Fracking increases extraction temporarily with very rapid well depletion rates. Continued extraction requires drilling more wells. Compare this with oil production from traditional "whale" fields in which a single well can deliver for decades. This vastly increases capital costs and reduces EROEI.
Methane hydrates are yet unproven, and present their own very serious challenges.
In either case, the prospects for global warming and emissions management attack the other side of my statement: cheap abundant fossil fuels. While coal exist to supply needs for (depending on whom you talk to) 100-1000 years, the evidence suggests that the climate and our economy won't tolerate the emissions resulting from its consumption.
Coal-to-liquids infrastructure is very expensive and takes a long time to ramp up.
What are your source(s) for fracking production? Sincerely interested.
