lessons learned

• International conference: ICREDC06

• MOU with a local NGO and Renewable Energy

Power System Design and Implementation.

• Project Inauguration

• Low cost “Turn Key” system adaptable to

other countries

• Conclusion and Future Plans


INTRODUCTION

Initial “Chat” between the President of UDC and the President of the Federal Democratic Republic of Ethiopia in 2004

Why doesn’t UDC engage in some form of water development project in Ethiopia?


Feasibility study through fact finding and lessons learned

• Meeting with Addis Ababa University, AAU officials and the

engineering faculty

• Meeting with the Ministry of Water Resources

• Meeting with a recommended local NGO which is experienced

in water project implementation in rural areas

• Visit of a solar powered water pumping station near the city of

Debret Zeit

• Visit with a City Administrator of the town of Wollisso, in Oromia

State’s, West Showa zone

• Meeting with the president of a local regional business school of

Ambo.


And…

Meeting with the President of FDRE

(an environmentalist…)


•Inverter curse!

•Grounding problems..

ETHIOPIA at a glance (in 2004)

Shortage of Potable water !


But Lots of Hydropower!!

Potential: Hydro 45,000 MW (11 Dams 1 Super Dam ) Wind 10,000 MW Geothe 5,000 MW


• Need of pump systems for shallow wells

(Avoiding Inverters, and batteries)

• Need to have an alternative energy

source to replace the gasoline operated

generators

MAIN FINDINGS:


Meeting with the NGO Hope2020

• What can you do to help us?

• Is Hope2020 familiar with RE work?

Five U.S.-Ethiopian Universities Partnerships To Receive U.S. Embassy Seed Money Grants

Addis Ababa, March 9: The Embassy of the United States of America today announced the results of a

small grant competition to provide seed money for innovative partnerships between U.S. and Ethiopian

universities. Five grants of $15,000 each will be awarded to new research, academic exchange and

curriculum development partnerships between:

1. Wollo University/Langston University -- Development of a Center for Small Ruminant Artificial

Insemination

2. Wolaita Sodo University/University of Florida – Archeology and Cultural Heritage Management

Training

3. Jimma University/Cornell University – Clean-burning Cookstove Development Project

4. Hawassa University/Washington State University – Anthropology Teaching Support and Research

Collaboration

5. Bahir Dar University/University of the District of Columbia – Research Partnership on Renewable

Energy

U.S. Ambassador Donald E. Booth noted: “Ethiopia’s visionary expansion of tertiary education

throughout the country opens up many educational opportunities. The U.S. Embassy is delighted to

provide initial funding to support new and innovative collaborations and partnerships between higher

education institutions in Ethiopia and in the U.S.”

The seed money competition was first announced at the December 2011 conference on “Building

Sustainable U.S.-Ethiopian University Partnerships,” sponsored by the U.S. Embassy and the Institute of

International Education, with support from the Ministry of Education. The objectives of the grant

competition were to a) grow mutually beneficial and sustainable partnerships between U.S. and Ethiopian

universities and colleges, b) introduce new higher education institutions to U.S. and Ethiopian

partnerships, and c) strengthen the skills and experience of faculty and administrators in both countries in

developing and implementing partnerships.

Microbusiness opportunities to be explored

(sustainability)

Disseminate the “Turn-Key” Solar/Wind solution

to other developing countries (Kenya, Haiti etc..)


Good news!

And is getting cheaper!!

SOLAR ENERGY is ABUNDANT!!
