    good handout and powerful information

    This course is an eye-opener to the power of renewable energy!

    After looking at Figure 2 on page 6, I found something to be quite interesting. The first part shows ‘Fertilizer’ for the Pasture and ‘Fuels’ for the feed. Does that mean the fuels to transport the feed to the cows? Isn’t that what the pasture is for? Couldn’t that section (Fuels/Feed) be cut out completely if the cows were always on pasture? With that said, the ‘Fertilizer’ going into the pasture would then be cut out because the cows would be creating their own fertilizer.
    One and a half steps cut out just like that.

    It’s quite interesting to know how different sources of energy work in powering the agricultural sector. I am looking forward of getting a special insights into solar PV for irrigation!

    The breakdown of the design procedure is insightful

    I am really impressed on the amount of input we are provided with. The material is very well structured and understandable. I also like to possibility to learn more via the extra links and documents. Thank you!

    Really helpful information on renewable energy resources – great examples and helpful examples of how each type of RE could be used in practice.

    Example on milk value chain (Figure 2) and Table 2 RE options showed me big opportunity to improve energy efficiency in the future.

    This doc is powerfull it opens our mind so that we could be good at clean energy projects

    This a highly illuminating resource. The application of renewable energy in agriculture beyond farm lighting is a great value to smallholder farming especially with respect to farm gate pre-processing activities like removal of field heat or pre-drying of grains, etc,

    The use of smart micro hydropower system/turbine in non-flowing water bodies will be more adaptable for instance if it could be used in dug ponds and not just flowing river. This means a technology that will kinetize a water body ordinarily still (potential energy) and will enable farms that are distant from streams create multiplier productivity for on-farmactivities and pre-processing or processing activities. Bbenefit from this technology is the increase energy efficiency and renewable resourcing on farms for a larger number of such farm estates in rural settings.

    Page 9 (Referencing Table 1): “An integrated energy source will
    eventually reduce waste, costs and increases the sustainability of a
    product or process.”

    How long is “eventually”?

    Page 11: “To
    find out about the potential around your area, look for renewable
    energy projects nearby or talk to your national institutions to access
    studies on different potentials.”

    Here in the Northeast US, we have solar and wind. There are incentive programs through state and federal governments for putting solar panels on houses. Ironically, sometimes property taxes then go up.

    With our numerous hills and mountains, one can see those GIANT 3 blade turbines collecting energy from the ridge line. It can be quite majestic at times.

    What’s in YOUR area?

      We’ve got the scorching sun that we can take advantage of. In northern Nigeria, it’s so bad, we get sun burnt and never realise it. We could take advantage of the sunlight for the SPIS. A couple of local communities have tried this system to provide water for the household useuse but they never maintain it. These projects go to waste after a couple of months, but I’m sure farmers wouldn’t allow such project perish.

    I think evaporative coolers using Solar PV panels and PV-powered refrigerators (solar chillers) is a fantastic idea. I intend to contact the SunChill team. I think there is great opportunity for implementation in Uganda.

    Interesting read, diving into the key constructs. My questions on the available technologies are starting to get answered. This is getting more informative and mind tickling particularly for the assignment.

    The information is very useful and can be used when opting on which type of energy efficient technology to use

    bit hard to listen to him :) but awesome work. Keep it up

    quite challenging on its own with all these formulaes, but the practical video simplified understanding. The reader really give a broad and interesting view into the various solutions.

    I am however wondering about the cost of these solutions, and how these can be tailored at different level of the community in developping countries to support the value chain development of agricultural products.

    At last, I finished the manual. In Nigeria, we need at of these solar powered dryers for Cassava flakes (garri) and meat (kilishi) drying. It has come to the notice of the public that garri most especially can get contaminated by things as unimaginable as you can think… We need cheap and easy to fabricate solar dryers and I would embark on a project to make that possible through the NGO I intern with. I’d NE needing the support of anyone who can be of help. Thanks

    I just watched the Smart Hydro Power Video from Page 14 (I’ll watch the 10min video tomorrow).

    Anyway, what happens if there’s a flood? How are the turbines attached to the river bottom? What happens if a drought occurs?

    Inquiring minds want to know!

    it’s so interesting! we should really pay attention to details when designing a strategy in order to achieve the optimal development of it. And I haven’t thought about how important is actually the sun for the acquirement of energy here in Earth.

    So now that I’ve finished watching the 10min Micro Hydro Power video from page 14, I’m curious about safety. The plant itself looks pretty good, minus all of the exposed moving parts. What’s the risk of fire due to in-house installation and the wires from the power plant to the homes that are receiving the electric.

    Also, my cousin’s ex-husband is from Indonesia so I sent him the link to see if he can provide some more information.

    I just finished watching the videos offered on page 15.

    In regards to the last, Energy Yield Calculation, is the 28.3% power worth it? Especially when other variables are factored in like fossil fuels used for turbine transportation, human energy used for construction, trees cut down for installation, etc.

    With regards to the water pump for irritation on page 17, what happens to the water when it’s not needed and the wind is still blowing? Are there tanks to hold the extra water or does it get wasted?

    additional reading on Windmill system tool is confusing power and energy. There is need therefore to change that. The author gave expression for the power and called it energy. Also, he should note that we write kilo-Watt as kW and not Kw.

    I think that the sunchill project is a very important step for the storage of food. It would be great to have a simple technology, which works without electricity. I am just sorry, that the information content about the technology of the web page is not really high.

    All the technologies are so interesting and helpful to higher the state of living of so many people, but often fail because of the lack of maintenance:
    – people need to be taught how to handle the systems
    – it is important to use materials, which can be found in the area and which are affordable

    The NASA link on page 23 does not work for me. Has anyone else managed to open it? Is it the same site as the NASA link provided in the additional reading material?

    the reading material summarizes the renewable energy technologies, and it’s a good reference

    Excellent explanation, is my first lesson solar energy and I understood everything !!, accompaniment of practical examples of the application of the technical concepts especially in agricultural value chains makes perfect learning.
    Thank you very much for sharing the practical and successful cases (https://poweringag.org/docs/opportunities-agri-food-chains-become-energy-smart), this gives us an impetus to develop ideas to apply in each local context our territories.
    P.S. Thank you for each link, I’ve Explored and Contain valuable information !!

    Very interesting read. Easy to read and very concise

    Tremendously enlightening literature. I can already see ideas and ways that efficient uses of energy can be used in such industries as banana production and livestock produce in my country.
