The aim of this article is to show the opportunities for penetration of new renewable energy sources into the Brazilian energy mix, enabling it to continue generating a high quantity of clean energy compared to the world average. Different scenarios for the evolution of such sources in Brazil...

This article presents a review of methodologies allowing for the calculation of agricultural biogas potentials on a regional level. A definition of theoretical, technical and economic potentials as well as methods for their calculation are provided. The review of the state-of-art studies in this...

The current European Union (EU) energy policy seeks to reach a balance between sustainable development, competitiveness and secure supply. In this sense, the EU energy policy sets the target of a 13% share of renewable energy sources (RESs) for Belgium. Several instruments have been implemented...

The article describes sustainable development of Lithuanian economy and transition of fuel and energy after the integration of Lithuania into the European Union (EU), covering the period 2004–2012. In 2004–2008 Lithuanian gross domestic product (GDP) increased approximately 1.8 times and...

The growing concerns about climate change and security of supply opened way to a significant investment in the exploitation of RES (renewable energy sources) for electricity generation. The possibility of achieving 100% RES systems is being debated but concerns about costs, storage and backup...

This paper analyzes the concept of a decentralized power system based on wind energy and a pumped hydro storage system in a tall building. The system reacts to the current paradigm of power outage in Latin American countries caused by infrastructure limitations and climate change, while it...

The building sector is one of the largest energy consumers. Even though cooling needs do not contribute a large share to the overall energy demand in temperate climates, recent trends show a tendency of large growth. This growth is related to two main drivers: cheap and affordable...

There are regions in the Republic of Croatia (underdeveloped, devastated by war, depopulated, as well as islands and mountainous areas) which are still disconnected from the electricity network or where the current network capacity is insufficient. In addition, these regions have good renewable...

The paper presents the stochastic optimization algorithm that may eventually be used by electric energy suppliers to coordinate charging of electric-drive vehicles (EDVs) in order to maximize the use of renewable energy in transportation. Due to the stochastic nature of transportation patterns,...

The Belgian nuclear phase-out law imposes closing down in the 2015-2025 period seven nuclear power plants (NPPs) producing more than 50% of the domestic electricity. This creates an urgent problem in the country because of the absence of well-defined capacity-replacement plans. Though a...
