The UNM Residence Hall Association is working with the Public Service Company of New Mexico to observe "Earth Hour" on Saturday, March 23, from 8:30 p.m. to 9:30 p.m. The Residence Hall Association is asking students who live on campus to turn off all of their electrical appliances for one hour on Saturday evening.

Earth Hour is a national initiative that was started by the World Wildlife Fund. PNM is asking students who observe "Earth Hour" to visit their facebook page and leave messages about how they are spending the hour without power.
