Myth: Cloudy days present a real challenge to solar, wind and battery meeting daily global energy demands as weather fluctuates

 |  6 May 2024

False. Our research has shown that even in high-latitude regions a solar, wind and battery system (SWB) optimized for cost needs only a few days' worth of battery energy storage.

Long stretches of cloudy winter days when available sunshine is at its minimum are typically the greatest challenge to SWB-based energy systems. However, our research has shown that even in high-latitude regions an SWB-based system optimized for cost needs only a few days' worth of battery energy storage.

The key to understanding cost-optimization of SWB-based energy systems is the Clean Energy U-Curve.

Witness the transformation

A global clean energy system run by 100% SWB is both possible and inevitable for nations all over the world, regardless of geography and weather fluctuations.
