What is Wind Energy? A source of energy that is driven by the force of wind. Wind is caused by huge convection currents in the Earth's atmosphere, driven by heat energy from the Sun. Wind energy is the fastest growing segment of all renewable energy sources. For hundreds of years, we have been using wind as a form of energy. Windmills have been used for pumping water

Renewability Wind is one of the easiest energy source to renew. This is because wind is naturally occurring every day. The best way to take advantage of the easily renewable nature of wind power as an energy source is to build turbines in places where wind occurs frequently. Turbines catch the wind's energy with their propeller- like blades. they can be connected to a utility power grid or even combined with a photovoltaic (solar cell) system.

Cost Due to improvements of wind turbines, the cost of wind energy has decreased. Wind energy is one of the most affordable energy resources in today’s economy. There was a decrease in cost of more than 90% since the early 1980's.

Pros to Wind Energy Free Never will run out Clean, non-polluting, electricity No air pollutants or greenhouse gases No fuel to purchase and minimal operating expenses.

Cons to Wind Energy Technology requires a higher initial investment than fossil-fueled generators. Lots of noise produced by the rotor blades. Birds and bats having been killed by flying into the rotors. Does not always blow when electricity is needed. Wind cannot be stored Good wind sites are often located in remote locations far from areas of electric power demand.

The Science Behind Wind Energy Wind energy is generated through the kinetic energy found in wind is converted into mechanical power Wind turbines are like airplane propellers that turn as wind pushes them which powers an electric generator that supplies an electric current The power generated in then stored in batteries for later use

Waste Products There are no waster products produced from wind energy Wind energy lowers greenhouse gas emissions

Uses of Wind Energy Wind energy is used by states/countries that can invest into it and have a good amount of wind to power cities/towns California Denmark Germany Wind energy has not been in widespread use because the land that wind turbines are put on can be used for farming which leads to choosing between what is more important – food or power
