Most estimates are that the world doesnt run out of fossil fuels, it runs out of place to put the CO2 produced by burning them. A few environmental groups have come to conclusion that just burning the current proven and near term potential fossil reserves, that the CO2 level in the atmosphere gets high enough where the high end of the predictions for global warming are likely.

The High End
The high end of AGW is methane turnover.
Look at the charts on today's warming vs. PETM,
but that is a thousand years from now or so, and people only care about now.Comment

The payback period for bloom energy boxes is between 20 and 25 years without any subsidy.
Without a combination of federal tax credits and state incentives, no one will be willing to spend money on this technology. Even after the subsidies, the payback period is close to 10 years.
The only positive aspect is natural gas prices are going down and it provides some attraction.
However the fuel cells need replacement after a certain number of years and if you perform a Life Cycle Cost Analysis, it probably doesnt make any sense to buy one except for PR purposes.
There are instances where it might make sense financially - when you use biogas ( like ebay does for its data centers ) but it is an exception rather than the norm.Comment
