How Does a Wind Turbine Work? What Are Its Components?

wind turbines

The way a wind turbine works is the opposite of a rotating motor. While in a motor, the energy is consumed, but in a wind turbine that energy is generated in the form of electricity from rotating blades. Including wind, in most other technologies  (non-renewable and renewable), rotating generators are the main electricity generation component, […]

What is BETZ limit for Wind Turbine Efficiency?

Betz Limit or Betz Law is the theoretical maximum efficiency for a wind turbine, that is 59.3%.

The Betz limit is the theoretical maximum efficiency for a wind turbine, calculated by German physicist Albert Betz back in 1919 [1]. Betz calculations showed that this value is 59.3%, which allowing at most only 59.3% of the wind kinetic energy to spin the turbine and generate electricity. In reality, turbines cannot reach the Betz […]

What is wind class in wind turbine?

Wind Class of a wind turbine (WTG) tells you what kind of turbine fits the “normal wind conditions” in a specific location.

Wondering what a wind turbine Wind Class is? Well here you should be able to find a quick answer. This WTG (Wind Turbine Gnerator) classification tells you what kind of turbine fits the “normal wind conditions” in the location that you are planning to install the wind turbine / have a Wind Park. Studying the […]

Energy self-sustainability in Europe, short-term strategies: Energy efficiency

Energy Efficiency - Cheapest, Safest, & Cleanest Energy Measure ...

Europe is facing all-time high gas and electricity prices these days [1]. It affects from top to toe the whole economy and the life quality of European citizens. Instead of discussing the five proposals of the European Commission (EC) president [2], we are going to discuss the short-term and mid-term strategies to improve energy self-sustainability […]

Global Wind Energy Installation in 2021 at a Glance and Market Outlook up to 2026

Global Wind Energy Installation in 2021 at a Glance and Market Outlook up to 2026

Introduction Despite the COVID-19 pandemic, 2021 was a fantastic year for renewable energy installations. There was a 9.1% increase in renewable energy addition in that year over 2020. The biggest slice was grabbed by solar energy with 133 GW [1], followed by around 93.6 GW of wind energy [2] and 19 GW of hydropower. According […]

The Largest Offshore Wind Farm in the World with More than 1200 MW Capacity

The Largest Offshore Wind Farm in the World with More than 1200 MW Capacity

2021 was a brilliant year for renewable energy installation, especially wind energy despite the second year of the COVID-19 pandemic. The wind industry has enjoyed its second-best year ever, in 2021 after 2020’s record, 95.3 GW [1]. Although the onshore wind has the leading role in the wind energy market, offshore wind has had a […]

Introducing Some of Wind Turbine Generator’s Technical Specifications

Introducing Some of Wind Turbine Generator’s Technical Specifications

Introduction to wind turbine generators Wind turbine Generators work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity [1]. In a wind turbine generator, propeller-like blades spin around a rotor, spinning a generator, which creates electricity. As the wind blows across the rotor blades, a […]

Why Have Wind Turbines Been Designed With Three Blades, No More No Less?

Why Have Wind Turbines Been Designed With Three Blades, No More No Less?

For centuries, human beings, the wind has been an important source of energy, from sailboats to windmills. As a sustainable alternative to fossil fuels, wind power has gained popularity in recent years. Wind farms have started dotting coastlines, and deserts across the world, and by now you’ve probably noticed their distinct wind turbine design [1]. […]
