Industry minister Toshimitsu Motegi said Friday the administration will start working on setting a goal in three years for the best national energy mix and reach it within the following 10 years, taking into account the amount of renewable energy available and the number of nuclear reactors in service.

Motegi said he will consider moving up the schedule for setting the target if possible.

The government is in the process of crafting a medium- to long-term energy plan that reflects the situation in the face of the Fukushima catastrophe, which has raised concerns over the use of nuclear power.
