Just in time for New Year’s resolutions, today’s global warming podcast focuses on residential energy use. It’s the last in a four-part, year-end series on greenhouse gas emissions.

So far, we’ve talked about electricity generation (Thursday), transportation (Friday) and building construction (Monday). Today, we ask Neely Crane-Smith, coordinator for the Minnesota Energy Challenge, about changes people made in their homes in 2007 to reduce carbon emissions.
