Geothermal heating is a low-cost, clean source of energy that preserves air quality by providing no nitrogen oxides, no emission of particulates, no sulfur oxide
, and no carbon dioxide.
But the biggest concern, in Carney's opinion, is the presence in flue gas of nitrogen and sulfur oxides

According to Young, meeting that power demand results not only in the generation of millions of tons of carbon dioxide (a greenhouse gas), but also in the emission of thousands of tons of nitrogen oxides and sulfur oxides
- the principal precursors of acid rain.
