Are Wind Turbines Beneficial Or Hazardous?
Article by Eric Meier
Nearly everybody knows what a wind turbine is and how they produce energy, but for those who don’t know I will explain. A regular wind turbine is a tall tower that has blades connected to a rotor. Any time the wind blows the generator the blades make the rotor rotate and the movement of the rotor forces the generator within the turbine generate power. Inside the generator are many magnets and loads of copper wire, which generates electricity. There’s almost nothing difficult about this type of generator.
Wind turbines, as the name shows, necessitates wind to function. The reason why turbines are built so tall is to take advantage of the stronger winds found at higher altitudes. This height makes it possible for the rotor to obtain more exposure to the wind and therefore create far more electricity. All of this would not matter if there was no wind from the beginning. Historical weather information is carefully analyzed to choose sites that will supply sufficient steady winds for the turbines. This tends to mean they are situated along coastlines where it is usually very windy. Although wind speed is the most crucial variable to measure, wind direction may also have an impact on the performance of the installation. A time tested model, adapted from the initial wind powered water pumps, uses a tall fin to point the propeller directly into the wind, regardless of the direction it emanates from.
Wind turbines can produce quite a lot of energy; one turbine may generate electricity for one house, or maybe they can be used to power machinery which in turn does something like grinding wheat. A battery backup that is replenished by the turbines, supplies power during instances when no wind blows. As a result of the high initial investment, which will require decades to recover, wind turbines require a long-term perspective. A positive aspect of these turbines, compared to solar panels, is they do not require sunlight. Solar panels can not work in the dark however wind turbines can. Another great thing about wind turbines is that they’re eco-friendly as they produce zero pollution. More turbines could reduce the causes of global warming that threaten the planet nowadays. The energy source is also renewable, just like solar energy, because there is always wind blowing. This suggests that turbines will usually be able to produce energy if they are located in high wind areas.
As with just about anything there are some disadvantages of using wind turbines for energy. Many individuals don’t want to be observing a tall tower with a propeller on the top outside their window. Large installations, with a good deal, or even hundreds grouped together, produce visual pollution in coastal areas, as reported by critics. Like any mechanical gadget that moves, they might be quite noisy. Wildlife enthusiasts complain that birds and bats are damaged by them. Bats specifically are susceptible, due to the fact their sonar system is disrupted by the rapid circulation in the air. While these occurrences are rarely noted they do take place.
Wind turbines surely seem to be a good source of energy, but obviously there are downsides like with anything. Wind turbines offer great promise for generating clean, renewable and safe energy, with couple of serious downsides.
