Princeton's goal is to reduce carbon emissions to 1990 levels by 2020 through conservation, energy-saving technologies, renewable energy generation and behavior change. This exhibit featured Princeton's energy saving initiatives on campus including new innovative and efficient lighting sites, energy efficient instruments used on campus, and campus as lab research on the importance of urban microclimate as well as wind power research.
Various light bulbs were on display to demonstrate the difference between old and new technology in light bulbs. Featured light bulbs included 35 Watts Halogen, 10 Watts LED, 60 Watts Incandescent, 24 Watts CFL, 12.5 Watts LED, 90 Watts Halogen, and 18 Watts LED.
An eth sensor, one of the instruments on display, records relative humidity and temperature; the shield protects the instrument from direct radiation which can bias temperature measurements.
The Infrared (IR) Camera on display measures longwave radiation from surfaces and produces temperature maps of the environment.
Vampire power is the energy drawn by electronics even when turned off. Annually this "wasted" power accounts for more than 100 billion kWh of U.S. electricity consumption and more than $10 billion. A surge protector can cut down on vampire power if turned off when electronics are not in use. Plus, they protect your electronics in case of a power surge or lightning storm!
