The Sun follows a line from midnight (left) to noon (right) and back, on this day. When a line is above the horizontal diameter, it's daytime. At latitude 90°N, the line is horizontal (the Sun doesn't set). Vertical line: at the equator. Hour circles (dashed), altitude scale around the diagram. 2/3

Range anxiety is not a valid excuse to not own an EV. EVs today have 250-300 miles range & high-end ones have almost double that. Most of the U.S. is now within a 50-mile driving radius of an EV DC fast charger. And much of it is with a 10-mile radius. 🧪💡🔌☀️💨💧🔋 www.nytimes.com/interactive/...
