There's nothing like having to pay your own electricity bill to encourage economy in the use of lighting. Conversely it takes a body like Bristol City Council to really waste energy, since whatever it costs comes out of our pockets, not their own.
Here near Temple Meads the spotlights are blaring around 7 pm when dusk is at about 10 pm at this time of year. Likewise around the centre and the glass arcade at St Nick's market (below). Now supposing you had some spotlights on your home coming on at 7 pm even at the height of summer, wouldn't it cross your mind that you were wasting energy, and money, and needlessly adding to carbon emissions? Yes, of course it would, and you'd soon do something about it.
But what if you work for Bristol City Council? Do you notice? Do you care? Is it your responsibility? Probably the answer is 'no' to at least one of those questions, because as we see nothing gets done about even such a simple matter. That's the nature of the beast. The Council is impersonal and irresponsible. Corporate responsibility means no one takes individual responsibility. Yet so many people want to give more corporate 'responsibility' to the same body to address environmental issues. People, they can't even be bothered to switch the bloody lights off!
