Wind Turbines Pros And Cons
One such source is wind energy – which has the capability of resolving power crisis of the entire world if tapped to its full potential. Add to it the fact that it is much more environment friendly as compared to the fossil fuels and wind energy comes up as one of the best alternative source of energy. But is everything really so simple? Can we harness the entire potential of this force of nature? Is it possible to erect wind turbines without disturbing the balance in environment? We decided to assess wind turbines pros and cons in a bid to answer these very questions and the results were quite promising.
What are the Pros and Cons of Wind Turbines?
On the basis of their design, wind turbines are divided into two types – horizontal axis wind turbines and vertical axis wind turbines. At the same time, it is also possible to classify them in two different types on the basis of their location. These two types of wind turbines include onshore turbines (those located on land) and offshore turbines (those located in oceans). Irrespective of whether you develop onshore wind turbines or offshore wind turbines, pros and cons of the same are bound to be there. Offshore turbines, however, have an added advantage as wind speed on ocean surface is better as compared to the same on land. Given below are various advantages and disadvantages of wind energy development with the help of wind turbines.
Wind Turbines Pros
There are several advantages of wind power on the basis of which it is pitched to be the future of energy revolution. The most prominent advantage of wind turbines is that they do not pollute the environment like the carbon-based fuels do. Similarly, wind turbines do not generate radioactive waste like nuclear power plants do. While the main drawback of conventional sources of energy is that they are exhaustible, wind energy is not subjected to any such problem. Wind turbines cost also works in favor of this source of power as the investment incurred on development and operation of these turbines is earned back within 3 months of operation. More importantly, the raw material in this case i.e. the wind, comes absolutely free of cost and the only investment incurred is on development of infrastructure and operation. Flexibility is yet another plus point of this power source as you can develop energy required to power a single house using one win turbine or develop energy for entire region by building a wind farm. Decommissioning of wind turbines is also quite easy as compared to that of other power sources.
Wind Turbines Cons
As in case of various other alternative sources of energy, even wind turbines have their own drawbacks. One of the most prominent drawback that the critics cite when it comes to wind energy development is the lack of efficiency. While wind turbines do generate decent amount of power, that is by no means comparable to the amount of electricity produced by a single nuclear power plant. That invariably means that a large number of wind turbines will be required to meet the energy demands, which again calls for a significant investment.
More importantly, these structures are also vulnerable to the extremities of the weather. Fast blowing winds can bring down the blades of these turbines, if not the entire turbine itself. Some critics and environmentalists also point out that wind turbines kill birds and bats, which again questions its environment friendly attribute. Even though wind power pros and cons make it look quite impressive, administrators are skeptical about investing in the same owing to these very drawbacks of wind turbines development.
Weighing wind turbines pros and cons reveals that its pros have a slight advantage over its cons. A look at wind energy pros and cons on paper may make this source of power seem quite promising, but ground reality is something that has to be paid more attention to. There is absolutely no doubt about the fact that wind energy is an environment friendly and renewable energy source. But then, is it worth to invest so much in developing wind turbines or should we opt for other more efficient methods of generating electricity. At the end of the day, we are left with no option but to sacrifice on something. The onus is on us to decide whether we are ready to sacrifice on efficiency or the environmental benefits.
Electricity Saving Tips That Give You Lower Electric Bills
Tip A: Turn off entertainment appliances and devices when not in use.
One of the most important ways to save electricity at home is to completely turn off TVs, home theater systems, and so on, when they’re not in use, or when you’re done using them. Leaving them in stand by mode is not enough, especially because appliances that are in standby mode still use up power, thus, if you want lower electric bills, turn electrical units off totally. In the event that you and your household members frequently forget to do this, you may opt to purchase a device that cuts off energy to all machines and appliances that are in stand-by mode.
Tip B: Prefer CFL bulbs over incandescent bulbs.
Part of electricity saving tips that is a recommended solution to the dilemma of how to conserve electricity is this: use CFLs instead of incandescent light bulbs. This is because CFLs are definitely more energy efficient than the incandescent ones. You’ll be able to save a big energy consumption percentage when you replace all incandescent with CFLs.
Tip C: Use non electrical stuff as much as possible.
Included in the list of ways to save electricity is for you to refrain from using electrical devices such as electric stoves, electric kettles, etc. They have non electric counterparts that work well after all, so if you yearn to have lower electric bills, why not use non-electric stuff more often? One of the vital electricity saving tips that you should follow, for example, is this: heat water in a normal kettle, rather than in an electric water kettle. When heating food, instead of using a microwave which uses up a lot of energy, why not heat food in a cooking pan on a gas stove?
Tip D: Air dry clothes as much as possible.
Another good answer to the question of how to conserve electricity is to avoid using the spin dryer or the tumble dryer for drying clothes. When the weather is good and the sun is shining, you’ll get lower electric bills when you hang the clothes outside to dry. There’s nothing wrong with using electric dryers during rainy season, but during the spring and summer months, you’ll be able to conserve electricity and see a decrease in power bills when you dry clothes by natural air and under the sun’s warmth.
Tip E: Invest in energy efficient appliances.
Right now there are so many appliances and electrical devices that have the Energy Star label on them, which means that they are energy-efficient. Of course, included in the list of electricity saving tips is for people to sell their old appliances and start purchasing energy-efficient ones that are sure to bring significantly lower electric bills compared to when they used appliances that have no Energy star ratings.
There are so many ways to save electricity. The challenge is if you and your household members will be disciplined enough to stick to them regularly, without lapse. Learning how to conserve electricity is no use if you don’t really apply what you’ve learned. Aside from following these electricity saving tips, people can also choose to rely on solar energy to power up their home. This e-book: Understanding And Installing Your Own Solar Electric System, will not only share energy conservation tips to readers, but will also guide them through the process of building solar electric systems for the home.
