energy transition and the socially and economically just transition of the energy system are not sufficiently discussed in terms of social needs. EPN has 50,000 members working for 34 labour unions of public energy corporations. Job transition programmes, including re­education and training, are required for a socially and economically just and smooth job transition. However, one EPN member, the KHNP labour union, opposes suspension of Shin­Kori 5 and 6 construction only because of the impact it would have on the employers of the construction companies contracted to build Shin-Kori 5 and 6. Finally, the KHNP labour union and the labour union of the Korea Electric Power Corporation(KEPCO) left the EPN in the process of public engagement process on Shin-Kori 5 and 6 reactors. 4. Potential of energy efficiency and renewable energy Decreasing energy consumption through energy conservation and efficiency improvement and increasing the use of renewable energy are important methods of climate-sensitive energy use. After a peak in 2010 at a rate of 10.1 per cent, the trend suggests that annual growth rates of electricity consumption have slowed down: 4.8 per cent in 2011, 2.5 per cent in 2012, 1.8 per cent in 2013, 0.6 per cent in 2014 and 1.3 per cent in 2015. The projection by the former government, on an average growth rate of 2.2 per cent of electricity consumption by 2029, has not borne out since 2013. The new government released renewed projection of electricity demand by 2030 in order to prepare the 8 th Master Plan on Electricity Demand and Supply, in which electricity demand in 2030 was reduced 11.3GW from 113.2GW to 101.9GW. The“energy consumption value(TOE per 1 million US dollars)”, as the national index of energy efficiency, had a slightly improving trend from 2008 to 2014. The energy consumption value is the same as energy intensity, which is the amount of primary energy consumption used to create one unit of GDP. It has since improved, moving from 0.204 in 2008 to 0.198 in 2014. The second Basic Energy Plan established by the Park government in 2013 proposed the goal of reducing final energy consumption by 2035 by 13 per cent and electricity consumption to 15 per cent, in relation to the business-as-usual level. When looking at the proportions of power generated by new and renewable energy in 2014, waste led the pack, at 60.6 per cent, followed by biomass, at 15 per cent, solar energy, at 10.7 per cent, hydraulic power, at 5.8 per cent, wind power, at 3.6 per cent, fuel cell, at 2.9 per cent and ocean energy, at 1.3 per cent. The Park government, in the second Energy Basic Plan, announced that it will decrease the proportion of waste to 47.3 per cent among primary energy sources by 2020 to 29.2 per cent by 2035, although it will still contribute the largest proportion of energy. The Park government planned to expand new and renewable energy sources by 2035 with the following targets: waste at 29.2 per cent, wind power at 18.2 per cent, biomass at 17.2 per cent, solar energy at 14.1 per cent, geothermal heat at 8.5 per cent, solar power at 7.9 per cent, hydraulic power at 2.9 per cent and ocean energy at 1.3 per cent. The four new and renewable energy sources with the highest potential for expansion at that time are waste, wind power, biomass and solar power. The proportion of new and renewable energy supply in relation to primary energy sources was 4.3 per cent in 2015. When the government at that time created the second Basic Energy 19
