The vertical wind generators are even called as vertical axis wind turbine (VAWT). This wind powered turbine has been designed for a specific purpose. This can get fixed to the flat roof or stand on a platform in both the rural and urban environments. This electricity producer has several benefits. It can be installed close to the land surface. It is not required for the tower to prop the generator as the generator can also be placed on the ground. Moreover it is not necessary that the turbine points in the direction of the wind.
The vertical wind generator has its pros and the cons. The disadvantages include that they cannot be mounted easily. It is a Herculean task to fix the vertical wind turbines on the towers. Since they are close to the ground, where the air flow is less as compared to the higher altitudes, the efficiency levels dip. This results in a production of around 50-60% less electricity. Another common disadvantage is that they require guide ropes to hold the shaft in place.
The fact that the rotor blades are vertical has some advantages too. He need for a fulcrum is reduced and the bearing is not required. This lowers the cost of installation. The vertical wind generators can be installed at lower heights especially in the places where laws regarding the height are strict. These turbines have very little vibrations. They do not kill the birds. They are able to capture wind from any direction. They produce relatively less sound and they are stackable. The vertical wind generators are an average performer of renewable energy sources. The vertical construction is quieter than the horizontal one.
The shaft in the vertical axis wind generators is perpendicular to the ground. These require a large area for installation. These wind turbines incline to assuage some environmental worries associated with large scale blade turbines. Although the more common type of wind turbine is the horizontal wind axis wind turbine, but vertical wind turbines are also seen at certain places.
There has been some growing demand in the vertical wind generators. Modern designs do not require the guide ropes and there is a growing market for home, vertical axis wind turbines.
Many people are investing in the greener sources of energy in order to generate clean and green electricity. Dependence on the fossil fuels has to decrease for a safer and healthier environment.
