About 20% of the world's energy supply comes from 440 nuclear power plants, located in 25 countries around the world.
About 12% of these nuclear reactors are in Japan.As the headlines describe, the devastating earthquake and tsunami that struck Japan on March 11 triggered a series of explosions, leading to the partial meltdown of a nuclear plant, located 150 miles outside of Tokyo.
The impact of the meltdown has spread far beyond Japan, affecting nuclear-power companies worldwide.
Observers suspected plans for many of the world's 60 new nuclear plants could be stopped, or at the very least halted, for some time to come.
This week, the Swiss government announced the suspension of approvals for new nuclear plants. The German government followed suit.
Furthermore, Germany's seven nuclear facilities, built prior to 1980, will be shut down until at least May.
