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…
Electricity - Ultimate Energy Converter
Episode 4 of The Science of Energy
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…
Energy - Forms and Conversion for Use
Episode 2 of The Science of Energy
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…
Chemical Energy, Biomass, and Photosynthesis
Episode 5 of The Science of Energy
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…
The Science of Nuclear Power
Episode 11 of The Science of Energy
Travel to the subatomic level for a fascinating exploration of how nuclear energy is generated. It's an eye-opening lecture that touches on everything from nuclear fission and radioactive decay to the inner workings of nuclear power plants and the attendant…
Solar Power and Electricity
Episode 14 of The Science of Energy
The biggest area of growth for solar energy: transforming sunlight into electricity with the aid of solar panels. Go inside the world of photovoltaic solar panels to find out how they convert sunlight into functional power. Also, take a closer…
Understanding Carbon Dioxide
Episode 10 of The Science of Energy
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…
Petroleum - Chemistry, Retrieval, and Use
Episode 7 of The Science of Energy
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…
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…
Coal: Convenient, Energy-Dense Fuel
Episode 6 of The Science of Energy
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?…
Fossil Fuel Energy - Issues and Concerns
Episode 9 of The Science of Energy
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…
Wind Power and Electricity
Episode 15 of The Science of Energy
Wind power is another growing source of renewable energy. First, discover how giant wind turbines provide us with energy. Then, get a brief history of how humans have tapped into wind's potential and the meteorology of how wind works. Finally,…
New Petroleum Directions
Episode 8 of The Science of Energy
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…
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…
Biofuels - Biodiesel and Ethanol
Episode 17 of The Science of Energy
Liquid biofuels like biodiesel and corn-based ethanol are the most rapidly growing forms of biomass energy in the 21st century. Here, survey some of the many intriguing chemical reaction routes that transform solid plant biomass into liquids with high-energy densities.…
Geothermal Energy
Episode 18 of The Science of Energy
Go deep underground for a look at geothermal energy. Topics include the energy budget of our planet, two main ways of using geothermal energy, five different technologies used for hydrothermal power systems (including dry steam power plants), and the concept…
Sunlight - Inexhaustible Energy Source
Episode 13 of The Science of Energy
Sunlight is a literally inexhaustible source of energy. Discover why (and how) the sun gives off light, how much sunlight energy the earth's surface gets in an average day, how much land we'd need to supply all our energy needs…
Energy Trends - Planning for the Near Future
Episode 24 of The Science of Energy
According to Professor Wysession, there's no easy solution to the world's energy future. Going through many of the sources explored in previous lectures, he estimates how much energy we'll need, what sources are (and will be) available to us, and…
