Solar: Beneficial for areas where the land use would not pose a significant problem. The sun radiation at these latitudes results in higher Watts per sq.m. This offers an opportunity for smaller PBP as well.
Middle east countries dominantly uses Solar and Wind energy to meet their power demand.These resources are very much abundant in those countries there by making them very much suitable. Hydro power is also being considered in countries with good water level. Use of biomass energy is not well appreciated except in few countries because of their complexity.
in the middle east the solar and wind resources are quite rich, but you should approach the question also by taking into account the access to the main transmission lines, the cost of transforming and synchronizing phases.
Every country in the Middle East has a special case, for example, many parts of Iraq and Saudi Arabia, solar energy can be very suitable, but northern Iraq can be suitable hydro-power. Jordan, Oman and some Arabian Gulf states can also use wind power. Bio-diesel is suitable for Palestine.
Mainly solar energy and wind turbines, also Hydropower in some countries like Egypt. Have a look at our paper below that investigate the use of renewable energy in the middle east to achieve nearly zero energy status.
