Today on Volts: for years, I've wanted to do a podcast on indoor air quality, and I finally found the perfect guest! Dr. Lagoudas & I discuss indoor air pollutants, the policies and technologies that can control them, and the growing need to frame indoor air quality as a basic human right.

What's the deal with indoor air quality?
From CO2 monitors to better building codes, Dr. Georgia Lagoudas outlines how to clean up the spaces where we spend 90% of our lives.

5. Solar modules now cost 8.9 US cents per Watt (higher in US, India due to trade barriers). Solar panels are cheaper than ordinary fencing materials. For rooftop installs, non-module cost is still $0.50-3.00 per Watt, so further module price declines make little difference.

Deep dive into the surge in US pedestrian deaths: "It’s not that more pedestrians are getting hit by vehicles; it’s that the ones that are getting hit are more likely to die." "[That] seems like fairly strong evidence for the theory that the rise in large SUVs is behind the uptick in ped deaths."

I'm happy to share a paper in Science Advances that makes the case for a weak land carbon sink, drawing upon JPL and Chloris biomass time series. To close the budget with a net land sink of 0.8 Pg C/y from 2000-2019, we propose increases in the ocean sink and decreases in fossil fuel emissions.
