Opposition vice presidential candidates challenged the government’s energy policy during Monday’s televised debate, while the ruling Democratic Progressive Party’s (DPP) vice presidential candidate questioned their positions on nuclear power.

Since taking power in 2016, the government’s energy policy has focused on phasing out nuclear power and running an electricity mix of 50 percent natural gas, 30 percent coal and 20 percent from renewable energy sources by next year.

Opposition parties have criticized the policy, especially as the rollout of renewable energy sources has lagged behind schedule, arguing in favor of maintaining Taiwan’s nuclear power generation capabilities.
