Madam, - John Petch is quite right (February 21st) to draw attention to the considerable energy burden of preparing wood pellets for the stoves now being advocated.
He might also have mentioned the pollution they cause, which includes emission of tars, acids and even the dreaded dioxins.
Perhaps Ministers Roche or Dempsey might care to comment? - Yours, etc,
MAURICE BRYAN, (Conservation adviser), Butterfield Park, Dublin 14.
