Energy Sources - Economics and Politics
Episode 22 of The Science of Energy
Professor Wysession outlines some of the major economic and political forces shaping the development of the world's energy resources. You'll learn how hidden costs can affect the economics of supply and demand, how governments can incentivize and dis-incentivize energy industries,…
Energy and Human Civilization
Episode 1 of The Science of Energy
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…
Out of Thin Air
Part of the Series: The Mystery of Matter
One of science's great odd couples--British minister Joseph Priestley and French tax administrator Antoine Lavoisier--together discover a fantastic new gas called oxygen, overturning the reigning theory of chemistry and triggering a worldwide search for new elements. Soon caught up in…
The Chemistry of Food and Drink
Episode 15 of The Nature of Matter
Explore the chemistry of food and drink from the point of view of the cook and the consumer. What are the chemicals in an egg, a piece of toast, a slice of bacon, and other typical foods? How does cooking…
Hydroelectric Power - Electricity from Water
Episode 16 of The Science of Energy
Hydroelectric power continues to be the planet's largest renewable source of electricity. In this lecture, Professor Wysession discusses the benefits of hydroelectric power (no CO2 production, free fuel) and drawbacks (environmental disruption); how hydroelectricity generation works; run-of-the-river and impoundment-style power…
Energy Storage Technologies
Episode 19 of The Science of Energy
The sun doesn't always shine, and the wind doesn't always blow. So how do we store renewable energy from these and other sources for later? Focus on several basic (as well as high-performance and high-volume) technologies for storing the surplus…
The Science of Nuclear Power
