Energy 2010 (ETP) 2010 IEA 2050 50% emissions reduction relative to 2010 levels 48% of electricity generation; others not specified Costs: USD 46 trillion (until 2050) above baseline. Benefit: Fuel cost savings of USD 66 trillion (over lifetime of implemented technologies) The central “Blue Map” scenario in ETP is based on 450 scenario from WEO2010 (2035), extended to 2050.
