In 2008, when Al Gore called for America to get 100 percent from its electricity from renewables in 10 years, he was widely mocked by opponents. Even supporters who understood it was a rhetorical point knew how difficult it would be to achieve.

But suppose the timeframe were stretched out to 2050. Would it really be that crazy? Some models show it’s possible; skeptics say the models are largely unrealistic.

This week, in place of the Energy Gang, we feature a debate between two experts on the issue.

Mark Jacobson, a professor of civil and environmental engineering at Stanford University, faces off against Eric Dennis, a senior fellow at the Center for Industrial Progress.

The two men will debate the following motion: “America can, and should, get 100% of its energy from renewables by 2050.”

This podcast is sponsored by ReneSola, a Tier 1 solar cell and module manufacturer with a decade of experience in the cleantech industry. 

The Energy Gang is produced by The show features weekly discussions between energy futurist Jigar Shah, energy policy expert Katherine Hamilton and Greentech Media Editor Stephen Lacey.
