From Liisa O'Neill, Department of Energy, Office of Public Affairs: Who knew leaks could be costing Americans $5 billion every year? And that's not water leaks—it's leaks you can't even see. Typical air duct systems, both residential and commercial, typically lose 25-40 percent of heating and cooling energy, accounting for billions added to utility bills. But what if there was a simple mist that could seal thousands of leaks in 4 to 8 hours,... Read More

Two vehicles -- one black one silver, parked on the pavement and in the sun.
October 17th 2011
Nearly all cars sold in California have air conditioners. Cars painted with reflective coatings stay cooler in the sun and are easier to air condition to a comfortable temperature, according to a recent study by researchers in Berkeley Lab's Environmental Energy Technologies Division. "Solar reflective paints can decrease the ‘soak' temperature of the air in a car that has been parked in the sun. This could improve the vehicle's fuel economy by... Read More
