In addition to the fact that most renewable energies such as solar and wind energy have become more competitive in the global energy market, thanks to the great development in conversion technologies, it believes that renewable energy can play a crucial role in global environmental issues. However, in Palestine, the situation is different from anywhere else; renewable energy is not only an economic option, but an absolute necessity to get out of the energy crisis that Palestinian cities suffer from long years ago and continue nowadays.The cornerstone of the present research is focusing on the availability of renewable energy resources in Jenin Governorate (JG)—West Bank (WB)—Palestine. Two-year time-series of hourly solar, wind, biomass, and 1-year hourly electrical load data are used in the analysis in this paper. The energy potentials were estimated using System Advisor Model software (SAM), and the optimum combination and sizing of the hybrid renewable energy system were determined using Hybrid Optimization of Multiple Energy Resources (HOMER). The proposed Hybrid Renewable Energy System (HRES) consists of an 80 MW PV solar field, 66 MW wind farm, and 50 MW biomass system with an initial investment of $323 M. The proposed HRES generates 389 GWh/yr and is enough to meet 100% of the electrical demand of JG (372 GWh/yr) with excess in electricity generation of about 4.57% and the unmeet electric load is about 109.6 MWh/yr which is equivalent to less than 2 h off in a year. The estimated Levelized Cost of Energy (LCOE) was found as 0.313 $/kWh.

The energy consumption of the Libyan common house is estimated through the use of simulation namely, the TRNSYS simulation programme and other tools to reach the best solutions with the assumption of changing the behaviours of those buildings occupants into better behaviours that help in energy conservation. Using official data from The Ministry of Electricity and Renewable Energy, the Ministry of Housing and Utility, the Centre for Solar Energy Research and Studies (CSERS), measurements and a survey using a well-designed questionnaire, the relevant information is gathered and the research is conducted. The energy audit of the typical home has been conducted by using the simulation programme ‘TRNSYS’ and other tools, to identify the role and weight of each source of energy consumption in the energy savings strategy. The study provided a detailed analysis of the thermal and electrical consumption in Libyan houses. The energy audit showed that the total energy consumption was found about 16,500 kWh/year, and it is distributed by sources as 36% by electrical appliances, 24% by lighting the interior space, 15% for water heating, and about 13% for both cooling and heating the space. The estimated specific energy consumption is found as 238.7 kWh/m² floor area. As a result, it is found that it is possible to save over 6650 TWh of electrical energy by implementing the proposed strategic plan. These savings will have a positive impact on both the economy and the environment by reducing CO₂ emissions from power plants by 6.54 million tonnes of CO₂ per year, saving about 1.935 million tons of burning Diesel fuel and saving about $333.54 million as social cost of the CO₂.

Libya has a wide range of temperatures and topographies, making it a promising place to use wind and solar energy. This research evaluated many technologie
