Community Power Options Help Reduce CO2

This graph compares the per month cost of electricity to Community Power customers choosing among the various "opt-up" renewables options to the reductions in CO2 these choices afford. For a slight increase in cost, Community Power customers make a substantial impact in helping reduce carbon emissions. In 2025, in a friendly competition among neighboring towns who are members of CPCNH, a larger percentage of Portsmouth residents chose to opt-up than in the other towns.
