One Planet (Environment)

This week the usual edition of One Planet is replaced by a special programme in our Climate Connection series. We ask ' Is big energy stupid?' . Are there better ways to generate electricity than with conventional power stations, or are we better off finding ways of making conventional generation more efficient? The programme was recorded in south India and is presented by Gareth Mitchell.
