Wind Turbines

With the issues of global warming, greenhouse gases, acid rain and pollution on the global agenda, people are turning at an ever increasing rate to green energy options. One of these options is harnessing wind energy which is either used directly for mechanical work or for producing electricity.

Although wind turbines have been used for harvesting energy for hundreds of years, they have been gaining popularity. Wind turbines have the capacity to produce clean, green energy.

They can produce energy with minimal environmental impact. They don't pollute or produce greenhouse gases and they don't contribute to global warming. In addition, the new generation of windmill is much more aesthetic and quieter than their predecessors.

Energy and Cost Savings

Cost savings are an important consideration when choosing an energy source. Wind is a great source of energy because it is free and, in most locations, there is an almost continuous supply. Once a wind turbine has been installed, other than standard maintenance, it requires very little further expenditure.

As people are becoming aware of wind turbines as a feasible source of energy, the demand for them is increasing. They are very versatile and can be used on individual properties, on farms or planted in wind farms to harness energy. Generally farmed energy is fed directly into the grid.

Wind Turbine Models

There are two main types of wind turbines: the horizontal-axis, which is the traditional wind turbine design, and vertical-axis wind turbines which are the new generation design.

Generally horizontal axis wind turbines need less wind and tend to be quieter than vertical wind turbines. This style of wind turbine is generally installed in wind farms. They are usually three bladed, computer controlled and pointed into the wind to maximize harvest.

Vertical axis wind turbines are often considered to be better suited to domestic and local use for a number of reasons. They operate effectively with wind coming from any direction and they are quieter than horizontal wind turbines. In addition they can be easily attached to a roof and they have shorter towers.

The Future of Wind Turbines

As wind turbines become more popular, companies and governments are putting more resources into improving the design. Wind turbines are likely to hold a special place in future energy production.

With significant advancements in turbine technology, production and distribution, they are becoming much more accessible and economical to purchase.
