The Nuclear Obsession -
Time for an Energy Alternative?
Increasingly, countries throughout the world are making practical use of wind and solar power, tidal energy, and new ways of burning fossil fuels. They're saving a fortune. But Britain has fallen far behind - jolted out of its complacency only by the Government's plans to privatise electricity, and by what has been revealed about the true costs of nuclear power.
Public Eye looks at the legacy of our nuclear obsession - is it too late for a clean start?
Presented by Peter Taylor with Mike Embley. Producer PHIL CRAIG

There's a new look to
Gardeners' World for the new decade. This has been designated 'Gardening for
Beginners Year', so there are regular reports aimed at those first-time gardeners.
'Barnsdale Diary' provides topical tips and information and, with the help of the people of Llandderfel,
Gwynedd, the programme looks at how to revive flagging Christmas houseplants. And there's a chance to meet the 'green stringers', the programme's amateur correspondents.
With Geoff Hamilton ,
Anne Swithinbank , Pippa Greenwood and Nigel Colbom.

"Everybody tn the world, so they say, has a double." (Graham Greene, The Human Factor)

For 25 years the author Graham Greene found himself the victim of a bizarre masquerade. A man calling himself Graham Greene opened hotels in Jamaica, courted high society in the South of France and was entertained in India by tea planters convinced that he was the real author. The other Graham Greene has left few traces behind. But is 'the other' perhaps a decoy, invented by the secretive Greene to confuse and deceive his chosen biographer Norman Sherry? Greene joins Arena on the trait of his Doppelganger.
