Bullfrog sources power exclusively from generators who meet or exceed the federal government's Environmental Choice Program EcoLogoM standard for renewable electricity. Our power comes from clean, emission-free sources like wind power and low-impact water power instead of carbon-intensive sources like coal.
Conventional electricity production is among the largest industrial sources of carbon dioxide, a primary greenhouse gas that is linked to climate change. Electricity production is also a major source of pollutants including nitric oxide, sulphur dioxide, mercury and particulates that contribute to poor air quality and smog conditions.
