Morocco, which has no conventional energy resources, depends entirely on the international primary energy market to satisfy its growing demand due to its economic growth and demographic progression. The country imports the majority of its energy source supply. Morocco has implemented an important energy strategy that supports the country’s transition to renewable energy and energy efficiency th...

Optimal energy scheduling problem for single-user wireless communication system in fading channel is studied in this paper. In this schedule, the transmitter is powered by hybrid energy sources including both the conventional grid and an energy harvester collecting energy from nature and storing energy in a rechargeable battery. In this system, data arrival process, energy harvesting process an...

Renewable energy capacity in stand-alone power supply (SPS) systems has undergone a dramatic growth in Western Australian (WA) remote off-grid agricultural and pastoral regions. This growth was encouraged through capital cost subsidies of photovoltaic, wind turbine and enabling technologies. This research explores and quantifies the changes over time of energy demand and the rated output of ren...

Recent efforts to site renewable energy projects have provoked as much, if not more, opposition than conventional energy projects. Because renewable energy resources are often located in sensitive and isolated environments, such as pristine mountain ranges or coastal waters, siting these facilities is especially difficult. Moreover, the viability of different renewable energy projects depends n...

There is a substantial increase in energy demand in Turkey because of its growth of industrial development. Turkey’s present energy resources are insufficient and the need for energy is growing rapidly. Turkey does not possess enough conventional fossil fuel reserves, but possesses rich renewable energy resources such as hydraulic, solar, geothermal and wind. Among all, wind energy seems to be ...

To reduce the negative environmental implications (e.g., CO2 emission and global warming) caused by the rapidly increasing energy consumption, many Internet service operators have started taking various initiatives to operate their cloud-scale data centers with renewable energy. Unfortunately, due to the intermittent nature of renewable energy sources such as wind turbines and solar panels, cur...

A limited supply of existing fossil fuels together with the increasing demand for energy and the impending problem of the global climate change has motivated the need to incorporate a vast amount of renewable energy in our energy portfolio. Renewable sources are non-dispatchable sources that are both intermittent and uncertain in nature. At large penetration levels this variability can pose sig...

The utilization of renewable energies as an alternative for fossil fuels is considerably growing due to an increasing environmental concern and exhaustion of fossil fuels [1-3]. Transportation electrification is one way to replace or reduce fossil fuels with renewable energy sources. Several propulsion systems including hybrid electric vehicles and plug in hybrid electric vehicles have been int...

Background Renewable Natural Gas (RNG) is pipeline quality gas that is fully interchangeable with fossil natural gas but is produced from a renewable feedstock and can be used as a 100% substitute for, or blended with, conventional natural gas streams [1]. RNG is an important alternative fuel that can help the State of California meet several GHG and renewable energy targets. As a transportatio...

the aims of this study were to assess the energy and economic flows of biodiesel production from olive pomace oil using transesterification method with ultrasound waves. for this purpose biodiesel production from this feedstock were examined through a life-cycle process with considering five main stages of agricultural production, transportation, olive oil extraction, pomace oil extraction and ...
