The combustion of fossil fuels in thermal power plants has greater environmental impacts like air pollution and global warming. Additionally, the import of oil is a heavy burden on the poor economy of the country. Pakistan is a country with huge renewable sources; wind energy being the major one. This paper elucidate the cost-competitiveness of wind power with the conventional thermal power plants. In this regard, Levelized estimated cost of a 15MW wind power plant is compared with three types of conventional thermal power plants, namely (i) Oil-fired thermal power plant (ii) Natural gas-fire combine cycle power plant (iii) Diesel oil-fired gas turbine cycle 100MW each. The results show that the cost of wind energy is lowest with Rs. 3 /kWh. It is concluded that the wind power is cost-competitive to the conventional thermal power plants in Pakistan. The cost estimation for wind energy is lowest of all others with Rs. 3 /kWh.

The Transportation network is responsible for a large amount of the hazardous emissions causing global warming and air pollution problems worldwide. Bio-diesel is one of the most important suitable oil to eliminate greenhouse gases emissions and alternative of the fossil fuels. The demand of energy is increasing on day-today basis, because enhancement in industrialization and population. Bio-diesel (mono-alkyl-esters) is the substitutive fuel, which obtained through the process of transesterification of monohydric alcohols with triglyceride oil. Bio-diesel oil obtained from the renewable sources of fuel having no properties of degradable and toxic. The waste cooking oil, such as sunflower, canola, soybean, coconut, corn oil, fish oil, rice bran, chicken fat, and algae can be used for preparation of Bio diesel, by adopted this process, the dependency on petroleum-based fuel decreased partially. This paper will focus on production of bio diesel oil from algae (micro algae and macro-algae) having higher efficiency of photosynthetic process by the other biomass products. The algae are best sources for the production bio-diesel, and having best yielding stock for bio-diesel. The macro algae is available in abundant in the form of seaweed at coastal area of Balochistan which extends over 750 kms. The micro algae cultivated near the beach of coastal area either in wet land (ponds) or in saline lagoons. It will provide main source of income to the people of coastal area inhabitants and consequently, it will provide good opportunity to the Govt. in order to reduce the rate of unemployment within Balochistan. The national bio-diesel project can be launched in the coastal area, taking the stakeholders in confidences. It will play an important role in alleviation the rate of poverty among the people of Balochistan. Secondly, it will save the fertile land of other provinces, which are more suitable for cultivation of food commodities instead of fuel producing species; otherwise, it will adversely affect the economy of the country, due to the shortage of food commodities. The pollution in air as well as in aquatic life of marine will reduced. It will produce the best result, by adopting of Bio-diesel fuel in Transport sector.

Fossil fuels like oil, coal, and natural gas are having limited supplies and are depleting fast. Both energy security and environmental concerns have resulted in inclination towards renewable energy sources. Biodiesel does not contain petroleum, but it can be blended with petro-diesel in various mix levels. This research investigated biodiesel produced by the use of cheap waste cooking oil, collected from the local market of Nawabshah, Pakistan. The collected waste oil was converted into biodiesel by trans-esterification process at PCSIR Laboratory, Karachi. The fuel samples were tested in a diesel engine test bed unit at the Thermodynamics Laboratory of Quaid-e-Awam University. Biodiesel blends were compared with the conventional diesel fuel. The comparative analysis of the performance parameters concluded that brake specific fuel consumption of B30 (biodiesel 30%+diesel 70%) mix...

reclaimed waste heat from domestic cooking system and analyze the
financial impact about all the wastage of available energy. The main
object is to recover waste heat from the system and transfer the lost
energy from the source back into the useful work and also to make
the energy conversion process as efficient as possible. There are
various techniques in use, for recovery of waste heat from various
systems under different situation. This work is carried out on
prototype Domestic pressure Cooker used in the houses on daily
routine basis. This paper involved the thermodynamically analysis
regarding (a) the wastage of energy due to the dispersion of flue
gases which carry out considerable amount of heat energy. (b) Heat
losses through the heat conduction from the cooking Pan’s walls to
the environment. (c) Improper adjustment of the flame. (d) Enthalpy
losses through the exhaust steam.
Some techniques are suggested in this work, in order to minimize
the losses of waste heat energy, and also tried to exhibit the
suggestions for further work in future.
