Small turbines are pointed by a simple wind vane, while large turbines generally use a wind sensor coupled with a servo motor.

Denmark is a pioneer in commercial wind power and produces half of the world s wind turbines.

For remote locations, solar panels or wind turbines could possibly be used.

There's massive P.V. arrays on the roofs as well as wind turbines.

These wind turbines can rotate in incredibly slow windspeeds, as a result.

Solar panels and wind turbines can provide off grid power in isolated rural areas.

When most people think of renewable energy sources, they imagine solar panels and wind turbines.

It is the first skyscraper in the world to integrate wind turbines into its design.

In some cases, Gülen finds that proponents of green jobs have not distinguished between construction jobs (building the wind turbines), which are temporary, and longer term operational jobs (keeping the wind turbines going), which are more permanent.

Not surprisingly, the leading Danish wind producer is today urging strong action on climate change that would imply even more sales of wind turbines.

Small wind turbines may be as small as a fifty watt generator for boat or caravan use.

Australia has installed wind turbines at Mawson Station as part of its renewable energy programme in Antarctica.

And you can power the entire U.S. vehicle fleet with 73,000 to 145,000 five megawatt wind turbines.

Deploying more wind turbines and solar panels creates a need for more builders, technicians, tradespeople, and specialist employees.

If you give me a 747, I'll make six megawatts, which is more than the largest wind turbines today.

For example, cutting a ton of CO2 with on shore wind turbines in Germany probably costs about 35, avoiding about 14 cents of climate damage per dollar. But offshore wind turbines cost about 150 per ton of CO2, avoiding just three cents of climate damage per dollar.

So turbines grew.

The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) defines small wind turbines as those smaller than or equal to 100 kilowatts.

For example, limits on the siting of wind turbines may well be motivated by legitimate concerns about the risks to wildlife, especially birds.

We see scary pictures of dry riverbeds (the result of global warming), along with plenty of pretty solutions like wind turbines and solar panels.

The wind turbines are expected to provide 11 to 15 of the towers' total power consumption, or approximately 1.1 to 1.3 GWh a year.

More importantly, planting forests is one of the least area efficient low tech ways to cut carbon. Solar cells and wind turbines require less than 1 of the area of forests to reduce CO2, they become increasingly efficient, and they can often be placed on non productive land (such as wind turbines at sea and solar panels in deserts).

This was confirmed by wind tunnel tests, which showed that the buildings create an S shaped flow, ensuring that any wind coming within a 45 angle to either side of the central axis will create a wind stream that remains perpendicular to the turbines.

Turbines equipped with advanced cooling.

You might take states like Iowa and Ohio two very important political states, by the way those two governors, and they would say, we're going to lead the nation in producing the wind turbines and the wind energy.

Accounting for a reduction of 50 Mt of CO2 per year, America s 30,000 wind turbines reduce emissions by just one tenth the amount that natural gas does.

A good illustration is Denmark, which early on provided huge subsidies for wind power, building thousands of inefficient turbines around the country from the 1980 s onwards.

At the end of 2012, 1,662 turbines at 55 offshore wind farms in 10 European countries are generating 18 TWh, which can power almost five million households.

In the past five years the industrialised skyline has been changed by the addition of large numbers of wind turbines taking advantage of the exposed coastal conditions.

300 MW of gas turbines

In addition to aircraft engines, Pratt Whitney manufactures gas turbines for industrial and power generation, and marine turbines.

Moreover, recent research by John Dabiri of Caltech suggests that vertical wind turbines may be placed much more closely together so long as an alternating pattern of rotation is created allowing blades of neighbouring turbines to move in the same direction as they approach one another.

Just floating.

During 2009, seven large wind turbines, likely Vestas 3MWs totalling 21MW capacity, were erected in the sea north of Sprogø to contribute to the electrical demand of the Great Belt Link.

Installing turbines which capture this movement, generates energy.

Feeling of weightlessness is interesting. Everything is floating. Floating is everything.
