Since the launch of the Energiewende (Energy Transition) in Germany in 2010, the concept influences on energy and climate policies around the globe. In May 2016, the Taiwan government began promoting renewable energy (RE) and phasing out nuclear power. However, it has not used the Renewable Energy Development Act, which is similar to the German Erneuerbare Energien Gesetz, as the main instrument. Instead, the new government has prioritised the revision of the Electricity Act and the introduction of liberalisation to allow RE producers to compete in the market and sell directly to end consumers. The main purposes of this article are to provide a critical review of this unique way of promoting RE under an energy transition and to determine the significance of Germany's energy transition strategy as a framework to promote RE development. The finding is that ambitious RE promotion schemes should remain at the core of energy transitions, while the liberalisation of electricity could play a supplementary role in an interconnected continental energy system to mitigate intermittency, which is one of the weaknesses of RE. Permitting expensive RE to be sold directly at the low market price of electricity would fail to give impetus to further RE development.
