The Mercer GreenFest is hosted by the Mercer County Sustainability Coalition (MCSC), and is the area's local green fair featuring sustainable local businesses, community organizations, local farms, cooking demonstrations, hands-on workshops, and informational speaker presentations.  It is organized by the MCSC to educate and inform residents about the best of new energy saving technologies, to promote local businesses and organizations, to further arts and showcase what can be accomplished working collaboratively. This year's theme is reduce, reuse, recycle. This event is free and open to the public.
