wind power is a wonderfull way to get more high power energy

[vidya12]

A wind turbine is a rotating machine which converts the kinetic energy in wind into mechanical energy. If the mechanical energy is used directly by machinery, as like a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator, wind turbine, wind power,
wind power is a wonderfull way to get more high power energy

It are not affected by the direction of the wind, which is useful in areas where the wind changes direction frequently and quickly. Unlike traditional horizontal axis wind turbines, a yaw mechanism is not needed to turn the wind turbine towards the wind.it are better able to harvest turbulent air flow found around buildings and other structures
wind turbine are ideal for both rural and urban applications, including roof top installations. Depending on the shape of the roof, the wind flow over the roof can be concentrated, leading to an increased energy output

Wind energy has always intrigued me...

When Wind flows into say a billboard. Does that Billboard reduce the wind energy very much (stress / heat) or does it mainly re-direct it?

When Wind flows into a Turbine... How much of the energy is stripped and converted to electricity v.s. dissipated into the obstacle as stress / heat....

When "energy" is removed from the environment (air) in this case, what are the theoretical effects (large scale?)

I'm not sure it would be harvestable in a large enough scale to make a perceivable impact, but there's always butterfly effect.

Just a curiosity I guess. Too complicated to model or truly understand.

Actually, wind farms go through an extensive resource assessment and design process before they are built. Banks insist on it before they lend money.

There is an entire science devoted to fluid dynamics and flow models. These models are used for identifying turbulence and unusual wind conditions around buildings and terrain. I suspect you'd find some interesting stuff if you entered wind farm modeling in Google.

Wind is the best short-term clean energy source. Solar is the ultimate answer but solar economics, especially PV, still have a way to go. I think Chu, the new Energy Secretary, said a factor of 4 or 5 improvement. Wind, on the other hand, is competitive now with the so-called clean coal which no one can define, much less put a price tag on. It doesn't really exist.

Now if we could only manufacture more of the wind turbine parts here in the USA . . .

Actually - What may be a better approach then either wind or solar, could be Geothermal. Using the process posted in the "everything else" section here:

http://gm-volt.com/forum/showthread.php?t=2876

Basically geothermal converts heat into electricty. Apparently more energy is generated then it consumed to extract it. (using compressors)

In a way you could consider this solar, but then again, you could consider wind energy solar as well.

An interesting read anyhow.

Wind energy is certainly solar powered, as is hydroelectric. Take away the sun, and these sources of energy go away.

Geothermal energy is powered by heat from beneath the surface of the earth, which is thought to be generated by decay of radioactive materials (nuclear power) and effects of gravitational forces.

Because turbine parts are so large (e.g., blades), they are most economically manufactured near where they will be deployed. This is similar to cement. Heavy, bulky products are expensive to transport. Do you think the concrete for the foundation of a wind turbine will be shipped from China? Have you checked out shipping costs for a turbine blade that is 150 feet long? Here's a hint - don't plan on taking many corners! Can you build and maintain a wind turbine remotely from China?

Interesting that we lost our leadership in wind energy to Europe. Now, the leaders - Vestas, Siemens, Acciona - are locating manufacturing plants in the U.S. The U.S. isn't importing wind turbines because we aren't competitive in manufacturing. We are importing wind turbine components because of Ronald Reagan and the Republican anti-environmental agenda.

The key to wind is the Renewable Energy Standard currently being advocated by our "Democrat Socialist" party - btw, the only party that actually cares about something other than tax cuts for the very rich. When states have passed enforceable "renewable portfolio standards", investment has followed.

Again, government policy is the solution. Do you think you can rely on the coal, oil, and utility industries to figure out renewable energy? This is kind of like the Big Three figuring out how to build quality cars or how to have economical cars in case gas prices hit $4.00/gallon. No chance at all.

Why would anyone count on the coal industry to figure out wind power? Or the oil industry? It's not their job.

My Chevy truck is a quality vehicle and I've driven them all.

I'd agree with you that Detroit has not been adept at understanding oil price trends. The Volt, for now, seems to be as forward-thinking as it gets (with all due respect to Tesla).

I hope I get the chance to be first in line to buy one.

Coal companies and oil companies are fighting wind with millions and millions of dollars of disinformation. Oil companies are now touting the jobs the create (I assume they are referring to minimum wage jobs pumping gas). The last thing Big Oil wants is electric cars and renewable electricity. How can you ignore a $trillion industry with unlimited capacity to fund disinformation?

Coal companies are claiming to be "clean" except there isn't one "clean coal" plant in existence anywhere. Coal is an environmental disaster - carbon heavy, sludge, ripping off mountain tops, and polluting streams. Been to West Virginia to see where coal is mined?

Utilities are among the biggest naysayers (kind of like IBMers denying that mainframes will become dinosaurs or GM not considering the impact of $4/gallon gas). Utilities refuse to admit that wind can account for significant generation and they publish their own disinformation about "what happens when the wind doesn't blow." Fact is, when we have an efficient and reliable grid, the wind will always be blowing somewhere.
