Energy and Environment by Toossi Issues Big questions How much longer petroleum will last? What are geopolitical concerns? What are economical effects? What are the environmental impacts? Where are we going from here?

Energy and Environment by Toossi Concerns Useful energy is being more scarce. Population increases at an exponential rate. Industrializations demands more and more energy. Environmental problems becomes more severe with increases in energy consumption. Limited resources can impact social, cultural, and economical aspects of our lives. Global impacts could even be more serious.

Energy and Environment by Toossi Overview What is energy? Where is it coming from? What forms can it take?

Energy and Environment by Toossi What is Energy? Energy is a property of matter that can be converted into work, heat, light, or radiation. Phenomenological definition: “Energy is the capacity to do work”. Energy cannot be created nor destroyed, but can be converted from one form to another. When energy is used, its usefulness decreases by an amount equal to the work done. Although different forms of energy can have the same numerical value (quantitatively), they are not equally interchangeable (qualitatively) Energy is not power.

Energy and Environment by Toossi Where Does Energy Come From? Big-bang (10-20 billion years ago) released tightly packed mass of elementary particles. Created stars, galaxies and planets. (Source of the Gravitational or Potential Energy) Nuclear  Breakup of mass Solar  Radiation from stars (such as our Sun) Fossil and Biomass  Conversion of solar energy to mass Wind, wave, heat, geothermal, etc. are different manifestations of the same energy.

Classifications Mechanical Kinetic Wind Underwater currents Potential (gravitational) Hydroelectric (Waterfalls) Wave (surface, tides) Chemical Biomass Fossil Geothermal Nuclear Fission Fusion Sun-based Photovoltaic and solar thermal Wind Hydroelectric Biomass And even fossil fuels Earth-Based Geothermal Nuclear Earth-Moon-Sun Interaction Tides Energy and Environment by Toossi

Energy and Environment by Toossi Per Capita Energy Consumption

Energy and Environment by Toossi Consumption vs. Production Fifty years ago We were using one barrel of oil for every six barrels we found Today We are using four barrels of oil for every barrel we find. U.S. has about 5% of the World’s population, but uses 25% of the world’s oil.

Energy and Environment by Toossi World Energy Resources

Energy and Environment by Toossi Reserves The United States has: 2.5% of the world’s remaining oil 3.5% of the world’s remaining natural gas 20% of the world’s remaining coal At the current rate of consumption US will run out of Oil in 10 years Natural Gas in 12 years Coal in 300 years But don’t forget the exponential growth and market forces!

Energy and Environment by Toossi Exponential Growth T 2 =70/ Example: In how many years would the US population double. The US birth rate is higher than death rate by 1.3% T=70/1.3=41 years Census: 281 million (13.2% increase over 1990 data) 2041 Census (estimated): 562 million (probably too high)
