the share of dc-based renewable energy resources (rers) and electricity storage systems are increasing due to developments of smart grid technologies. moreover, the share of dc-based load has rapid growth due to significant developments of power electronic technologies. therefore, a more flexible power system is required for efficient integration of emerging loads and generators. in this paper,...

The International Renewable Energy Agency (IRENA) is an intergovernmental organisation dedicated to renewable energy. In accordance with its Statute, IRENA's objective is to "promote the widespread and increased adoption and the sustainable use of all forms of renewable energy". This concerns all forms of energy produced from renewable sources in a sustainable manner and includes bioenergy, geo...

This paper examines the use of policy mechanisms to increase renewable energy consumption within the United States. In order to effectively measure the change of renewable energy consumption, I analyze two initiatives that promote energy consumption from renewable sources and overall increases in energy conservation. Colorado and Washington had approved initiatives in the years 2004 and 2006, r...

China’s population has reached 1.25 billion, ranking No.1 in the world. Along with rapid economic increase during the past 20 years, there is increasing pressure on the energy industry from limited mineral energy resources and regulations for environmental protection regulations. The development and utilization of renewable energy is becoming one important option to realize sustainable developm...

in the science of operation research and decision theory, selection is the most important process. selection is a process that studies multiple qualitative and quantitative criteria, related to the science of management, which are mostly incompatible with each other. the multi criteria selection of a renewable energy portfolio is one of the main issues considered in multi criteria literature. i...

Renewable energy remains a contested topic in South Africa. This paper argues that South Africa can build on the momentum surrounding its introduction of a feed-in tariff by enacting policies that may, if given adequate funding and political effort, allow the country to be a world leader in renewable energy. Given a variety of renewable energy policy options for moving forward, a majority of st...

The use of renewable energy sources can provide a path toward sustainable development and regional energy independence. In particular, renewable-based energy autonomy constitutes a viable option in remote areas. This work presents a survey on the use of renewable energy as part of an energy autonomy plan on a Mediterranean island. The study also included personal communications with residents a...

In recent years, several countries and organisations increased their e↵orts on the use of renewable energy and electromobility [1]. Reaching the goal of a more environmentfriendly energy production together with less expensive transportation by using electromobility concepts is much more complicated as expected. Energy from renewable energy sources (e.g., wind or water) have the disadvantage of...
