What is a windmill: The term wind energy or wind power describe the process through which wind turbines convert the kinetic energy in the wind into electrical energy by the use of generator.
Vertical-axis wind turbines (left: Darrieus turbine) In a VAWT, the shaft is mounted on a vertical axis, perpendicular to the ground. VAWTs are always aligned with the wind, unlike their horizontal-axis counterparts, so there's no adjustment necessary when the wind direction changes; but a ...
Wind turbines are seen in this undated stock photo. STOCK PHOTO/Adobe Stock The analysis found that as the proportion of renewable energy in the grid increases, the intensity of blackouts -- measured by the number of affected customers and the length of outages -- decreases. This findi...
How do convection currents work? Explain how convection currents are produced in the air. How does the tropopause cause wind shear? How does wind shear create eddies? How does wind erosion gets its energy? How does wind shear affect wind turbines?
in bursting landfills. And whilst our instinct might be to demonise the material itself, arguably the main problem is how we use it. But first, it’s worth remembering what a versatile and useful material plastic is, making...

One of the fastest-growing sources of energy, wind turbines generate electricity without emitting greenhouse gases into the environment (unlike fossil fuels). But how do wind turbines work?
Wind turbines in Greece set a national record on September 6, accounting for 81 percent of the country's electricity output. High temperatures, wildfires and flooding pretty much sum up the weather patterns in Greece since the summer. From an unprecedented amount of rain in...
To avoid the worst impacts of climate change, we need to stop digging up fossil fuels. But the switch to renewables doesn’t mean we stop digging altogether. Wind turbines contain literal tons of copper and iron. Batteries for electric vehicles contain lithium, cobalt and nickel. All those ma...
