Abstract


Most countries around the including UAE share the same pattern ofenergy consumption, where residential sector is taking a larger percentage withthe exception of some few countries, however generation pattern in mostcountries around the world is virtually from fossil fuels as indicated in IEAreport 2011 and 2013. For cities to be smart and sustainable its sources ofenergy must also be sustainable and efficient. The device that is expected tobe the most appropriate candidate for developing a sustainable and efficientheat/electricity generation system based on the result of the research workpresented in this paper is Fresnel lens, considering it`sattractiveness due to it`s favourable material properties including; lowweight, mechanical strength, temperature resistance, and inexpensivemanufacturing. TheExperimental methodology was based on measurement of stagnation temperature atthe focal point of Fresnel lenses of different configurations as a function oftime and solar irradiance in some tropical countries (Nigeria and Malaysia),irradiation distribution from the lens`s surface to it`s focal point underinvestigation was found to be high for efficient use of photovoltaic modules insustainable agriculture, green transportation, green building and communication.Highest temperatures achieved with these lenses approached temperatures ~ 1000°C and higher for efficient use in heat and electricity generation. Fresnellens concentrators were determined to be the most desirable candidates forthermal and electricity generation when compared to reflective concentrators. HoweverFresnel will play a vital role in carbon mitigation as well as generating huge carboncredit thus helps to a large extent in making the dream of smart city becoming real.Keywords: (Fresnel lens, carbon footprint,sustainable city, sustainable agriculture, green transportation, greenbuilding)
