About Photovoltaic Energy StorageDisplacement is a vector measure of the interval between two locations measured along the shortest path connecting them. How far does the Earth travel in one year? In terms of distance, quite far (the circumference of the Earth''s orbit is nearly one trillion meters), but in terms of displacement, not far at all (in some respects, zero).
