I read this article yesterday, (can you believe I didn't post it? lol) it has a bit about vending machines and the power they use that I found interesting...
Japan still struggling to restore power to cool down reactors
Excerpt:
Nearly 1 million homes remained without electricity in the quake zone, and rolling blackouts have been taking place elsewhere. As the threat of blackouts has intensified,
one activist called on Japan to unplug millions of vending machines that dispense everything from hot corn soup to bouquets of flowers.
Japan has
5.5 million vending machines, each using as much power as an average household, said Canadian speechwriter and publicist John Harris, who is based in Japan's Chiba prefecture. Add that up, and it
requires as much power as the entire capacity of the troubled Fukushima nuclear plant at a time when Japanese are being asked to conserve electricity, he said.
The nearly
1 million machines operated by Coca-Cola, which because they use both refrigeration and heating are the
"biggest power hogs," are still running even as train service is curtailed, he said.
