For a long time, society has adopted green energy sources like solar panels and wind turbines. But what happens when the sun doesn’t shine or the wind doesn’t blow? Nature can be unpredictable, which presents a problem. Humanity needs a consistent energy supply to go about their day. Are there other, more reliable options? What Are Sand Batteries? Sand batteries serve as thermal energy storage units. They use low-grade sand as a medium to store thermal energy generated by renewable energy sources like solar or wind. These energy sources heat the sand to high temperatures — at around 500 degrees Celsius or 932 degrees Fahrenheit. The hot sand can then hold the…
