Soon you can add a night out clubbing to your bag of green tricks. A new technology developed by the environmental innovation lab Enviu takes advantage of the vast amount of energy expended by revellers as they throw themselves around the dance floor. And its debut is right around the corner. On September 2, Iggy Pop will be performing at Club Watt in Rotterdam, Holland. And those on the dance floor will play their part in keeping the lights lit and the bass thumping.

"When you dance, you generate energy by the shaking of the ground," Stef van Dongen, director of environmental innovation lab Enviu, explains. "What we do, very simply, is to capture the movement of dancing people and transform it into energy."

The club will be among the first in the world to give back some of what dancers leave on the floor -- and it is part of a larger effort by Enviu subsidiary Sustainable Dance Club (SDC) to introduce environmental technology to an industry that has traditionally been a voracious consumer of electricity. Your average nightclub swallows up 150 times the amount of power normal households do. Club Watt plans to use 30 percent less.

Some of that savings is to come from a technology known as electromagnetic induction. The system, developed by SDC together with scientists at the Technical University of Delft and architects from a Dutch firm called Döll, involves a network of springs and magnets that convert downward movement mechanically into energy.

Club Watt, of course, doesn't want its floor to be too bouncy -- otherwise its dancers might be thrown off balance. But the floor will have a give of one centimeter, enough to generate 5 to 10 watts of electricity per dancer. SDC estimates the eco-club will require about 2,000 people moving at once to keep the place bright.

The move isn't one born purely of ecological altruism. Even as environmentalists are better known for tree-hugging asceticism than night club hedonism, the Dutch are -- like most Europeans these days -- anxious to do their part for the environment. A survey conducted by SDC last year found that fully 66 percent of Dutch clubbers would be willing to dig deeper into their wallets for a green night out. Enviu -- which is also helping the port in Rotterdam, Europe's largest, reduce its emissions -- could do worse than starting in the clubbing capital of the Netherlands. Over 10,000 people go out in the city each weekend.

And Club Watt is just the beginning. The Sustainable Dance Club concept has also set out a list of rules that clubs must adhere to if they want to earn the SDC label. To meet SDC standards, for example, a club must reduce energy consumption by at least 30 percent and waste production by 50 percent.

"One club wants a green roof, so maybe we'll put solar panels up there, or grow things, put up little windmills, who knows," said van Dongen. "Doing something is better than doing nothing, but to earn the label 'sustainable dance club' you have to do more."

At Club Watt, for example, the dance floor is just one of the energy saving novelties being introduced. LED lights will be used as will wind and solar power. The wine will be on tap to reduce bottle waste and drinks will be delivered in large, reusable containers. Even lost and found clothing will be re-used -- as insulation. Rainwater collected on the roof funnels into the club's plumbing system.

Club Watt isn't the first eco-club on the block. Billing itself as the " world's first ecological nightclub," Club Surya opened in London on July 10 with organic, fair trade alcohol, a bar constructed of used cell phones and other eco trimmings, including a small, power-generating dance floor.
