On this edition of Houston Matters, we explore why Texas leads the way in executions, and what it says about us. Also, the energy industry is a key component of Houston's economy. We'll talk with author Michael Leviabout his new book The Power Surge, which calls for a "most of the above" approach to America's energy policy. Plus, an Astrodome update, and a Houston professor challenges her architectural students to redesign neglected areas of the city.
