Environmental Stewardship

What Can You Do to Save Energy and Natural Resources on Campus?


  • Always turn off your lights whenever you leave your room.
  • Utilize natural light whenever possible. Open your blinds.
  • Use only Compact Fluorescent Light (CFL) bulbs in all your lights. They use 75% less energy than incandescent (normal bulbs) and last 10 times longer.
  • Turn off lights in bathrooms, lounges, and other common areas. Tell others to do the same.


  • Turn your computer off when you aren't using it.

Energy and Emissions

Energy Consumption on Campus

Most campus buildings are served by central heating and cooling plants. The boiler plant generates steam from the combustion of natural gas and delivers it throughout campus for heating, domestic hot water, and dehumidification purposes. The chiller plant delivers chilled water throughout campus for air conditioning purposes. In FY2011, the campus consumed 1.6 million therms of natural gas and 22.5 million kilowatt hours of electricity.

Through the City of Grinnell, the college can now collect most standard recyclables as a single stream. The following can now be disposed of collectively in the same recycling bin.

  • Hard Plastic Containers labeled #1 through #7
  • Aluminum and tin cans
  • Glass bottles and containers
