A MULTI-PERSPECTIVE ANALYSIS OF RENEWABLE ENERGY TECHNOLOGIES IN SUB-SAHARAN AFRICA: A Ghana Case Study Faculty Advisors Danny Hoffman Francis Abugbilla Evaluator Dr. Mohammed Amin Adam (Deputy Minister of Energy of Ghana) Coordinator Editors Visuals Editor Victoria Tyron Mel Suwuh Amy Nguyen Roshni Sinha Task Force Members Lorrin Johnson Hannah Schubert Austin Surber James Hennessey Clara Yardley Emily Asplin Ximena Perez Ricky Perry ACKNOWLEDGEMENTS As a whole, the members of the African Energy Intervention Task Force would like to express our gratitude for the individuals that helped realize and contributed to this report. We would like to thank Dr. Mohammed Amin Adam for taking the time and making the effort to come out to the University of Washington and discussing such matters with us. We recognize the hassle it must have taken to come to us and are excited to present our recommendations and consult with such an honorable and distinguished leader in the Ghanaian energy sector. To Frank Baffour-Ata, Gloria Adu Ofori, Amos Apam, and Mark Akologo Asigini, thank you for your invaluable insight on electrification and its implications within your communities. Your commentaries have unveiled a larger social problem at hand that tends to go unrecognized. Thank you to Dr. Scott Montgomery for your comprehensive presentation on energy in sub- Saharan Africa and opening our eyes up to the realities and complexities of the circumstances at hand. Thank you to our librarian, Theresa Mudrock, for being our inexhaustible resource for research help and being readily available to provide guidance. To Francis Abugbilla, we cannot express enough gratitude for your seemingly endless knowledge on the energy sector and on Ghana as a whole. We are so lucky to have had you on our team as a teaching assistant and appreciate the amount of work you have put into supporting us and bolstering our research. Your time, support, positivity, and insight have been vital to the success of our report. Last, but not least, we would like to thank Danny Hoffman, our faculty advisor, for the constant dedication and support that you have provided to this task force. Through weeks on end of editing and writers’ block, you have been there every step of the way, encouraging us. Without you to keep us accountable and in check, we would not have pulled this report together so seamlessly.
