Wind has a similar trajectory to solar but started earlier and is basically a simpler and more efficient technology. Most wind turbines are about 30% capacity and 35% efficient. The Betz Law limits the amount of efficiency available to 59.6% and much ingenuity has gone into making real world efficiency as high as it is. Wind power has arguably the most different kinds of configurations with vertical, horizontal and blade-less turbines being three major types, but we only require to use the systems that are already proven and whose cost per generated kilowatt hour (kWh) is lowest and most reliable.
