Can We Meet Our Energy Needs with Solar?

Theoretically, we could get all of our energy from the sun. But is it realistically feasible? And if so, what are the technical, economic and political barriers to reaching that lofty goal? In this podcast, we'll look at the challenges and implications of such a heavy reliance on solar.

First, we'll take a brief tour of the new air-cooled solar thermal tower in the Northern German town of Jülich.

Then, Michael Webber of the University of Texas at Austin describes the complicated relationship between energy (including solar energy) and water.

Finally, Ken Zweibel of the George Washington University Solar Institute talks about the possibility of powering the entire U.S. with solar.

Inside Renewable Energy is a weekly audio news program featuring stories and interviews on all the latest developments in the renewable energy industries.
