facilities. taking on one solar project is much more reasonable at the moment. stonehill college is currently building one of the nation s largest college campus solar fields. it is a 2.7 megawatt field that will contain 9,000 solar panels. the solar field is expected to save about $185,000 a year on energy costs and account for 20 of the
these traffic control lights which previously used incandescent lights with watts ranging from 20 to 100 w have gradually been replaced with light emitting diodes (leds). these leds which reduced the power consumption of the traffic lights to a very few watts also created another problem, which is drivers' disability of seeing or interpreting these lights as they approach to the traffic lights on nominal speed.
