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 ...
Utilities managers use wind tunnels to test wind turbines used to generate electricity. Wind tunnels help make the turbines and their blades more efficient, effective and durable, so they can withstand constant, powerful gusts. But wind tunnels also help engineers determine wind farm layouts and ...
Wind turbines are only growing bigger as their demand increases, but how big can they get? Learn the answer in our informative guide.
How do monarch butterflies use magnetism? How do plants help in recharging groundwater? Why does Earth have a magnetic field? How does wind shear affect wind turbines? What are the effects of Earth's magnetic field on ocean features? Why does magnetic field strength decrease with distance?
Climate change is increasing the likelihood and frequency of extreme weather events and therefore the potential for outages (e.g., extreme cold causing wind turbines to freeze, solar panels breaking with hail). A number of projects are looking to invest in resilience (giving a ...
Alternatives include wind, solar, and biofuels. Wind power uses wind turbines to harness the power of the wind to create energy. Solar power uses the sun as an energy source, and biofuels use vegetable oils and animal fat as a power source. ...
Do larger or smaller propellers affect the amount of electricity produced? Try designing your own propeller. Experiment with multiple blades and blades at different angles. Which produces the most electricity at a given wind speed? Efficient turbines can harness wind energy and conserve energy from ...
