Carl and Richard continue the Geek Out series on alternative energy with wind power. The conversation starts with the admission that as much as has been done with wind power so far, it's just a tiny drop in the bucket of total power consumption - less than 1% of US power comes from wind. Then the boys dig into the different types of wind power generation, the challenges that the power grid has incorporating wind power into the grid, and the kinds of problems that home owners have with wind power also. Wind has potential, but also problems. But long term it's part of the solution.
