Nigel Lawson schreibt in der Daily Mail: The consequences of the shale revolution are difficult to exaggerate. Not just in terms of the economic benefit of a new and abundant source of relatively cheap energy, but in geopolitical terms, too. It has shaken up the old world order — and the global balance of power is being permanently transformed before our eyes. The green lobby, of course, is terrified that, despite the promotion of expensive and heavily subsidised wind power at the heart of the Energy Bill — a subsidy paid to a considerable extent by poor householders through their bills to wealthy landowners with wind turbines — the emergence of large supplies of cheap gas will make this policy unsustainable.
