This week, we're coming to you live from the SXSW Eco conference in Austin, Texas. 

First up: Revolution now. The Department of Energy released its latest progress report onsolar wind, batteries and LEDs. Even for those who follow the space, the data is pretty remarkable. How optimistic should recent progress make us?

Then, America’s post-coal future. Can we leave coal behind without leaving people behind?

Finally, the federal government is throwing its weight behind autonomous vehicles. Are we entering the era of driverless cars?

A warning about the audio: a problem with the feed from the mixer made the audio unusable. So we had to get creative audio from a recorder near the PA system in the room. We apologize for the wonky sound!
