Alternate Power DIY

The quest to find a replacement for carbon-based fuels that we have been using all this while has intensified with the entire world heading towards a severe energy crisis. There do exist quite a few options in form of alternative energy sources on the horizon, but choosing the best among them is a bit difficult with all of them having their own 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.

Geothermal energy is the energy which is derived by harnessing geothermal dry steam or hot water that is found beneath the Earth’s crust. One of the lesser known geothermal energy facts is that there exist three different types of geothermal plants – dry steam plants wherein the steam is directly brought to the plant by the means of pipes, flash steam plants wherein hot water is brought to the plants through pipes and steam is created inside the plant, and binary cycle plants wherein hot water found beneath the Earth’s crust is mixed with some chemicals to form steam. The steam that is created is eventually used to rotate the turbines in order to produce electricity. The process by which geothermal energy works is almost same in each of these types of plant, the only difference lies in the process by which steam is created. In a bid to find out whether this source of energy is really efficient or not, we decided to assess geothermal energy advantages and disadvantages, and come up with the following reasons.

Geothermal Energy Advantages and Disadvantages

Most of the sources of energy available today have their own pros and cons, and geothermal energy is no exception. With so many intricacies involved in the process of geothermal heating – advantages and disadvantages of the process are ought to be there. Given below are the details of geothermal energy pros and cons which have to be taken into consideration before coming to a conclusion as to whether this source of energy can replace its carbon based counterparts or not.

Geothermal Energy Advantages

A look at geothermal energy and its advantages reveals that this form of energy is backed by enough reasons for us to shift bases from fossil fuels to this environment friendly source of energy. The fact that geothermal energy doesn’t rely on burning of fossil fuels only means that it is less pollutant as compared to its counterparts which rely on fossil fuels. The plants in which geothermal energy is produced are as environment friendly as the energy in itself. When it comes to this source of energy, we don’t have to worry that it will get exhausted anytime soon. As long as heat is generated continuously beneath the surface of the Earth we can harness the steam produced by it and generate power. Geothermal energy cost which is quite low is yet another advantage that this source of energy has on other sources which boast of efficiency.

Geothermal Energy Disadvantages

There do exist quite a few disadvantages of geothermal energy. The foremost issue which needs to be addressed here is availability. Even though hot water and steam is found beneath the Earth’s crust in copious amounts, the regions from where it can be actually tapped are very few. It is very difficult to harness this energy in regions prone to crustal movements and volcanic eruptions. While high end technology is used in determining possible sites from where this energy can be tapped, there is no 100 percent assurance that the results would be at par with expectations. The initial cost incurred is yet another deterrent when it comes to investment in this source of energy. Even though the supporters of this form of energy say that this is a clean source of energy, tapping the steam inside the Earth’s crust can disturb the methane stores beneath the surface and release it in the atmosphere, thus adding to the greenhouse effect. The administration has to look into all these geothermal energy disadvantages before working towards its development.

These were some of the most prominent advantages and disadvantages of geothermal energy that have to be taken into consideration before opting to invest in its development. You don’t quite need an Einstein’s mind to understand the positives and negatives of this source of energy. Even going through geothermal energy advantages and disadvantages for kids will tell you that there are as many problems as benefits of harnessing geothermal energy. More importantly, it has to be also compared with other sources of alternative energy sources such as solar and wind power. Just being in the initial stage of development, geothermal energy may seem quite promising, but the final results will only be ascertained after all the doubts pertaining to it are cleared.
