In 2014, the Korean government relieved the restrictions for land-based wind turbine site development and simplified the approval process. This change has encouraged investment in wind energy. In 2016, Korea installed 182 MW of new wind energy capacity, a 21% increase that brought accumulated wind power slightly over 1 GW. In 2017, the country installed an estimated 130 MW.
However, most ship building and heavy industry companies have closed their businesses because of slow technology development and severe competition. The number of manufacturers was also decreased in 2016. The number of companies involved in wind energy shifted from 34 in 2014 to 37 in 2015, before dropping to 30 in 2016. The wind sector employed an estimated 2,424 Koreans in 2014 and 2,369 in 2015; this decreased further to 1,813 in 2016. Complicated wind farm constructions were a large contributor to this decline in sales, number of companies, and employees.
