>I don't think that they forecasted the decline of coal as drastically as it happened
Coal is starting to come back in the US right now because natural gas prices are starting to rise. For the first time, as of this month, the US is a net exporter of natural gas. Natural gas production increased 70% '05-'14, which caused it to become cheaper than coal. As the US increases exports, the price will make coal more competitive. US power generation facilities often have both NG and coal based turbines allowing them to switch between the two depending on cost. Be careful forecasting the future of energy from short periods of data; the entire energy industry is cyclical going back to when my grandfather was drilling for oil in the 1920s (he went broke).
A shift in production like this would have major effects. For the order in many emerging countries and the state of the economy and labour markets in developed markets. That the EIA doesn't include a potential collapse of a big US industry sector in their forecast is somehow clear, still doesn't mean that it won't happen.
I don't think that they forecasted the decline of coal as drastically as it happened. Oil could be similar, just much bigger.
