<span>The African renewable energy initiative (AREI), adopted in 2015 by nearly half of the countries, planned to install 10 GW end 2020 and 300 2030, which 100 would be wind. These countries have each their own national strategy defining rate electricity capacity, particularly wind, overall mix and/or 2030. This article aims assess implementation these strategies evaluating up-to-date ac...

In the real world, most countries generate electricity from fuel, which hasits own disadvantages. To minimize usage of fuels, economic, socialand environmental effects should be studied and focus given onthe development alternative power sources, such as solar photovoltaic(PV), wind energy, micro-hydro others. This paper focuses use photovoltaic generation in conjunction with turbinesto electri...

Affordable and clean energy is one of the sustainable development goals (SDGs) introduced by United Nations that are required to be followed all developed developing countries [...]

This article presents, a load management system is designed and implemented to integrate renewable energy resources (RES) (solar wind), which manage the according supply/demand user's priorities. The on hybrid integrating wind energy, solar utility supply, battery storage system. Load carried out via switching of loads. sources can also be turned ON OFF. During excess power, module works as an ...

abstract: enviromental concerns, improvements in renewable energy technologies, governmental incentives for the use of these resources, and increased t&d; costs, are the main factors driving the energy sector into a new era, where considerable portions of electrical demand will be met through widespread installation of distributed energy resources (ders). the virtual power plant (vpp) is a dece...

Performing functional integration of the free Lagrangian, we find the vacuum energy of a field. The functional integration is performed in a way which easily generalizes to systems at nonzero temperature. We use this technique to obtain the Casimir energy density and pressure at arbitrary temperatures.
