Former Norwegian Prime Minister Gro Harlem Brundtland says neither nuclear power nor fossil fuel is a sustainable solution to the world's energy problem, and governments have to balance the risks of how they are used.
Brundtland is visiting Taiwan for the Gro Brundtland Week of Women in Sustainable Development.
The government here is seeking to phase out nuclear energy by 2025, but faces the dilemma of having to expand coal-fired power plants to prevent a power shortage.
And speaking in Taipei, Brundtland said while it is difficult for her to comment on Taiwan's case because she was not familiar with the details, such issues are not uncommon dilemma.
According to Brundtland, a similar dilemma arose when she was chair person of the United Nations World Commission on Environment and Development and it was difficult then to reach consensus on what they should do with nuclear energy.
Brundtland was awarded the first Tang Prize in sustainable development in 2014.
