In recognition of its drive to go green, the Town of New Castle was recently named the first small community the state and first community in Westchester County to be designated a Clean Energy Community by the New York State Energy Research and Development Authority. New Castle received the designation for completing four of 10 high-impact clean energy actions identified by NYSERDA as part of the Clean Energy Communities initiative: Implemented Community Choice Aggregation, where residents and businesses in the town pool their demand for energy and take part in a bulk purchase of 100 percent clean, renewable electricity.
