Monte: Yes, apples-to-apples (or, in this case, baseloaded coal to baseloaded combined cycle gas), yes, NG emits half (or less) the CO2 as coal and essentially none of the mercury and acid rain.
New combustion plants are almost entirely gas-fired because they can “follow the wind” (and sun) and vary to meet load demands which coal can’t. Old coal plants are being decommissioned because to renew their 40- and 50-year licenses, they’d be subject to BACT Best Available Control Technology on their emissions to reduce particulates, acid fumes, SOx, NOx, etc. That’s so many millions of retrofits (all on an old plant) that many have opted to not seek license renewal.
And I agree with everyone saying to not throw things away too soon. A new Prius gets 53 mpg, woo-hoo!, but a 1994 Corolla might still be getting 36 mpg which isn’t bad and doesn’t represent all the new resources and energy to build a new car. New cars cost more to purchase than the fuel you could ever put into them.
Best transportation option: Live near work and school so you can walk there.
Next best: be close enough that you can usually take a bicycle.
Best after that: get a small, fuel-efficient, reliable car and use it for 20 years. Borrow or rent a truck those 5 days of the year that you actually need one.
Note that living cheaply is also living more lightly on the land/planet. And the cheaper you live, the less you have to work and the more time you have to hike.
