25.04.2023

Aenert news. Energy Market & Energy StatisticsIRENA presented statistics on renewable energy over the past decade and developments in 2022. Total renewable generation capacity increased by 9.6% (+295 GW) in 2022. Solar and wind energy accounted for 90% of the net increase in renewable energy sources, with solar power continuing to lead in capacity growth: its increase was 192 GW (+22%), followed by wind power –...

GWEC Global Wind Report 2023: third-best year in the wind industry

14.04.2023

Aenert news. Energy Market & Energy StatisticsThe GWEC Global Wind Report 2023 states that global commitment to renewable energy is stronger than ever, even though 78 GW of new wind power capacity in 2022 is the lowest in three years, but still the third highest in history. In addition, based on market analysis and policy measures in different countries, experts predict that wind energy installations will...

European Electricity Review 2023: Wind and Solar Generated More than Gas for the First Time

17.02.2023

Aenert news. Energy Market & Energy StatisticsEMBER's seventh annual European Electricity Review 2023 (CC BY-SA 4.0) analyzes the EU-27's progress in the transition from fossil fuels to clean power, providing data on electricity generation and demand in 2022 and making a forecast for 2023. In general, EМBER records an acceleration of the electricity transition in 2022, not least because of Russia's invasion of...

New Type of Blade to Revolutionise Wind Energy

06.11.2022

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...

US Wind electricity net generation, Jan-Jun 2022

19.10.2022

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...

Offshore wind turbines. Maintenance, repair, replacement. Recent Patents

22.08.2022

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...

GLOBAL OFFSHORE WIND REPORT 2022: a new record in offshore wind industry!

14.07.2022

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%...

WIND ENERGY. Offshore Wind Turbine. Invention analysis

02.07.2022

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...
