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.Know More
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
According to the Department of Energy, wind turbines generate electricity when the wind moves the fan blades, which are connected to an electric generator via a central shaft. As the blades turn, they turn the generator, creating an electric current.Full Answer >
Most parts of the world have standardized their electricity supply systems to either 60 hertz (U.S. and most of the Americas) or 50 hertz (Europe and most of Asia). This refers to the number of times per second that alternating current reverses direction.Full Answer >
According to the Occupational Safety & Health Administration, electricity is dangerous because it can cause burns, nerve damage, cardiac arrest and death. Alliant Engery also notes that the majority of the human body is composed of water, which makes it a good conductor of electricity.Full Answer >
The abbreviation "mA" denotes the International System unit for electrical current known as the milliampere. One milliampere is equal to one-thousandth of an ampere. The unit is named for the 18th and 19th century French physicist Andre-Marie Ampere, who studied electromagnetism.Full Answer >
