"Burning wood pellets releases as much or even more carbon dioxide per unit of energy as burning coal"

"Among the many challenges of burning wood, there are three primary issues of concern. First, burning trees results in more carbon dioxide emission for a unit of energy output (e.g., BTUs). In fact, some smokestack emission tests show burning wood results in carbon emissions 2.5 times higher than natural gas and 30 percent higher than coal. Second, harvesting trees for fuel leads to more carbon release than if they remained in the forests to grow or, if they are dead, recycle carbon into the soil. Thirdly, there is a question of delay relating to the time-lag as new trees take time to establish and grow large enough to capture the capacity lost through harvesting. If you invest some time reading and learning more about burning wood, this is only the beginning of concerns; others relate to the reflective capacity of black carbon and other harmful gases released in biomass combustion."

It's not ridiculous, it's just how it is. Using wood as a large-scale, long term replacement for heating energy across the New England region would just be worse for the environment in the long-term when compared to existing alternatives including natural gas, coal, and nuclear power.

Wow, I was giving you the benefit of doubt that you were talking about particulates, not CO2.
Wood, and I was originally speaking of wood stoves, (although pellets are still better than coal) is CO2 neutral. Trees grow, die, decompose, new trees grow.
Where fossil fuels are carbon emitters, so sure if you only measure the burn, and ignore everything in the supply chain, wood is worse, but you have to ignore everything prior it getting to your house.
It won't be large scale, as people in dense suburbs and cities won't be burning wood, but rural people and less dense suburbs can be part of the solution.
Anybody that lives "in the woods" on about 1.5 acres or more will likely have enough dead trees to heat thier house for years.
That and power companies and other home owners take down dead/dying trees and either leave it to rot or someone can go grab it for free.
