Germany has unveiled plans to shut all its nuclear reactors by 2022, prompted by Japan's nuclear disaster.

The German government unveiled plans to keep the eight nuclear reactors closed, following their suspension in March 2011.

The phase-out plan will be submitted for approval in the parliament.

The nation receives 23% of its power from its 17 nuclear reactors, nine of which are currently running at full capacity.

Germany plans to cut electricity usage by 10% and plans to increase renewable energy usage to 25% by 2020.
