Electricity Supplied by Nuclear Energy

In 2011 the world's nuclear reactors supplied 2518 TWh of electricity (2518 billion kilowatt hours)a. This represents around 13% of global electricity consumption.b

The percentage of electricity supplied by nuclear generation and amount of electricity supplied in TWh for those countries with nuclear generation in 2011 is shown below:
