oa Civil Engineer in South Africa - Electricity for urban improvement : technical paper

 

Abstract

Electricity is the most efficient form of energy and ranks amongst the first three priority needs in developing communities. Urbanization is inevitable but necessary for economic growth. Access to affordable electricity is a key to urban improvement provided that it forms part of an integrated approach to service provision. The most immediate and much publicized benefit of electrifying a township is the improvement in the township's ground-level air quality. Smokeless fuels may offer a partial solution to the problem of township air pollution, but they will have little impact on SO emissions and they are at present more costly than traditional fuels. Greater use of electricity also serves to alleviate the impact on local natural resources. This is particularly so in rural areas where there is a heavy reliance on firewood as an energy source. This loss of trees to firewood increases the already serious rate of soil erosion as well as disrupting ground and surface water hydrology and the nutrient cycle. The environmental benefits associated with electrification are substantial, but to be effective the electrification scheme should be accompanied by projects aimed at facilitating access to electrical appliances and in particular promoting a voluntary move away from the use of coal-fire stoves.

Elektrisiteit is die mees doeltreffende vorm van energie en tel onder die eerste drie prioriteitsbehoeftes in ontwikkelende gemeenskappe. Verstedeliking is onafwendbaar en nodig vir ekonomiese groei. Toegang tot bekostigbare elektrisiteit is 'n sleutel tot stedelike hernuwing indien dit deel vorm van 'n geintegreerde benadering tot diensvoorsiening. Een van die belangrikste voordele wat elektrifisering vir dorpsgebiede inhou, is verhoging van die gehalte van die lug op die grondvlak. Rooklose brandstowwe lewer 'n beperkte bydrae tot die bekamping van lugbesoedeling, maar verminder nie die SO emissies betekenisvol nie en is oor die algemeen duursaam. Die gebruik van elektrisiteit verminder besoedeling en help om natuurlike hulpbronne te beskerm, veral waar hout as energievorm gebruik word. Elektrisiteit speel 'n beduidenisvolle rol in die bewaring van die omgewing. Dit is egter noodsaaklik dat elektrisiteitsvoorsiening gepaard moet gaan met die verskaffing van bekostigbare huishoudelike toebehore. 'n Program is nodig om huishoudings te help om vrywillig weg te beweeg van die gebruik van koolstowe.
