Fig. 2: Economic assessment of renewable electricity, heat, and total electrification costs under expansion scenarios.
From: Aligning EU energy security and climate mitigation through targeted transition strategies

a–d Range of levelized cost of electricity (LCOE, $ kWh-1) and levelized cost of heat (LCOHe, $ kWh-1) from solar and wind power expansion in 2024 and under slow, nominal, and fast cost-reduction trajectories by 2050. e,f Total annual cost of electrification potential ($bn) under renewable-capacity scenarios (BAU-solar, BAU-wind, PARTIAL-solar, PARTIAL-wind, FULL-solar, and FULL-wind) through 2050. The shaded ranges in (a–f) represent the envelope of outcomes derived from variations in interest rate, battery-storage inclusion, NUTS2-level solar irradiation and wind power output profiles across EU countries, and technology cost trajectories.
