Renewable Energy: Energy Around Us

    

During the past 150 years, non-renewable sources of energy such as fossil fuels and natural gas have decreased by a huge amount because all humans are using them as the main source of energy. This essay will explain how to use wind energy and the advantages and disadvantages of wind energy. It will also explain how wind energy would be the next main energy source that will give the world a more sustainable future.




First, wind energy is the use of wind turbines to convert kinetic energy to mechanical energy. Subsequently, electrical energy is generated from mechanical energy by the electrical generator. Additionally, wind energy is an emission-free source of energy because it does not release emissions that can pollute the air or water. Moreover, they do not require water for cooling the turbines.




In addition, wind energy has both advantages and disadvantages and I will explain them from all the perspectives. Moreover, the advantages of wind energy are Free fuel which means that they don’t need to be fueled at all. So they are one of the cleanest forms of energy because they don’t rely on fossil fuels as stated the point above, however, wind energy is mostly required during the production of material, installation, and construction. Wind energy reduces our dependence on Fossil Fuels. Wind energy is the cheapest form of energy source.




Furthermore, the disadvantages of wind turbines are dangerous to some wildlife like birds or bats whose habitats or migratory paths could injure or kill them if they fly into the blades. These wind turbines release noise pollution from their very loud noise that ranges between 40 to 105 decibels. This may cause negative effects on humans and all living creatures if we got too close to the wind turbines. Lastly, wind energy suffers from unreliable/unpredictable wind speed since the wind blows at a variety of speeds. It is hard to predict the amount of wind energy that can be collected at a given time. This means that suppliers and cities must have an energy reserve or alternative sources of power in case the winds die down for an extended period of time. This is called Intermittency, which is caused by the inconsistency of the wind’s speed.






As you might have known, fossil fuels and natural gas are the main sources of energy that humans worldwide use to generate electrical energy, however, they are both non-renewable energy which have a lot of negative impacts on the environment and the world such as air and water pollution and global warming emission. The solution to decreasing the use of both fossil fuels and natural gas is wind energy because wind turbines do not need any fossil fuel or natural gas, it just needs the wind flowing to the wind turbines. Thailand could be a role model to other countries because Thailand uses wind energy from the 2 main wind turbines at the coastal of 2.5 MW in Songkhla as a sea wind power plant and 2.5 MW in Nakhon Ratchasima as a land wind power plant. Fossil fuels and Natural gas can be reduced even more by connecting a wind turbine to the vehicle (boats or yachts) to generate the electricity for that vehicle while driving. Overall, it is believed that wind energy could be used as the main source of energy and reduce the use of fossil fuels and natural gas. For example, Denmark is the closest because it uses wind energy 47% out of all its energy sources.


In conclusion, wind energy could be used as the main source of energy and reduce the use of fossil fuels and natural gas, however, there are also a few disadvantages that we will have to fix future technologies and innovation.

Education



During the past few years, numerous parents worldwide have wanted their children to do organized activities in during their spare time. In addition, the students are stressed because they don’t get to do their hobby even it is their rest time. Personally, I agree with how people or guardians should let the kids do their leisure activities or work on anything that they like during their relax time. In this essay I will explain about the children activities developing and improving them both physically and emotionally.




First, it is my belief that the kids should be able to do whatever they want during their free time, because this helps them to create and develop their creativity and other skills. For example, if they like to play Lego buildings, it will help them to develop their architectural design skills which could be used in the future. Furthermore, this would keep them relax and it is also a time for them to recover their usage of their brain while earning the knowledges from the school education system. This is very important for kids this age because it is the part where their brain is developing the fastest in their life. Also, referring to the ideology of “Learn Hard, Play hard”, this is true because we both earn experience and skills from their leisure activities.



Second, I think that letting the kids do whatever they want during their free time is also improving them physically. For example, if the children go out to exercise or play sports. This helps build up their health or if they get injured, they also earn the experience of pain and would make them stronger and ready for the harsh world in the future. Additionally, if they play a team sport this builds up confidence, teamwork, and soft skills. These skills are very significant for them when they are learning or working in the future. This gives them the habit of not giving up and the sportsmanship to help them be more of a good citizen.




In conclusion, numerous parents worldwide have wanted their children to do organized activities in during their spare time. This is why I believe that we should let the children do their favorite activities in their spare time. Moreover, this helps the children
to gain skills and experience in these activities that are crucial for their life in the future. I have explained the reasons to support my opinion in the essay.
