Chem 83 12/09/10 2 Causes of Un-sustainability In 1973 Roger Gymer suggested three causes of un-sustainability – Over-population, especially in developing countries – Over-consumption, especially in the developed countries (affluence) – The wide-spread use of advanced but imperfect technologies Chem 83 will focus on imperfect technologies Gymer, Roger G.,"Chemistry: An Ecological Approach", NY, Harper & Row, 1973, 756 http://maps.grida.no/go/graphic/energy_consumption_per_capita_2004 The least sustainable technology - use of fossil fuels for energy As population and affluence increase, the need for fossil fuels increases. Geochemical cycle for fossil fuels is too slow to be sustainable.

Wind 2. Concentrated solar 3. Geothermal 4. Tidal 5. Solar photovoltaic 6. Wave 7. Hydroelectric 8. Coal with C capture (untested) 9. Nuclear 10. Natural gas 11. Oil 12. Corn and cellulosic material Jacobson, M. Z. , Energy Environ. Sci., 2009, 2, 148 - 173 Sources 1-7 are sustainable since they are perpetual sources of energy based on wind, water, and solar (WWS). They serve as basis for his proposal for attaining sustainable energy.

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
