Wind Power Potential: Energy Output Explained

Wind power has become an important pillar of renewable energy production to power our growing societies in sustainable way. Recent growth in wind power is an impressive movement here worldwide. It's been driven by usuall reasons: technological advancement and more concern for environmental issues and promotion of sustainable energy. Latest statistics shows that wind power has become a significant percentage in the global energy mix. The installed capacity reached an astonishing new height each year. However, it is not exactly the same everywhere. A lot of elements will affect it including geographic locations, wind speeds, and governments renewable energy policy.

Wind power, moreover, depends on the turbine’s efficiency. Modern wind turbines, on average, have an average capacity factor (ie, how much energy is produced versus the theoretical maximum that can be produced by those specific wind turbines running at full power capacity 24 hours a day, 365 days a year) of 35 to 50%. For an energy resource whose variation is so central to production and whose economics are predicated on capturing a sizeable share of the ‘good” stuff, effective site selection for wind farms is of paramount importance. High-quality wind speed data, often obtained from historical weather stations, coupled to the latest modelling techniques, enables a prediction of the potential energy output. In other words, the ‘intermittency’ of wind energy – which, at first glance, might seem problematic in terms of energy conversion – at the end of the day it isn't. Below we cover why this is.

Improved wind turbine technology has helped to increase the energy production from wind turbines. Since the 1980s, wind turbine technology has evolved to better extract wind energy. A particularly important factor in the development of wind turbines concerns their rotor diameter and hub height, which have continuously increased, enabling larger turbines to generate more power, even in areas with slow wind speeds. Secondly, technological developments have increased wind turbine efficiency, which leads to a higher capacity factor and, ultimately, makes wind power much more competitive in the renewable energy market. Another innovation concerns the development of offshore wind energy.

Since more wind is available at sea than on land, wind turbines today are increasingly exploiting the high wind speeds and steady flow at sea. Additionally, innovations in materials science are also proving important, with lighter and stronger materials both enabling bigger blades, and also more efficient turbines. Digital technology is also an area of great progress, with predictive analytics and advanced monitoring all helping to improve the operational productivity and reliability of wind farms. These technological advances are increasing the energy produced by the same number of turbines, while also reducing the cost of energy production, and making wind increasingly competitive with fossil fuels compared with the early days of commercial wind farms. These advances are providing more and more evidence of ongoing product innovation within the wind turbine business. This is helping wind power to remain competitive, and will be essential to scaling up wind and other low-carbon energy sources in the coming decades.

The Economic and Environmental Impact of Wind Power

Indeed, wind energy is emerging as one of the most competitive renewable energy technologies in terms of cost, with average prices several times lower today than they were a decade ago. These cost reductions are accompanied by technological improvements, further driving down prices. The examples of ongoing efforts to improve the performance of wind turbines and address the mismatch between supply and demand of electricity through so-called ‘smart grids’ are just two examples. The turbines themselves are getting bigger, enabling economies of scale for the manufacturers. This in turn leads to leaner production, and the economies of scale impact the costs of installation and maintenance as well.

Because modern wind turbines generate electricity without emitting greenhouse gases or air pollution, they have a lower environmental footprint than most other forms of energy production – an important contribution to the global climate change mitigation effort to reduce our reliance on fossil fuels. Wind power is also comparatively benign with respect to the consumption of water: modern wind turbines consume essentially no water to produce electricity. Even in places with abundant water supplies, relying on other forms of energy production might mean indirectly consuming water required for irrigation, recreation, or consumption.

Challenges and Solutions in Wind Energy Production

The variability of wind poses a rather predictable problem: on days when wind speeds are low, wind farms will generate less energy, leading to renewable energy fluctuations in the overall energy supply. However, there are some promising solutions in the shape of technological developments in energy storage and grid operations. As battery storage systems continue to develop, surplus wind energy can be stored in batteries for distribution on those days when demand is especially high or on those days when wind speeds are low.

With batteries working in tandem with smart grid technologies, power grids can be stabilized and in concert with wind farms, energy outputs can become less variable and more reliable. A second challenge, on a longer timescale, is the integration of wind power into national and regional electrical grids and energy markets. This does not require technological breakthroughs, but rather smart policy and regulation that supports the integration of the energy production from renewables. For example, nation-wide policies such as feed-in tariffs and renewable portfolio standards will help to ensure that wind power is included in the energy production mix at the national level. Moreover, continued investment in grid infrastructure and integrations between regions will also enable the grid to handle the variability.
