Wasted energy?

Passing the Scottish Government building at Victoria Quay on Thursday night I noticed it was fully illuminated in the colours of the rainbow for no particular purpose. It seems Green influence on government is able to tax middle income professionals more than the rest of the UK but cannot stop pointless wasting of electricity. Was this the first thing the SNP could think of to squander their newly claimed riches on?
