Week 4: Energy Efficiency

Welcome to Week Four of the Powering Agriculture MOOC!

Great work on last week’s assignment! We are looking forward to learning about your approaches to calculate the PV panel size for solar powered irrigation – and also reading up on the peer-review comments. By the end of this week our experts from TH Köln will evaluate your group assignment on a pass/fail basis and provide a collective feedback report.

Explore this week’s material, enjoy and Keep On Rocking!

    week 4 is very interesting, just from the video I have learnt a lot of things. didn’t know that conservation efficiency and energy efficiency are different

    interesting and very important theme “Energy/ System Efficiency”. Excellent case study which can be applied in most developing countries. Thanks for the update!

    Week 4 is very interesting and its give highlight about energy efficiency ! by increasing our farm energy efficiency its possible to get profit in sustainable manner !!

    The Kenyan case study reveals opportunities for energy conservation and efficient use.Though use of biofuel in terms of wood combustion should be reconsidered as it is a leeway to deforestation.Another source of GHG emission.

    interesting case study! didn’t know kenya produced tea…

    We never ever have to forget this : ” Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
    If we do ignore this and keep on BAU scenario, it directly implies that we are very greedy as we are living at the expense of our children and grand children …

    Week 4 Case Study was an interesting read. It gave me an insight into the ‘Kenya Tea Factory’ and the high level of energy intensity in which it operated daily to produce tea and to remain a leader in tea production in Africa and third in place globally. The case study clearly exposed the lack of energy efficient measures in the factory and the recommendations made to improve energy efficiency, thus reducing costs at various levels or stages of the production process. The cost of energy was truly high, and in a commercial sense to be profitable, such costs will be passed on the final consumer in the supply chain. I enjoyed the material, and I noticed the installation of renewable energy in the Kenya tea factory would be a good idea, backed buy efficiency measures too.

    Week 4 is rich. It pertains directly to my interest.

    The reading material for this week was very informative. I did not know that only 20-30% of the original coal energy is used in the end of the production chain. So far all reading materials were very interesting. I am looking forward to the upcoming ones.

    This helped me gain a much broader appreciation of energy effieciency.
