Photos: Interactive dancefloor and eco partying at Club Watt

If you believe Club Watt's maths, going clubbing is greener than staying in. It reckons you'd use more electricity at its new building than spending the evening at home.

It also has a diverse and decent-looking roster of DJs and acts to tempt clubbers off their sofas, starting with Baltimore hip-hop act Meet the Streets on 5 September.
