Everyday we sit and work with our laptop, watch TV, play with tablets, use the coffee machine, use the lights, etc. Electrical appliances and devices exist today in very large numbers and will keep on growing at a very fast rate. In order to meet demands for electrical power, fossil fuels have been the main force of producing electricity ever since the industrial age. As effective as fossil fuel is, it will not last forever due to the fast rate of consumption and increasing electricity demand. As supplies of fossil fuel dwindle, it has become clear that renewable energy will become the primary source of global energy. Of all renewable energy sources that are available, wind energy stands at the top. We had use wind to do work for us …show more content…
The picture in that book that I remembered the most is the one with a field of mirror shining directly towards a receiving end of the tower located at the center of the mirror field. That picture was dubbed as solar energy. Because that picture was the most interesting one that I came across, I went back to see what unit the picture was set in. I found out that picture was in the unit named Electrical Energy Sources. From then on I always wanted to see anything that is similar to what I saw from that textbook. All these years I did not spot anything that is remotely similar to that picture, however, when I did spot places where they generates electricity they all had smokestacks.
I then learned that there are two types of energy sources: non-renewable energy, renewable energy. I realized that non-renewable was much more popular than renewable energy as for the only other renewable energy plants that I saw was the Hoover Dam from 2005, and the wind farms in Austria from 2011. I then thought why are renewable energy so rare compared to the non-renewable energy counterpart. That all changed when I entered high school.
In my science class in high school, I learned something called total net energy cost. It means monitoring the how much the positives compare and offset over the negatives. In this case I learned the net energy cost of running different renewable energy and non-renewable energy. Non-renewable energy is very effective because it
In a growing world, electricity production is becoming a problem due to coal fired electrical plants releasing millions of gallons of greenhouse gases, ecological problems with pollution in water, and health risks concerning workers and people living nearby. But with new technology and advances in renewable energy sources, wind energy is becoming one of the most popular energy sources for many states.
The time has come, we’re running out of fossil fuels and we need an alternative. That is where renewable energy comes in; The best part about it is that it is renewable so it will always be available to us, and we can acquire this energy through solar, water, and wind power. There is a lot of controversy as to whether we should rely on renewable energy, because some say it is not cost effective. However renewable energy can pay for itself, is available nearly everywhere through various methods of obtaining it, provides numerous amount of jobs and economical benefits, and it will not harm our environment.
One of the fastest growing energy sources in the world, wind power is a globally advantageous renewable resource.
Imagine getting free electricity, or electrical company’s paying you instead of you paying them, today’s windmills just might make this possible. Windmills dating back as far as the 1400’s have been used to turn wind into useable energy for grinding and pumping. Today’s windmills turn turbines to make electricity. They are popping up all over the United States, but the United States is way behind other countries in the development of wind energy. Countries like Denmark, Germany and the United Kingdom are investing billions of dollars into wind energy, including off shore wind farms. Germany is holding the top spot in the production of wind-generated electricity. Denmark, being one of the smaller countries in Europe, produces twenty percent
According to the United States Energy Information Administration (EIA) as of 2016, Missouri had 659 megawatts of wind generating capacity online, another 300 megawatts being built, and substantial additional wind energy potential, primarily in the state's northwest.
Renewable energy sources, like hydroelectric, solar, and wind, have proven to be hugely ineffective because they do not generate large enough quantities of electricity (Canadian Nuclear Association, 2013). For instance, a total land area of 40 times the size of Metropolitan Toronto would be needed to generate enough power for the city of Toronto using wind energy (Canadian Nuclear Association, 2013). Moreover, renewable energy sources heavily depend on the weather when generating power. For example, hydroelectric generators require rainfall to flood damns and create flowing water, wind turbines require powerful winds to turn the blades, and solar panels require clear skies and ample amounts of sunshine to produce electricity (Solar Schools, n.d.). Thus, renewable energy sources become unpredictable and inconsistent without these weather conditions.
Specific Speech Goal: Show the importance on why we should change our ways and convert to renewable energy.
Renewable energy is an extremely popular topic in conversation, politics, and media. Consumers are interested because it raises real estate value, cuts power bills, and offers a tax break on homes equipped with solar panels. Environmentalists agree with renewable energy because it produces little or no waste products such as carbon dioxide and other chemical
When the new Southeast Polk High School opened they added many new energy saving products. This included installing geothermal heating under the high school cutting back on the cost of heating such a large building. Many new windows help save on energy used to light the building along with automatic lights that turn off after several minutes without movement. The new high school shows how easy it is to save money and help the environment. Renewable energy is good for all aspects of the U.S, providing jobs, economical growth, environmental cleanliness, and new research for improving energy efficiency. Therefore the United States should use renewable energy to benefit the economy and environment.
Renewable energy may seem like a daunting task, but the benefits to humanity could be incredible. Public uses of renewable energy range from transportation all the way to heating and cooling. Everything we use could become less explosive and less expensive. Cities with a high concentration of people could become safer and healthier places to live. Transportation could be converted to electricity dramatically, improving smog conditions. Global warming may or may not

“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush, who ran his entire Euclid Avenue mansion off of one for 20 years, which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn't rise a great deal afterward, this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose ‘fuel’ is free and will never be exhausted” (3) with the pros and cons not completely weighed out as to whether it will be truly beneficial or not. The two main issues regarding wind turbines are the environmental effects that they have and the
We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.
Wind Energy is a viable industry that has become a valuable energy source. The energy generated from wind is clean and efficient. The wind energy industry helps to ensure that electric demands are met, wildlife impact is minimal, the environment is not devastated, as well as creates new jobs during the construction of wind farms, daily operations, manufacturing components, and exporting components to foreign countries.
Wind power is a clean and renewable energy that, while at times unreliable, has very low upkeep cost and is growing at a rapid rate. While there is currently enough wind power to provide many times our current energy need, it is unfeasible in reality. Wind power utilizes the kinetic energy of air and uses it to power a generator to produce electricity. Even though dependence on wind power is impossible, it still can provide a strong, clean, quantity of power to supplement current energy production.
