Rerun: Could Windows Be A Source of Solar Power? with Professor Stephen Forrest


Office buildings, high rises, and greenhouses are covered in windows. What if we used all that window space to capture solar energy and add to the grid’s renewable energy supply? Listen to University of Michigan engineering professor Steven Forrest explain how a change in the semiconducors used in solar panels could allow us to transform windows into power sources — without sacrificing light and transparency.

Using Solar Energy to Power Large Scale Compost with Chris Seney

In an attempt to reduce methane emissions, California’s SB 1383 has mandated municipalities dramatically increase the amount of organic waste they compost. But responsibly composting at such a large scale takes energy. We spoke to Chris Seney of Republic Services about how their first of its kind solar powered compost facility in Chula Vista, California, could provide a carbon emissions free way to power composting’s expansion.
