Résumé partiel
Energy affects all aspects of development : social, economic and environmental, including livelihoods, access to water, agricultural productivity, health, population levels and education. Public schools spend a lot of money every year on energy bills. Currently, they are experiencing an exponential increase in student enrolment which puts more pressure on energy needs. This study focuses on cost benefit analysis of different energy sources used in public secondary schools in Mtito Andei Division, Makueni County. The specific objectives are to : (1) establish the sources of energy used in public secondary schools, (2) investigate the factors determining the choice of the energy source(s), (3) assess environmental and socio-economic impacts of major energy sources and (4) conduct cost benefit analysis of major energy sources. The study used Survey Research Design (SRD) and a census survey, with all 30 schools in the study site studied via questionnaire administration, observation, interview and photography for data collection. Both descriptive and Benefit Cost Ratio analytical procedures were used. The study findings showed that firewood was the most popular cooking energy source with all (100%) schools using it while charcoal came second (23%) followed by LPG gas (10%) and paraffin (7%). Only 3% of the schools used electricity for cooking. The over reliance on firewood for cooking is expected to have negative environmental consequences in the study area. Electricity was the most popular source of energy for lighting (60%) followed by solar energy (27%) and paraffin (7%). These are expensive sources of energy. An investigation into forms of low cost energy technologies as perceived by the respondents revealed energy saving stoves (87%), solar power (27%) and energy saving bulbs (10%).
