Vending machines are very inefficient because they run for 24 hours. Japan has 5.4 million vending machines, half of which are for beverages. If all the refrigerated beverage vendors were eliminated, one of Japan's 55 nuclear reactors could be completely shut down.

Ikoma City is taking the green step to eliminate all vending machines in city buildings. Cold drinks will still be available, but in more energy efficient coolers.

Implications - This subtle change in product placement will have a huge impact on the environment. Hopefully other countries become inspired by this simple, yet simply huge change and adopt it for themselves. It's definitely an easy and more affordable way to contribute to cleaning the environment.
