National Perspective on Municipalization//Science of Fall Colors

Tom McKinnon and Peter Asmus of Pike Research discuss electrical utility municipalization from a national perspective.  Peter adds an interesting statistic — the photovoltaic industry already has created more jobs than coal mining even though at present it produces much less power.

Shelley Schlender interviews Bill Hoch of Montana State University about why leaves turn colors in the fall.  Bill punches some holes in the conventional wisdom on the topic and notes that the color change is a critical step in the trees retaining important nutrients.

Nitrogen pollution // Electric vehicles

On today’s show we offer two interview features.
Feature #1:

Gulf of Mexico hypoxic zone, caused by excess nutrients, mainly nitrogen from fertilizer

Last week the Environmental Protection Agency published a seminal report about nitrogen, which is an enormous environmental and public health problem that some scientists put on par with the carbon imbalance. Nitrogen is essential for all life, including ours, but excess nitrogen in the environment is turning out to be a predicament of crisis proportions. It kills fish, creates “dead zones” in places like the Gulf of Mexico, contaminates drinking water, and causes human illnesses.
Co-host Susan Moran interviews Dr. Hans Paerl, who has served on the EPA science advisory board and co-authored the report.   He’s a professor of Marine and Environmental Sciences, at the UNC-Chapel Hill Institute of Marine Sciences.

Feature #2:
Our reliance on petroleum-fueled vehicles can be blamed, at least in part for a wide range of problems we face today, from local air pollution to global warming, the balance of payments deficit to political instability on a global scale.  One possible solution is to shift from a reliance on gasoline to the use of electricity for transportation.  Co-host Tom McKinnon interviews John Gartner, a senior analyst at Pike Research in Boulder, to discuss the electric vehicle outlook in the U.S.

Virtual power plants//Wildfires and climate change

Wildfire in the West

Tom McKinnon interviews, via phone, Peter Asmus of Pike Research about Virtual Power Plants.  This emerging information technology may help to integrate more renewable power onto the gird.  And even save money for customers who are willing to turn down their energy demand when the grid is stressed.

At the recent Conference on World Affairs, Susan Moran sat down with Peter Hildeband, the director of the Earth Sciences Directorate at the NASA Goddard Space Flight Center.  He talked about how climate change will impact wildfires in the West.
