Wind Energy Information

Enrique Said:

Does anyone know anything about wind energy?

We Answered:

Wind speed is measured (in knots) by the Beaufort Scale.

Renewable Energy - the most reliable source of renewable energy is water power, most especially tidal water power.

Here in London in Roman times and right into the early Industrial Revolution of the 18thC there were dozens of tide mills along the banks of the River Thames.
How did they work. A simple mechanism which allowed a massive wheel or set of wheels to rotate in the direction of the tidal flow and then to reverse as the tide in the River Thames changed direction. So efficient were these tide mills, that one, which still survives today, could be in continuous production of power to drive flour mill machinery for up to 16 hours per day.

Medieval tide mill found at Greenwich - where I live.

There is still one surviving windmill here in London, it dates from about 1800 and is at Brixton.

What are some examples of wind energy used in Virginia and the United States?

We Answered:

Suggest:
1- JMU center: http://vwec.cisat.JMU.edu

Their Center has good info & info on Va. projects
2- Google- so many sites to review

3- There are at leasr 2 projects being planned in Highland County and on nearby mountain ridges neat there. This region between Va. and West Va. is rated #5 category for wind potential- which is one of the highest for states east of Mississippi.

Wind Energy?

We Answered:

!) wind causes tubine to spinwhich drvies a dynamo inside which produces electricity

2)advantages - no carbon emissions, everlasting
disadvantages - need lots of turbines to be worth while, therefore lots of space, only works on a windy day
3)wind farms
4)Although wind currently produces just over 1% of world-wide electricity use, it accounts for approximately 19% of electricity production in Denmark, 9% in Spain and Portugal, and 6% in Germany and the Republic of Ireland

hope it helped =)

Information on Wind Energy?

We Answered:

Wind energy is extracted using sails (as for ships), wind generators, wind mills. Wind turbines are part of some of the above.

You could indirectly gather wind energy using machines that extract energy from waves.

The three links below should help with getting ideas.

Audrey Said:

Are there any government polices concerning wind energy?

We Answered:

I assume you're from the UK or US?

In the US: Look up wind's 'Production Tax Credit' or 'PTC'. This isn't a US gov't site but it might give you an idea where to look:

In the UK: Look up the 'Renewables Obligation Certificate' or 'ROC'.
