This video provides an overview of the research of the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) on converting biomass to liquid fuels.

This is a short NASA video on the water cycle. The video shows the importance of the water cycle to nearly every natural process on Earth and illustrates how tightly coupled the water cycle is to climate.

This video segment describes climate data collection from Greenland ice cores that indicate Earth's climate can change abruptly over a single decade rather than over thousands of years. The narrator describes how Earth has undergone dramatic climate shifts in relatively short spans of time prior to 8000 years ago. The video and accompanying essay provide explanations of the differences between weather and climate and how the climate itself had been unstable in the past, with wide variations in temperature occurring over decadal timescales.

This video from the U.S. National Academies summarizes the energy challenges the United States faces, including the technological challenges, and the need for changes in consumption and in energy policy.

This detailed animated map shows global weather and climate events from the beginning of 2009 to the present. As the animation plays, specific events are highlighted to provide context and details for the viewer.

In this EarthLabs activity, learners explore the concepts of coral bleaching, bleaching hot spots and degree-heating weeks. Using data products from NOAA's Coral Reef Watch, students identify bleaching hot spots and degree-heating weeks around the globe as well as in the Florida Keys' Sombrero Reef to determine the impact higher-than-normal sea surface temperatures have on coral reefs.

This video focuses on the conifer forest in Alaska to explore the carbon cycle and how the forest responds to rising atmospheric carbon dioxide. Topics addressed in the video include wildfires, reflectivity, and the role of permafrost in the global carbon cycle.

This introductory video covers the basic facts about how to keep residential and commercial roofs cool and why it is important to reducing the heat island effect and conserving energy.

This video provides a simple introduction to wind turbines and how they generate electricity.

This introductory video describes the basic principles of residential geothermal heat pumps.
