“…A comparison of the environmental impacts of fossil fuel-based technologies (FFTs) are presented by (Atilgan and Azapagic, 2015) in Turkey and (Tan et al, 2010) in Singapore. (Ramjeawon, 2008) presents LCA results of electricity from bagasse in Mauritius, and (Silva 40 et al, 2012) in Brazil.Comparisons between FFTs and RETs performed by (Hondo, 2005) in Japan or (Smith et al, 2015) in Singapore, can help select the most appropriate technologies for an electricity generation system.Papers also provide LCA results by country, as Mexico (Santoyo-Castelazo et al, 2011), Portugal (Garcia et al, 2014) or Greece (Theodosiou et al, 2014). (Herbert et al, 2016) developed a series of GHG emissions assessments for selected countries, from which four types of countries were identified.…”

Due to the high reliance on fossil fuels in the electricity production and transport sectors, completing the energy transition holds a particular importance for non-interconnected territories. The environmental impacts from electricity generation are mainly imputed to fossil fuel based technologies, for instance in the case of French insular territories. This paper summarizes the present electricity situation in these territories and aims to determine their different emissions and environmental impacts through a life cycle assessment (LCA) approach. To deliver 1 kWh of electricity to the power grid from the studied regions, the electricity mix is defined as the functional unit. The results refer to a life cycle cradle-to-gate electricity production model. The impact categories discussed in this paper are related to global warming potential, acidification potential, tropospheric ozone precursor potential, and the cumulative energy used. Due to its high share of renewable energies sources, French Guyana has the lowest greenhouse gases (GHG) emissions per kilowatt-hour produced compared to the other islands (373 g CO2-eq/kWh, 4.29 g SO2-eq/kWh and 2.65 g NMVOC-eq/kWh). Combined with other social, economic and environmental parameters, these results will be also used to determine the typologies of islands in order to define a common energy strategy for each group.

Framing Microgrid Design from a Business and Information Systems Engineering Perspective

et al. 2019

Microgrids are decentralized distribution networks that integrate distributed energy resources and balance energy generation and loads locally. The introduction of microgrids can help overcome the challenges of global energy systems. Despite this potential, the information systems domain has seen limited research on microgrids. This paper synthesizes research on elements of microgrids for electric energy. Interviewed experts maintain that technological microgrid solutions have been solidly developed; nevertheless, the lack of economic and business consideration is stalling their deployment. The authors argue that business and information systems engineering research can provide integrated perspectives that connect technology and markets. Consequently, the authors derive a framework from an extensive interdisciplinary literature review that structures the academic state of the art on microgrid design and could guide associated information systems research. The framework comprises four layers: energy technology and infrastructure, information and communication infrastructure, application systems, and governance. The authors evaluate the framework in interviews with 15 experts from industry and three from academia. Their feedback allows to iteratively refine the framework and point out research directions on microgrids in business and information systems engineering. Keywords Microgrid Á Renewable energy sources Á Framework Á Literature review Á Research agenda Á Green IS Á Energy informatics 1 Motivation and Research Questions In a global Delphi study on future trends in energy systems, 64% of 350 experts from around the world argued that ''by 2040 the energy supply system will be structured in a cellular way: interconnected cells and 'islands' of the size of a city or medium-sized region will generate their energy from solar power, wind power, storage units and a minor share of conventional reserves'' (BDEW et al. 2016). In this future energy system, microgrids will play an important role. A microgrid is a small, decentralized distribution network comprising electricity generation, loads, and storage devices. It presents itself to the main power grid as a single controllable load that can also operate in islanded (self-sufficient) mode (Liang and Zhuang 2014). According to Hossain et al. (2014), microgrids are ''one of the most practical solutions for green and reliable power.'' Microgrids' ability to mitigate energy systems' challenges, such as integrating renewable energies (Hatziargyriou et al. 2007), simplifying demand side management

“…For all technologies mentioned here, the use-phase makes a substantial contribution to the overall life-cycle environmental impact. Since the increased attention for the concept of decarbonistation of the built environment, several LCAs have also been conducted that analyse e.g., zero-energy buildings or even neighborhoods and micro-grids [45][46][47].…”

Comparison of the Greenhouse Gas Emission Reduction Potential of Energy Communities

et al. 2019

In this research, the greenhouse gas (GHG) emission reduction potentials of electric vehicles, heat pumps, photovoltaic (PV) systems and batteries were determined in eight different countries: Austria, Belgium, France, Germany, Italy, the Netherlands, Portugal and Spain. Also, the difference between using prosuming electricity as a community (i.e., energy sharing) and prosuming it as an individual household was calculated. Results show that all investigated technologies have substantial GHG emission reduction potential. A strong moderating factor is the existing electricity generation mix of a country: the GHG emission reduction potential is highest in countries that currently have high hourly emission factors. GHG emission reduction potentials are highest in southern Europe (Portugal, Spain, Italy) and lowest in countries with a high share of nuclear energy (Belgium, France). Hence, from a European GHG emission reduction perspective, it has most impact to install PV in countries that currently have a fossil-fueled electricity mix and/or have high solar irradiation. Lastly, we have seen that energy sharing leads to an increased GHG emission reduction potential in all countries, because it leads to higher PV capacities.
