The utilisation of any source of energy depends on government action. It is a matter of deciding on what, and on whom, that taxpayers' money is to be spent, and why. A Government headed by the man who not only turned up to the Durham Miners' Gala, but who told it that he was going to reopen the pits, is the only Government that you can really trust on these matters.
