This collection of photos from the NASA Climate website features images related to global change. Not all images show change caused directly by climate change and energy use, and descriptive captions indicate causes for change in most of the images.

This video segment highlights how the U.S. military is the single largest user of energy in the nation, but it is also trying to reduce its carbon bootprint. Scenes taped at Fort Irwin and Camp Pendleton show the Army and Marines experimenting with wind and solar in order to reduce the number of fuel convoys that are vulnerable to attack.

This video highlights the benefits of electric vehicles, including improved fuel efficiency, reduced emissions, and lower maintenance costs.

In this activity students trace the sources of their electricity, heating and cooling, and other components of their energy use though the use of their family's utility bills and information from utility and government websites.

This video reviews how photovoltaic (PV) cells work, noting that technological innovations are decreasing costs and allowing PV use to expand.

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

In this role-play activity, students take the roles of various important players in the climate change policy debate including politicians, scientists, environmentalists, and industry representatives. Working in these roles, students must take a position, debate with others, and then vote on legislation designed to reduce greenhouse gas emissions in the United States. Can be used in a variety of courses including writing and rhetoric, and social sciences.

This engaging video focuses on national and global wind energy potential by specifically highlighting Texas' role as wind energy leader and energy efficiency efforts in Houston, Texas.

This video is one of a series from the Switch Energy project. It presents pros and cons of hydraulic fracturing, or fracking. In this video, new fracking technologies are presented as more economical and environmentally safe.

An activity focusing on black carbon. This activity explores the impacts of the use of wood, dung, and charcoal for fuel, all which generate black carbon, in developing countries.
