If you put your kettle on a gas stove, you probably heated three times as much water as you needed with gas that heated the kettle but also sent a lot of its heat around the kettle. The gas you used could have come from lots of places – but if it comes from this new shale gas everyone is talking about, millions of gallons of water were used to allow gas production from the shale rock in addition to the water used drilling the gas wells in the first place.
