In recent years, countries have begun to reduce the consumption of fossil fuels and replace them with renewable energy sources in an effort to mitigate the effects of fossil fuels on the environment and save money as well as increase energy security. There is no doubt that the regulatory component represented by policies and legislation are the most important means to achieve the desired goals and strategies. The UAE does not yet have a renewable energy law and is still working on the Electricity law No.2 of 1998, which did not address the issue of electricity production from renewable sources and treat with electricity generated from sustainable sources as electricity produced from fossil fuel sources and what implies high coast compared to non-renewable source in short term. As besides, the UAE did not produce a map representing the best locations for installing large-scale renewable energy projects. There are few studies that touched on renewable energy legislation in the Arab world and in the UAE in x particular. During this study, the Electricity Law of the UAE was analyzed and special recommendations were made for renewable energy legislation in the light of these analyzes. The experience of the State of Jordan, Palestine, Morocco and some Western countries such as Germany in the field of renewable energy policies was used as recommendation for UAE's policy makers. It was concluded that the UAE does not encourage the private sector to join renew renewable energy projects due to its application of the joint venture model with the private sector, and government subsidies on household sector are not an incentive for individuals to implement renewable energy projects. The proposed solution is the implementation of some incentives and mandatory policies in the field of renewable energy such as Feed-In-Tariff , Wheeling policy and Net-Metering in conjunction with the quota policy, as well as the exploitation of the lands of the Empty Quarter to establish renewable energy projects and through the establishment of free zones, exempted from taxes and customs duties, allowed the activates of generating green electricity inside and wheeling it outside The thesis has developed the suitability map for the installation of large- scale CSP projects among United Arab Emirates using GIS data and Multi-Criteria Decision Method (MCDM) technique. the suitability map is composed of multi-maps (layers) of solar irradiation (Direct Normal irradiance (DNI) component), land slope, protected areas, land use, proximity to water bodies and power grid as well as the roads. This thesis has highlighted the most-suitable location as well as the non-suitable location among UAE to install CSP projects using ArcGis software. The study has shown that UAE have multi-hotspot locations that can be used for CSP projects installation as well as great solar energy potential that could attract more investments in the same sector.
