In this activity, students conduct an energy audit to determine how much carbon dioxide their family is releasing into the atmosphere and then make recommendations for minimizing their family's carbon footprint.

In this video, students explore the work of Jay Keasling, a biologist who is experimenting with ways to produce a cleaner-burning fuel from biological matter using genetically modified microorganisms.

This documentary film takes the viewer on a virtual trip around the world to visit communities in different countries (Asia, Africa, Central America, Australia) taking action on climate change. The documentary weaves together nine inspiring stories, showing that action on climate change is creating jobs, improving lives and turning dreams of a better future into reality.

Students analyze complex real-world problems by specifying qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants. This place-based activity discusses multiple strategies to reduce carbon emissions, and realistic paths to preventing climate change.

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 is one of a series from the Switch Energy project. It reviews the environmental impacts of various energy resources including fossil fuels, nuclear, and renewables. CO2 emissions as a specific environmental impact are discussed.

In this activity, students become familiar with the online Renewable Energy Living Lab interface and access its real-world solar energy data to evaluate the potential for solar generation in various U.S. locations.

Students use long term sea-level rise data set to create models and compare short-term trends to long-term trends. They then determine whether sea-level rise is occurring based on the data.

This Flash animation describes how hybrid-electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools.

In this classroom activity, students analyze regional energy usage data and their own energy bills to gain an understanding of individual consumption, regional uses, costs, and sources of energy.
