It is crucial to develop and implement measures that balance the benefits of wind energy with the protection of bird populations.

The impact of wind turbines on bird populations

The impact of wind turbines on bird populations varies depending on various factors, including the location, design, and operation of the turbines. Some studies have found that wind turbines pose a relatively low risk to bird populations, with an estimated 214,000 to 368,000 bird fatalities per year in the US. However, other studies have suggested that this estimate could be much higher, with estimates ranging from 140,000 to 328,000 bird fatalities per year in Germany alone.

The factors that affect bird mortality

Several factors can influence the likelihood of bird collisions with wind turbines, including:

• The location of the wind turbines: Some locations may have a higher concentration of bird populations, making them more susceptible to collisions.
• The design and size of the wind turbines: Larger turbines with longer blades have a higher collision risk.
• The behavior and flight patterns of birds: Certain species of birds are more vulnerable to collisions than others, particularly those that fly at night or in low visibility conditions.
• The weather conditions: High winds or fog can increase the likelihood of bird collisions.
• The placement of wind turbines in relation to migration routes and nesting sites.

The measures being taken to protect birds

Wind energy is a clean and renewable energy source that has gained significant attention in recent years as a means of generating electricity. However, there are several challenges that must be addressed in order to effectively harness the power of the wind.

One of the main challenges of wind energy is the intermittent nature of the wind. Unlike traditional energy sources such as coal or natural gas, the wind is not a constant source of energy and can fluctuate significantly. This means that wind energy systems must be able to store excess energy when the wind is strong and release it when the wind is weak. This can be achieved through the use of battery storage systems or by integrating wind energy into a larger grid system.

Another challenge is the high upfront cost of wind energy projects. While the cost of wind energy has decreased significantly in recent years, it is still more expensive than traditional energy sources in many cases. This can make it difficult for governments and businesses to justify the investment in wind energy projects.

The location of wind energy projects can also be a challenge. In order to generate electricity from the wind, wind turbines must be placed in areas with high wind speeds. These areas are often located in remote locations, which can make it difficult to transmit the electricity generated by the wind turbines to population centers. Additionally, the visual impact of wind turbines can be controversial, and some people may object to their presence in certain areas.

Finally, wind energy is dependent on weather patterns, which can be difficult to predict. This can make it challenging for energy companies to accurately forecast the amount of electricity that will be generated by wind energy systems.

Despite these challenges, wind energy has the potential to play a significant role in meeting the world’s energy needs. With continued advancements in technology and the development of more efficient and cost-effective wind energy systems, it is likely that wind energy will become an increasingly important part of the global energy mix in the coming years.

Wind energy is a form of renewable energy that harnesses the power of the wind to generate electricity. It has become an increasingly popular choice for generating electricity, especially in areas with strong and consistent wind patterns.

The technology used to harness wind energy has evolved significantly over the years. The most common type of wind turbine consists of a tall tower with three blades that rotate when the wind blows. As the blades rotate, they turn a generator that produces electricity. The electricity is then transmitted to the grid and distributed to homes and businesses.

Wind energy has several advantages compared to other forms of energy generation. It is a clean and renewable source of energy that does not produce greenhouse gases or other pollutants. It is also a relatively inexpensive source of electricity, especially when compared to fossil fuels such as coal and natural gas.

One of the main challenges of wind energy is that it is dependent on weather conditions, specifically wind patterns. In order to generate electricity consistently, wind turbines must be located in areas with strong and consistent winds. This can be a challenge in some parts of the world, but advances in technology have made it possible to install wind turbines in a wider range of locations.

Another challenge is the visual impact of wind turbines. While some people find wind turbines to be an attractive and innovative source of energy, others may find them to be an eyesore. In order to address this issue, wind farm developers often work closely with local communities to ensure that wind turbines are located in areas that are not visually obtrusive.

Despite these challenges, wind energy has become a significant contributor to the global energy mix. According to the International Energy Agency, wind energy accounts for around 7% of the world’s electricity production. This figure is expected to continue to grow in the coming years as more countries adopt wind energy as a key component of their energy mix.

In addition to generating electricity, wind energy has a number of other applications. For example, wind energy can be used to power water pumps for irrigation, to power boats and ships, and to power off-grid homes and communities.

There are several different types of wind turbines, each of which is suited to different types of wind patterns and locations. The most common type of wind turbine is the horizontal-axis wind turbine, which consists of a tower with three blades that rotate around a horizontal axis. There are also vertical-axis wind turbines, which have blades that rotate around a vertical axis. These types of wind turbines are less common, but they are well-suited to locations with low wind speeds or turbulent winds.

In conclusion, wind energy is a clean, renewable, and increasingly important source of electricity. While it does have some challenges, such as its dependence on weather conditions and the potential for visual impact, these can be overcome with advances in technology and careful planning. As the world looks to transition to a more sustainable energy mix, wind energy will play a vital role in meeting our energy needs.

Due to continued distribution network instability and price inflation in the 3rd quarter of the year, wind industry giant Vestas has decreased its profitability estimates for 2022.

Despite raising the average retail price of its wind energy to €1 million/MW, the Danish manufacturer also reported a loss for the period.

In contrast to a €318 million profit a year earlier, it reported an operational loss (Ebit minus special items) of €127 million for the 3rd quarter. Additionally, it reported a third-quarter significant loss of €147 million after making a profit of €116 million the year prior.

The Q3 deficit was attributed by CEO Henrik Andersen on geopolitical uncertainties, rising inflation, and project delays that increased execution costs. He did, however, point out that Vestas’ service division had been stable during the period and that offshore wind had continued to gain pace, with Vestas winning preferred supplier status in the US, the UK, and Poland.

The manufacturer of turbines revised downward its financial prediction, now anticipating an operational loss for 2022 and an Ebit margin before exceptional items of roughly -5% as opposed to the -5% to 0 level it had earlier predicted.

“The energy crisis incentivizes a faster shift to an energy system built on renewables, and tangible result contracts like the US’s Inflation Reduction Act enhance the fundamental demand for renewable power solutions, but proposed project and order intake remain hampered by energy market uncertainties and red tape,” Andersen continued.

The third-quarter loss and projection revision from Vestas come amid ongoing supply chain issues and cost inflation pressures for manufacturers of wind turbines.

The third-quarter sales for the Danish powerhouse was €3.9 billion, a 29% decrease from the same period last year. According to CFO Hans Martin Smith, this decline in revenue was caused by fewer offshore installations, slower US activity, and “general delays.”

Between 1 July and 30 September, it received orders for roughly 1.9GW of turbines, providing the company with an order queue worth €18.1 billion at the conclusion of the time frame.

Vestas CEO Andersen remarked that in Q3 the average cost of its wind turbines increased to €1.07 million/MW, with the company charging €1.06 million/MW exclusively for onshore turbines. Vestas’ average selling cost per megawatt (MW) in the third quarter of 2021 was €810,000. According to CFO Smith, as previously announced price hikes for Vestas’ turbines went into effect, the company’s margin improved throughout the year.

As of September 30, 2022, Vestas additionally has service agreements with estimated contractual future income of €32.8 billion. The total backlog of orders, at €50.9 billion, is up 7.6% over last year.

However, Vestas revised its financial outlook for 2022 due to continued inflation, supply chain instability, and project delivery delays that increased expenses.

Vestas revised its prediction for sales from €14.5-16.0 billion to go along with its revised outlook for profit, now projecting an operating loss rather than the previous €14.5-16.0 billion.

Additionally, it now anticipates investing a total of around 850 million euros this year rather than the earlier expectation of about 1 billion.

Due to good performance and more repowering activities, the business now anticipates stronger revenue from service contracts – now projecting increase of at least 20%, versus 10% as previously announced. Andersen applauded Vestas’ service unit for delivering “stability” in the third quarter. It did, however, reduce the estimated Ebit profit before special items for service about 1%, to around 22%.

When something came to financial projections, Vestas conceded that there was “more uncertainty than usual.”
