Japan is expected to unveil its new energy policy on Monday.
According to reports, the government may announce plans to phase out nuclear energy by 2030.
This comes after last year's earthquake and tsunami which crippled a nuclear plant run by Tokyo Electric Power Company (Tepco) and sparked a radiation crisis.
The BBC's Mariko Oi spoke to the president of Tepco, and asked what kind of impact a no-nuclear policy would have.
