"PV has become the cheapest source of electrical power in regions with a high potential, with price bids as low as 0.01567 US$/kWh[1] in 2020. Panel prices have dropped by the factor of 10 within a decade. This competitiveness opens the path to a global transition to sustainable energy which would be required help to mitigate global warming. The situation is urgent: The emissions budget for CO
2 to meet the 1.5 degree target would be used up in 2028 if emissions remain on the current level. However, the use of PV as a main source requires energy storage systems or global distribution by High-voltage direct current power lines causing additional costs. "

Capital costs[edit]
For power generation capacity capital costs are often expressed as overnight cost per watt. Estimated costs are:
- gas/oil combined cycle power plant - $1000/kW (2019)[10]
- onshore wind - $1600/kW (2019)[10]
- offshore wind - $6500/kW (2019)[10]
- solar PV (fixed) - $1060/kW (utility),[11] $1800/kW (2019)[10]
- solar PV (tracking)- $1130/kW (utility)[11] $2000/kW (2019)[10]
- battery storage power - $2000/kW (2019)[10]
- conventional hydropower - $2680/kW (2019)[10]
- geothermal - $2800/kW (2019)[10]
- coal (with SO2 and NOx controls)- $3500–3800/kW[12]
- advanced nuclear - $6000/kW (2019)[10]
- fuel cells - $7200/kW (2019)[10]
