Its size and large number of visitors makes the castle the largest consumer of energy managed by Historic Environment Scotland, the public body tasked with investigating, caring for and promoting Scotland's historic environment.

Despite the increasing numbers of tourists, it has been able to reduce energy consumption by 29% and carbon emissions by 31% since 2008.
