Well Dave that's a good question and one I think deserves it's own thread.
Probably the biggest factor is cheap oil and later gas and what was supposed to be cheap electric. There's many reasons really, anthracite production in NEPA topped out in the 20's if my memory serves me correctly. After that it had a steady decline into the 50's and 60's. After that in the Wyoming Valley there was two significant occurrences that put the final nails in the coffin....
In 1959 they had the Knox Mine Disaster, they mined under the Susquehanna river and got a little too close. The river caved the mine in and it flooded the mine. Trouble is that all those mines were interconnected so they all got flooded that were below the water table. They were pumping water out of those mines prior to that but trying to keep up with what was essentially a tidal wave of water was fruitless. If you Google Knox Mine Disaster you can find a lot more info. Here's a pic:
At that point many homes had already started to use other sources of fuel anyway. It was not much more expensive and obviously a lot more convenient. Another thing to point out is coal fired furnaces are not cheap, generally they are 1/3 more than a oil or gas counterpart.
In 1972 Hurricane Agnes hit the Wyoming Valley which flooded many thousands of home if not hundreds of thousands of homes. Most got grants and replaced with either oil or electric heat if they had coal at that point. I believe the nuclear power plant in Berwick was started at that time which was supposed to provide dirt cheap electric which never materialized. Then in the 80's and 90's you had cheap natural gas....
At some point in time there was always an alternative source of fuel that although not cheaper than coal was nearly as cheap... people like convenience so they opted for the easy heat. Kind of hard to blame them considering it wasn't significantly more. Even recently as 3 or 4 years ago oil was nearly as competitive as coal as far as price so why burn coal when you can just turn the dial....
There are a lot of people that use it and have used it for many years, most are in the rural areas. The gas for them was not an option since they couldn't get on a line, oil is more expensive because of delivery costs, additionally many used hand -fired stoves. In many of the very rural areas if the electricity goes out it can be out for days...
The amount using it will probably change now, you're not going to see cheap energy prices like you have in the past.... Unfortunately one of the biggest problems facing anthracite production in the Wyoming Valley is a source. As I mentioned previously all the mines are flooded, on top of that a vast majority of the coal is located below houses, towns etc. It's a fairly built up area with most of the land used for other purposes. This brings to mind a funny story my uncle had told me, he said you could hear them working in the mines while sitting in a girlfriend's living room. That is not going to happen today.
As far as the newspapers they do run a few articles now and then, more recently. Many consumers are switching to coal. Shortly after Katrina hit and the s*** hit the fan there was a tremendous surge in coal sales. I was delivering coal to customers that did not even have anything to burn it in, some didn't even get there stoves installed until a month ago...
Anyhow that's the short version.
