Wind energy is important because it holds immense potential in supplying electricity across the world. Unlike other sources of electricity that require fuel in processing plants, wind energy generates electricity through wind, which is free. Wind is considered a native fuel that does not need to be transported or mined, eliminating two costly expenses from long-term energy expenses.Continue Reading
The costs of mining and transporting fossil fuels and nuclear power are highly variable, and the cost of electricity from these sources often fluctuates. Many experts consider wind power a viable alternative to buffer these costs because wind is fixed and free. The use of wind-generated electricity promotes cost-effective and renewable production of energy. Moreover, it reduces dependence on fossil fuel.
The benefits of wind energy are numerous. Wind energy is home grown, and local landowners and small businesses can operate single turbines or clusters of turbines. It doesn't emit contaminants into lakes and streams, and it doesn't produce hazardous airborne pollutants. Wind energy doesn't cause acid rain or contribute to global climate change. Most other sources of power, including natural gas and coal, produce greenhouse gases, whereas wind energy produces none. Wind energy has a minimal impact on crop production and livestock grazing as well, because wind farms cover only small areas of land.Learn more about Electricity
Wind turbines generate energy when their three long blades rotate in the wind, turning a generator to produce electricity. One large turbine generates enough energy for over 500 homes. The largest wind turbines are equal in size to a 20-story building, with blades that are nearly 200 feet long.Full Answer >
Wind energy is created when moving air causes a wind turbine to rotate, powering a motor that generates electricity. The energy of the wind itself derives from differential heating of the air by the sun and the rotation of the Earth, combined with landscape features which shape the air flow. In this way, wind power is an indirect form of solar power.Full Answer >
Electromotive force is the difference in electrical potential between two points that compels electricity to flow to an area of lower potential in order to equalize charge. According to the HyperPhysics website, the force is measured in volts and frequently abbreviated as "emf."Full Answer >
Some fun electricity facts for kids are electricity travels at the speed of light, it always tries to find the easiest path to ground and it can be produced from wind, water, the sun and even animal feces. Also, two like charges repel each other, while opposite charges attract each other.Full Answer >
