Wind turbines rotate in a circle in the wind and generate electricity
By using windturbines
Rarely, but it has happened before if there are strong winds and the blades fail to feather.
A windfarm would cost alot depending on how many windturbines you buy. Where you build your windfarm , is the purpose of how much you will pay.

No, a wind turbine is a single structure that converts wind energy into electricity, while a wind farm is a collection of multiple wind turbines grouped together in a specific location to generate electricity on a larger scale.

in an area that is windy because if it isn't the wind turbine will just go off energy not windA2: Choose a location you own or can lease, that is close to your house or the grid where you can sell the energy to. You want the site to be as windy as possible, with consistent winds. You want to survey the wind to see what the maximum winds are but most importantly how consistent they are. This will help you design it. People always make sure wind turbines can handle the maximum winds, but how much power will it produce over the year? Probably higher in winter and lower in summer. But I would guess even if you choose a windy place you might only get 12 percent of your rated capacity. A local power station has a 600 KW system but it only produces 72 kw on the average per year based on 13 years of service. They could have chosen a better site and they did when they purchased 10 new 2.4 MW wind energy systems this year.To summarize: You want to choose a location based on your Wind Survey. Find out the site which is most convient to you that produces the most energy per year for you.
Alternative energy sources can decrease cost by reducing the reliance on expensive traditional fuel sources (like oil and gas), which can be subject to price fluctuations and supply constraints. Renewable energy sources also have lower operating and maintenance costs once the infrastructure is in place, making them more cost-effective in the long run. Additionally, alternative energy technologies are becoming more efficient and cost-competitive as advancements continue to be made in the industry.
well the total consumption of earths power on average sofar a year is 15TerraWatts of power, although this increases each year. the average output per year for 1 turbine is 0.35MegaWatts so that would mean, roughly 45000000 (fouty five million) wind turbines could more than power earths entirety (43Million is more than enough) even with 43 million there would be lots going to waist. Now the total cost of all this would be 460trillion dollars, which is not that much. it would be affordable if 10 or 20 of the worlds most wealthiest countries, gave a decent wack of money from their annual incomes (not that much tho) so like 25 of countries gave a 20 trillion dollar donation. (they make way more each year. its affordable, and will give too many benefits for it to be a rip off. -Ignore above. the 2000 gross world product was ~44 trillion. 460 trillion is more than all the world has. I've seen the 15 terawatt figure as well, so this may be a reasonable figure. A good sized land-based wind turbine today has a rating of 3MW, and a good power factor of 35% - so you can estimate an average turbine as being able to produce 3MW x .35 = 1.05MW constantly. Do the math and you end up with needing approximately 14.25 million good sized wind turbines. Actual cost cannot be calculated by this number. Significant upgrades to power infastructure is necessary to even begin to think about this sort of thing. Also, Virtually every power plant now in existence would need to be scrapped and replaced with large fast start type units. The amount of land needed and people to take care of such a system is staggering. Remember power production in and of itself does not provide any useful goods - this would simply increase the cost of power, which would decrease the amount of real goods produced from that power, and in the end bankrupt the world. just letting you know, America by itself spends atleast 20 trillion a year on war related stuff.14.35 million turbines might cost 120-171trillion(that's a retail price) you might be able to do it for 10-12trillion. and there is more than 460trillion on whole earth, Donald trump and bill gates and the late Micheal Jackson had atleast 15trillion (Micheal 5-10) each so that's, atleast 40trillion between 3 people, what about all the casinos. cocacola amitil make 500billion+ a yea. i think the total gross is not acurate to be honest, people are likely to hide money, and not many people are honest (especially rich people) on incomes there are parts of the earth that produce constant wind speeds of 150km/hour, putting a decent windfarm there would produce 75TerraWatts easily
