Case Study: Energy Needs in Kenya’s Tea Sector

Kenya is one of the leading producers of tea – the largest in Africa and next to China, India and Sri Lanka one of the global leaders. However, tea processing requires intensive energy input and is often unsustainable as well as costly. Hence, the energy saving potential in the Kenyan tea sector is significant.

This week’s special is a case study on the energy needs in Kenyan tea factories. We want you to get an inside view on a real project. Take the view of the practitioner and learn hands on  about a variety of issues such as the results of a “real world” energy audit and its resulting recommendations. Check it out!

    I liked the posters for workers sensitization (can be put up in factories), besides giving a very good idea of what the EE topic is in that field and then what can be done, nicely shown in fotos (“good/bad practices”).

    Hope to recommend energy audit for a tea factory in the North Eastern part of my country to enhance its productivity.

    This an interesting reading materials. It is a great opportunity for me to deal with the prof on the way of maximizing energy efficiency.

    Improving energy efficiency can actually raise productivity in the Kenyan tea sector

    1. How can we not respect the natural habitant of a plant , fruit , when it comes to science ??
    “For example, irrigated land produces double or triple the outcome
    compared to rain-fed systems and accounts for 40 percent of the
    global cereal supply. The answer could just be to call for more
    irrigated land, but it may not be as simple as that. To identify
    effective changes, …..” so we need to prove of this ??
    2. how can we talk of solar energy in this country and that country , before making it possible in Africa ???

    3. I want to hear the biological , natural justice when we talk of energy efficiency?what is the use of knowing the nature , science, if we cannot apply it , but distort them due to national ,political etc interests
    4. If there should be peace in the world, UN should follow the truth strictly, than being a victim of politics around… if it is the plantation time for the farmers, who would protect them ? who would need them if we do not give the producers their rights but dictate them from capital ?? that is not fair … at the end, the world would collapse from injustice which we do not see the government tax as force labour , thief etc …..
    5. hey team , your duty to be there with such groups should be an example to such questions, ….

    The information on bioenergy in reader 3 was very good and the different technologies proposed fits very well for different enterprises whether large scale or small scale. Thanks

    What an interesting read!

    Does anyone know what type of fertilizers are being used for tea?

    Forgive me for talking politics here. Kenya is really serious about agriculture as compared to Uganda. Unfortunately, Ugandan dictator President Museveni has secured another 5 year term, after 30 years in office, and his government policies will not involve anything close to energy audits in agriculture. In Uganda, only the private sector currently would take energy audits seriously.

    An interesting case study.
    Interesting to know that the study is carry out in a department of Maths and not in an engineering department at the university (mechanical, electrical, agriculture etc.)

    I’m glad I have the case study.. It’s very informative

    It is interesting to note the amount of energy tea processing could take. Here in Nigeria, increased food availability will require improving energy efficiency in rice processing and in the baking industry. The application of heat recovery processes will create a new level of productivity and business opportunity

    Really a fascinating and eye-opening case study. Interesting to see how demand is increasing so much worldwide, and yet prices continue to plummet. One staggering statistic is that Kenya produces 10% of the world’s tea – and only 5% of it is consumed within Kenya itself! All that work, all that energy used, and decreasing prices are all the producers have to show for it.

    Wow! Never knew Kenya was making tea. I believe efficiencies in the powering system and other energy efficient technologies in growing economies of Africa will boost food production and remove poverty.

    I am happy this course gives insights to energy challenges bedeviling the Kenyan tea sector. It interesting to learn that 85% of total energy consumption in the Kenyan tea production processes is allotted to thermal energy, 15% to electricity. 15 % of total energy consumption on electricity constitutes 50% of total energy costs. This renders Solar PV, Wind energy conversion systems, bioenergy technologies and small hydros (renewable energy sources) as the best alternative of cut down energy costs on electricity. Adoption of solar thermal energy conversion technologies could be adopted in drying and curling of processed tea. Clearly synergy between Agriculture and energy when exploited and optimized would also be key in enhancing energy efficiency. There is a great future for the Kenyan tea sector with RE technologies.

    i feel kenyan tea sector is almost the same with brazil

    Very impress upon the energy consumption it takes to process tea.

    A very well synthesized case study, which makes a great illustration of the more theoretical content of the reader. It would have been great to have the same types of case studies more regularly, for other RE solutions as well.

    Just a thought here. Production of briquettes was one of the recommendations for increasing energy efficiency in the Kenyan tea industry. However, I thought briquettes production, on its own, was a very energy demanding process.

    The case study shows that there should be more campaign on EE. Some African governments should take cue from Ghana where there is a save a watt campaign. A country where population/energy is 5000MW/170m should concern herself more on spending on such campaigns than on jeeps and other luxuries for legislators and politicians.

    Interesting case, wonder how can the methodology be applied to similar initiatives
