International mini-market chain 7-11 is greening up its act in 100 new eco-friendly stores in Japan.

These stores, which feature wind power and LED lights, cost up to 30% more than a traditional stores. But Sevs and other chain markets like it expect that the cost of “greening” buildings will go down as demand rises.

That would be pretty cool, huh?
