Recent analysis of carbon taxation proves that reinvestment of the revenue into industries such as renewable energy enables recovery of a part of GDP lost to GHG reductions. The Korean government goal is to increase the share of new and renewable energy to 4.3% in 2015, 6.1% in 2020, and 11% in 2030. To do so, a feed-in tariff (FIT) system and renewable portfolio system (RPS) have been implemented. The cost of solar photovoltaic electricity is as high as 710 KRW per kilowatt and 108 KRW for wind (whose baseline generation costs are much less). Subsidy based on FIT amounted to USD 243.1 million for 1 503 gigawatt hours of electricity generation in 291 units in 2009.
