The fact that a power source with an efficiency of mere 30 percent is being pitched as a power source of the future will no doubt come as a surprise for many. In order to understand the intricacies of the entire matter, we need to go through the basics of wind power generation – right from how wind energy is converted into electricity.

The theoretical maximum efficiency of a turbine is ~59%, also known as the Betz Limit. Most turbines extract ~50% of the energy from the wind that passes through the rotor area. 9 The capacity factor of a wind turbine is its average power output divided by its maximum power capability. 9 On land, capacity factors range from 0.26 to 0.52. 11 The ...

power plants convert the energy in flowing water into electricity. The most common form of hydropower uses a dam on a river to retain a large reservoir of water. Water is released through turbines to generate power. "Run of the river" systems, how-ever, divert water from the river and direct it through a pipeline to a turbine.

Wind power production itself has increased by around 26% each year for the past two decades, bringing us to our current figures. And because wind power has become the lowest-cost option for adding new power capacity to the grid, wind energy is on the rise and is expected to continue on that line for decades and centuries to come.
