TorBayguy, wood vs. gas isn't that simple.  Wood stoves release particulates in the smoke which causes health problems and, on a large scale, can increase absorption of sunlight.
For GHGs the wood is recycling carbon that was recently in the atmosphere so there is no net increase.  Natural gas is releasing carbon that has been locked underground for millions of years so there is a net increase.
Alas there is no free lunch.
