Staticnotes4u Wind energy is obtained from the kinetic energy of moving air and is converted into electrical energy using wind turbines. The available wind power depends on air density, wind speed, and the swept area of the turbine. Derive an expression for the power available in the wind for conversion by a wind turbine. Also, derive … Read more
Classify different types of wind turbines with examples. Wind turbines are mainly classified as follows: 1. Based on axis of rotation: 2. Based on location: 3. Based on size: Detailed Explanation of Types of Wind Turbines Wind turbines can be grouped into different categories depending on their construction and application. The main classifications are given … Read more
Compare vertical axis and horizontal axis wind turbine. Point HAWT (Horizontal Axis Wind Turbine) VAWT (Vertical Axis Wind Turbine) Axis Orientation Rotor shaft is horizontal (parallel to ground) Rotor shaft is vertical (perpendicular to ground) Location of Components Generator & gearbox placed at top (nacelle) Main components placed near ground level Wind Direction Needs yaw … Read more
What is vertical-axis wind turbine? A Vertical Axis Wind Turbine (VAWT) is a type of wind turbine in which the main rotor shaft is vertical (perpendicular to the ground). The generator, nacelle, and other main components are placed near the ground, so a large tower is not required and maintenance becomes easier. It can capture … Read more
With a neat sketch explain the functions of the main components of a HAWT. Functions of Main Components of a HAWT Detailed Explanation of Horizontal Axis Wind Turbine (HAWT) Components: Think of a Horizontal Axis Wind Turbine (HAWT) as a massive, high-tech windmill designed for the 21st century. It’s not just a set of spinning … Read more

Measurement of solar radiation using pyranometer is an important method used in solar energy. A pyranometer is a device that measures solar radiation.
A solar map of India shows how much sunlight energy different regions receive throughout the year. This energy is called solar radiation.
Solar radiation geometry explains how the Sun’s position changes relative to the Earth and a receiving surface like a solar panel.
A single line diagram (SLD) of an electric power system is a simple drawing that shows how electricity flows from the generating station to the final consumer.
