The big benefit of gas is that it is cheap and indirectly subsidizes economic growth. I do not know if anyone knows how long the resource can last, but I do not think we need to care. All work is done on twenty year timelines and that matches the economic life of just about everything except housing.
Shale gas is also quite often a local resource and is well received.
Many other energy resources are entering the market and will over time displace all fossil fuels. However, at present it will always be the cheapest choice for simple home heating. Even if it were only available for the life of the furnace and water heater it is well worth it.
Transitioning to more costly energy sources will hardly be a problem a couple of decades later although so far that option has never been exercised in the past fifty years and we may well have another fifty to be fat and happy.
US mounts global push for shale gas

Shale gas comes from deep reserves that were thought inaccessible until the advent of new drilling methods.

Shale gas comes from deep reserves that were thought inaccessible until the advent of new drilling methods. But costs still are usually above conventional gas, and some environmentalists worry about pollution in drinking water.
In Europe, shale gas could also reduce reliance on energy heavyweight

"The main reasons for doing it are national security and climate security," David Goldwyn, the State Department's coordinator on international energy affairs, said of the conference.
Eastern Europe in particular, it's really diversity of supply. It's a national security issue," Goldwyn told reporters.
China and , it's both climate security and economic security, because they have large demand for resources and the market is volatile," he said. India
Another potential reason -- the
United States, and to an extent , have an edge in shale gas. Last year, the Canada United States overtook for the first time in decades as the world's top gas producer. Russia
"In this country it's entirely possible, if things continue on trend, that we would have the ability to export gas extracted from shale," Goldwyn said.
energy companies made presentations during the talks, but insisted it was not a "trade conference." US
India's biggest private firm, Reliance Industries, has been eager to pursue shale gas, investing nearly 3.5 billion dollars since April in joint ventures for fields in the

China has been trying to catch up, with the state-owned China National Petroleum Corp reportedly recently setting up a research center for shale gas.
But some environmentalists are not convinced that shale gas is the way to go.
Bentley Johnson, legislative representative at the Washington-based National Wildlife Federation's Public Lands Campaign, said that while gas burned cleaner than other fossil fuels, the effect was less when factoring in the energy expended to extract and transport it.
Even more worrisome, he said, are dangers to drinking water from hydraulic fracturing -- injecting water and chemicals deep underground to bring out gas.
"It makes more sense to invest in truly clean renewable energies such as wind and solar rather than staying on a traditional fossil fuel way of getting our energy," Johnson said.
"As far as the solution to worldwide energy demands in growing economies like
, I don't think it's the answer," he said of shale gas. China
In the documentary "Gasland," which won the Special Jury Prize at this year's Sundance Film Festival, filmmaker Josh Fox showed families in a drilling area whose tap water was even flammable.
Asked about environmentalists' concerns, Goldwyn said they showed the need for regulations -- a "huge part" of the 20-nation discussions.
"If done responsibly, it can be done safely," he said.
The talks included four Asian energy importers --
China, India, Indonesia and Pakistan -- along with eight nations in Russia's vicinity: Armenia, Bulgaria, Estonia, Georgia, Lithuania, Poland, Romania and . Ukraine
Chile, Colombia, Peru and Uruguay came from South America, where energy power Venezuela is a nemesis. The other nations that participated were US Jordan, Morocco and . South Africa
