Los Angeles Metropolis Faculty Goes Off the GridLos Angeles City Faculty (LACC) began a bold plan in 2006 to take all 9 of their campuses off the grid. By putting in sufficient PV panels to generate one megawatt of power per day, LACC hopes to guide the way in the use of sustainable power on faculty campuses. This system of community faculty campuses serves greater than 185,000 college students within the larger Los Angeles space. They also have plans to offer sustainability and green building courses to their curriculum. LACC is growing fast and has plans to build greater than 40 new buildings that meet or exceed the standards set by the Management in Energy and Environmental Design [supply: treehugger.com].
