Energy Conservation of Pakistan

1. This is the era of powered machines and appliances. Every household has some  sort of electrically powered appliances, be it a ceiling fan, washing machine or a refrigerator. These appliances are necessary in our day-to-day lives; it is difficult to imagine living without them. All of these tools consume huge units of electrical energy.  
2.            However many people do not know much about the production of electricity and the massive amount of pollution created  by the process. People just plug in there appliances and keep machines on unnecessarily, without giving a second thought. Those who pay the electricity bills might be more conscious of regulating energy use but those who don't are simply ignorant.
3.            Electricity is produced in pakistan in mainly three ways, Hydro-electric dames, nuclear power plants and fossil fuel fired thermal power stations. By far thermal power stations are the major contributors. Around 65% of the nation's electricity is produced by these power stations. The basic concept behind thermal power station is that a fossil fuel(usually refined petroleum) is combusted and used to turn liquid water to steam. The steam is blown through a turbine which is connected to a generator. The generator axle rotates and thus produces electricity. The steam is condensed and dumped into a river. Typical efficiency is about 48%. 
   

   There are many environmental disasters linked with these power stations:
1. Greenhouse and toxic gases released upon burning the fuels.
2. Largest areas of land needed to build power stations so many animal habitats become endangered.
3. Combustion releases sulfur dioxide and oxides of nitrogen, contributing to acid rain.
