Small Island developing states: Overview about wind, solar and marine energy in Cuba
2019
The current economic, political, and social trends in Cuba indicate that energy sector will change in the future. The energy consumption will increase and Cuba, like most island nations, lacks a large energy resource base and satisfies most of its energy needs with imported fossil fuels. The aim of this work is a summary of renewable energy sources (solar, wind, bioenergy and marine) presented in the island and the development in the next society of the future.
Cumulative climatic stressors strangles marine aquaculture: Ancillary effects of COVID 19 on Spanish mariculture

Integrating multiple stressors in aquaculture to build the blue growth in a changing sea
2017
Fisheries currently represent the main source of animal protein intake worldwide, although catches of most commercial species are at or beyond maximum sustainable yields. Increasing production would require an excess of exploitation levels and aquaculture is expected to become crucial in sustaining a growing seafood demand. Nonetheless, many threats are expected to affect aquaculture and the increased production must evolve in a way that minimizes environmental and socio-economic impacts. The claimed sustainable development of human activities at sea (blue growth and economy) seeks for new joint analyses and solutions at (trans-)national systemic level should be planned and applied. To meet…
CLCA for Assessing Environmental Impacts of Power Sector in the GHG Policy Context
2020
Purpose: Current greenhouse gas (GHG) policy aims at reducing emissions from power sector. However, there are some known trade-offs of GHG emission reductions, in terms of other types of environmental impacts and impacts on other economic sectors. Consequential life cycle assessment (CLCA) has been developed to assess the environmental impacts of the power sector in relation with changes in the policy and its indirect impacts on other economic sectors. Methods: A systematic review of CLCA method is conducted in the power sector. CLCA studies since 2005 are reviewed in terms of obtained results and methodology to identify whether CLCA is a more suitable approach for assessing environmental i…
Analysis of the effects of climate change on the energy and environmental performance of a building with and without onsite generation from renewable…
2020
Climate Change is a priority, due to the large variety of implications and importance that it may cause in the next decades. In this context, the building sector is a significant contributor to greenhouse gas emissions. For this reason, buildings should be designed in such a way that they are responsible for fewer GHG emissions. In this context, the paper analyses the potential impact of climate change on the energy performances of buildings, with and without onsite generation from renewable energy, using a prototype building located in Messina (Italy) as case study. The analysis is based on Intergovernmental Panel on Climate Change RCP scenarios and the results confirm the already known ov…
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…
Wave and Wind Energy Systems Integration in Vietnam: Analysis of Energy Potential and Economic Feasibility
2020
Vietnam energy demand is currently growing at a very high annual rate, with the government being very interested in investments in renewable energies. Since the region with the highest solar and wind potential is far away from the big load centers, an investigation of offshore energy resources is here proposed. In this study, a review of previous energy potential assessments is provided. Moreover, the minimum feed-in-tariff to make the investments profitable is evaluated, showing that the current tariff for offshore wind plants is largely unattractive.
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…
An assessment of energy vulnerability in Small Island Developing States
2020
Abstract Small Island Developing States (SIDS) suffer from several structural characteristics that jeopardize their ability to achieve a sustainable energy future. Their reliance on imported fossil fuels exacerbates their exposure to external threats on international energy markets. Their energy systems are also exposed to internal disturbances that disrupt the proper production, transmission and distribution of energy. The aim of this paper is to investigate the extent to which island energy systems are vulnerable to shocks and internal dysfunctions over which they have no control. For this purpose, we build a composite index of energy vulnerability using the Multi-Layer Benefit-of-the-Dou…
