This video features the story of a multi-generational family-run dairy business in Oregon that aspires for sustainability while serving a local market, conserving energy, and reducing greenhouse gas emissions by burning waste from its dairy cows.

This short video reviews how nations and individuals on Earth can work together to reduce the emission of CO2. It discusses strategies to reduce greenhouse gas emissions (energy conservation, renewable energies, change in energy use) and the role that government can play in this process.

This animated slideshow introduces biodiesel as a fuel alternative. With concern about the use of petroleum-based fuels at an all-time high, biodiesel is experiencing a popularity surge. And algaeâotherwise known to some as pond scumâ are grabbing headlines as the next potential biodiesel superstar. But how and why do algae make oil? And why do they make so much of it? In this audio slide show, U.C. Berkeley's Kris Niyogi describes the process and its potential.

This video features three faculty from the University of Colorado, Boulder (Beth Osnes, Max Boykoff and James White) and CU students taking action with others to help mitigate climate change at a local level - making personal decisions about energy use and family size, educating the university community about actions that individuals can take, and developing materials to build sustainable housing.

This short video makes the case that rapid climate change affects the whole planet, but individuals can make a difference and make their carbon footprint smaller. Common suggestions are identified for young children to consciously consider what they can do.

This is a laboratory activity in which students will compare the amount of carbon dioxide in four different sources of gas and determine the carbon dioxide contribution from automobiles. They test ambient air, human exhalation, automobile exhaust, and nearly pure carbon dioxide from a vinegar/baking soda mixture.

This video addresses the importance of efficiency in providing power to an increasingly large global population.

This video describes how field research -- in this case, making water measurements in rugged mountain locations -- helps us to understand the complex relationships among changing climate, populations, and water usage.

Students calculate the cost of the energy used to operate a common three-bulb light fixture. They then compare the costs and amount of CO2 produced for similar incandescent and compact fluorescent light bulbs. Students also do a short laboratory activity to visualize why two bulbs, which give off the same amount of light, use different amounts of electrical energy.

This video is essentially an infomercial about electric cars - components, challenges, benefits - narrated by Antonio Neves of the.News and featuring various members of the auto industry.
