3 Humanity’s Top 10 Problems for the Next 50 Years 1. Energy 2. Water 3. Food 4. Environment 5. Poverty 6. Terrorism and War 7. Disease 8. Education 9. Democracy 10. Population Source: Nobel laureate, Richard Smalley

4 Objective Identify the needs, opportunities, and impediments for binational joint water-energy management at the Arizona/Sonora border

5 Outline  Growth, energy and water  Renewable energy resources at the border  Water resources at the border  Preliminary conclusions and next steps

16 Arizona has several promising areas located primarily from St. Johns northwest to Gray Mountain Arizona’s Wind Energy Resource

17 Geothermal Energy Mexico is 3 rd Largest Geothermal Country (over 300 sites identified) On May 2007, the Wagner Trench off Puerto Peñasco was surveyed by researchers from the Institute of Geophysics and the Institute of Marine Science using UNAM’s hydrographic nautical cruiser

20 Solar Potential in the US

21 Solar Potential in Mexico Solar radiation in Mexico is one of the highest in the world, allowing for an average solar power generation of 5 KW /m2 per day. A hybrid combined cycle power station, with a 25 MW thermo-solar system, is scheduled to begin operations in 2009, in Agua Prieta, Sonora.

32 3. Preliminary findings and next steps

33 Opportunities for Renewables at the Arizona/Sonora Border Growth = renewable energy opportunities Border area has highest North America solar resource Open space favors solar deployment Solar energy has the double advantage of being abundant and using least water
