The study aimed to identify the general characteristics of the study sample, and to identify the most important economic requirements for the transition to a green economy as the entry point for sustainable development. And cost-benefit analysis of the use of solar pumps and solar roofs compared to fossil energy, and a sample of workers in non-governmental organizations was taken. In North Sinai Governorate, and at the time of study, 63 individuals were available to the researches.for analyzing the obtained data and information, the researcher used the following statistical variables: arithmetic mean, standard deviation, standard degree, total weights, and weighted average.The study concluded that solar energy is a clean energy for the environment that is used in many fields, including solar lighting poles, as it does not bear high operating costs for the state as in the case that it provides infrastructure costs such as excavation and backfilling, as well as the cost of cables extending along the streets, and the loss of electrical energy that It occurs as a result of the long distance. In addition, it is easy to maintain, as it does not need to separate the entire line when there is a problem in one of the columns, not due to maintenance of one column and finding faults as happens in traditional columns, but it needs periodic cleaning of the solar cells so that the system does not lose its usefulness.
