Purpose The purpose of this paper is to assess the wind resource and energy potential of the Sanghar site for minimizing the dependence on fossil fuels and improving the environment. Design/methodology/approach The Sanghar site wind shear coefficient and turbulence intensity factor are investigated for a period of a year. The two-parameter k and c Weibull distribution function is used to analyze the wind speed of the Sanghar site. The standard deviation, coefficient of variation, wind power density and energy density; and capacity factor was assessed for a period of a year. The economic assessment of energy/kWh is investigated for the selection of appropriate wind turbines. Findings The mean wind shear of the Sanghar site was found to be 0.2509. The mean wind speed was found to be 4.766, 5.534 and 6.121 at 20, 40 and 60 m above the ground level. The mean value of the k parameter was observed to be 2.433, 2.777 and 2.862 at 20, 40 and 60 m for a period of a year. The Weibull c m/s parameter was found to be 5.377, 6.245 and 6.906 m/s at 20, 40 and 60 m. The major portion of values of standard deviation was found to be in between 0.1 to 2.00 at 20, 40 and 60 m. The mean wind power density values were observed to be 88.33, 93.5 and 110.16 W/m2 at 20, 40 and 60 m; respectively, for a period of a year. The mean coefficient of variation was found to be 0.1478, 0.1205 and 0.1033 at 20, 40 and 60 m; respectively. The mean energy density was found to be 476.75, 683.08 and 866.33 kWh/m2 at 20, 40 and 60 m; respectively. The mean capacity factor for different wind turbines was ranged between 18 to 24.83 for a period of a year. The economic assessment showed that wind turbine B has the minimum cost (US$) 0.0484/kWh. Practical implications The assessment provides the solution to sustainable energy generation which reduces the consumption of fuel and the effect of fluctuating price of fuel in the world market on local consumers. Social implications Wind energy may have social implications including environmentally friendly, consistent supply of energy during the peak summer season, less unit per cost, etc. Originality/value The Sanghar site is new and assessed for the first time in this research work. The Sanghar site is suitable for installing utility wind turbines for energy generation at the lowest cost.

“…The recent studies of wind resource and economic assessment of this region has been given in following literature (Hulio, 2020;Hulio et al, 2021aHulio et al, , 2021bHulio and Jiang, 2020). The wind resource and energy economic assessment of Gharo site has been carried out at 10, 30 and 50 m. The authors concluded that the site is suitable for isntalling the utility wind turbines (Hulio, 2021). In another wind resource assessmnet of Karachi Port Trust (KPT) has been carried at 10 and 30 m that showed site has potential for energy output (Hulio and Jiang, 2020).…”

Pakistan is a developing nation that emphatically needs low cost energy resources to cope up with the economic growth. The major portion of energy is being generated by conventional methods. To generate energy through conventional methods is an expensive business that has direct impact on socio economic conditions corresponding to the rising of prices of energy in Pakistan. Another major implication of generation of energy by conventional source is increasing of circular debt that crossed Rs: 10 billion. The objective of this paper is to assess the potential of renewable energy resources and role of Government in policy formulation. The assessment showed that there is large availability of renewable energy resources. However, the formulated renewable energy policy does not have effect on the practical realization of renewable energy. This research study provides further insight owing to power policies, renewable energy transition and challenges of renewable energy policy facing in Pakistan. After potential assessment of renewable energy resources, the recommendations have been put forwarded that would help to promote renewable energy, as a key indicator in the sustainable growth and accelerating the energy transition to future energy perspectives of country.

The design and fabrication of a digital solar-powered DC induction cooker come with numerous advantages, including high efficiency, almost two times the existing technologies. Its portable compared to the existing technology, its efficiency comes with low power consumption i.e. all power that is generated is transferred, at least 80 % of the power generated and above all it is aimed at designing a stand-alone DC induction cooker. It encompasses the use of a heating element powered by a DC source from energy trapped from the sun, with the aid of PV cells, battery, charge controller, and relays using AT MEGA 328P microcontroller for switching and control purposes. The design enables the selection of time for either warming or cooking. The heat for cooking and warming is produced by the Nichrome wire (element) according to the time set. The temperature at 100oc was obtained at 45 minutes. The system’s efficiency can be improved in the Nichrome wire (element) and a corresponding increase in the backup storage and the PV modules. The total energy generated from the solar system was 5760W at 24VDC with average sunshine hours in Bida as 8hours and the battery used is 2 pieces of a 12V-100AH which was connected in series to produce 24VDC. The design done for the induction cooker was rated at 400W. This means that the induction cooker can run for a minimum of 6 hours without any means of charging. It was observed the solar can sufficiently charge the battery two times in one day if it is been discharged
