For more than 1,300 years the site of Gloucester Cathedral, in the south west of England, has been a place of continuous worship. Rich in history, it is home to the tomb of King Edward II, who died in 1327. Now, it has become one of the oldest cathedrals in the world to have solar panels.
"The Church of England… has a campaign which is called Shrinking the Footprint, and it's a very ambitious campaign to reduce carbon emissions throughout the Church by 80 percent by 2050," Anne Cranston, Project Pilgrim manager at Gloucester Cathedral, told CNBC in a phone interview.
Commenting on the Shrinking the Footprint project, the Bishop of London, Richard Chartres, has previously said that the Church is "committed to mitigate the effects of climate change which will fall disproportionately on the poor and vulnerable in the world."
Solar power is becoming an increasingly important part of the planet's energy mix. In the U.S., for example, data from GTM Research and the Solar Energy Industries Association has shown that the solar industry there installed 7,286 megawatts of solar power in 2015, an increase of over 1,000 megawatts of solar photovoltaic installations compared to 2014.
Back in Gloucester, Cranston explained why solar was seen as a viable way of making the Cathedral a beacon for clean energy.
