Each year nuclear adds only as much net global power capacity as renewables add every two days.
The long-standing argument that renewables lack reliability no longer holds. Today, renewables can deliver reliable, round‑the‑clock power.
24/7 renewables: The economics of firm solar and wind confirms that in prime solar and wind regions, hybrid solutions combined with storage deliver round-the-clock power at lower costs than fossil fuels
Firm levelised costs of electricity (‘firm costs’) for solar plus storage range from USD 54 to USD 82 per megawatt-hour (MWh) in high-quality resource regions, compared with USD 70–85 per MWh for new coal in China and more than USD 100 per MWh for new gas globally.
