This document summarizes Taiwan's energy sector challenges. Taiwan imports over 99% of its energy needs and relies heavily on fossil fuels like coal and petroleum. This dependence raises issues around energy affordability, environmental responsibility, and energy security. To address these non-market issues, Taiwan is pursuing policies to improve energy efficiency, develop renewable energy, and mitigate energy dependence. However, challenges remain around incentivizing renewable adoption, balancing stakeholder interests regarding nuclear power, and reducing reliance on imports given Taiwan's limited domestic energy resources.
