New aerodynamically improved rotors for use in vertical axis wind turbine (VAWTs) are disclosed. In some examples, the VAWT rotors include one or more blades with an aerodynamic front shape with low drag coefficient and a blunt or concave back shape that effectively catches the wind. Example rotors can be used by themselves or in conjunction with vertically attached rotating airfoils. The new rotors add to the overall energy production while acting as supports for the vertical airfoils. Furthermore, the new rotors provide energy in low wind speed conditions where the vertical airfoils are ineffective and can act as jump starters for the vertical airfoils. Guy wire structures for stabilizing VAWTs are also disclosed. The structures allow for reduced construction costs for a given tower height compared to conventional HAWTs and allows for taller towers for a given construction cost. The overall stability under wind gusts is improved by the guy wire design
