Aenert news. Invention analysisIn previous comment dated 02/07/2022, we have provided a summarized review of "WIND ENERGY. Offshore Wind Turbine. Patent Database. June 2022" and basic statistical data from it. Now we will take a closer look at one of the important aspects of wind power plant operation. In recent years, there has been an increase in patenting activity in the field of technical...

For many centuries, people have tried to harness the power of wind to make everyday life easier and processes more efficient. The first constructions were called windmills and used for pumping water or grinding corn. In the 19th century, windmills were replaced by fossil fuel engines and a distributed power network. In the second half of the 20th century, a greater insight into aerodynamics and advanced materials, particularly...

The U.S. Energy Information Administration (EIA) recently published data on electricity generation in the U.S. for the first half of 2022. In our opinion, of particular interest is the data on wind generation, as the main area of renewable energy in the U.S. This is also relevant because of the growing global crisis in the fossil fuel energy sector. First of all, it should be noted that the share of renewables in U.S. power generation...

One of most important problems of wind energy is the relatively low capacity factor, which in real practice of wind turbines rarely exceeds 30%. As a result, huge material-intensive and expensive structures of wind turbines sit idle for a considerable time without generating electricity, reducing the investment attractiveness of the industry, hindering a decrease in selling prices for electricity and limiting the competitiveness of...

2021 was the most successful year ever for the offshore wind industry, according to the report released by GWEC (Global Wind Energy Council). 21.1 GW of new capacity was connected to the grid globally and stated global targets indicate that there could be more record years from 2025 onwards. China with 17 GW made up 80% of offshore wind capacity added worldwide in 2021, leading the world for the fourth year in a row. The remaining 20%...

One of the main barriers to the development of wind energy is its low capacity factor, which in real practice rarely exceeds 30%. The leading trends in the development of wind energy are the increase in the size of wind turbines and construction of wind farms in offshore zones, which allows the maximum capacity factor to be achieved. Thus, one of the largest offshore wind turbines – Haliade-X, developed by General Electric, have a...

Wind energy is without doubt one of the most important resources for achieving a cleaner and more sustainable energy industry. It is small wonder, therefore, that many countries around the world are continuously increasing their wind capacities to reduce the negative impacts of a fossil fuel-dependent energy industry. The US, for example, witnessed a significant growth in wind energy in 2020, according to the Office of Energy...

The Global Wind Report 2022 released by GWEC captures the resilience of the global wind energy industry, which experienced its second-largest year ever in 2021, down just 1.8% from a record 2020. The 93.6 GW of new installations in 2021 brought the total global wind power capacity to 837 GW, showing a 12% growth for the year. Of the 93.6 GW of new installations in 2021 worldwide, the onshore wind market added 72.5 GW. Europe, Latin...

With the number of wind power installations increasing around the globe every year, utilising spent material, such as blade debris, is turning into one of the most challenging issues of modern wind industry. A study conducted by the University of Cambridge found that 43 million tonnes of wind turbine blade waste are likely to be generated by 2050, most of which will be disposed of in landfills. 40 per cent of this kind of waste is...

In its press-release to the Global Offshore Wind Report 2021, the Global Wind Energy Council (GWEC) looks at the growth of the global offshore wind industry in 2020, presenting a forecast of the latest technology trends and innovations, and discussing the challenges and opportunities for offshore wind market growth toward meeting global climate goals.  In 2020, the offshore wind market volume reached 6.1 GW, which is slightly...
