Transcript:On sweltering summer days in Austin, Texas, most homes have the windows shut and air conditioners pumping. But some people cannot afford to run their AC enough to adequately cool their homes. And if the power goes out in a storm, air conditioners do not work. So some houses can quickly become dangerously hot inside – especially older, drafty homes that allow heat to seep in faster. So the city funds programs to help low-income residents make energy efficiency improvements, like adding insulation or reflective roof coatings, which can help homes stay cooler without using as much AC.
