Dr. Christopher Clack is a mathematician and research scientist for the Cooperative Institute for Research in Environmental Sciences at Colorado University at Boulder.  He joins us to talk about his latest work of building an energy, well more specifically electric, simulator. Dr. Clack discusses how it allows us to seek out the most cost effective approach to rebuild the future energy system in a methodical calculated way. It is a model, so you can investigate almost infinite possibilities and display them for decision makers.
