A hybrid power plant including a solar central receiver for receiving solar radiation and converting it to thermal energy. The power plant includes a molten salt heat transfer medium for transferring the thermal energy to heat exchanger. The use of fossil fuels should be reduced in near future due to their limited resources and increasing ecological impacts. Therefore, increased interest and incentives have been created for development of electricity supply utilizing renewable energy such solar energy, which has long-range potential and is applicable in most geographical regions Libya is located in the center of North Africa. The vast majority of the country is located in the Sahara Desert, which is characterized by its high potential for solar energy. This study provides an evaluation study for the solar power plant with a capacity equal to 70 GW/year to support generating electricity. The System Advisor Model (SAM) model system, developed by the National Office of Renewable Energy (NRE), was used to assess the plant's active and economic performance.

Tripoli City, the Capital of the Libya, has experienced far-reaching changes in spatial and socio-economic patterns during the last few decades, supported by crude oil revenue. The changes have produced far-reaching increase in municipal solid waste (MSW) generation and electricity demand. Open landfilling is the dominant method of MSW disposal in the city. This research aims to assess the value of Waste-to-Energy (WTE) facility as a solution to MSW landfill problem and as a renewable source of electricity. two WTE scenarios were developed: complete incineration; incineration with recycling. The results show that Tripoli has the potential to produce about 57 MW of electricity based on incineration scenario; about 32 MW based on incineration with recycling scenario; in the year 2030. These values are based on theoretical ideals and help in identifying the optimal WTE techniques for each city.

In this study, an attempt was made to develop a response surface model to optimize loss due dry flue gas (LDG) of boiler efficiency at Sussa’s desalination plant. The most significant operating parameters studied were combustion air flow rate (MC), mass flow rate of fuel (MF) and flue gas temperature (TF), and their corresponding ranges were (80.3-91.5 Kg/hr.), (6-6.5 Kg/hr.), and (309.1-374.6 °C) respectively. The MINITAP software version 16 was used to design the experiments (DOE), to mathematically evaluate the effect of the operating parameters on the LDG and to set the optimal operating parameters that provide a minimum value of the response (LDG).  The best response value was analyzed using the response surface and contour plots.  The optimal operating parameters were 80.3kg/hr for combustion air flow rate, 6.50 Kg/hr for mass flow rate of fuel, and 309.10 for flue gas temperature, and their corresponding LDG value was 4.317.4 kJ°C /kg . It could be concluded that historical-data RSM is a promising statistical technique that could be used confidently in optimizing operating parameters that would minimize LDG
