FoE’s league table ranks 32 cabinet members according to the number of solar installations in their constituency. It comes ahead of Saturday, the longest and lightest day of the year – potentially the best day for solar panels – and as Friends of the Earth urges all MPs to get behind its new Schools Run on Sun campaign (supported by players of the People’s Postcode Lottery), which aims to make it easier for schools to run on solar power. Andrew Lansley rules the school with 3108 solar installations in Cambridgeshire South, and David Cameron earns House points in second place, with 2143 installations in Witney. Justine Greening meanwhile ranks last with just 114 solar installations in her constituency, Putney. The Energy Secretary Ed Davey himself puts on a disappointing performance in third from last place, with just 252 installations in Kingston & Surbiton.
