How Is Electricity Generated from Wind Energy?

1. The problem is: In point form, outline the process through which electricity is generated, highlighting the energy transformations that occur. Then state an advantage and disadvantage for this type of electricity production.
The attempt at a solution

I will be describing the energy transformations of wind energy.
· Wind power is the flow of air through wind turbines to generate electric power
· Heat energy is provided from the sun to warm the air
· Warm air rises while cold air sinks
· This results in a flow of air and forms wind
· This wind goes through a huge wind turbine and pushes its blades to transfer into kinetic energy
· The blades spin rotating oppositely charged magnets surrounded by copper wire and create electromagnetic energy
· This electromagnetic energy goes through a generator which transforms into electrical energy
· This electrical energy goes into our homes and powers our lights, ovens, etc.

Wind energy is very affordable; it is one of the most cost-effective energy sources today. It costs between 2 to 6 cents per kilowatt-hour. This is also a very clean energy source. It does not emit pollution into the air and does not cause health problems in humans. Unfortunately, the downside is that wind energy is not always dependable. We are never exactly sure just how much power can be generated every day, and there might not be enough to even power a city. Most places where there is a lot of wind is usually really far from the city.

Welcome to the PF.

Good job! I just have 2 suggestions for the parts I've bolded in your quoted text:

-1- The motion of the wind is already linear kinetic energy, and the turbine blades convert that into rotational kinetic energy.

-2- The "electromagnetic energy" from the turbine generator is already "electrical energy", but it does get converted into a form tht is compatible with the power grid (like 60Hz AC, for example).
