    The Kenyan Government is committed to promoting electricity generation from Renewable Energy Sources (RES) with priorities in solar, wind, hydros, biomass and geothermal. In this study, the potential of solar energy as a local source of clean and renewable resource for Nakuru was investigated. Global daily radiation intensity covering period 1986 to 2010 and air temperature records from 1960 to 2008 for Nakuru obtained from archives of the Kenya Metiorological Department (KMD) were subjected to a number of statistical analyses that included: Quality control and Homogeneity tests, temporal, time series as well as empirical statistics. The characteristics examined for the resource include diurnal; seasonal and annual power expectations. Results revealed that Nakuru is a moderate to high solar energy potential region, with an average daily insolation of 6.9kWh/m2. It was also revealed that the energy reaching the surface in this area is season dependant with December-February season receiving the highest amount of 678 kWh/m2 and September-November season receiving the least amount of 602.6kWh/m2. The study concludes that Nakuru is endowed with abundant solar energy resources, favorable for tapping at both small and medium scale levels. These levels are quite convenient, particularly for isolated households in the rural and pre-urban settings of the town. The solar energy potential revealed by the study is bound to go a long way in fulfilling the vision of Kenya energy policy as elaborated in sessional paper No4 of 2004.

    Social-economic factors influencing the adoption of improved energy technologies in Makueni and Machakos counties, Kenya
    (World Journal of Advanced Research and Reviews, 2023-04-07) Muloo, Samson M.; Kimiti, Jacinta M.; Mwinzi, Muusya; Muthike, George M.
    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.
