Energy is a fundamental quantity in our universe, however, it is an elusive substance that can't be held, seen, or felt. Yet, everything in daily living relies on energy - lighting cities, transporting vehicles, warming homes, cooking food, powering computers and the internet, playing music and enabling radio and television.

This talk will present the latest scientific understanding about the earth's total energy budget and glimpsing into the future. Several fundamental energy questions are answered: Will the world run out of energy?, How does hydrogen, not a fuel itself, fit into the picture?, What is carbon sequestration and does it matter?, and What might the U.S. energy system look like in 2050?

Dr.John Ziagos

Geophysics PhD, Deputy Department Head for Atmospheric, Earth, and Energy Department
Lawrence Livermore National Laboratory

Dr. Ziagos is the Deputy Department Head for the Atmospheric, Earth, and Energy Department at Lawrence Livermore National Laboratory (LLNL). He is responsible for achieving a vigorous energy and environment research portfolio through the technical and business leadership of 200 scientists, engineers, technicians and administrative staff. John has been at LLNL since 1990. Prior to becoming the Deputy Department Head, he was the Superfund manager for 10 years at the Laboratory's main Livermore Site and the Site 300 high explosives test facility, successfully negotiating Record of Decisions with the U.S. Environmental Protection Agency (EPA). In his 30-year energy, environment and earth sciences career he has managed both large and small teams of scientists and engineers and worked for the University of California, the U.S. Geological Society (USGS), the U.S. Department of Energy, successful start-up companies (FINDER now owned by Schlumberger), and major energy corporations (BP/SOHIO). In addition, John managed the construction and operation of a $110M, 50MW geothermal power plant in southern California working for Geothermal Resources International. He has many years experience in a variety of geotechnical field projects, including terrestrial heat flow studies in central Mexico, earthquake research at the USGS on the San Andreas Fault, geothermal and petroleum exploration and production in Alaska and the Gulf Coast. John's technical expertise includes groundwater restoration and remediation, subsurface structural and stratigraphy analysis, petrophysics and interpolation/characterization methodologies specifically for reservoir modeling, with automated history matching. Dr. Ziagos holds a BS degree in mathematics and physics (1970) from Western Illinois University, and a PhD in geophysics (1983) from Southern Methodist University.

John has been both a high school and middle school science teacher and, throughout his career, has continued to teach environmental science, including Environmental Management at UC Berkeley Extension, Federal Facilities Superfund Restoration at UCLA Extension, Environmental Restoration for a private company, and a teacher symposium offered through the UC Davis Edward Teller Education Center on Energy Technology and the Environment. He has extensive experience in public speaking and was the keynote speaker at the 2006 Kern County Science Fair speaking on Energy Technology and Climate Change. John also lectures on the Future of Energy Technology at the Livermore Laboratory's annual Science on Saturday series.

During his career John has continued to be involved with the local community through the Pleasanton Leadership Program, Executive Board of Directors and Environmental Day Coordinator, EPA Technical Assistance Grants, the LLNL Environmental Restoration Community Work Group, Alameda County Watershed, Natural Resources/Wildlife Subcommittee, and Zone 7 Water District Flood Control Citizens Group.

Dean Reese

Physics and Biology Teacher
Tracy High School

Dean Reese received his undergraduate degree in physics from the University of Massachusetts in Amherst. Currently, he is the Science Department Chairperson at Tracy High School and has been teaching there since 2002. He teaches IB Physics, Conceptual Physics, and ELL Conceptual Physics. He has been a Master Teacher for LLNL’s Education Program since 2007 and currently instructs in the Computer Simulation Teacher Research Academy. Dean has co-presented with various scientist in many Science on Saturday Presentations. In 2006, Dean had a DOE Academies Creating Teacher Scientists internship where he interned for 3 consecutive summers at the Center for Accelerator Mass Spectrometry at LLNL. In 2011, Dean was awarded the Cortopassi Family Foundation Excellence in Science Teaching Award. He is a dedicated advisor for the Tracy High Earth Club, Scientifically Speaking Club, and Computer Programming Club. Dean is a master instructor for the SIMMS (Secondary Integration of Modeling in Math and Science) Project with the intent of developing computer modeling skills for high school science and math teachers within the San Joaquin County. Prior to becoming a teacher Dean was a soldier in the United States Army National Guard.
