The Science of Energy - Resources and Power Explained
Energy is, without a doubt, the very foundation of the universe. It's the engine that powers life and fuels the evolution of human civilization. Yet for all its importance, what energy really is and how it works remains a mystery to most non-scientists. For example:
  • Where does most of…
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 to make you more fluent in "energy-speak" for the coming…
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 how to think realistically--and optimistically--about our energy consumption.
The Nuclear Fission Fuel Cycle
Episode 12 of The Science of Energy
Professor Wysession explains how uranium is used to make electricity through the process of nuclear fission, from acquiring uranium-bearing rocks to disposing of leftover nuclear waste. Afterwards, learn some of the upsides of nuclear energy (including its nearly unlimited power) and its downsides (such as its inability to become decentralized…
Energy Efficiency - Technologies and Trends
Episode 21 of The Science of Energy
Where is energy commonly being wasted? How does one become a more efficient energy user? This lecture is filled with takeaways to help anyone (from home owner to car driver to CEO) become more energy efficient in a range of sectors and settings: industries, transportation, residences, and commercial buildings.
Financing the Green Entrepreneurs: Andrew Heintzman
Interview with Andrew Heintzman, the president and co-founder of Investeco, the first Canadian investment company to focus exclusively on investing in environmental sectors. In his recent book, The New Entrepreneurs, Heintzman profiles entrepreneurs who are developing green technology in sectors such as forestry, water, agriculture and energy. He views capitalism…
Terms and Conditions May Apply - Corporations and Your Private Information
Have you ever read the Terms and Conditions and Privacy Policies connected to every website you visit, phone call you make, or app you use? Of course you haven't. But those agreements allow corporations to do things with your personal information you could never even imagine. This film explores the…
Not Without Us - Grassroot Activists Demonstrate at the United Nations' Climate Talks
This documentary follows seven grassroots activists from around the world to the 21st U.N. Climate Talks in Paris. The effects of climate change on their lives reveal what is at stake if a strong agreement to limit carbon emissions is not reached. Yet, the landmark Paris Accords, signed by 192…
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 everything from engineering and economics to biology, chemistry, and geophysics.
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 how energy density affects the transportation of biofuels like petroleum.
Probable and Possible Future Energy Sources
Episode 23 of The Science of Energy
Look ahead to the possible (and probable) advancements in the areas of energy resources. You'll cover the growth of tidal and wave energy, the difficulty of nuclear fusion, the energy potential of earthquakes and supervolcanoes, and giant space arrays of solar panels designed to capture even more solar energy.
Stoichiometry Problems
You extend your study of stoichiometry to consider more complex problems involving volume, molecules, and energy.
