    Adoption of green energy technologies in selected peri-urban and rural areas of Makueni and Machakos counties, Kenya
    (World Journal of Research and Review, 2023-05) Muloo, Samson; Kimiti, Jacinta M.; Mwinzi, Muusya; Muthike, George
    Many peri-urban and rural households usetraditional stoves which have low energy use efficiency leadingto wasteful use of woodfuel, increase in indoor air pollution andputting more pressure on biomass sources. Energy savingdevices have been introduced which are environmentallyfriendly and economical. The main objective of this study was toassess levels of adoption of green energy technologies in selectedperi-urban and rural areas of Makueni and Machakos Counties,Multistage sampling technique was used whereby; locations andsub-locations were selected purposefully. Households from foursub-locations were chosen using simple random sampling. Atotal of 214 households in the four selected study areas wereinterviewed. The study used questionnaires and interviewschedules for data collection. The collected data was coded andentered into the computer for analysis using the StatisticalPackage for Social Sciences (SPSS) and statistics and datasoftware (STATA) presented using tables. Utilization of metalcharcoal energy device was higher than that of other charcoaldevices in Unoa area (63.1%). Family size had a significanteffect on use of LPG (χ2 = 22.010, P = 0.001) and electric energytechnology (χ2 = 20.482, p = 0.002). The study results on theprediction of future charcoal energy devices adoption showedthat in the next 30 years’ majority of the households will stillprefer Kenya ceramic charcoal stoves to the maendeleo charcoalstoves. The outcome of the research is useful to manystakeholders including the government, Ministries ofAgriculture and Energy, Environmentalists, Market Suppliersof green energy devices and Researchers.

    Social-economic factors influencing the adoption of improved energy technologies in Makueni and Machakos counties, Kenya

    Many peri-urban and rural households use traditional stoves which have low energy use efficiency leading to wastefuluse of woodfuel, increase in indoor air pollution and putting more pressure on biomass sources. Energy saving deviceshave been introduced which are environmentally friendly and economical. The main objective of this study was toestablish social-economic factors influencing the adoption of improved energy Multistage sampling technique was usedwhereby; locations and sub-locations were selected purposefully. Households from four sub-locations were chosenusing simple random sampling. A total of 232 households in the four selected study areas were interviewed. The studyused questionnaires and interview schedules for data collection. The collected data was coded and entered into thecomputer for analysis using the Statistical Package for Social Sciences (SPSS) and statistics and data software (STATA)presented using tables. Data forecasting analysis was done using the Time series Autoregressive Integrated MovingAverage (ARIMA) time series model for the period 1991 to 2052. Family size had a significant effect on use of LPG (χ2 =22.010, P = 0.001) and electric energy technology (χ2 = 20.482, p = 0.002). The result of this research further showedthat for the respondent to get kerosene lamps, in Unoa, Kilili and Mung’ala, they travelled more than 1 km whereas inKilili, they mainly (18.6%) travelled 101 – 600m for the energy device. This showed a significant different in the distancetravelled in the four areas (χ2 = 86.194, P = 0.0001). The outcome of the research is useful to many stakeholdersincluding the government, Ministries of Agriculture and Energy, Environmentalists, Market Suppliers of improvedenergy devices and Researchers.
