How many power stations does it take to change a lightbulb? Three!

No? OK. How about, how many power stations would the UK not have to build if the entire country switched to LED?

Three!

“How many power stations does it take to change a lightbulb? It’s beyond a joke”

It’s not working well as a joke, is it? Probably because power stations aren’t funny. However, three is still a magic number. Because, using as a guide the exotically named West Burton B power station - which in 2012 cost £600m - if everyone in the UK switched their lights to LED, the country wouldn’t have to build three more power stations to cope with demand. It’s another reason why we’ve launched our Switch the Lights campaign. As we report, the UK is facing an energy crisis. Blackouts, or brownouts, are a very real possibility unless we spend £100bn on energy infrastructure. But UK retailers can limit the damage by changing to LED. It’s a smart move, not just because of lower bills, and lower emissions.

But also because a blackout means candles, dusty old board games and no TV. And for retailers, lost sales. And no one can afford that.
