The BIGGEST problem with clean energy

How about winter, just like Texas last winter, solar panels covered in snow, wind turbines iced up and unable to spin. No electricity. There needs to remain some sort of backup that can handle most of the load, for winter or emergency use. Their dream is a nightmare. Now add in making everyone drive electric cars, they'll need charging, and the entire grid goes down, when one more car than the system can handle gets plugged in. It sounds great to a layman, but to an engineer, it's a nightmare. We're not equipped yet for what they want now. Our electrical grid is already at a tipping point, and they want to add to that. Good luck, your nice electric car will stay low milage when it sits in your blackened garage, with no electricity to charge it up.
