Forget about carbon emissions, there’s enough hot air blown out over climate change to heat every home in Sheffield. But for all the blather and political posturing no one actually took any notice of the UK's first Energy Saving Day, which ended with no noticeable reduction in the nation's electricity usage.

E-Day sounds like a great idea, except for the fact that in order to save energy its organisers forgot to tell anyone about it.

E-Day's Dr Matt Prescott explained: "I am afraid that E-Day did not achieve the scale of public awareness or participation needed to have a measurable effect".

Organisers wanted people to switch off any electrical devices they didn’t need over a period of 24 hours, with the National Grid monitoring consumption.

But electricity usage was almost exactly what would have been expected without E-Day. In fact, it was a little higher.

Guess what the E-Day greenies used as an excuse. You can’t make this stuff up, but the organisers blamed… the weather!

“E-Day did not succeed in cutting the UK's electricity demand. The drop in temperature between Wed 27 Feb and Thurs 28 Feb days probably caused this, as a result of more lights and heating being left on than were originally predicted,” reads a statement on the E-Day website.

The Grid's final figures showed national electricity consumption for the 24 hours (from 6pm Wednesday to 6pm Thursday) was 0.1% above the "business-as-usual" projection.

Apparently the E-Day concept began life as a planned BBC programme “Planet Relief”, which featured a significant comedy element.

Good to see that E-Day continues the hilarious theme. Better luck next year, guys, but try to get the message out first.
