what is green growth?

Green growth is to materialize the co-existence of environment and economy

• economic growth to improve environmental condition
  • pursue the eco efficiency to maximize the efficiency of resource use and minimize the environmental pollution
• economic growth to take the environment as the new growth engine
  • make green technology and green industry to increase environment friendly economic activity as a growth engine

3 factors of green growth

• to minimize the use of energy and resources while pursuing the solid growth
• to minimize the environment pollution such as green house gas emission while using the same energy and natural resources
• develop the green technology and clean energy as the new growth engine

the direction to lead low carbon green growth

the current situation of leading low carbon green growth

• motor car regenerative energy
  • use the regenerative energy to take place when the car stops to the nearby motor car first and surplus power needs to be changed into AC through the inverter and be used as support power source and station power and lighting power source.
    ☞ about 33,000MWh can be saved annually.
• solar energy development business
  • To comply with the government's policy to supply more new and regenerative energy, we collects funds from the private sector and install the solar energy power plant using the building roof of Hopo depot with good solar radiation condition. Promoting Solar Power Generation Project.
    ☞ the size of energy generation : 1.5MW, annually generated energy amount : 1,807MWh(Hopo depot)
    ☞ the size of energy generation : 1.7MW, annually generated energy amount : 2,048MWh(Nopo depot)
    ☞ the size of energy generation : 1.0MW, annually generated energy amount : 1,205MWh(Daejeo depot)
  • Solar Power Generation Project will be promoted in depot and other idle site by collecting citizen fund for Solar Power.
• the business to improve heat environment at the platform
  • The amount of electricity used and water resource are saved by utilizing runoff groundwater generated in urban rail platform and tunnels, and applying to urban rail platform cooling system ( Completed applying 19 Platforms)
    ☞ Leaked ground water of 7,367 ton a day is used as water resource for tunnel water washing, station rest room, filter washing water, nearby building daily life, road water cleaning, road heat island prevention, lift heat surrounding improvement, and stream drying prevention etc.(use rate: 51.21%)
• Study on development for cooling and heating system using unused energy in urban rail.
  • Collect unused heat sources such as ground water and air in the underground and use apply them for cooling and heating.
  • Development of Dust Collection System for Ultrafine Dust (PM2.5)
• energy saving through peak power use control
  • Try to save electrical energy through peak power value control by stopping to use ventilation device temporarily when the sudden electricity use is increased in the section of urban rail line 3 hydro-electric power substation.
• Join the national green house gas reduction program through participating car use according to day, carbon point system and carbon neutral program.
• green consumption activation, green land environment composition, making efforts to activate green traffic and public transportation (such as promotion)
