In addition, energy savings for freezers and refrigerators can be realized when purchasing other instruments and equipment.
Centrifuges
Centrifuges can consume a great deal of energy. The rotor itself requires a lot of energy, as well as any cooling functions that the centrifuge might have. Models that have energy-efficient operating modes and low-friction rotors may be purchased. Check for centrifuges that have wind-shielded rotors to reduce friction and carbon fiber rotors that have faster acceleration and deceleration rates and shorter run times. Carbon fiber is also more chemically resistant than aluminum or other metals and has a longer life. Some centrifuges now have vacuum features that further reduce air resistance and friction. Busy labs that process many specimens every day can save energy and money by purchasing larger centrifuges that require fewer runs. For centrifuges with cooling functions - some newer models have automatic shut-off features when the centrifuge lid is opened.
Incubators
Instead of using incubators that have a heat feature to decontaminate, the use of a chemical system such as a vapor hydrogen peroxide method may cut down on energy usage. Checking to be sure closures and gaskets are intact can help with energy efficiency as well.
Other Lab Equipment
One example of a resource worth exploring (listing energy-efficient or green [environmentally friendly] equipment) is

6 In addition, several manufacturers emphasize energy efficiency or green technologies, so performing research before buying new instruments is quite important (the recommendation of specific brands is not allowed). Fume hoods are a particular case, and they will be covered on the next page.
