Right below your feet is a source of renewable energy that is largely untapped. It heats groundwater by conduction and convection as it travels toward the surface of the earth. Lawrence Livermore National Lab scientists Carol Bruton and John Ziagos explain how geothermal energy can be used to generate electricity or heat buildings.

Creating a star on Earth is the goal of the National Ignition Facility (NIF), the world's largest laser. When completed in 2009, NIF will focus 192 giant laser beams on a BB-sized target filled with hydrogen fuel - fusing, or igniting, the hydrogen atoms' nuclei. This is the same fusion energy process that provides the life-giving energy from the sun. NIF Director, Ed Moses, describes how NIF works and its potential to provide a limitless supply of clean, safe energy.

Most scientists agree that man-made carbon dioxide released into the atmosphere is the main cause of climate change. So why not store it somewhere instead of releasing it to the air? Great idea and scientists have been thinking about this for some time. Lawrence Livermore National Laboratory scientist Julio Friedmann discusses carbon capture and storage (CCS), and how it might be used.

The physical and chemical properties of hydrogen make its use superior to fossil fuels. Producible virtually anywhere from using electricity, it is a simple, non-toxic molecule that can generate electricity or power vehicles cleanly, efficiently, and even silently, if we choose. Development of hydrogen automobiles has been hindered, however, because hydrogen is much more difficult to store than gasoline. Gene Berry, Research Scientist at Lawrence Livermore National Laboratory and high school teacher Dean Reese, explore the need for alternatives to gasoline and what role hydrogen might play.

Will we run out of certain forms of energy, such as oil, and what are the replacement options? How does hydrogen fit into the future U.S. energy picture? What is carbon sequestration and why does it matter? What about sustainable energy sources such as solar, wind and geothermal? John Ziagos, Atmospheric, Earth, and Energy Department at Lawrence Livermore National Laboratory, and high school teacher Dean Reese present the latest information on the earth's total energy budget to see what forms of energy we will be harnessing in the future.

Imagine a sphere much smaller than a pea releasing enough energy to supply all of the electricity needs of the United States for a brief moment in time. How could this be possible? At the National Ignition Facility, a huge laser in Livermore, California, scientists and engineers are nearly ready to make this a reality. Edward Moses, the Project Manager at National Ignition Facility, explains how energy can be compressed to extreme power levels to potentially provide for a future of clean energy for our world.
