Power Plant IM, Charleroi, Belgium
Once known for being the biggest coal burning power plant in Belgium, the Power Plant IM was built in 1921. It was able to cool down 480,000 gallons of water, but at a great cost: it resulted in 10% of carbon dioxide emissions in the whole country. After many Greenpeace protests, it was finally shut down in 2007.
Hashima Island, Nagasaki, Japan
The now-deserted Hashima Island was actually once the most densely populated island in the entire world. Its appeal was an underwater coal deposit located right under the island. However, once the coal ran out, its population began to dwindle and has since become an empty ghost town.
