Even as we here in the good ol’ U S of A are beginning to tear down hydroelectric dams, others are building them to address energy problems. Today’s Wall Street Journal (October 12, 2009, at p.

Georgia, it says, is an exporter of electrical energy, and it is a country “where getting a construction license takes just three months.”
