Australia just activated its largest clean energy project in history. The scale is difficult to comprehend.

Built in Queensland, the Western Downs renewable energy hub covers 18,000 hectares. It holds six gigawatts of solar panels on the ground and four gigawatts of wind turbines towering directly above them.

But the real engineering feat is the balance. They solved the most persistent problem with renewables—the sudden drop-offs. When the midday sun peaks, solar takes the load. When the sun dips in the morning and evening, the wind picks up. The result is a remarkably steady curve of combined output that lasts for 18 hours a day.

It generates enough electricity to cover the entire country’s daytime demand at peak generation. To handle the load, engineers had to build a dedicated 1,000-kilometer high-voltage transmission line just to plug the hub into the eastern grid.
