David Wojick, Heartland Institute, Ph.D. Philosophy of Science and Mathematical Logic, B.Sc. Civil Engineering: The brutal cold wave that just struck America provides a stark example of why 100% renewables cannot possibly work. Once the massive high pressure system was in place there was almost no wind, so no significant wind power. And the coldest temperatures by far were at night or early morning, when there was no solar power either. The first drawing shows Germany aiming for 100% wind and solar and they are using coal as backup, essentially no reduction in fossil fuel capacity. Colorado and California are mandating 100% wind and solar (with fossil fuel backup?). It is the worse possible energy plan for modern economies. Thank the politicians who planned this.
