Is solar power getting cheaper?
As of 2024, cost of solar electricity is 0.043 $/kWh: −90% since 2010.
Why it changed
When solar power is cheaper than fossil fuels, leaving coal becomes an economic choice, not only an environmental one. At the same time, 2024 brought IRENA's first year-on-year uptick in LCOE in a decade, the long-run decline since 2010 (−90%) remains unprecedented.
