With your enrollment in Second Nature, we're able to buy more earth-friendly renewable energy produced from wind and solar power.


We combine your requirement with other Second Nature customers to get the month's total green requirement. Then we make sure we're bringing enough new green energy into our energy pool to meet the total green requirement. This additional green energy displaces electricity that would otherwise come from sources like coal, gas and nuclear. A third party verifies annually that all electricity purchased on behalf of Second Nature participants comes from qualified renewable resources.
