Detailed system planning for new generation and transmission infrastructure is used to ensure that the electric system can be operated reliably and economically in the future. Advanced planning is required due, in part, to the long-time horizons required to build new electricity infrastructure. More specifically, electric system planners must evaluate the adequacy of transmission to deliver electricity to demand centres and the adequacy of generation to maintain a balance between supply and demand under a variety of operating conditions. 

In just a few short decades wind energy has matured dramatically, making wind one of the fastest growing sources of electricity in the world today. Due to technological advancements, policy initiatives, and economic drivers, wind energy is now able to make a cost-competitive contribution to our growing energy needs. Turbines today are sleek and slender machines, a far cry from their bucolic wooden ancestors. Around the world, wind turbines of all sizes have become a familiar sight; ranging from home or farm-scale machines of 1 kilowatt (kW), all the way up to arrays of large 3 megawatt (MW) machines.

To participate in wind energy, you will need to make decisions about numerous options that exist for harvesting the wind. You should consider all your options before proceeding, since each option has its own risks and rewards. Additionally, there are various financial incentives and markets that may or may not apply to your situation. If incentives are available to you, these can also influence which option you choose. This fact sheet will help you begin to understand the basic options for participating in wind energy.

When you picture a wind farm, chances are you imagine vast expanses of open land, dotted with towering turbines. But there's another type of wind farm you might not have considered: one that shares space with crops and livestock. Wind energy and agriculture are a natural fit. Farmers and ranchers have long taken advantage of the breeze to cool barns and dry grain. Now, they're also harnessing that wind power to generate electricity.

Due to technical and economic visibility, wind power has emerged as one of the most promising renewable energy sources (RES) in recent years. Wind energy capacity can range from a few kilowatts to many megawatts and can be found in many applications. Wind energy can be used in both minor off-grid systems and substantial wind farms connected to the grid. This sort of distributed generation poses issues with the interconnection system due to the absence of active and reactive power control. 

One of the most important economic benefits of wind power is that it reduces the exposure of our economies to fuel price volatility. This benefit is so sizable that it could easily justify a larger share of wind energy in most European countries, even if wind were more expensive per kWh than other forms of power generation. This risk reduction from wind energy is presently not accounted for by standard methods for calculating the cost of energy, which have been used by public authorities for more than a century. Quite the contrary, current calculation methods blatantly favour the use of high-risk options for power generation. In a situation where the industrialized world is becoming ever more dependent on importing fuel from politically unstable areas at unpredictable and higher prices, this aspect merits immediate attention.

The theoretical potential for wind, as estimated by the global annual flux, has been estimated at 6,000 EJ/yr. The global technical potential for wind energy, meanwhile, is not fixed, but is instead related to the status of the technology and assumptions made regarding other constraints to wind energy development. Nonetheless, a growing number of global wind resource assessments have demonstrated that the world’s technical potential for wind energy exceeds current global electricity production, and that ample technical potential exists in most regions of the world to enable significant wind energy deployment relative to current levels. 

Wind energy, used by civilizations for thousands of years to grind grain and pump water using windmills, was reborn during the energy crisis of the 1970s when improvements in materials and technology made wind turbines more common. Today, windgenerated electricity is helping to provide for U.S. electrical needs. 

Wind energy is a form of solar energy. Wind is caused by the uneven heating of the atmosphere by the sun, variations in the earth's surface, and rotation of the earth. Mountains, bodies of water and vegetation influence wind flow patterns. Wind speeds vary based on geography, topography and season. As a result, there are some locations better suited for wind energy generation. Wind energy is a special form of kinetic energy in air as it flows. Wind energy can be either converted into electrical energy by power converting machines or directly used for pumpng water, sailing ships, or grinding gain.

Wind power is the fastest-growing source of electricity worldwide. The American Wind Energy Association estimates that more than $40 billion will be spent worldwide over the next decade to build new wind installations.

Wind energy is a universal resource. It can satisfy a multitude of global energy problems not only theoretically but also in actuality. It can be used to generate electricity, the leading source of energy of the twenty-first century. From the finite nature of fossil fuels, their geographically uneven distribution, and the resulting climate change due to its burning, to the dangers of the nuclear sector, recently experienced so dramatically in Fukushima, these problems are increasingly being answered through the generation of electricity by means of regenerative sources, especially with the use of wind energy.

Wind energy is a form of solar energy. Earth’s atmosphere is unevenly heated by solar radiation and the air is in constant motion to find equilibrium. Air is easily affected by pressure and temperature so methods of heat transfer such as convection, conduction, radiation, and advection relieve the temperature imbalances and are driving forces for wind. Wind is an intermittent source of energy with many factors affecting wind flow patterns, such as geological features of Earth’s surface, bodies of water, vegetation, and the Earth’s rotation.Wind is harvested through wind turbines, which generate electricity by converting the kinetic energy of the wind into mechanical energy.
