§ Mr. Llew SmithTo ask the Prime Minister what assessment he has made of the advantages of using photovoltaic solar energy to power the lights on the Christmas tree at Downing Street; and what representations he has received on this subject. [22060]
§ The Prime Minister[holding answer 22 December 1997]: I have not made an assessment, nor am I aware of having received any representations on this subject. However, as my hon. Friend may be aware, photovoltaics are at their least effective during the short winter days and power is needed at night when the panels would not work.
