There's been a bit of discussion recently around the issue of shopping mall lights staying on well after opening hours. Although it's not happening at the moment, there's been a fair amount of load-shedding across the country in the last year or two, due to electricity shortages; and I think there's certainly a case to be made for more responsible use of lighting by shopping malls and the like. Even though I always think the lights at Canal Walk are terribly pretty, that's really not enough reason to keep all those lights burning every night, is it? (This photo doesn't even begin to show the extent of the lighting at Canal Walk, by the way.)

A number of companies - such as the Virgin Active chain of gyms - have taken definite steps to lower their electricity consumption; maybe it's time that others followed suit.
