The government plans to announce in its long-term energy strategy that renewables are a "major" energy source while continuing to support nuclear power because of its zero carbon emissions, a draft of the plan said Friday.

The industry ministry presented the draft to a roundtable of experts studying the nation's energy policy through 2050, calling renewables an "energy source whose possibility of becoming a major (source) is greatly increasing."

Although attention has been on whether a raw breakdown of the country's future energy mix will be included, the government is likely to postpone setting such numerical targets.
