Rachel Bilson has joined up with a whole bunch of other celebrities to get Americans drying clothes on the line — and saving cash and energy at the same time. The campaign comes from Hills, an iconic Australian brand of clothes lines.

According to their release, the use of clothes lines and drying racks in the U.S. has declined steadily since the 1950s as adoption of appliances went mainstream. This has led to the drier becoming the the largest energy sucker in American home next to the refrigerator.

Other celebrities lending their support include Matt Rhys, Olivia Newton-John, Kimberly Joseph, Dannii Minogue, Amanda Detmer, Radha Mitchell, and Melissa George. Said Lost’s Kimberly Joseph, “I grew up in Australia helping Mum hang washing out to dry on the Hills Hoist (and going for the odd swing as well)…nothing like the smell of sun dried t-shirts and linen. With great weather being the #1 draw card here in Los Angeles, clothes dryers should be a thing of the past. Bring on the Hills Hoist, I say!!”

Spring is here! Get your clothes outside!
