A vertical axis wind turbine comprising at least two rotor portions, each portion having a bottom, a top, and a curved horizontal cross section when seen in top view. A top cap may be provided that has a convex portion corresponding to each rotor portion that extends forwardly in a windward direction. Each rotor portion may comprise two angled rotor sections that meet at substantially a vertical midpoint of the rotor portion. The angled sections may be angled rearwardly in a leeward direction and/or radially and may be angled from 1 to 20 degrees with respect to vertical. There may be three or more rotor portions and the turbine may be comprised of one or more vertically stacked sections.
