Reappearance of wind energy
In the late 1960s, wind energy was again valued. The book “Silent Spring” (Carson, 1962) made people understand the impact of industrial development on the environment. The book “Limits to Growth” (Meadows et al., 1972) shows in the same mood that unrestricted development will inevitably lead to disasters or changes. People recognize that fossil fuels…

Early wind power
Compared with the use of wind to generate mechanical power, the early use of wind energy to generate electricity was attributed to the successful commercial development of small wind turbines, which were subsequently applied to large wind turbines through research and experiments. When the generator appeared at the end of the 19th century, people had…

The history of wind energy utilization and the history of windmills
It is necessary to review some history of wind energy utilization, because we can understand the many problems that the wind energy utilization system still faces today and can explain the basis of the current wind energy model. The following overview focuses on wind turbine concepts that are particularly relevant to today’s applications. The earliest…

The second part of the basic structure of the horizontal axis lift wind turbine
Tower and foundationThis part includes the tower structure and supporting foundation. The towers currently in use mainly include steel tube independent towers, truss towers and concrete towers. Small wind turbines also use wire-supported towers; the height of the tower is usually 1 to 1.5 times the diameter of the wind wheel, but At least 20m…

The basic structure of the horizontal axis lift wind turbine
Wind wheelThe wind wheel of a wind turbine is composed of wheels and blades. In terms of performance and overall cost, they are the most important components of the wind turbine. Today’s main wind turbines have three blades in the upwind direction, and some have two blades in the downwind direction. There used to be…

Modern wind turbine and modern wind turbine design
The wind turbine introduced on this website is a machine that converts phoenix energy into electrical energy, which is different from the “windmill” that converts wind energy into mechanical energy. As generators, wind turbines are connected to the power grid. These networks include battery charging circuits, power supply systems in residential areas, isolated or regional…

Alternative energy: wind energy and its historical development
Wind energy has once again become an important resource of the world’s energy is one of the significant developments in the energy industry at the end of the 20th century. The invention of the steam engine and the emergence of other industrial technologies that convert fossil fuels into useful energy sources seem to make wind…
