In line with sustainable development path, electrification with the aid of renewable energy resources is a key element for the developing countries. Cambodia with almost 85% rural population is one of the countries with high renewable energy resources but at the same time has a low installed...

Despite their important role in shaping the technologies of the future, public research and development (R&D) programmes are rarely based on systematic assessments of the environmental effects. R&D programmes thus allocate a huge amount of financial resources to projects, which potentially may...

We extend the WITCH model to consider the possibility to produce and trade electricity generated by large-scale concentrated solar power plants (CSP) in highly productive areas that are connected to demand centers through High Voltage Direct Current cables. We test the attractiveness of the CSP...

The need for renewable energy is a global demand due to both the economic factors and the environmental concerns. Malaysian government has been supportive on the research and development in the renewable energies. Renewable Energy Act (2011) and Sustainable Energy Development Authority Act...

The past 20 years have brought significant changes in the evolution of the energy sector in Romania. Even if it is considered a country with high potential for renewable energies, these are not fully exploited. European Union accession has determined significant changes in energy policy, energy...

The stricter worldwide emission legislation and growing demands for lower fuel consumption and anthropogenic CO2 emission require significant efforts to improve combustion efficiency while satisfying the emission quality demands. Ethanol fuel combined with gasoline provides a particularly...

The efficient utilization of the enormous crop-residue resources in China is crucial for providing biofuel, reducing the risk of environmental pollution, and increasing farmers' income. Examining the case of a crop-residue densification plant in the city of Jinzhou, China, this study examines...

Energy is the lifeblood of the modern world. Because of the negative environmental impacts and limited sources of fossil fuels, researchers are increasingly focusing on renewable energy sources, particularly solar energy due to its cleanliness and natural availability. Along with photovoltaic...

Wave energy conversion is a clean electric power production technology. During operation there are no emissions in the form of harmful gases. However there are unsolved issues considering environmental impacts such as: electromagnetism; the artificial reef effect and underwater noise....

This paper proposes an improved maximum power point tracking (MPPT) method for wind power systems. The proposed method combines hysteresis control with tip speed ratio (TSR) control using a power coefficient curve. It has fast dynamic characteristics with the TSR control using data obtained from...
