Renewable Energy: Solar Marquee
NMSU Professor Thomas Jenkins shows how solar energy can be used to power small stand-alone signs such as the marquee that displays the bus schedule and runs announcements on the NMSU campus. Because the cost and energy savings is significant, an increasing number of solar powered signs are showing up in places like interstates, construction sites, school zones and crosswalks.
