Chart: levelized cost of electricity ($/MWh) vs. cumulative global installed capacity (GW, log scale), 2010 to 2024. Solar fell from $417 to $43/MWh as capacity grew from 40 to 2,200 GW. Onshore wind fell from $111 to $34 (180 → 1,052 GW). Offshore wind fell from $203 to $79 (3 → 83 GW). Nuclear rose from $96 to $182 at roughly flat capacity near 390 GW. Coal rose from $102 to $122 (1,700 → 2,175 GW). Renewables are IRENA global weighted averages; nuclear and coal are Lazard US midpoints.
A graph showing the levalized cost of energy over time, broken up by source of energy. It shows the radical decrease in solar energy cost per megawatt over time.
