This paper analyses the impact on renewable energy sources integrated into the Romanian power system on the electrical network operation considering the reduction of electricity consumption with respect to the 1990s. This decrease has led to increased difficulties in integrating the renewable energy sources into the power system (network reinforcements), as well as issues concerning the balance...

Given the role renewable energy is likely to play in the context of sustainable development, it is important to understand the relationship between renewable energy and economic growth. Therefore, this paper examines the relationship between renewable energy consumption and economic growth in a panel of sub-Saharan Africa countries from 1990-2011. Using a production function framework, the depe...

Directive 2009/28/CE establishes, as obligatory objective, a share of renewable energies on energetic consumption of 20%, in European Union, in 2020 However, such European normative gives freedom to member states in the selection of the renewable promotion mechanism that allows them to obtain that objective. In this paper, we analyze the main characteristics of the promotion mechanisms of renew...

China’s renewable energy power has developed rapidly in recent years. Evaluating the external benefits of renewable energy power can provide a reference for the Chinese government to set diverse development goals and to implement differentiated supporting policies for different renewable energy power types, which can promote their sustainable development. In this paper, a hybrid MCDM method was...

Future highly renewable energy systems will couple to complex weather and climate dynamics. This coupling is generally not captured in detail by the open models developed in the power and energy system communities, where such open models exist. To enable modeling such a future energy system, we describe a dedicated large-scale dataset for a renewable electric power system. The dataset combines ...

Renewable energy subsidies in the form of feed-in tariffs implicitly give investors the possibility to shut down their renewable power plants temporarily or permanently. This real option is especially valuable for electricity from biomass, an important pillar of European renewable energy goals. The shut-down option is similar to a put on agricultural commodity prices, while the costs and benefi...

Hydrogen is readily obtained from renewable and non-renewable resources via water splitting by using thermal, electrical, photonic and biochemical energy. The major hydrogen production is generated from thermal energy through steam reforming/gasification of fossil fuel. As the commonly used non-renewable resources will be depleted in the long run, there is great demand to utilize renewable ener...

Island electricity systems tend to rely heavily on the use of fossil fuels for the everyday supply of customer needs, so there are both significant economic and environmental benefits from the decarbonisation of these systems. One such key global environmental benefit is the anticipated reduction in CO2 emissions and its associated effects on climate change. In recognition, many islands are alr...

The potential trade-off between environmental protection and employment stability has been a concern in the literature. However, in the case of China, the employment issue has not been adequately addressed despite government’s big push on investing in renewable energy since 2007. This essay addresses the employment issue through estimating the relative employment impacts of renewable energy inv...

Non-renewable and renewable resources are imperfect substitutes due to technical and geographical constraints. What is the role of imperfect substitution on the optimal transition path to the clean technologies? We address this question by characterizing the optimal growth path and resource use of an economy. We show that the economy initially starts with using the non-renewable and renewable r...
