1. Energy and Human Civilization
30m
How much energy is required to power human civilization? What is it that makes our cities, factories, homes, and cars so energy inefficient? How can the average individual affect energy directions? Find out in this overview of how energy touches everything from engineering and economics to biology, chemistry, and geophysics.
2. Energy: Forms and Conversion for Use
30m
Energy is a fundamental part of our universe-in a sense, the universe is energy. Here, Professor Wysession introduces you to the many fascinating forms energy takes, including potential, kinetic, mechanical, and thermal energy. He also explains how energy is measured to make you more fluent in "energy-speak" for the coming lectures.
3. Heat: The Transfer and Flow of Energy
30m
One of the first forms of energy that humans learned to use is heat. You'll examine three ways heat flows (radiation, convection, conduction); make sense of the heat flow equation and the concept of entropy; and go inside the inner workings of a "heat engine" machine.
4. Electricity: Ultimate Energy Converter
30m
Discover what makes electricity such an attractive vehicle for energy. Learn how electricity can come from oil, coal, solar, and other forces, and how electricity travels through wires with the help of voltage. Also, examine recent advances that make it easier for us to choose where we source our electricity.
5. Chemical Energy, Biomass, and Photosynthesis
30m
Turn now to chemical energy, the potential energy resulting from the position of atoms within molecules. After an overview of photosynthesis (perhaps the universe's most amazing form of energy conversion), learn how combustion transforms biofuels into light and heat, and how energy density affects the transportation of biofuels like petroleum.
6. Coal: Convenient, Energy-Dense Fuel
30m
Understand one of energy's most polarizing topics: coal. Where does coal come from, and how does it develop? What makes coal "clean" or "dirty"? Why do certain nations have the largest coal reserves? What are some advantages to coal energy? And how does strip mining impact the environment?
7. Petroleum: Chemistry, Retrieval, and Use
30m
In the first of two lectures on petroleum, examine the science behind this common fossil fuel: how it's formed, how it's found and processed, how it's transported, and how it's used. You'll also gain insights into related topics, including geologic structures such as anticlines and the growth of the petroleum industry.
8. New Petroleum Directions
30m
Peer into the future with this look at some of the newest trends in oil and gas production. Professor Wysession explains the difference between conventional and unconventional oil, the geology of oil sands and oil shales, and the risks of fracking (which can cause earthquakes and other serious damage).
9. Fossil Fuel Energy: Issues and Concerns
30m
Fossil fuels, while abundant and portable, come with a significant list of drawbacks. Focus now on the various financial, environmental, and health concerns surrounding our continued reliance on fossil fuels (such as coal fires and oil spills). Then, examine some recent technological and legislative efforts to combat these problems.
10. Understanding Carbon Dioxide
30m
Carbon dioxide is a pollutant so significant to human civilization that Professor Wysession devotes an entire lecture to it. If CO2 is only 0.04% of the atmosphere, how can it be so harmful? Is global warming a natural process? What actions can we take to reduce the dangers of CO2?
