This is not true at all. At best, renewables can manage a streak of 5 hours a day or 10 hours a day if lucky. I am sure you read, “This country ran on 100% renewable energy.” The catch is, it is not the norm, but lucky weather. I live in Texas. Texas ran on 100% renewables for several hours. That is no reassurance when a cold snap, cloudy weather, or stagnant wind. With fossil fuels, you can adjust the supply according to forecasted demand. You can’t do that with wind and solar. Batteries make a very tiny portion of the grid infrastructure as well. They’re not replacing natural gas plants anytime soon. At the same time, government subsidies supplant reliable energy with unreliable energy. I am not against green energy when it is applied correctly, but you can’t run an entire grid on renewables and not expect complications.
