Renewable energy like solar and wind power is growing globally, but there are challenges in using it, especially in Korea. To tackle this, Korea is changing its policies to support more renewable energy. In the past, renewable energy wasn't a big focus, but in 2017, Korea decided to phase out nuclear plants and use more renewable energy. The government wants to reach their goal of using more renewable energy by 3020. Challenges include planning projects, limited space for installations, and policies focusing too much on quantity. By understanding these challenges, Korea can create better policies to reach their renewable energy goals.
