How can windmills create electricity if they're so often moving slowly .

Sep 20, 2011 . But if the wind speed doubles, then a windmill could produce eight times more power under the appropriate conditions. . A gear system increases the original rotational speed of the blades to the high speed needed to generate electricity, converting the mechanical movement of the blades into power.

Notes and queries: Why do wind turbines always have three blades .

Sep 6, 2011 . Why do wind turbines have only three blades? Wouldn't four be more effective? Like many design considerations, the number of blades on a wind turbine is a compromise. Each blade disturbs the air for the following blade, so ideally you want as few blades as possible to maximise efficiency. You need to.

Wind Energy - The NEED Project

The moving air is wind. As long as the sun shines, there will be winds on the Earth. We will never run out of wind energy. It is a renewable energy source. It is also free, since no one can own the sun or the air. Some places have more wind than others. Areas near the water usually have a lot of wind. Flat land and mountain.

Why Wind Power Doesn't Work - Forbes

Jan 20, 2012 . The thing is, any system which costs more than $80 (about €65) per tonne CO2 not emitted doesn't work. Therefore wind power doesn't work as a climate change mitigation strategy. OK, so I'm going to have to back up and explain a few things here. This study looks only at the energy infrastructure in NW.

Commonly Asked Questions About Wind Energy | We Energies

Wind traveling across the blades creates lift — like an airplane wing — which drives a generator producing electricity. Electricity generated by utility-scale wind turbines is sent to the electric transmission system, where it displaces electricity that would otherwise have been generated by more traditional sources such as coal,.

How Much Wind Does a Wind Turbine Need? | UNC-TV: Science

Most of what you would call large-scale wind turbines typically start turning in winds of seven to nine miles per hour. Their top speeds are around 50-55 mph, which is their upper safety limit. Large-scale wind turbines normally have a braking system that kicks in around 55 mph to prevent damage to the blades. Ironically.
