Despite the hype about the shale gas revolution, the extraction cost of (onshore) conventional gas remains below that of shale gas.

Even so, the shale revolution across the Atlantic has been felt in diverse ways.

The shale energy revolution that started in the US is thus causing sweeping changes worldwide.

The big news in energy these days is the revolution in technology for tapping shale gas.

Even the much heralded shale gas revolution is a lot of hype 160 similar to the gold rushes and stock bubbles of the past. Shale gas wells deplete far more rapidly than conventional fields do.

Tar Sands and Shale.

The question today is whether a new upsurge of investment will come to our rescue. Optimists point to the shale energy revolution in the US.

Shale Gas to the Rescue?

The Shale Revolution s Global Footprint

Exploration is proceeding only hesitantly and shale gas production has not even started, prompting many observers to lament that Europe is about to miss the next energy revolution.

Whereas extraction of America s extensive reserves of natural gas was previously thought to be unfeasible, technologies such as hydraulic fracturing ( fracking ) have ushered in a shale gas revolution.

The US economy s road to recovery is being built on the shale gas revolution, a revived manufacturing sector, and a decline in the US budget deficit in GDP terms.

The Bowland Shale, which lies beneath Lancashire and Yorkshire, contains 50 more gas than the combined reserves of two of the largest fields in the United States, the Barnett Shale and the Marcellus Shale.

And shale is not quite completely competent rock.

The United Kingdom has been reluctant to join the hydraulic fracturing (or fracking) revolution. Yet tapping the Bowland Shale could reignite the UK economy and deliver huge cuts in CO2 emissions.

To my right is sheer shale. It's coming off.

You hit rock and then those layers of shale.

Even more significant, however, are the differences in energy costs, which are now up to 50 lower in the US a gap that is likely to widen further as America s shale gas revolution continues.

Two thirds of the world's shale is in the US.

Of course, no one should think that America s shale gas revolution (which has brought it to the brink of energy self sufficiency) means that its Bahrain based Fifth Fleet will lift anchor any time soon.

Shale gas wells deplete far more rapidly than conventional fields do.

In Europe, shale energy resources have largely remained in the ground.

longwall mining, fracking, tar sands, tar shale, deep ocean Arctic drilling.

America s shale gas industry grew by 45 annually from 2005 to 2010, and the share of shale gas in America s overall gas production grew from 4 to 24 .

In principle, Mexico s economy should be benefiting from the same shale gas revolution that is providing a huge boost to the US, where natural gas prices are now less than one quarter of what Europeans pay.

Nor are earlier trade balances about to reemerge. America s trade position will be strengthened by the shale gas revolution, which promises energy self sufficiency, and by increases in productivity that auger further re shoring of manufacturing production.

Our revolution is a people's revolution

Another major revolution the communications revolution.

In 2013, it was announced that Japan would be importing shale natural gas.

That's really my job at Pennsylvania Shale, you know, to put out fires.

Our revolution is a revolution for freedom

Revolution.

Revolution.

Revolution?

The real revolution is the revolution of values.

Our revolution is a popular, peaceful, national revolution.

Indeed, the Glorious Revolution enabled a revolution in finance.

The revolution this revolution is much bigger than that.

The Orange Revolution in Ukraine, the Lemon Revolution in Kirghiztan the Grape Revolution in Moldova the Apricot Revolution in Armenia they are all fruits that have been used to name a revolution.

In particular, the shockwaves triggered by the shale energy revolution unleashed in the United States are reverberating globally. With the advent of hydraulic fracturing, or fracking, US oil production has risen by 30 , and gas production by 25 , in just five years.

PRAGUE In late June, the British Geological Survey announced the world s largest shale gas field.
