South Korea ranks 15th among G-20 nations for overall clean energy investment. Ninety percent of its clean energy investments are in the solar sector. In October 2012, South Korea published a new emissions target equivalent to a 3% reduction in 2013. A nationwide emissions trading scheme affecting 377 companies will be established in 2015 as part of a long-term energy and climate change plan,
which may also include linking energy taxation to emissions and establishing a nationwide smart grid by 2016.
A key government goal is to slash carbon emissions by 30 percent by 2020 from its business as usual case. South Korea is planning a complex to install 500 wind turbines that are in 5MW class. This is 3rd largest scale in the world. According to the plan, about 100MW in 2013, additional 900MW in 2016, and the generation capacity will reach 1.5GW by 2019. The South Korean government has also established an 11 percent renewable energy goal in its total primary energy supply by 2030, identifying some key technologies such as solar thermal, photovoltaics, geothermal and bioenergy. Currently, the share of renewables in South Korea’s total primary energy supply is the lowest among member nations of the OECD.
