Green Tip of the Month: Conserving Electricity
How you can conserve
On campus, use revolving doors, set window air conditioners to 78ºF, turn lights off in unoccupied rooms and shut the sash on exhaust hoods. At home, save money and reduce consumption by setting thermostats to 78ºF, keeping curtains and blinds closed on hot days, washing clothes in cold water and line drying, if possible, and unplugging appliances, electronics and chargers when they are not in use.
How Rockefeller conserves
The university has decreased electricity consumption by about 600,000 kilowatt hours (kWh) from FY11 to FY12. The bulk of this savings was realized by reducing the speed of large motors in the Power House chiller plant and by recirculating the air in administrative buildings. In addition, Lab Safety’s Shut the Sash program offsets nearly 8,000 kWh per day.
How NYC conserves
The city’s Green Codes Task Force has proposed energy saving laws for new and renovated buildings, requiring improvements such as increased lighting efficiency, “cool” roof coatings and loosening restrictions on external insulation and solar rooftop installations. These policies will help NYC to realize its goal of a 30% reduction in greenhouse gas emissions, attributed mostly to power consumption, by 2030.

The United States consumed nearly 3.856 trillion kWh of electricity in 2011, second only to China.
