Why is the UK so far behind in hitting its renewable energy targets? By 2020 the UK must produce 20% of its energy needs through renewable energy, but we are currently falling far short of that. Cornwall is leading the way in the South West but even with planning permission to build a new wind farm it may still be a while before it is actually built. So why are we so far behind and how are these renewable energy targets decided? Guests: Andy Deacon, Head of Regional and Local Delivery at the Energy Saving Trust Tim German, Director of Low Carbon Cornwall

English honey can be difficult to find - so much so, that many supermarkets had sold out of their own brand English honey in early summer. Demand for home produced honey rose by 11 percent last year according to the Honey Association. The problems with supply are of course down to the worldwide decline in the bee population.

For the first time, the public can see a league table rating thousands of public buildings according to their energy efficiency.

Winifred also talks to the shadow energy minister Charles Hendry about the Warmfront scheme.

Most of us know what we need to do to save energy in our home – but just how many of us actually put this knowledge into practice? 64 families from across the UK have being doing just that - as part of a year long social experiment by British Gas to reduce energy consumption.
