Church roofs, solar panels and climate change | Letters

The Church of England's Shrinking the Footprint campaign is encouraging dioceses, cathedrals and parishes to reduce energy bills and lower carbon emissions through practical steps, from installing energy-efficient lightbulbs to switching to renewable energy (Blessed be the solar roof installers, Letters, 17 May).

More than 400 churches, church buildings and vicarages already have solar panels installed, with other developments including the first carbon-neutral churches. Other measures adopted have included the installation of ground source heat pumps in some churches.
