity, heating and transport sectors

2012

In a global perspective, it is essential that the world transfers from fossil fuels to renewable energy sources in order to minimise climate change effects. As a part of such transition energy savings are also important, as they can decrease production costs effectively. The nature of such a change is that it has to be implemented on a local level. Energy saving technologies are placed with the demand decrease and renewable energy is typically distributed where the resources are. In some parts of the world, energy savings have resulted in a stabilisation of the energy demands, however in the world as such, demands are still increasing in buildings, transport and industry. Although the deman…

First proposal of a methodology for a preventive assessment of the acoustic impact of advanced landfills

2005

In this paper, the results of a preliminary study on the environmental noise pollution of a technologically advanced landfill to be realized in Sicily (Italy) are presented. The investigation has been carried out analysing, at the beginning, a simulating model suggested by the European Community. The method makes reference to the ISO 9613-2:1996 standard, which suggests a general method of calculation to assess the attenuation of sound during propagation outdoors. The simulation has pointed out the troubles in carrying out the noise pollution assessment of an advanced landfill, where several and different kinds of sound sources are present at the same time; it isn’t always possible, for exa…

Influence of the vehicle front shape inTeenage Cyclist-Vehicle Crash

2016

In this work the data, obtained for the three vehicles (sedan, SUV and Pick Up), tested in previous works, are compared. Following the results found in the literature, particular emphasis is done on the speed of the teenager cyclist head at the instant of impact and the diagrams of the head speed and the chest obtained in the simulations are shown. The speed of the head is that absolute, and this is used for processing the data and the subsequent determination of the best values of the three geometric actual parameters identified in front of the vehicle. Absolute speed is preferred because using the relative speed respect to vehicle, some amounts that cannot be disregarded are omitted from …

Seawater Desalination for Freshwater Production

2009

In the last decades more and more countries have experienced water scarcity problems, thus pointing at alternative non-conventional sources of fresh water. Seawater desalination has proven to be a reliable and economically sustainable water resource since the second half of the 20th Century. A number of well proven technologies already exist, with advantages and disadvantages making each of them more suitable in specific sites. Moreover, quite recently, coupling the use of renewable energy to the production of fresh water from seawater results in novel technologies, able to minimise the environmental impact that desalination processes can create due to their intense energy consumptions.

Economic impact of Ice Thermal Energy Storage Systems in residential buildings in presence of double-tariffs contracts for electricity

2009

Thermal energy storage is one of the most important methods of demand-side load management, thanks to the capacity of reducing significantly the peak power demand for air conditioning in buildings. Thermal Energy Storage Systems (TESS) are indeed used for producing and storing cooling capacity during off-peak hours (in particular during night hours) to meet the following day's air conditioning requirements. The current paper presents a study on the effects of the installation of Ice TESS for cooling on the power daily profile of residential buildings, and examines the economic repercussions on the electricity billing. With reference to this second theme, the paper examines, in particular, t…

Energy and environmental impacts of home automation components

2014

Life Cycle Assessment is applied to estimate the life cycle energy and environmental impacts of five components used in the home automation systems: an electricity meter, an actuator with an integrated current sensor, a web server audio/video, an interface with infrared emitter, a multimedia touch screen. For each component, the impacts related to “one unit of product” (selected as functional unit) are assessed following a “from cradle to grave” approach, including the manufacturing, operation and end-of-life steps. The results showed that the operation step gives a contribution higher than 54% on primary energy consumption and variable from about 54% to about 99% on environmental impacts, …

La sharing mobility è un approccio alla mobilità sostenibile dal punto di vista dell’impatto ambientale? Alcune considerazioni basate su un’analisi e…

2020

L'influenza della sharing mobility sulla sostenibilità ambientale non è stata ancora pienamente compresa. Da un lato la sharing mobility consente ai consumatori di assumere comportamenti che portano ad una riduzione delle emissioni di CO2 grazie, per esempio, alla minore produzione di automobili (riduzione dell’acquisto di auto) e alla riduzione dei chilometri percorsi dalle auto (condivisione della corsa e maggiore tasso di occupanti per veicolo). D'altra parte, l'implementazione della sharing mobility porta ad effettuare un numero maggiore di viaggi in automobile. Infatti, un certo numero di chilometri che vengono percorsi oggi dalle auto condivise, erano percorsi prima con mezzi di trasp…
