Harvesting the globally available solar energy (or even just that over the Sahara) could theoretically meet all humanity's energy needs today (Hu et al., 2016; Li et al., 2018). Large-scale deployment of solar facilities over the world's deserts has been advanced as a feasible option (Komoto et al., 2015).
In fact, around the world are all located in deserts or dry regions. it might be possible to transform the world’s largest desert, the Sahara, into a giant solar farm, capable of meeting the world’s current energy demand. Blueprints have been drawn up for projects in and that would supply electricity for millions of households in Europe.
Large solar farms in the Sahara Desert could redistribute solar power generation potential locally as well as globally through disturbance of large-scale atmospheric teleconnections, according to simulations with an Earth system model.
For perspective, the sun delivers an mind-blowing 173,000 terawatts (TW) of solar energy to Earth continuously, more than 10,000 times the world’s current energy consumption. A study published in the journal Renewable and Sustainable Energy Reviews explores the feasibility of harnessing solar power from the Sahara.
But these developments have made Morocco partly dependent on Western Sahara for its energy supply. Morocco already gets 18% of its installed wind capacity and 15% of its solar from the occupied territory, and by 2030 that could increase to almost half of its wind and up to a third of its solar.
When wind and solar farms are deployed together in the Sahara, changes in climate are enhanced.

A microturbine (MT) is a small with similar cycles and components to a heavy gas turbine. The MT power-to-weight ratio is better than a heavy gas turbine because the reduction of turbine diameters causes an increase in shaft rotational speed. Heavy gas turbine generators are too large and too expensive for distributed power applications, so MTs are developed for small-scale power like electrical power generation alone or as combined cooling, heating, and power (.

The micro turbine generator is characterized by high efficiency, low pollution, low cost and modular design. The micro turbine generator power system comprises a gas turbine engine with a high speed electrical generator to provide power of 200kw and to have overall efficiency more than 78% by design of exhaust heat recovery systems.
A microturbine (MT) is a small gas turbine with similar cycles and components to a heavy gas turbine. The MT power-to-weight ratio is better than a heavy gas turbine because the reduction of turbine diameters causes an increase in shaft rotational speed.
In this mode, the microturbine generator is turned on and supplies power to the critical AC bus through LCM2. Typically, this microturbine will also be part of a CHP or CCHP system providing high-efficiency power that can reduce customer energy requirements.
Microturbine generators can be divided in two general classes: Recuperated microturbines, which recover the heat from the exhaust gas to boost the temperature of combustion and increase the efficiency, and Unrecuperated (or simple cycle) microturbines, which have lower efficiencies, but also lower capital costs.
The ARC generator provides smooth DC power output and may be fueled by any heavy fuel, even gas-station diesel. Key Design Features. The ARC micro turbine generator is ultra-compact – the entire device is the size of an ordinary toolbox and weighs just over 10kg.
In other applications, microturbines and engine generators are located off the grid in rural and remote areas where they provide the sole source of power (prime or continuous), or operate in combination with other sources such as photovoltaic or wind turbine installations.
